PWM Fan for P7N Diamond

I was thinking to swap my "Scythe S-FLEX 1600RPM Ultra Quiet" fan that is currently pushing some air through my Thermalright Ultra Extreme to some 120 PWM fan. I don't actually want to replace it, I was more thinking to keep that Scythe to use it with a push & pull method on my TRUE 120 (PWM to push and regular one to pull). But before I do that I have few questions:
1) Is there any actual difference between regular fan & PWM fan by that I mean performance / efficiency / energy wise? Is there any benefit?
2) Will I somehow be able to control both of those fans, (I wouldn't want to have them on full speed at all times)
3) With which PWM fan should I got with?
I did find few quite promising fans. Maybe someone has more experience with them? Anyway here they are:
Nexus 120mm PWM Silent Case Fan more details from here http://www.nexustechnologyusa.com/c/ntusa/nexus_pwm_fan_120.html
Scythe 120mm "KAMA PWM" Fan more details from here http://www.scythe-usa.com/product/acc/020/dfspwm_detail.html
Arctic Cooling 120mm AF12025 PWM more details from here http://www.arctic-cooling.com/fans2.php?idx=108&data=6&disc=
With the "Kama PWM" I would have to do some customisation as it has closed corners. The other 2 seem to have a open corners. I really wouldn't like to bother with that Schyte but if its best of those three I would buy that one.
All ideas and thoughts are appreciated

The thumb of airflow rule is to maintain a good balance of air (cfm) flowing in and out.
This is to say that if you have a fan that is capable of pushing in 30cfm of air into the system, the balance point is to have a fan that is capable of pulling similar amount or slightly higher amount of air out of the system, example 30cfm ~ 35cfm. You must not have overflow of cfm flowing into the system as this will cause warm air to circulate and stuck in the system. The same goes for the amount of air being pulled out as the system will be vaccumed in a way if there's not enough ventilating holes for air to flow in quickly.
Just rememeber that the cfm demand for both inlet and exhaust fans must be maintain at good level. Next will be the cooling circumference and fins. Wider circumference will help to spread the airflow to the hardwares within the system, and well designed fins will help in creating less decibels while maintaining good airflow cfm.

Proper Planning for P7N Diamond

After several years of a desperately inadequate computer, I have decided to upgrade. Instead of a simple and easy (but less powerful) upgrade, I decided to build my own. I'll be frank; I have very little idea what I'm doing. I know possibly a little more than the average person, but I possess almost no in depth knowledge. I've selected the parts I wish to buy (haven't purchased yet), and I'm simply finishing up proper research and planning before I go ahead and make the financial commitment.
Here's the major components of the build, at least the ones I'm moderately concerned about.

Q6600 Quad is compatible, from what I've seen from a few other purchasers of these two there have been a few problems. Considering the Mobo is one of my biggest investments of the build, I want to make sure it can work with everything.
I am NOT CURRENTLY concerned with Overclocking and SLI (maybe further down the line, not right now).
To put it simply; using the P7N Diamond Mobo and the Q6600 Quad core CPU, what are some of the snags I might run into? Will the mobo be able to recognize the CPU right off the bat? Will I need to Flash the Bios? If so, I will need a Floppy Disk Drive, correct? Is there anything severely wrong with the PSU/Mobo/CPU/ETC that would require me changing anything?

A poster above is looking for P6n diamond it is available new from a Dealer on Ebay about 79.00dollars Shipped.i purchased an Asus p5e-3 premium wiFi open Box for 150.00 shipped 3 months ago no issues.he also auctions open box p6n diamond but charges 14.95 but people have won with 40.00 and it averages 50.00.
well i am typing from a P7n running a Q9550 2gigs OCZ 1150 running at 800mhz.No luck whats so ever getting past
2775 overclock.very frustrating but I probably have the original bios.i bought this on ebay at an Auction unopened.It was thirty dollars less with shipping than NewEgg even with the rebate they had.
this a great board i hope and I have to download the Latest Bios and try again.if I am still stuck will have to buy a Q6600go and fallow the various successful overclocks that are listed as i want a modest 24/7 stable overclock at 3.6.
I considered the P6N but having the crystaliser built in pluss the overheating issues with 680i boards coupled with the memory burnout issues decided to spend more money as I am a Semiprofessional Dj and needed something that will last me at least five years running overclocked.P7n has an extraordinary chipset cooler set up.i run old 486/386 fans blowing over everything.
I run two 8800GTX 768m and run 3 22inch lCds and 1 DLP projector and I am driving through the Soundblaster 3 5500 watt amps.MMX6 dj program waves Plugins.Having the ability to swap out the audio Card to another CSB specificaly for recording and midi key board was a Pluss.though could have done with that with the P6N diamond.
Part of my agravations with this board i think is that I am running Xp64 Bare to the bones as fast as linnux but a few minor issues like Asio crashing.i do not like vista but she is triple boot xp64 xp32 and shoosh dont mention it 32 bit 8&56^.
Hey was looking at the quad I think q8500 forgot basicaly same price as q6600 but tired of the hassles would prefer just to get it over with.read on other boards at idle q6600 at 3.6 runs 20-22c.
My board definitely has issues with 45n processors. At idle 49-50c stock speed on a Modded OCZ II vendetta monster cooler heat pipes with TWO loon fans in push Pull??Well time to cut the Dribble and see what BIOS's are available.Probably I put the wrong ram into this also.was a Bargain 19.00 shipped after rebate.expected the old style OCZ ram and got the new one same heat pipe desighn nicer lines.
amazing still eist is running only 5percent CPU usage temps stable but high.Going to crank up my audio editor reaper hmm let me ripp some CDs at the same time and see if this CPU will crank up.ah convert some vidio at the same time!
this board computer is also a DAW.My asus is used for vidio editing running a pair of Akimbos.and q9450 and a xifi .CSB of course!Building another asus p5k wi fi to run connect to 8 wireless cameras so put this q9550 into the Asus vidio editor take the q9450 and get a q6600 for this board and be done with it.
Ah almost forgot the MSI update software etc does not work in my xp64 nlite.
just realised install it on the other partitions!!
forgot to mention the hassles and hours spent installing drivers on this xp64bit build.still have a minor issue my ethernet is labeled ethernet port then ethrnet port 2? and Xp64 keeps trying to Install a 3rd one on bootup?Afraid to uninstall #2 and go through the hassles I went through last week.I guess xp64 is not supported yet on this board just Vista 64 .Which I have on an Hp 9200t media center.i cannot use foul language as to how frustrating Xp64 Vista is to me.

Here is the deal. I'm trying to boot these http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2458326&CatId=0
No matter what I get a no post. Tried 1 stick in each slot and the samething. Now my OCZ SLI DDR2 800 2x2 boot without a hitch.
Any ideas what I can do?

The image is a bit blurry, but looks like they are from the same revision & batch which is good. Populating all the dimm slots with the P7N always was a challege on the MC. Most likely going to have to tweak a lot of stuff, & it has been too long since I did one of these. If the thread is still here, it was titled P7N OC & QX9650 or something like that. Found it. Maybe something there to help with what settings may be involved. https://forum-en.msi.com/index.php?topic=118301.0
In fact, you might want to use the 'Search Button' for P7N Diamond threads. May be even more information that will assist you. Someone may have tried those RAM sticks 'back in the day'.
I'll do some searching in that thread. Thanks for that. I'm rusty as hell with 775 systems. I'm so use to X58 that I'm like ummm crap. So relearning sucks!
Here is a close up shot of the specs.

HELP! - Voltages for Overclocking Q9450 on the MSI P7N Diamond (780i chipset)

Hey. I fully understand the settings as far as frequencies go, but am a total voltage newb. No matter what I do I cant seem to get a stable vista load up with my voltage settings.
Please help me by providing suggested voltage settings for my hardware.
CPU - Intel Core2Quad Q9450
RAM - 6 gigs of DDR2-800 rated at 2.1V
VIDEO - Dual Nvidia Geforce 8800GT's in SLI
MOBO - MSI P7N Diamond, based off the Nvidia Nforce 780i SLI chipset
My cooling is sufficient, and I have the BIOS version 1.2
I also turned off all of the overclocking not friendly functions, example: spread spectrum, and DOT, ETC....
I am trying to run my CPU at 3.2 GHZ (400 mhz before multiplier)
my settings I want are (as shown in the P7N bios)
System Clock Mode - Manual
FSB clock - 1600
DRAM clock - 800
Please help me by providing the proper voltages for my setup
Everything I need is marked by "???"
CPU Voltage - ???
DRAM Voltage - (already have, its 2.1)
NB voltage - ???
SB voltage - ???
NB Memory reference voltage - ???
DIMM memory reference voltage - ???
Memory terminator voltage - ???
CPU GTL reference voltage - ???
NB GTL reference voltage - ???
FSB terminator voltage - ???

PCI Expander PLL voltage - ???
For the sake of you not typing too much, if you specify voltages, any that you do not specify will be assumed to be left at [AUTO]
PLEASE help me by providing some voltages for me, as I have absolutely no clue what to put for them. If you have any questions about my hardware feel free to ask, and any help is GREATLY APPRECIATED

adjusting gtl ref. voltages isn't very difficult, but it is probably best to learn the basics first.
So, basically, increase the fsb a little. So, for example, from 1333 to 1400. See if it's stable, if it isn't try bumping up vcore one notch and try again. If not try Northbridge. Then later move on to stuff like the fsb term.
Test stability using prime95, there is a 64-bit multi-core aware version floating around somewhere. Try the ftp server linked to in the "hot use prime95" sticky on here.
Tbh with your OC you shouldn't need to touch any other voltages, or really use the gtl ref settings. What exactly is "sufficient" cooling though? Stock?
*EDIT: on a side note, just so you don't think I'm deliberately being awkward not telling you specific voltages, they wouldn't do you any good. Every cpu/mobo can handle different freq. at different voltages. Also, use cpu-z to check on your actual voltage and make sure you don't raise it beyond 1.3625 (I think that's right, it's 1.36something anyway)
Thanks for the tips. The reason I wanted to jump straight to FSB 1600 is because the MSI p7n is really picky and only likes 1:1 ratios.
My "sufficient cooling" is an aftermarket heatsink, high performance thermal paste, and MASSIVE airflow through my case. If you want specifics, its the Scythe Zipzang

CPU Voltage - No one can tell you this.
NB voltage - Depends on what frequency you want
SB voltage - What's your HDD setup?
NB Memory reference voltage - Auto
DIMM memory reference voltage - Auto
Memory terminator voltage - Auto
CPU GTL reference voltage - Depends on speed and other voltages
NB GTL reference voltage - Same as above
FSB terminator voltage - Depends on CPU voltage and CPU/FSB clock speed
SB sleep mode voltage - Auto
PCI Expander PLL voltage - Auto
My recommendation is do some reading. Guessing leads to dead hardware.
6GBs smells like mixing modules... Or do you have 3 modules?
First of all, I already stated the frequencies that I wanted in the top post, and fairly clearly at that.
CPU shouldnt be too hard to figure out, as there are very few to choose from. I'll try to get back to you on that one
I have 5, 7200rpm SATA 3.0 drives. It sometimes runs with only 4, as one is a hot swap.
My ram IS mixed, unfortunately. I'm using 2x 1gig sticks, and 2x 2gig sticks. However, both sets have heatsinks, and are rated at 800mhz, 4-4-4-12, 2t, timings. (2.1v)
I AM running them in dual channel.
If this helps you suggest voltages please do, If not, then I will just have to start trying using nihilkrist's suggestions.

New Need Sink needed for MSI P7N Diamond nForce 780i SLi (Socket 775)

Hi Guys,
I've been having a problem with my machine where it will be working away as and then suddenly restart. I haven't been able to pin point the problem as it can happen regardless of applications or load thats on the machine. I've also run a couple of app's to check the RAM and its fine. The only thing I've been noticing is that the 4 cores of my Q6600 seem to be running a bit hot. On average on Idle there running between 45-55oc. Does this seem normal? I'm thinking that the cpu might be over heating when I'm running apps. I've seen one of the cores up around 68oc when under a bit of load. I'm using the stock heat sink at the moment and would like to cool things down it see if that helps. Can anyone recommend something suitable for my motherbroad.
Thanks
Garret

Intel Core 2 Quad Pro Q6600 "Energy Efficient SLACR 95W Edition" 2.40GHz (1066FSB)
MSI P7N Diamond nForce 780i SLi (Socket 775) PCI-Express DDR2 Motherboard with Free Creative X-FI Card
Thermaltake ToughPower 750W Modular Power Supply
My Q6600 (also G0/SLACR but don't know what you mean by "Pro") is OC'd to 3.4GHz and has had no problems running stable. Highest temps during OCCT/Linpack and LinX/Linpack peak at 80C 1st/2nd cores - 76 C 3rd/4th cores. Other tests (e.g. Prime95 small FFTs) run much cooler. I've run 2hr+ linpack tests with no errors, so I don't think you need to worry about your temps yet.
However, may I suggest that you check into is your power supply, in particular the modular connections. I had the ToughPower 750W Modular before upgrading to PCP&C. I noticed that the ToughPower's modular connections had a tendency to be just a tad loose. They wouldn't dislodge but they had a little bit of play. I could jiggle them ever so slightly while they were connected. As a result, the CPU power cable (8-pin/4-pin) would cause a restart upon the slightest disturbance or sensation. I've since discovered that modular connectors also affect the efficiency, power noise levels, and overall performance of a PSU. All in all, I plan to avoid modular connectors entirely going forward. Many newer cases have excellent cable management features and even old-style cases can be cleaned up with a little planning and effort. So the modular cabling advantages don't offset the severe disadvantages. Even if your problem isn't due to the PSU, it's something I'd recommend considering replacing.
Good luck. Hope all the suggestions are able to help you nail down and resolve your issue.

P7N Diamond - E6600 - Looking for 3.1 / 3.2Ghz

I can get 3.0 stable with ease by just adjusting the FSB to 1333, manually setting my ram to 1066 (what its rated) and manually setting timings to 5-5-5-15 at 2.1V
Tweaked the VCore +0.0125 and it runs fine.
If i go any higher than that i post, but freeze / restart upon windows booting.
Specs:
MSI P7N Diamond
E6600 2.4ghz (currently at a very stable 2.7ghz)
2x2GB OCZ PC-8500 1066mhz [email protected]
BFG 8800GTX
150GB Western Digital Raptor SATA 10,000RPM
200GB Western Digital IDE 7,200RPM
Huntkey 550W PSU
Kinda new to OC'ing but did manage to get this processor stable at 3.1 on an Asus IP35 and some PC6400 RAM so know its capable. Just cant figure out the BIOS options with this Mobo.
Thanks in advance guys.

Dude i have the same spec that you have but i am using 2GB of RAM .... And i am total Noob when it comes to OC ...... wat settings should i do in Bios Or manually in Dual Core centre to get it to 3.0 Ghz . Thx
Go into the bios and go to the Cell Settings menu.
In there you need to change the System Clock Mode to manual and it will then show two further settings for the CPU clock and RAM speed.
Seeing as you have different RAM to me make sure it's specced to run at 1066mhz instead of 800mhz before changing the next setting.
Change the CPU clock to 1333 and the RAM to 1066 (it'll read out at 1067, the 1 extra mhz wont hurt anything.
Now you'll need to go down the CPU voltage and tweak that up by pressing the + key to add 0.0125v to it and bring the DRAM voltage up to 2.10
Thats all there is to it. If you get instability add a little more voltage to the CPU but keep an eye on temperatures as you go, do it in tiny steps and run some testing software like Super Pi or Prime.
If at any time your computer refuses to POST just hit the little black reset button on the back of the I/O ports and start from scratch.

MSI P7N Diamond Burnt Out!

Hi,
It's now been a good few weeks for me trying to set-up a new computer after having replaced the motherboard a couple of times and buying better power supply etc. But I've now got a new issue with this P7N Diamond and it's the second time it's happened (already RMA'd it once before with same issue). Each time it's happened I've only had the basic items connected, power supply, motherboard, graphics card, memory, cpu and fans.
Basically what happens is that the computer powers on for a few seconds but there is an immediate burning smell from the motherboard. When I removed the motherboard I found that a thin strip of copper around the under side edge of the board, almost directly below the bottom fan connector (SYSFAN4), has burnt away exposing the cooper itself and split. I've checked for anthing shorting the board in the case and all the case/motherboard screws are in the correct place.
When it first happened I thought maybe its the PSU (I used my older Antec 470W on the first RMA'd board) or a faulty board, so I upgraded to the Corsair PSU and got the board replaced, but its now happened again!
Obviously I don't want this happening again so any idea what would cause this?
Would it be the fan connected to SYSFAN4? It's a Scythe Fan rated at 0.26A and I think I had it connected both times when the board blew. If it was the Fan how would a board allow this type of thing to happen, should it not have built in protection to stop things burning out like this?

All my fans are plugged into the P7N. All of them came with the Cosmos case except the CPU fan which I bought seperately. So far (knock on polycarbonate), no "charco' for a mobo". (All fans are 120mm including the one I bought)
I read that the Cosmos although quiet is not too good at staying cool and lots recommended changing the default cosmos fans with better ones, so I changed them all to Scythe fans except the CPU fan, which is an Arctic Cooler 12 PWM Fan, as the Sycthe's don't have four pin plugs.
Quote from: Pchas01 on 10-May-08, 02:24:34
And, curious, why are you plugging a Scythe fan into the #4 conector? There are three others closer to the CPU if you're cooling the CPU). I use all 4 connectors with no issues at all. Last question, is it a 5v fan, 12v fan..? Ah, good luck with the Stryker if that's what you want..it's a good board.
I have about five Scythe Fans and one Arctic Cooling CPU Fan. The AC CPU Fan was using the CPU Fan connector and the other four connectors had the Scythe fans attached. I just thought it had something to do with the #4 connector because the burn out was so near. The Scythe fans are 12v, could that be the reason?
Yeah I got the Striker II board now, but seem to be having the issue I original had with my first MSI P7N board with the Coolermaster PSU it just flashes on for split second and cuts out. I thought having this Corsair 750W PSU I wouldn't have that issue any more. As soon as I plug in my cheap gfx card it works fine! I just seem to have no luck at the moment. (Yes I've got the gfx power plug in )
Quote from: NovJoe on 11-May-08, 12:57:46
Sound like a surge shorting either from the fan or the chassis.
Try removing some of the unneccessary standoffs and see if problem re-occurs. 2 boards can't have the same problem repeat that easily.
I only had the standoffs for the nine holes in the board so should not have had anything shorting it out.
I got a ASUS Striker II now anyway and so far it works, but I'm only powering the CPU Fan from the board now, all the others I'm going to do direct through the PSU. Just need to get it working with Geforce 8800GT now.

Question regarding Antec Power Trio 550 and GSkill PC8500 RAM on P7N Diamond

Good Afternoon,
I recently built a new machine using the P7N Diamond System Board. Here are the current Specs
Intel Q6600 Processor
G.Skill 2 GB PC8500 RAM PK Series
Seagate Barracudda SATAII HDD
GeForce 9600 GT OC 512M (BFG TECH)
Antec Power Trio 550 PSU
I have 2 questions, I configured the RAM in my bios to run at 1066 with manual timings that the manufacturer gave as CL5-5-5-15 and while it is runs at 1066 I'm only getting a Vista Rating of 5.0 for the ram while everything else is at 5.9. If anyone is running G.Skill RAM on this board and have gotten better numbers please share with me what you did to achieve it.
Second Question, I noticed there was no dedicated power supply fan connector on this MB, in order to take advantage of the Antec Smart Fan technology do I need to plug this fan connector into a specific system fan connector port on the Motherboard??
Thanks in Advance

Ignore the Vista rating, it is not accurate to beging with. Run a memory performance test with some benchmark tool and compare the numbers there.

P7N Diamond - Problems with different things

Hi, n0id here.
I have recently bought a computer in parts (from different web shops).
Yesterday I finally got the processor and was able to build the computer, so I started building the computer.
After about an hour of mounting the parts, I decided it was finished, so I powered it on and watched it boot.
The first thing I noticed was that if my USB Keyboard was plugged in, POST would freeze at "Initializing USB Devices".
I figured it was only temporarily, so I switched to a PS/2 Keyboard, which helped.
The next thing that happened was the BIOS was not able to find my Hard Drive (SATA). I was wondering if because the motherboard support SATAII if SATA drives wheren't compatible. I opened the case and saw that the SATA cable wasn't plugged in properly. So after putting it back in properly, I booted the computer again.
So, now that POST was running OK and BIOS found all my components, I decided to install Windows XP.
After about a minute of reading the cd (windows initializes the installation program in DOS) it stopped reading, and the computer freezed. Finally, It got to the point where I can partition the HDD. But the computer would always reboot at this point. I haven't figured out why yet.
So I connected the HD to my old computer and installed windows here. That worked.
I reconnected the HD to the new computer and after windows loaded, I got a blue screen and the computer would reboot again.
So I decided to remove some of the components. I removed one RAM module, the soundcard (Creative XFI Gamer) and unplugged the 120mm back fan. At this point I was able to format the drive and install windows without a problem.
So I decided to insert the components again, but when I then started the computer, I didn't get a picture on the monitor. I tried with a different monitor and with a different graphics card, neither of which made a difference.
At that point I went to bed because I had already spent seven hours trying to figure things out and it had gotten very late.
So now I am here asking for any guidance.
My computer specs are:
MSI P7N Diamond motherboard,
2x 1Gb Kingston 1066 Memory modules running at 1.8v,
Geforce 7900GS,
Creative X-Fi Gamer soundcard,
Intel Q6600 G0 @ 2.4Ghz,
Thanks for any help.

Hello again.
I am trying to overclock my Q6600.
Everytime the FSB is over 267mhz (2.4ghz CPU Clock) I get a BSOD: "IRQ_NOT_LESS_OR_EQUAL".
Then it's dumping the memory and restarting.
When Windows starts up again, the FSB is back at 267mhz.
I am using the application MSI Dual Core Center, that followed with my motherboard.
I noticed in this application that memory voltage was set to 1.9v. The memory modules I bought are 1.8v because when I bought the MSI P7N Diamond, it said it only supported 1.8v memory. aww :S
Anyway, my full specs are:
Intel Q6600 (G0 stepping) - 2.4ghz
MSI P7N Diamon (7510) Mainboard
1x 1GB Kingston (KVR1066D2N7K2/2G) memory modules, 1.8v, 1066Mhz,
Antec NeoPower 650 (650W, 3x 12v @ 16A)
GeForce 7900GS
Creative X-Fi Gamer
Win XP Pro, SP2.
I am going to browse around the forums for similiar problems, though I thought I'd post this now.
After browsing the forums I've learned a few things.
My Q6600 has a VID of 1.3250 and the box it came with said that 1.35v is the max. So I have changed the voltage to +0.0250 and was able to clock the CPU to 2.67Ghz without a problem (temps are 33 - 36 celcius on idle.)
My question this time is: even though the box says 1.35v max will I safely be able to set the voltage higher than that?
I would assume that Intel is setting a maximum that is lower than the actual max, just to keep the processor safe. But I do not know stuff like that :P
My target is 3ghz, and if reaching that clock means I need to apply a greater voltage than 1.35v, and it isn't safe; that would totally suck.
edit,
To achieve 3ghz I supplied these settings in the BIOS:
FSB: 1333 Mhz
DRAm: 800 Mhz
EIST: Disabled
Multiplier: x9
Nb voltage: 1.35
FSB Term.: 20
CPU GTL Fef: 5
The cores are currently at 36-38 at idle, compared to 28-32 on stock clock.
I will see if I can buy some extra fans to put in the front to blow cool air into the case, and maybe buy a new cpu cooler.
Btw, the vCore is 1.3v (and it's also set to auto in bios).

P7n Diamond, Corsair TWIN2X4096-8500C5DF, speed problems

I have been having various problems with both the RAID and memory speeds in this system. The RAID problems (DEGRADED RAID 5) come and go but my current primary issue is that the system will not run with the memory set at its rated settings:
1066 MHz
5-5-5-15
2.1v
The best I can get it to clock up to is 1000 MHz at which the system will run for about 5 to 10 minutes before locking up. I ran memtest for 2 full cycles at this frequency and no problems were detected (i think it was run at 1000 MHz, it's been a while sorry).
The system is currently running stable at 800 MHz (the speed it sets the memory to on auto). It will also run stable at various points higher up to the 1000 as I mentioned above but since I have never heard of someone running their system anywhere between 800 and 1066 (unless they were overclocking) I figgured it would be most healthy for my system to run at the 800 and no higher until we can get this figured out.
I have seen that this board sometimes sets the wrong automatic voltage on some people's 45nm processors. My x3350 is a 45nm proc but i'm not sure what its voltage is supposed to be, i just left it on automatic... maybe this has something to do with the problem?

Hey, thanks guys. Wow it's amazing that nobody had said anything about the 1066 memory to me before (like when i was building the system and throwing together a parts list).
The only problem they could find with my config on eggexpert.com was the motherboard... they said it had problems with the raid but didn't quote or point to any sources so i just did a google search and when i couldn't find anything to back up their problem statement i just blew it off. Guess it's the last time i'll ever make that mistake.
Either way though, MSI says it should work fine. So if it doesn't, shouldn't there be something that could be done? You would also think that I could find someone out there who's WAY smarter than me who has had this same raid problem and figured it out and gotten it to work. I'm sure there's plenty of guys out there who are using this board with a raid 5 as well, so maybe i'm just doing something wrong? I have always had good results with MSI and I really don't think it should have to come down to finding another mobo manufacturer.
Oh, and for anyone who might suggest rma, it's too late for that. Believe me, i would if i could.

Hi everyone,
I've had my board up and running for around a week now and up until Saturday it had given me only a few minor problems, the first of which was a BSOD when trying to install the Jmicron drivers and the driver s for my X-FI (they do not seem to like each other). I eventually uninstalled the Jmicron drivers and disabled the controller in bios which seemed to do the trick.
For a while after that everything seemed fine got my various games installed all of which seemed to play fine ( TF2, HLF2 (EP 1 & 2), Stalker, X3). Then on Saturday I decided to install the Crysis demo and for a short time all was well, then my system just rebooted, no BSOD no error just restarted to windows this happened again and again. I also bought COD4 and the same happens with as well never in the same place just random. It also rebooted once during a norton virus scan when tried to enter My Computer
My system is running cool enough I think I have 1 105CFM 120mm intake fan, 1 side intake fan 80mm and 2 55CFM 80 mm exhaust fans the air is only ever slightly warm and that was after playing HL2 EP2 for 2/3 hours.
I am at the moment running prime 95 and so far after 3hours all is well, I am also running X3 demo (@ max settings 4xaa 16xaf)in a continuous loop in the background as well to try and trip my system up but at the moment no reboot.
Any Ideas?

Give this a try.

You may be one of the ones like me and a few others that can only run this board stable with overclocking the cpu to 3ghz. That should be easy to do even on air, but keep an eye on it. I was unable to get viper, g.skill or patriot memory to run at 1066 with my board, at least so far, so you may have better luck than I. Except for getting your memory to work at 1066, I can almost promise that this will work for you. I also had the problem with the jmicron drivers and do not use them now.
Word of warning, too much playing around with this can lead to OS corruption, so be easy.

P7N Diamond board won't post

I have a P7N Diamond board. About 3 weeks ago, I had more and more trouble with the computer. I thought it was a memory problem, because it failed Memtest. I initially had Mushkin memory and bought Crucial, specifically compatible with the board. It worked briefly but then failed to boot. I tried the Mushkin memory again and had some smoke, the memory got hot, and after that the board failed to post. Thinking it was a problem with the motherboard, I sent it in and received an RMA today.
I set up the new board with the Crucial memory that I had. I am fairly certain it is wired correctly, but the system fails to post, though it does turn on with all the fans. Where should I go from here? I have a Intel Core 2 Duo processor, E8400 processor, Zalman fan, compatible Crucial 2 x 2 memory.

Please provide links to the datasheets or manufacturer's product sites for your memory modules.
For futher testing:
Please use one memory stick only (!) and make sure it is not running faster the DDR2-800. The voltage should not exceed 1.95V for now and Spread Spectrum should be disabled.

although it said on the memory that it was 2.0/2.1 volts.
Such standards do not exist. DDR2-1000 or DDR2-1066 at that voltage level is an overclocking/overvoltaged rating. Such settings are not necessarely stable.
Quote
After that, the computer would recognize the speed on it as 800, although both the memory and the board say they support 1066.
DDR2-800 modules that need to be overclocked and overvolted to meet the promised ratings, are not real DDR2-1066 MHz modules (7-7-7-x @1.8V). With such sticks, stability problems are always lurking behind the corner.

Aftermarket CPU cooler to fit P7N Diamond

Is there anyone who can recommend a good aftermarket CPU cooler that will fit on the new P7N Diamond?
Best regards /Pär

I'm sorry!
I missed to tell you what cpu I'm planing on using. Hopefully the new Intel Wolfdale: Core 2 Duo E8500 slightly overclocked.
I've read about the Thermalright Ultra-120 eXtreme. Seems to be a very good cpu cooler.
Any recommendations on a good 120mm fan for it?
The goal is a not to loud computer..
Any other recommendations....that will fit?
Regards! /Pär

P7N Diamond heat issues

I got my GTX 275 FTW in yesterday and while my rig is pretty screaming now, I'm having some heat issues. My profile contains all my specs and settings. I was hitting temps of up to 66c or so on my CPU when playing Grid at 1920x1080 with full AA/AF turned on yesterday. I've got a Cosmos 1000 case, which is quite silent, but not the best at moving heat, although it has a good number of fans.
I installed Nvidia Precision tool and set my fan to 70%. I'm hoping that helps some. Is there a way to crank up the fans any with the P7N diamond mobo? I've checked speedfan and it shows my CPU fans at 100%. I'm not sure about PSU or case fans and if there is any way to crank them up some. Any advice on maybe cooling it down some? Also, any suggestions on maybe tweaking my bios settings? I had a hell of a time getting the thing to run stable, as I had to OC and crank up the voltage to get the thing to even work out of the box. Thanks!

Well, this temperature limit is not defined for the Core Temperatures, but actually for the so-called "TCase" temperature (temperature measured at/in the geometrical center of the CPU's own heatspreader). There is no sensor there, so you can't really measure it anyway.
The limit for the Core Temperatures (TJunction) is much higher (Core Temp should show you the TjMax/TJunction value). It is usually around 95-105°C for a Quad Core processor.
Thanks for the info. So what would you think is a good "max" Core Temp temperature to go by before worrying? Obviously you would prefer to stay well below the TjMax value I would think... Also, what about GPU temp for a GTX 275 or do you know? I really appreciate the feedback by they way. It helps a lot.
I have also been worried about some of my bios settings, but have been unable to move to a new bios because I'm not sure how to convert the % based values to the more meaningful ones used with later revisions.. but alas that is another topic in and of itself.
