P7N-Diamond fails to even P.O.S.T/unable to enter the BIOS

Hi,everybody out there......Recently purchased a P7n-Diamond mobo hoping to build a gaming rig.Alas..upon connecting all the necessary peripherals and powering up the system....there is no displat...no beep.Tried a barebone test with intel q6600,corsair 1gb ram and a zotac nvidia 8800gt card...yes the psu is coolermaster 1000watts.Upon powering up it is seen that all the fans are spinning smoothly...little leds are all glowing....no beep is heard....no display is seen.....no P.O.S.T..........cannot enter the BIOS hence.
Any angel out there with helping hands please

Tried outside the cabinet also...cleared the cmos...tried to boot only with cpu cooler.an8800gt card ,1gb ram( Corsair ).Same case...No..post ..
Even tried with the same configuration in my spare P5n-e sli mobo there it posted fine.
Beginning to feel that the mobo is defective.
"tried to boot only with cpu cooler"
You need a CPU as well
Can you try with different PSU too?
Also check mainboard CPU socket for bent-ed pins

P7N Diamond rarely POST's

Hello all!! I’m having a problem with my PC booting. I had a stable PC for about 8 months (see sig below). Then I changed my video cards from dual PNY 9800 GX2’s to dual BFG 285 GTX OCX cards. Unfortunately I had some problems with the BFG cards and had to keep RMA-ing one of them (this is a long story). Regardless, the cards are fine now and the problem was corrected (this was a problem with the card(s) NOT my system).
Anyhow, along the way my system stopped POST-ing. I turn the system on, the lights go on, the fans whirl and I can hear drives spinning up but nothing else. I can do a hard re-start and the system will eventually turn on after 2 – 10+ attempts. If I reset the CMOS using the back button (with or without PSU plugged in) it turns right on BUT I have to reconfigure everything.
I’ve tried a TON of things in troubleshooting this thing and nothing works. I’ve tried reinstalling the BIOS and even that didn’t work. I didn’t do the BIOS update in DOS, I did it through Windows with some software. I would like to do the DOS install but I can’t my system to boot to a USB (I used the program I found on this website- the USB prep tool… I only get some sort of “NO MSI Product installed” error)
I’ve changed the battery on the board (twice) with no luck either. Checked all my connections, etc… My BIOS settings are all standard, no overclocking. The only thing I have going is RAID.
Needless to say, I’m running out of ideas… any suggestions
Thanks in advance for any help!!

First point that needs to be stressed is it's a safe practice to avoid updating any BIOS while in Windows. In fact, you should never attempt flashing BIOS from within Windows, and you probably should just uninstall MSI LiveUpdate. MSI should go so far as to discontinue it for the sake of all users. On the bright side, it looks like your BIOS update succeeded without issues (system is not bricked).

When you say BIOS settings are all standard, does this mean you manually set each parameter to a "standard" setting? Did you perform a CMOS reset after flashing BIOS? Did you enter the BIOS/CMOS menu and invoke the "Load Optimized Defaults" or "Load Fail-Safe Defaults" option? Could you please list the current values in your Cell Menu? Ironically, the P7N Diamond has a reputation for misbehaving under "default" parameters. With the earlier BIOS versions, many users have reported needing to apply a slight overclock (at minimum) in order to have stable POST and operation. It seems counter-intuitive that stressing the mobo would improve the operation stability, but that was the story. I'm still using a 1.2beta BIOS, so don't know if the more recent versions have addressed this. But it would be useful to know what parameters your system is trying to POST with (examples in my signature).

MOBO: MSI P7N Diamond (1.3 BIOS)
CPU: E8500 Wolfdale Core 2 Duo @3.16 GHz (no OC… yet)
RAM: 8 GB OCZ Reaper 8500 (@ 800MHz not 1066MHz)

PSU: 1300 Watt (I can’t remember the name, shame on me!)
Lastly, could you provide some more detailed specs on your PSU? The 1300W sounds impressive, but sheer wattage doesn't necessarily imply a sufficient PSU. This is especially relevant for a system with dual 285GTX cards, 8GB RAM, and 4xSATA hdd. In particular please state how many +12V rails your PSU has and the maximum amps per each rail, max amps combined for all rails, and max amps total (for all voltages). My concern here is that the real root of your problem may be related to the PSU. You stated that the system ran perfectly before you replaced your previous video cards. I'm wondering if the new cards are over straining your PSU and causing intermittent issues at POST. Do you have 4pin ATX or 8pin EPS power connected to your mobo?

MSI - P7N Diamond ESATA doesn't work under XP

I have 2 P7N Diamond motherboards and am running XP Pro/sp2.
I have never been able to get the esata ports to work. I have spent the last 4 months RMAing boards back and forth to MSI. I have tried at least 4 motherboards, 3 esata external drives, and 3 cables (all 6 feet).
Sometimes on the upper port (lower port doesn't work at all), the drives get detected in bios as gibberish. Other times it is listed correctly in post, but then I get a "9th slave hard disk error". I press F1 to resume, enter the bios, and the drive shows up. The drive never gets detected in windows, however.
In bios I have the Extra IDE/RAID Controller enabled and RAID mode is set to IDE.
In XP I have the JMP36X IDE Controller installed.
During all this time, MSI Tech Support has insisted that I am doing everything right. I called them last night and they mentioned doing an rma yet again, but when I called back today and talked to someone else, he told me that esata only works under vista in AHCI mode. He said that it won’t work under XP in IDE or AHCI mode.
Hope someone can help me!!

Thanks for the reply.

Have you tried to install the RAID controller driver using F6 option by using the XP installation disc?
I did that when I installed XP.
Someone provided this link to set up AHCI mode. Plan to try that in the next day or two.

Funny, people should read first.
Running them on 1066MHz instead of 800MHz will get you little to none extra speed.
The only thing you'll get is the possibilty of an unstable system and maybe a 2 second win.
Furthermore, it will only be noticeable in benching, in real life you will not know the differ between 800MHz and 1066MHz.
Just my thoughts on the "1066MHz memory issue", which alot of peeps have lately.

Thermalright HR-03 GT clearance in the P7N Diamond

http://pws.prserv.net/tpham/P1000366.jpg
Anybody try this on the P7N Diamond? See, it's overclocking related cuz you're overclocking the video card. Close enough. I think the northbridge fan thingy might get in the way, but you can bend the northbridge thingy though. At least I did. It wasn't straight when I first got it so I bent it straight. I don't know. Anyone try the dual Thermalright HR-03 GTs yet? I hate to have to buy two of these things just to find out that they don't fit. No point is buying just one since you can't overclock just one of your video cards I don't think. At last not with Rivatuner I don't think.
Thanks for the info if someone has confirmation that it works.

yeah, those things are huge, but the stock coolers suck though. also I heard that heat isn't the limiting factor. it's the voltages on the GPU and ram and stuff. because people who have gotten the temperatures down to 45C at load still can't overclock 'em that high. So you gotta figure out a way to mess with the voltages on the cards themselves. I don't know if you can actually do that. I can't imagine the "BIOS" on the cards are that sophisticated.

P7N Diamond Compatibility w/ Pentium E6300 Wolfsdale

I would like to know if the P7N Diamond, Flashed to the latest 1.4 bios, is compatible with the new Pentium E6300 Wolfsdale (DualCore)?
Intel's Product Info for the E6300:

Yes see here.........
http://eu.msi.com/index.php?func=prodcpu2&prod_no=1372&maincat_no=1
Hmm... just to clarify, Intel is playing games with their CPU model numbers and has re-released "E6300" under Wolfsdale. The original "E6300" was a Conroe core and is what is listed in the official MSI P7N Diamond CPU compatibility list (both B2 and L2 stepping). Unfortunately, the Wolfsdale version isn't listed yet. However, the P7N Diamond latest BIOS does support all the prior Wolfsdale cores and the mobo generally supports 1066 FSB processors. So, although I'm not 100% certain, I'm pretty confident the E6300 Wolfsdale should work. Someone please correct me if I'm wrong, but my impression is E6300 Wolfsdale is much like an E8300 Wolfsdale but with only 2MB L2 cache instead of 6MB.
Same CPU compatibility list from MSI Global site can be found at the link below
http://www.msi.com/index.php?func=prodcpu2&prod_no=1372&maincat_no=1
For absolute certainty, perhaps you should try to contact MSI support directly or wait for a response from a user who's successfully confirmed compatibility between P7N Diamond and E6300 Wolfsdale.

Users running the P7N Diamond and QX9650 please weigh in. I need help...

OK, I'll start from the beginning. I had an EVGA 780i mobo, which ran a Q6600 at 3ghz quite easily. Well, I decided that I had money to burn so I ordered a QX9650. It would not work on the EVGA, the cpu voltage and cpu fsb voltage would not adjust no matter what I tried. So, I popped the cpu into my kids rig, which has a DFI X38 mb and the cpu worked perfectly, voltages adjusted, multiplier adjusted, etc. During the RMA process to EVGA, I got an MSI P7N Diamond to run SLI with. Stuck the cpu in it and away I went into Vista 64, all happy. I had to bump the memory voltage up to 1.95 volts, but that was it. I then decided to raise the multi from 9 to 10. I set it, warm booted and tested it in Vista. 100% stable. 2 days later, I attempted to turn my computer on. No post. I had to power off/on very quickly to get it to post, at which point I got an error message that the cpu vid had failed or there was a mismatch with the cpu to fsb ratio, hit F1 to enter setup or F2 to load defaults. I e-mailed MSI and received beta P05 and it was just downhill from there. I couldn't cold boot at all, stock settings, OC settings, voltages adjusted, it didn't matter. So back to the shipping bios. I got a new beta this morning, dated 2/18, and it was the exact same.
Issues with both beta's:
1. Cannot cold boot.
2. Logitech G15 acts erratically prior to entering Vista.
Things I have tried:
1. Raising Vcore.
2. Raising NB/SB voltages.
2. Raising FSB Terminator voltage.
Nothing helps. MSI simply told me not to OC and run at stock and that there was no problem. Is there anyone else out there that has this cpu and mb? If so, can you post your experience with it and let me know if there is something I am doing wrong or could try?

Below is the actual transcript that I had with MSI on this issue. As far as they are concerned, I don't need to change the multiplier on my QX9650. (Start reading from the bottom up for the actual order of the conversation)
Quote
MSI Tech. 02/19/2008 Then, there is no problem with the mb.
End User 02/19/2008 There doesn't seem to be any issues with usb while on using the shipping bios, I only see it when I flash to the beta bios'.
MSI Tech. 02/19/2008 If the stock bios also has the usb issue then try: Have all USB device connected to the rear USB ports that are build onto the mb and retest with all USB header on the mb be removed from any front USB connections or adapter connections and retest. If all steps have been tried and problem still persists then please kindly refer to our website for manufacturer warranty RMA info/request: http://www.msicomputer.com/support/CustomerS.asp
End User 02/19/2008 No change. I cannot even cold-boot at stock settings with this. Also, it still kills my Logitech G15 keyboard randomly. i have to unplug it and plug it back in to get it to power up, and that is only after I boot into Vista. Back on the shipping bios for now at stock settings. Please, if you would, keep me informed of changes or progress. Thanks.
End User 02/19/2008 Thanks! I will poat back if it helps or not.
MSI Tech. 02/19/2008 Beta bios v111 attached to this form.
End User 02/19/2008 Is there any other beta bios' that you have that could help? The P05 didn't work out so well, maybe you have a newer one that I could try? It seems odd that it is only on a cold boot that I have issues and not on warm boots. I am willing to try anything you got at this point!
MSI Tech. 02/19/2008 Sorry, but MSI did not see any issue with using QX9650 processor.
End User 02/19/2008 So are you saying that as far as MSI is concerned, there is no issue with the QX9650 and the P7N Diamond motherboard? I am not asking you for advice on hot to OC it, I am asking you if you know of the issue and are looking into it to try and correct it. If you do not think there is an issue and are not going to investigate it, then I will be very disappointed.
MSI Tech. 02/19/2008 If there is no problem with standard bios and no OC then you can refer to other website/forum for OC suggestions or settings. MSI does not provide these setting/suggestions since it can cause damage to the components.
End User 02/19/2008 Also, I am unable to use the Dual Core center, as I am running Vista 64. It does not load properly when using this OS.
End User 02/19/2008 As of now, it boots and runs fine with the shipping bios and no OC. But, why would I have paid such a high premium to get a QX9650, that has an unlocked multiplier, if I cannot use it? Is this strictly an issue with the newer 45nm Intel processors or is it something else? If not being able to use my cpu's unlocked multiplier is "ok", then I may return the board for a refund.
MSI Tech. 02/18/2008 What is the problem when system uses the standard bios and not OC?
End User 02/18/2008 Is there a fix on the way or is it just a problem with my hardware? I have it back on the shipping bios and it is at least cold-booting now, as well as my G15 is working. I upped the NB voltage a hair above auto, maybe this has somethinng to do with it?
MSI Tech. 02/18/2008 Use the standard bios and use software to OC: http://global.msi.com.tw/index.php?func=downloaddetail&type=utility&maincat_no=1&prod_no=1372
End User 02/18/2008 I was way too quick to say everything is OK. I now have cold boot issues aplenty. 9 times out of 10 it will not post on a cold boot, but will warm boot. I have to power off then on real quickly to get it to post at stock speeds. Also, my Logitech G15 started to act erratic with the P05 beta. I am back on the shipping bios until I hear from you.
End User 02/18/2008 Thanks you for the beta. I flashed to it, cleared the cmos and set everything back up and now I have a new problem. Even though I have disabled the EIST function in the bios, it still seems to be on. i am using cpu-z version 1.44.1 to monitor the multiplier and it randomly shifts between whatever I set it to and 6. It is even doing it when the system is loaded, ie playing games. Please, help!
MSI Tech. 02/18/2008 Beta bios attached to this form.
End User 02/18/2008 Everything is stable 100%. But, on my QX9650, I set the multiplier to 10X to run at 10x333=3.33ghz. It was fine until this morning. I turned the computer on and it would not post. I powered down and repowered it up and it siad the cpu vid had failed or errored, hit F1 to enter setup or F2 to load defaults. I entered setup and the multiplier was set back to 9x. I left it there and am ok now. Is there a beta bios that helps out operations with the newest Intel 45nm processors, such as the QX9650?
I have absolutely no issues in Vista itself, it is 100% stable. It is only on a cold boot that I have serious issues. And yes, I got 3 in a row, went to work for a few hours, then came home and bam! No cold boot. Also, I don't know how comfortable I am raising the vcore that much, as 1.21-1.25 is the normal operating range. 1.3625 is aweful high. Now, with the 65nm quads, that is more in the range of what would be needed, but no way should it be necessary to pushh this QX9650 to a meeger 3.33ghz. As far as temps go, I have the processor watercooled, so no worries there. I am away from home now until Saturday morning, so I can't test anything until the weekend.
Thanks alot for the responses!

MSI P7N Diamond - New PC Build - Need Help Posting

I just finished connecting my P7N Diamond out of the case and powered on my new build for the first time and saw BIOS version, HDD information, and the bad checksum message on the screen. I also saw the "Press DEL to enter BIOS" and the "F2 To Continue" messages.
Pressing the DEL key on the keyboard resulted in nothing happening at all. I soon realized that the keyboard wasn't responding and I had no num lock light at all after pressing the Num Lock key multiple times. I started with a generic, USB keyboard and then swapped keyboards to an older, still working one I had with a PS/2 connector.
Still no keyboard lights but magically it entered BIOS after I plugged it in the PS/2 socket and immediately asked if I wanted to exit BIOS without saving. Pressing the "Y" key did nothing. Pressing <ESC> did nothing. The keyboard seemed frozen.
I pressed the RESET button on the motherboard and this caused a re-boot but now with a black screen (no messages at all). I powered it down, removed the power cords and then pressed the "clear CMOS" button. Re-connected the power cords and powered it on; but still a black screen. Powered it down, removed the power cords and removed the battery for 1 minute (I even pressed the clear CMOS button again). Re-connected the power cords, powered it up and still have a black screen.
I know this is the place where all the experts hang out, so any help will be appreciated.

Just an update...
New build is working very well at this point.
I've set the voltage in BIOS to 2.1 for the memory and installed Vista Ultimate, updated it via Windows Update site, applied the memory patch. I've discovered that I have a bad stick of memory as no matter what slot I place this one stick of memory in, the PC fails to post, so I'm running with 3x1GB sticks. I've ordered new memory that should be here today; Corsair TWIN2X4096-6400C5DHX.
The only problem I've encountered thus far is with one of my NVIDIA RAID arrays in "Degraded" status (mirror broken). This happened after I had applied the latest MS patches and a re-boot. I didn't suspect a HDD failure because the drives are new and the status of each drive was displaying as HEALTHY. I did my research on this site and discovered the solution which was to delete one of the two drives (I chose the one with the least amount of data) from the array and then added it back into the same array. The re-build took about 2 hours (they are 400GB Segate drives) and now it's working as advertised. I suspect a software problem caused this as one of the two drives was showing that it had less data (used) than the other drive.
My next steps are to install the new memory, test it with memtest86+ and then begin the OC ritual.
Thanks again for your help, Jason and Aaron Yuri.

P7N Diamond, unable to access RAID Config during Boot

I've got a P7N Diamond motherboard, with 6 disks attached, one SSD (boot) and I recently installed 5 1.5TB disks as well. These I would like to run in RAID 5 mode. I've enabled RAID for those channels in the BIOS, but I am unable to access the RAID config that's supposed to be available during bootup. The system also has an ADAPTEC RAID 1430SA ROHS SINGLE PCI-E LP 4-PORT controller with two disks attached, could this be messing things up? (I DO get an option to access this RAID config, but it fails claiming too little free memory (!) (It's a system with 4GB installed)) In Windows 7, the 5 disks shows up in the NV Raid as "Free disks", but I'm not able to do anything with them except setting SMART info. In the Windows Disk management they don't show up at all.
So, anyone got any ideas on how to access the raid config (F10) during boot?
All suggestions appreciated
Thanks,
Zem

The error regarding "too little free memory" isn't related to system RAM but to bios ROM address space. As already stated, the Adaptec card is causing the conflict with the NV RAID controller bios. This is actually a very common issue when trying to run multiple disk controllers in a single system and isn't any fault of the mobo. There's only so much addressable space for BIOS to reside in.
You may be able to free up some address space by disabling the LAN Option (boot) ROM in CMOS and setting the JMicron controller to IDE instead of RAID. Even better would be to disable the JMicron controller entirely.
If, after doing so, the Adaptec controller is still not able to work with the NV controller in RAID mode, then I'm afraid you're out of luck.

P7N Diamond, need help

Hello, i have built a new machine and now after a few days i think my graphic card died. Computer starts with gpu fan at 100% but thats about it, screen is blank.
Havent tried to switch graphic card yet, gonna buy a cheap one tomorrow, i suspect the psu but it should be ok, hmm =)
Anyway my system, i hope any of you can help me out.

I am not very good at explaining in english but the psu should be high quality and was best rated by a swedish oc site.
Before i bought this i read alot on different sites to find out if i needed 26A on one rail or not and some said it was needed and some said
it works great with just a high quality psu.
I have also tried to remove everything except the graphic card, cpu, memory, and tried it with only 1 stick.

I solved it, thanks for the replies. Dont know what was causing it, i removed the motherboard from the case and it worked.
But there are still some issues, but i dont know what =) I have tried to overlock also but it isnt going very well, i dont know why its failing if it is the memory or if i dont give enough voltage... i made it boot at 4 ghz and the stress test with Orthos failed when memory was involved 8(
The thing i dont get is if i choose manual and set the ram memory at 800 mhz, does it stay there when i pick a higher fsb or does it secretly overclock =)
Also everytime i boot up vista 64, just before the login screen appears, when things work it fades nice to the login screen but when something is wrong it looks like a sick sack or how its spelled, pattern in black before the screen appears, even if i dont overclock at all.
Does any of you know what voltages that i should stick with? I would like to have the whole bios at manual but i dont know what most of the commands do, like the terminator, gtl settings =)

Re: P7N Diamond standby problems

I too have a very similar problem and it's driving me nuts! Although I've been all over this site reading similar posts (and all over the web), I see no-one offering any solution. :(
Like MrMicrochip, my system goes happily into S3 standby mode but when when trying to resume (keyboard or power button), it powers on briefly with all fans running and 5 seconds later just dies. Nothing posts on the screen and the only way to get the machine running is to power the whole thing off and re-boot as normal. Reset or the power button has no effect.
I've tried all of the applicable BIOS settings with exactly the same results.
I've updated everything I can think of to the latest version - BIOS, Win XP service pack 3, NVIDA drivers (180.48), and tried various settings in Windows.
My System

If anyone can help out I'd be very grateful. S3 standby will be really, really helpful with the way I work.
Thanks

cheers, i think we got it, the malfunction is due to USB keyboard and the USB terminals and nothing else,, generally even your mob supports usb keyboard but believe me a lot of guys have found that it does not function fully and usb keyboard fail in many ways, and if you look most manufacturers still Kipp ps2 keyboard terminal even so they are suppose to be out of date but because they have proved to be more reliable than usb keyboard. so your short solution is try ps2 keyboard (i myself do not use usb for this reason) but having looked at your PC config, you have three hdd 500gb and 4 memory sticks, and most likely dvdrom, floppy,..etc. and 1kw psu . but a Lot of mob power distribution is poorly designed and also psu power distribution is poor too, a lot of power has been devoted to hdd and dvd etc and mob ignored then put these two together we may end up in a situation like this.
Solutions:
1-assuming you got the latest bios ,
2- assuming the terminal molex power supply connector to your CPU is 8 then it must be 8 and not 4, if your psu has only 4 then you must use another molex 4 pin connector
A-use ps2 keyboard
B-use usb keyboard but try to remove one or two hdd and see if stand by functions or not (most likely these are the culprits, they draw too much power from psu)
C-use PCI usb card and then connect your usb keyboard to the pci usb card. there is more power in terms of voltage and current stability in pci terminals than anywhere else.
D-update the driver for your usb keyboard using device manager
and the final solution which might hurt your pride send the mob back to msi and ask for a refund

OC on a P7N Diamond with a Q6600

Intel Core 2 Duo Quad Q6600
P7N Diamond
Roseweii 850W PSU
NVIDIA GeForce 9800 GTX
OCZ 4GB DDR2 800MHz (PC2-8500)
Windows Vista 32-bit
Been having trouble with system stability, computer restarting 10min to 3 hours into gameplay, and discovered a lot of other people with the same CPU and MB as I do with the same problem until they OC the CPU to 3.0 MHz. Question is how do I OC the CPU to 3.0 GHz? I get the FSB to 1150 MHz but any higher and the computer powers up like normal but the monitor remains in sleep mode as if the video card has gone out and I have to yank the CMOS battery to get a screen to come back up. Are there other settings I am missing to push the OC up to around 1333 MHz (about the speed for 3.0 GHz)?

Well i dropped the multiplier to 6 and went for 400fsb but it wouldnt do it even at 1.4 on the nb
after a few dozen combinations i managed to get it 10 round ibt stable at 412fsb with fsb term on 1.210 and gtl down 1 notch (hit minus button once from auto - 0.7something) and nb at 1.425
CPU volts didnt factor as it was running below stock speeds
i tried lowering the nb volts to 1.4 but it failed ibt so seems those settings are it if i want 412 fsb
*sigh* doesnt look like these 780i mobos will ever reach 450 fsb :(

Frequent lock ups of my P7N Diamond

Here are my system specs:
Intel Core2 Quad Q9300 @2.50Ghz
P7N Diamond
Nvidia GeForce 9800GTX
Creative X-fi Xtreme Audio(came with board)
Hyundai Electronics Zion DDR2 800Mhz 2GB(1GBx2sticks)
Corsair CMPSU-620HX PSU (620W)
Segate Barracuda 500GB hard drive
Windows Vista 32bit
The problem is My computer restarts anywhere from 5min to 2 hours while playing a game and sometimes even while just browsing the internet and watchin videos.I ran
memtest and sticks are perfectly fine.I have the latest video drivers(185.20) and other necessary drivers are also installed.Disabled all unnecessary items in BIOS on the motherboard
like spread spectrum,eist etc and since i came to know from other threads about the video corruption issue,i updated the bios to 1.2B1 still the problem persists.the system is completely unpredictable as it simply locksup with the audio goin into an infinite loop with the video still.I hav everything running at stock speeds includin CPU,NB,DRAM all set to auto.
My memory timings are 5-5-5-18 with command rate 2T at 1.8V.CPU,system and GPU temperatures are normal.Please help me as i am not able to hav a stable system.Suggest any remedies for this issue.
thanks

ok i will up the CPU and NB voltages as u specified and lets hope its the end of this problem and i hav disabled the spread spectrum in the bios before only..
well as per the CPU-Z here are the list
From SPD tab
Timings table
Frequency: 200MHz 266MHz 400MHz
CAS#Latency: 3.0 4.0 5.0
RAS# to CAS# 3 4 5
RAS# Precharge: 3 4 5
tRAS: 9 12 18
tRC: 12 16 23
Command Rate: 2T 2T 2T
Voltage: 1.8V 1.8V 1.8V
And from the memory tab
Current timings:
DRAM Frequency: 400MHz
FSB:DRAM : 5:6
CAS#Latency(CL): 5.0 clocks
RAS# to CAS# Delay(tRCD): 5 clocks
RAS# Precharge(tRP): 5 clocks
Cycle time(tRAS): 18 clocks
Bank Cycle Time(tRC): 23 clocks
Command(CR): 2T
Wat is the next step??
thanks
PS:Can u tell what u voltages u hav set for the CPU and NB in ur board for now??

P7n diamond - no bios - 2 of them - fun troubleshooter

Hello,
I write fun troubleshooter because I went so far as to try my friends "working for years" Asus P5B-Plus mobo and CPU and RAM and had same results...
Specs: P7n Diamond - OCZ GameXstream 700W PSU - E8400 Wolfdale - G.Skill 4gb RAM (2x2) - MSI NX8800GT 512mb OC - 2 Sata WD HDDs - 2 Sata DVD drives
The Story:
I get my supplies from newegg and built it, it turns on (gives CMOS Checksum Error) but then enters bios..... then I get random freeze-ups (even in bios) that were fixed by manually setting my ram to its default timings and low end of voltage. This fixes it enough to allow me to install Vista 64 business. I get everything running happily and play HL2/TF2 games for about a week before it starts locking up more and more frequently. my USB mouse would die in game and the mouse lights/laser would turn off before the system just froze about 10 secs later... So I decide it could be a Vista issue and so I setup a dual-boot with XP-32. It seems to fix the freeze-ups before about 5 days later it starts freezing in XP too. I ran memtest for 6+ hours with zero errors (albeit it did give me memtest errors when i used bios auto timings for ram)... During the freeze-up issues I went from bios 1.0 to 1.16 to rule that out..... didnt fix it. It ended up getting to the point where I was freezing before windows XP or Vista even loaded... so I RMA'd the p7n diamond.
Receive my 2nd p7n diamond and got it in.. It boots to Vista before freezing 2min later.. same with XP.. mouse stopped working after even just surfing IE. then it hard locks... one time I did get the (PFN_LIST_CORUPT) BSOD... but its not consistent.. most freeze-ups just hard lock it with no BSOD. I get immediately frustrated and try throwing my friends 4 (1gb) sticks of PNY DDR2-667 in the machine... turn it on and it doesnt boot to bios at all/nor give any beep codes.. re-throw my DDR2-800 back in and again.. not even an attempt to show bios - i turn it on and nothing comes up on the monitor (the monitor just flashes waiting for a signal).. So I try more troubleshooting. Disconnected EVERYTHING but one stick of ram and the graphics card... same result - no post.... swapped ram, even tried taking the graphics card out.. no beep codes... I then assume its a bad CPU and try my friends working-for-years E6300 core-duo chip.... same result-no bios..
Then I figure - it has to be 2 bad p7n diamond mobos.. So i try my friends Asus P5b-Plus with my E8400 CPU... turn it on.. SAME result!! no bios or beep codes.. i'm thinking now bad PSU and its frying Mobos on contact?? Odd because both p7n diamonds gave me perfect on-board LED readouts when plugged in and turned on (and on standby).. All peripheral cards lit-up fine... and my friends p5b-plus also had the red light showing it was getting power.... Is it possible a PSU that worked for 2 weeks relative fine all of a sudden fry things?
so I go to best buy and buy an Antec 650W PSU to rule it out.. same result! no bios...... the main frustration is I was using the system for about 2 weeks relatively fine and now all of a sudden things seem to "fry" on contact..
Anyway, I RMA'd this p7n diamond, and the OCZ 700W PSU to try new ones... I was just looking for opinions on what could be the problem.. I mean as it looks.. either the PSU was frying motherboards yet still lights their LEDs up.. or my E8400 CPU is ruining the motherboard?? or my RAM went bad after being OK?
some questions - when I get my new setup - im going to plug it in paranoidly...... Can I power up the system with no RAM sticks in it at all?? I just want to make sure RAM wasnt causing the mobo to short out? Is it possible the GPU is frying the mobo? Could my Antec 900 case wires be causing this? I feel since I tried so many diff combinations its the one thing thats staying consistent??
Thanks in advance!!

Mike...when you get it back...run it outside the case, just the bare essentials, lay the MB on a non-conductive surface (the foam packing works fine.) If it boots up and works normally..start checking your case for extra MB standoff pins that you may have left in..they will short the board. If it still has a problem out of the case w/ minimum components...then you can start troubleshooting components. This is the way to start. G/luck.
Paul.
