P7N PLATINUM SLI dont post at all!!!!!!!!!

i bought a new msi mobo p7n platinum sli, after backing it in the case and connecting everything,it doesnt post,and it freeze on the msi logo..
also the keyboard dont work at all, so i cant enter the bios,if ipress on del it gave me a black screen write in it as follows:
A7380NMS V1.0 011508....
system specs are:
1. MSI P7N PLATINUM SLI
2. CPU INTEL E7400 2.8 GHZ
3. 2x2GB KINGSTON DDR2 RAM
4. XFX NVIDIA 9500 GT 1GB
5. GIGABYTE PSU 550W
CAN YOU PLEASE PROVIDE ME WITH THE SOLUTION,ITS A BRAND NEW PC
THANK YOU ALL FOR THIS GREAT FORUM.....

Remove mainboard from case and try running with just absolutely necessary components. Try reseating cpu and check if heatsink has proper contact to cpu's heatspreader. Try running setup with just one mem stick.
Also provide full specs of psu as you can see in my signature.
From the writing you reported (A7380NMS V1.0) it seems your board has bios V1.0 installed while your cpu would at least require V1.2 or higher (http://global.msi.com.tw/index.php?func=prodcpu2&prod_no=1373&maincat_no=1#menu).
Possibly you might need to lend an older Core2 cpu to install bios V1.2 or ask the retailer to flash it for you. First step is of course to try eliminating other possible sources for the issue as listed above.

P7N platinum sli and qx9650 overclock issues

Hey all,
Just wondering if someone could help me with overclocking my qx9650 on my P7N platinum sli.
I have tried throwing all kinds of voltages at the cpu, fsb, and nb and I still can't run stable for over a few seconds. I thought it might be due to a fsb hole and have tried a range from 1550-1650. My goal is to get it at 400mhz(1600 in bios) and get a 5:4 ratio with my ram at 1000. I tried updating to the p06 performance bios from ami 1.3 and still can't get it stable. I don't want to end up frying my board. I got it to run stable at 350 for an hour in prime 95 but would really like to achieve 1600. at 350x8.5 for 1500 my temps did not get above 54c under full load
I am not looking for a huge oc, just get to 9x400 for a 3.6 ghz clock speed for 24/7 use. I ran prime 95 for 5 hours with everything at stock so I know it is not a bad cpu, ram, mobo. I also ran memtest86+ at stock and every test passed. I have d.o.t disabled, eist disabled, and spread spectrum disabled.
Memory timings right now are 5-5-5-18-2T at 2.1v and memtest+ passed with those settings at speed 800mhz.
any suggestions would be great

just wanted to let everyone know that i got it stable at 3.75ghz for 26 hours in prime 95. Don't know why but it still won't boot from 1550-1650 (must be a FSB hole or something) so i just put it at 1500(375) with a 10 multiplier and ram at 1000 for a 3:4 fsb:ram ratio.

MSI P7N Platinum SLI 750i freezes, even in Safe mode

I have had this board for about a year and a half. My sig should show the specs. I installed 8 gigs of G.Skill memory about 4 months ago, and everything has run great until about 3 weeks ago when I started to get random freezes. The monitor is still showing what was up, but the keyboard and mouse stop responding, as well as all other controls. I have had error logs analyzed and been told I may have a bad video driver, so I deleted it and let Win 7 install its own, and froze again. I logged into Safe Mode, it froze. I ran Memtest86+, machine froze while running it, then on reboot showed errors on the G.Skill memory, all 4 sticks. I put my old memory back in, still freezes. In fact, it sometimes freezes during the POST, when nothing but the BIOS is running.
Sometimes the machine will boot up and run for anything from 2 min to 30 min, then freeze. Sometimes, when I reboot it, it will not post at all, but just show a black screen. If I let it sit for 5 to 10 min it seems to boot again, but inevitibily freezes again. I got one error indicating a BIOS problem (BIOS checksum not equal) but only once.
I am afraid to flash the BIOS, as a freeze then will kill the board. The freezes during memtest and POST indicate a hardware problem, and having 6 memory sticks go bad (two previous ones went bad) also indicates a bad board. Running HWMonitor shows no fluctuation in voltages or any high temps, so I am baffled.
Anyone have any ideas?

You don't need to connect HDD at all.
Get Live Windows or Linux CD - one that has lots of testing utilities.
Check BIOS - frequencies/timings/voltages.
Well, the HDD is not the only problem. The only PSU available would power the MOBO, but cannot power my video card, and the board has no on-board video. I only own one PCIe card, so I am out of luck there. I did turn the machine on several times with a multi-meter connected to several 4-pin Molex connectors, and the power was correct and consistant (12.26v to 12.28v, no fluctuations over .01v during or after start up and 5.01v to 5.03v and 3.3v all the same). I know testing with the multi-meter does not show it under load, and is not the best test, but it is all I can manage.
On the Windows 7 forum, someone suggested this site http://www.badcaps.net/pages.php?vid=5
Several items here caught my attention:
Motherboard fails to POST.
Memory Test Fails.
Fails to fully boot (or even install) Operating System.
System randomly and frequently freezes.
BSoD or hard freeze under heavy drive activity (Either RAID, SCSI, or standard ATA). (This is questionable, the HD light is on, but I cannot hear it running)
Resetting the system after a freeze and the system will not repost.
(You have to completely power down then power back up.)
A physical inspection of the board shows no leaking or bulging capacitors, although a couple are not perfectly perpendicular to the board.
I am beginning to think the board is bad, and I found a good replacement on e-bay (NEW board) for only $90. It is selling rather well and with only 4 left I am inclined to get it before it disappears. This is the board:

Now i finally got a different report back from windows error reporting saying a "Non Compatable BIOS is the cause " here is the error report screeny i took and uploaded to flickr http://farm4.static.flickr.com/3538/3349882297_4a3194e3df_b.jpg and this is another screeny in flickr of my BIOS in MSI Info View http://farm4.static.flickr.com/3445/3349882397_ef282a33d2_b.jpg , i believe i have the newest BIOS installed and the correct one also and have been running that version for along time . When i first setup this system i could not get my Q9550 to boot at all with this mobo till i updated the bios to the P0B6 but have never had it stable from BSOD . My Specs are Q9550 "Core 2 Quad Yorkfield SLAWQ Q9550 333 2.83 12M " / MSI P7N Platinum 750i SLI / OCZ Vendetta CPU cooler / 4GB- 4x1GB OCZ FLEX DDR2 1150 / OCZ GameXtreme 1010W / 2x - XFX GTX260 Black Edition in SLI / 1TB Seagate HD .
Also i had just tried the live update but it says there is no new updates for bios , when i first did the update i used a 3.5 floppy and flashed the bios to the ver i currently have now because there was no way for me to use the live update with XP Pro 64bit , Now im running Xp Pro 32bit w. SP2

I suggest that you clear CMOS and use flash it to the BIOS v1.1 under the MSI website for your board and see how it goes.
http://global.msi.com.tw/index.php?func=downloaddetail&type=bios&maincat_no=1&prod_no=1373
LOL thats funny !!!!! 1.1 is what came installed on the mobo and is not compatable with the Q9550 it will never boot to bios using 1.1 with a quad core ! Thats the first problem i had thats why i explained all the steps i had to go through to get this mobo / cpu to boot with the help from MSI tech support !

**!! SOLVED !!** MSI P7N Platinum SLI Stuck on Splash Screen

Okay, so I got a bunch of new hardware for Christmas and finally the rest for my birthday this weekend and I am stumped. I got all installed and when booting, I get the MSI splash screen with the spaceship and nothing else...just stays there on the splash. Only one beep like my other MSI boarded PC and no more after that. I have tried reseating all components including CPU, ram, graphics card and still no luck. Also have tried with mainboard out of case on the box with all connectors plugged in. My hardware is as follows:
MSI P7N Platinum mainboard
Intel E8400 Wolfdale
Corsair DDR2 2 x 1gb
nVidia PCI-E 260 fx card
I have all else unplugged to eliminate as much as possible. PLEASE help me salvage this because I have to say its been the most disappointing birthday ever this year LOL. Thanks guys!!!!
P.S. Also tried reseting CMOS many times including overnight unplugged and mainboard battery removed.

OK everyone...problem is fixed. As u all thought, the S-Spec of my CPU was not supported my the BIOS version (1.1) that the Mainboard P7N comes with...so the way I remedied the situation was to find (and purchase) a cpu that is on the cpu support page for mainboard that is supported by bios version 1.1. I also must note, do not go by just the model number, go only by S-Spec number. Once my Intel Celeron D 3.3 came today, started pc with a botable floppy (made by windows on my other machine) and flashed bios the old fashioned way with floppy disk. After flash to version 1.3, put my CPU back in and what do you know...IT WORKS!!! So got Windows installed and have been stable for about 6 hours now. Thanks all who contributed...I love you all!!! LOL

NVidia's nForce drivers on P7N Platinum SLI

I just wanted to query the forum and other nForce mobo users to see if they had any problems with using the nForce chipset drivers provided by nVidia on their website. I currently use the chipset drivers provided on the MSI website for the P7N Platinum mobo (750i northbridge, 430i southbridge) and they have outperformed all other drivers supplied by nVidia, including the latest 15.45 package (difference of 500-800 marks in PCMark05). Is this common on nForce boards? Are there certain parts of the nVidia drivers that don't work with the P7N, which would make MSI have to create its own driver package for the board? Anybody else have issues with nVidia's nForce drivers?

I have a P6N, the slightly older brother of your board and yes I had troubles with one of their Nforce drivers in Vista.
Like you im running the ones from MSI, somehow they do the trick much better.
They are older, but who cares
Updated it once, but had to roll back due to all sorts of troubles, so íll stick with them.
In Win 7, im running the 15.35, cause MSI has no drivers for Win 7 for my board and so far, no issues.

P7N Platinum no POST

When I set FSB to 1200 for Q6600, no POST on my mobo P7N Platinum Sli. No joy at FSB1333 too. It POST successfully with E6600, both at FSB1200 and FSB1333.
Another strange thing is no POST when RAM timing set to 1067 2.1V or 2.2V (using Team Dark-1066 3GB module x 4) even at default FSB1067. It was ok when using 1GB module. However, if I volt to 1.95V, it boots but unstable (probably due to insufficient voltage). Changing to 2V or more results in no POST.
How went wrong?

Reset everything to stock speed without any OC and see if there is any problem. If there is no problem when in stock speed, you should post your query in our Overclocker's section.

P7N Platinum Q6600 @ 3.5GHz, you to can do it

Just thought I would share my results of getting over the dreaded 3.0GHz wall. I'm still in the testing phase (running 4 prime95 at maximum heat consumption right now), it seems to be running quite strong. I can probably hit 3.6GHz or more, but that will be later.
Vcore: 1.47v total, +.2v settings
VTT: 1.5
NB: 1.5
SB: 1.5
v1.2 bios
I'm going to be scaling back all the volts to find out where the weak spot is for overclocking. I don't exactly like running the VTT and NB at 1.5v, but many people have been running their Asus 750i boards at 1.50v and doing ok. Max temps so far are 56c on cores 1 and 2, 54c on cores 3 and 4, running 4 instances prime95.

Bumped them both down another notch. I think that is 1.42 and 1.40. So two notches from the top. I'm going to be moving the cpu volts down tonight.
It looks like I almost have the same system as you:
P7N Platinum SLI v1.2 Bios - Q6600 G0
Zalman 9700 LED Cooler
Corsair XMS2 DHX PC2-6400 2 x 2GB 4-4-4-18
8800GT SLI
Enermax 500w PSU
Antec 1200 Case
WD 250GB/ Windows XP Professional SP3 x86
WD 750GB
I just recently got the 1200 case, man I love it. I don't think I can ever go back to a normal mid-tower.
The case keeps everything really cool. I'm running all case fans at low and the Zalman 9700 at 1650RPM.
My voltages are
vCore 1.496
FSB (one setting over stock)
NB 1.28
SB 1.50
Everything that can be turned off in the BIOS is off. RAM is unlinked and running at 800MHz (for now)
I'm going to go for 3.5GHz, just enjoying playing Crysis more than I enjoy run Prime95.
Regards,
Doug
BTW: I'd appreciate it if you gave me your RAM settings, and voltages.

P7n platinum - e8400 overclocking issues, pls post your settings

Dear OC experts,
I have troubles overclocking e8400 to 3.6 ghz on p7n platinum board. I have tried many variables and options in BIOS, but the problem remains the same. While doing regular tasks on my PC, everything seems to be stable, but when I start a game (battlefield 2 bad company or skyrim) the PC freezes. I have upgraded BIOS to the latest version, I have all the newest drivers, tried many different settings in the OS, but it does not help. The video card is gtx560. There are no problems/freezing when I set all the values in the cell section in bios back to default.
I have searched web alot, my eyes are red... The only remaining hope - you : )
I would greatly appreciate your help. Could you please post your bios settings for the OC'ed e8400 if you have the same board.
My systems is:
E8400, 4GB 800mhz 6400 RAM
3 HDD (total 1TB)
GTX560 1GB
Win7 64bit

P7n platinum no post after cpu change

Just built a new rig, got it up to post screen and freezes.bios is version 1.1. I have read all other posts about this particular problem for p7n platinum and tried all the recommended solutions, none avail.
Tried to flash to bios 1.2 with floppy but floppy didn't boot.
Changed to e2140 cpu, even worse, no screen whatsoever. fans, lights, etc. are running.
Reverted back to the e8400. no screen as well. Checked for bent pins and power connections, all seems fine. Before changing cpu's, it will show the post screen but freezes there.
Time to send back to the reseller?

Quote from: Jack the Newbie on 22-October-08, 01:27:42
If your system will boot up with another PSU, what would that tell you about your current one? It is either defective or incompatible. In the first case the problem can be fixed by replacing it and in the second case you'll need a better PSU. One that does not have known grounding/compatibility issues.
ok. But correct me if i am wrong, the first few times booting with the e8400, it will show the screen, doesn't that tell that the PSU is ok with the MOBO?

MSI P7N Platinum and 8800GT of 8800GTS in SLI with everest is FREEZE

Hello,
I want to warn users of the msi p7n platinum with the 750i chipset who use everest 4.50.1372 and a 8800GT or 8800GTS 512 mb (with a G92 CPU) in SLI that they can get freez problems.
I got a extra 8800GT card and go SLI but the computer got random freezes after that.
My system:
Windows xp sp2 with an Q6600 2GB pc-6400 ram, 4 hd's (2 ide, 2 sata), dvd-writer and a dvd-rom. Latest 1.2 bios.
It was very frustrated and also mailing msi support in The Netherlands didn't help (they thought it was a problem with the powersupply). The computer just got frozen with the last picture on screen and didn't respond at all (not a single error msg). Sometimes in minutes and other times in hours. Only option after that was a hard reset.
To make a very long story short (i tried every beta bios out there with every bios setting) . I sold one of the 8800GT's and bought a SLI set with 8800GTS 512mb in the hope the problem was with the different brands of cards (EVGA and TWINTECH with the 8800GT's). But the problem was even worse with the 8800GTS 512mb G92 (from Point of View). So i take a look at the software and found out that the problem was with the everest monitor software that displays all kinds of info on my G15 keyboard. After i disabled everest i had not a single lockup anymore.
Also the latest beta of everest that i downloaded yesterday gave the same problems!
Everest was in fact the last program i disabled cause i used that to see what the temperatures of the CPU and GPU where at the moment the computer didn't respond
Mabye more ppl have this problem and are using everest and i hope that they find this thread Dunno if the problem is also with other brands and chipsets (like the 780i or 790i)

luckyjan, thank you for your feedback on this. Interesting find.

No Post - K8N Neo4 Platinum SLI - any help would be awesome

Ok here it goes. I recently bought a K8N neo4 SLI and set everything up, hit the power button, and nothing happened. So i figured it was DOA and i sent it back. got another one, hooked it up and nothing happened. Tested the PSU and power switch on a different machine and they work fine. But with the K8N i have nothing, no fans, no lights, nada. I am a relatively experienced computer builder and haven't had this one happen to me yet. I've read every troubleshooting guide on the MSI site and i think everyone in the forums but the dang thing still won't turn on. Here the specs:
K8N Neo4 Platinum SLI
Athlon 64 3200+ 90nm
512 x 2 Geil Ultra Platinum DDR 533
Seagate SATA HD 7200 RPM 160 GB
Chaintech 6600GT
Ultra X-connect 500W with the 24-pin adapter
Got a bunch of other junk too but thats all thats hooked up now. just going for the bare minumums so i could at least get some response. Please give me some ideas of what could be causing this are maybe something dumb i forgot. I know my power suppply blows but i've seen others get it going with that and since i only have barebones hooked to it, i'd think it would go. Thanks in advance.

I had an interesting thing happen to me yesterday, that sounds exactly like your problem.
I'm looking for ways to reduce my gpu temps, so I'm playing around with case fans, round wiring, etc... One of the cables I replaced ran to one of my PCI-E cards. aparently it had a short or something in it. I spent hours trying to get my computer to start up again, I was afraid I had fryed the board....no power, no fans, tried a different power supply, etc..... One wire, well two, because it's one of those that takes two molex plugs and turns them into a Pci-e plug.
What a pain....
Chack your wires, check for a short. If you're having the same issue with a second mobo chances are it's not board related. Could be you have the srews attaching it to your case to tight and have shorted it out there.
Hope this helps.
Good luck!

K8N Neo4 Platinum SLI Sound Problem

I've recently build a system using the new K8N Neo4 Platinum SLI nForce4 board, which has the Creative SoundBlaster Live! 24bit onboard. The problem being the volume of the sound output (analogue) is extremely low. All volume controls in Windows are all set to full volume, but the sound output is still very very low. I consider myself pretty good with computers but with this problem I'm stumpted. Anybody else had this problem? Any insite would be very appricated.
Various info:
With my old SoundBlaster Live! Value the sound is fine
System Specs:
K8N Neo4 Platinum SLI
Athlon64 3500 Winchester
1gb PC3200 (Crucial ValueSelect RAM)
nVidia GeForce 6800 256mb
WindowsXP Professional w/ SP2
Any help will be appreciated

Ive been wanting to set up a new system based of this same motherboard, but all the power supplies Ive found so far have either been brands Im not familiar enough with or I havent been able to find a definitive answer on if the power supply supports that -5V pin(usually both, unfortunately). Can anyone point me in the right direction for a PSU under US$100? Any suggestions of power supplies anyone has had success with will also be greatly appreciated.
Ive spent about the past three days searching and have finally reached my wits end.
Second edit:
I double checked the diamond forum link (it gave a link not found page the first time), I did get to see what was posted there, but since most online retailers and manufacturer websites dont give the best view of the main connector, thats not alot of help. The only websites Im comfortable ordering from also do not evne carry the suggested power supplies, or any other unit by those manufacturer.
FINAL Edit (I promise...kinda):
I double checked on NewEgg (and then double checked FrozenCPU.com), and I found one from OCZ that doesnt totally blow my goal of USD100 or less out of the water. Lists a -5v supply, and is 24 pin for the motherboard:
http://www.newegg.com/app/ViewProductDesc.asp?description=17-104-155&depa=1
Same thing for 129.99 on FCPU, which is where Ill be ordering the power supply from.
I dont have any real need for the onboard adjustment dials of the more expensive series, and I really like the modular PSU design, not to mention the blue color scheme will work well in my blue-illuminated case.
Now, are there any other hurdles I need to be aware of?

P7N Platinum - cant change multi or FSB - please assist!

Well I spent all this money on a new rig, all my boards have been MSI and I have no issue. While i am a newb when dealing with the intel architecture, I still understand the concepts...
Here is my rig -
P7N plat sli
q6600 - SLACR G0
Tuniq Tower 120
Tooless case, with 2x120 fans, 1 intake, 1 outake...
850w Rosewill extreme psu w/ 120mm fan
8gig (2x4) DDR800 CL5
3870
2xseagate 7200.11 sata, 1 DVD reader
I cannot for the life of me understand this board, and the freaky things it is doing.
Ok, I can post, boot, run Ubuntu Vista 64, XP, etc. play games, no issues.
I can set my board at 9x333 and boot and prime95 (albeit at high temps, 58-63), no problems.
I dont want to do that. I want be at 7x400 for a 24/7 stable oc.
Problem is anything besides the stock setting or 9x333 will not stick. If I just change the multi, it will save the values, and I can reboot and see the values, but the mobo and all cpuid etc report 9x266 as well.
If I do like, 9x300 - nogo... Wont post, requires a reset.
Occaisonally it will post, but the values in CPUz reflect stock settings. Only twice did I it boot and the mobo report the proper speed, but after a reboot, stock settings were back.
What is the deal?
And what may I ask is D.O.T.?
Ive noticed another post or two but couldnt find any answers, please help a brother out.
edit - and the bios is fine, it saves the settings correctly, saves by boot drive settings just fine. I dont think the board is actually defective.

All other settings are stock except speedstep disabled
Have you disabled C1E-Support as well? (should be in "CPU Features", press F4 to make the option visible).

And what may I ask is D.O.T.?
D.O.T.=Dynamic Overclocking Technology
Basically, it is on-demand overclocking. The system will automatically overclock itself to a certain extent as soon as there is a reason (system at full load). Keep DOT disabled when you are manually overclocking your system .

MSI K8N Neo4 Platinum SLI sound needs -5V; newest Antec 550W has no -5V rail

I came within a whisker of ordering a non-returnable 3700 Venice, MSI K8N Neo4 Platinum SLI mobo and an upgraded Power Supply, Antec's newest 550W PS the TP2-550 EPS12V ($117). This has dual 2x24pin 12V 19A rails and is touted as the new V2.0 EPS12V/ATX12v compatible power supply for high performance SLI systems. By accident I came across a page at MSI for this mobo
http://www.msi.com.tw/program/products/mai...ail.php?UID=641
At the end is this warning: MSI Reminds You...
• For this model, you must use a Power Supply which has a -5V pin supply. Also, the users manual which I downloaded on Pg 2-10 says the same thing
The above Antec PS specs do not show a -5V rail, nor does an Enermax 600W I looked at. The V2.0 specs for ATX12v which added 2x24pin 12V rails dropped -5V rail from the spec and it appears MSI is not conforming to the spec (See Antec response at end) None of the web sites selling these PS & mobos contain any warning. I vaguely recall from a forum a while back it may have something to do with the Soundblaster system in the mobo.
http://www.antec.com/us/productDetails.php?ProdID=22551 (click specifications)
Isn't this a major showstopper which is going to cause a lot of grief for those of us upgrading to SLI systems using this mobo and upgrading our PS to the newest & best power design? We won't know the PS won't work until we build the system.
Regards, Ron
Antec reply to me:
>>>>Thanks for the link. Since MSI's website does state the motherboard needs the -5v, the True550EPS12V will not work with this motherboard. The Standard (http://enhanceusa.com/documents/atx12v_v2.01.pdf) has removed the use for the -5v rail and it is no longer needed. MSI has not manufactured that motherboard to the Standard. Finding an ATX12V v2.0 power supply with the -5v might be hard to find. You should contact MSI for a compatibility list of power supplys that were tested to work with the K8N SLI Platinum.

Wow!! syar2003 thanks for that post. I've spend an hour going through it & fasteddies links. Now I are a power expert. The dual rail argument is enough for me to go back to the MSI K8N Neo4 Platinum SLI with one of the single rail PS -5V units listed by fasteddie. The only question left now refers to computerpro3 recommendation on ultra power supplies for SLI
>>I quite simply wouldn't dream of putting anything else in my machine. Keep in mind, this section is for 2x 6800 models, not the 6600's which most any good psu will handle (like Antec Neopower, ocz 520, etc). . Pc Power and Cooling 510 Deluxe SLI edition (refer to list)
2. Zippy/Emacs 550-700w models
3. OCZ 600w (personally I would get the pcp&c for the price, but it's been proven here, so I'll be fair...).
These are really high end, expensive and only 3-4 choices. Since I'm getting one 6800GT and eventually another & possibly eventually a 4800 X2, I was hoping the OCZ 520W would do it but computerpro3 says Powermaster 520 isn't good enough for SLI. I found that there is an OCZ 600W ATX12 dual rail which surprisingly has a -5V rail needed for K8N Neo4 SLI Soundblaster. Will this meet computerpro3's preference for a high end PS for SLI systems even though I'm losing the 1 rail advantage. Maybe the 600 Watts just overwhelms the 1 rail/2 rail question.
Thanks again for the teriffic help

Wondering what you settled on. I got the Antec TP550 and it's flawless on the board. I even have the older 20pin model which works perfectly (including sound). If you really wanted what I would consider to be a top dog (pcpower and cooling), and find the -5v rail missing, all you have to do is place a phone order and request they add a -5v rail. It's a minimal cost and a total solution for having everything. Just my $0.02

P7N PLATINUM SLI dont post at all!!!!!!!!!
