K9N2 SLI Plat Overheating

First, I consider myself a novice when it comes to inner workings (BIOS, voltages and such), so I probably should not have tried to build a box from a barebones kit. Now that I am in that situation - problems are arising!
my specs:
K9n2 SLI Platinum nForce 750a
BIOS v 3.4
AMD Phenom X4 9500 4M 95W Socket AM2 CPU (CP1-AM2-9500 )
Ultra LSP550 550w Power Supply
HITACHI 1TB SERIAL ATA HD 7200/16MB/SATA-3G
Ultra XBlaster Mid-Tower Case Black
OCZ Blade PC6400 800MHz 8GB DDR2
Vista Home 64-bit
No floppy drive
EVGA GeForce 9400 GT 1GB PCIe - not installed yet
Everything was going great for about a week, but earlier today I installed the newer NVIDIA drivers v15.25 (I believe). Everything worked normal for several hours, but then I noticed that the CPU temps were skyrocketing from 37C to nearly 80C in just a few short minutes. I opened the case and ensured that the heatsink and fan were working properly, and all looked good. I went into the BIOS settings and looked through the hardware monitor and noticed that the temps were still rapidly rising and that the voltage was unstable bouncing around 1.6 to 1.7. I think that is the problem and the CPU fan is running about 1600 RPM, which may be normal, not sure. I looked at the Cell Menu and it said the CPU voltage was on auto.
So far I tried to Load Optimal Settings and Load Fail Safe Settings, both to no avail - temps are still skyrocketing within a matter of minutes. Only other change I made this week was buying a new heatsink and fan ('up'grade from the one that came with the CPU - to a Thermaltake TR2-R1. Again, the heatsink has been installed for several days, and have had no problems with overheating until tonight. Oh, yeah, and I do have 2 120mm fans, one front and one rear and the MB temp has been pretty steady at about 24 to 28 C.
Is there any hope?

Yeah, I definitely took the plastic off, and the heatsink material was already applied. I suppose I put it on wrong, but there seems to really only be one way to put it on - over the clips and tighten...
Interstingly, after letting it sit overnight and rebooting this morning - it is holding steady again at around 38C (in fact, I'm using it now). The voltage at boot up read 1.55 instead of auto today, so I quickly adjusted it down to 1.3 to see if I could keep it from going out of control again -so far, so good. It is just a mystery as to why it (bios) is changing so frequently without me making any adjustments to it. I've read here and other places that there are possibly issues with this board and earlier bios versions. It came with v3.4, and I have never tried to flash to anything else. Should I try and re-install the heatsink? or does it sound more like a bios problem?

K9N2 SLI Plat AM Bios

I think I'm having a problem with the BIOS settings. When I plug two DVD burners into SATA ports 5 & 6 they are not seen by the OS. Is there a BIOS setting I need to change to fix this?

So I enabled AHCI mode made a registry change to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci was set to 0. set BIOS to AHCI and rebooted twice I move my two CDs to to sata 3 4. I connected my two secondary hard drives to on SATA 5 & 6. Know I cannot see my two hard drives. You saying SATA 5&6 are useless unless your are running RAID drives?

K9N2 SLI Plat and 630 Propus

My wife just bought the 630 for me (early Christmas) and I was wondering if anyone has tried it in the K9N2 SLI Plat. I see the 600e and the 605e, but not the 620 or 630. Do I now need to get another mobo? Any thoughts? Thanks for the help.

Re seat the CPU and make sure its properly installed, also remove power cord from the PSU and do >>Clear CMOS Guide<< then retry

K9N2 SLI Plat. showing 2 HD Audio's in device manager

Installed Windows MCE 2005 w/SP3 and everything up to date driver wise. Problem is HD Audio device is showing up twice in device manager. One shows installed, one shows that no drivers are loaded. I have uninstalled the device and uninstalled the drivers, and reloaded everything. Used drivers from CD and from download, but not luck. Any ideas on what could cause 2 of the same audio devices to show up and only one to actually load, besides a general hardware failure on the motherboard?

That would make sense, if either the 9800GT or the K9N2 had and HDMI port. Sorry guys that's a no go. This is the first time I have ever run into this issue. 2 of the same audio devices showing up in device manager. One has drivers and loads, other shows unknown HD audio device and will not install drivers at all....

K9N2 SLI Plat MS7374 Plat - Setup Raid 1 on SATA 5 & 6 Ports

Hello again,
It has been quite some since I was on the board, but you really helped me out last time.
I have 2 Seagate 500GB 2.5" drives I would like to setup a Raid 1 configuration on SATA 5 & 6. Currently one is my boot drive (SATA 1) and the other drive (SATA 2) has not been partitioned or formated. I say this because, Diskpart can see both drives but Disk Manager cannot see the new drive on SATA 2. I am guessing I will have to partition it and make it a primary & active partition then NTFS format the second drive.
I am not understanding the manual that came with my board. I have never set up a raid configuration before. Can I get a blow by blow or pointed to a good manual on how to get this done? At what point do I move the drives to the SATA 5 & 6 ports?
Thanks so much!

K9N2 SLI PLAT 1 vid card for PhysX only make both cards run at 8x?

Hi all. I'm on the fence here as to what to buy. My current setup is (hopefully) displayed
in my signature.
Here is my concern as copied from the K9N2 Sli Platinum Manual:
"• 1 mazarine PCI Express x16 slot with x16 operation (PCI Express Bus SPEC V2.0 compliant)
• 1 light-blue PCI Express x16 slot with x8 operation (PCI Express Bus SPEC V2.0 compliant)
• When 2 PCI Express x16 slots are all installed, the PCIE x 16 lanes will auto arrange form x16/ x0 to x8/ x8. Do not use the light-blue slot when only one PCI Express x16 card is installed."
Is this normal for most SLI mainboards? I was thinking of upgrading in one of two ways:
1) Just purchase a 9600GT for PhysX only and pop it in the other PCIE 16x slot
OR
2) Go all out and buy another GTX 260 Core216 SC card, new Power Supply, and new PCIE Sound Card
and SLI the 2 cards together.
With option 1, will my GTX 260 get slowed to 8x ?? That may defeat my whole purpose for getting
another vid card and dedicate it for PhysX; would it slow the main card down enough to impact it greatly?
With Option 2, the reason for a new sound card is a second "2 slot" vid card means I'll only be able to use
one of the 2 PCI slots. Currently, I have a Fax Modem and a SB Audigy SE in them.
I use the modem on a regular basis to send/receive faxes, so I will have to replace the sound card.
Anybody know if a Creative Labs SB X-FI Titanium PCIe can fit in the 1x slot between 2 SLI'd Vid cards?
The 1x PCIE slot on this board is between the 2 16x slots, not the ideal spot I fear.
If it won't fit between, my ONLY other choice would be to use the on board sound, which I am
not fond of doing.
My whole intention here is to play Cryostasis better than it does now, AND hopefully be ready
for any newer games that incorporate PhysX. As it is now, I got Cryostasis free when I bought
my new vid card, nice of eVGA to do that
If I do this, I want it to be pretty future proof:
I don't want to make EITHER investment solely for one game only. I'd prefer to
go with option 2, but I REALLY don't want to find out AFTER I buy everything that
I can't fit the new sound card between the 2 SLI'd cards :(
Any help on this will be GREATLY appreciated,
thank you.

K9N2 Sli Plat - HDD detection problem

[Split off from https://forum-en.msi.com/index.php?topic=127332.0, please don't hijack other topics! - Stu]
You are not alone..... I'm having simular issues
I flashed my bios hoping to fix the HD detection for installing windows.
now I get nothing detected in the bios. as SATA drives. IDE channels detect.
Ihave flashed the bios both ways USB and CD bootable image.
I get a NVIDIA HDCP: ROM HOLE 2 PROTECTED!
During the flash. Is that supposed to happen? everything else looks good during the flash. However now I can't even get drivers to see the SATA drives. I've tried 2 different makers.
BIOS is set to IDE on the SATA.
Note Same MB as original thread starter. 8GB OCZ memory, hitachi 1TB HD, 160 GB Maxtor HD.

K9N2 SLI Plat CPU support

I have been trying to access the cpu support list and it keeps timing out. Curious if anyone else is having problems. Is this info available any where else? Thanks.

From googling; the comments to the right may be useful reading:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813130161
OK someone got it to work, but had to adjust the VCORE before using it, I consider something official when I don't have to do that, there are a lot of users out there that don't overclock, I'm one of them, I know how and I've overclocked this 7750 to 3.4GHz stable with stock cooling, but I'm happy with 2.7GHz stock for now. I'll be upgrading to the the 980a - G65 soon anyway, not going to blow money on a 955 now, will wait til both the board and CPU come down in price.

MOVED: How to adjust CPU NB Multi, or HTT Multi in BIOS on K9N2 SLI Platinum?

This topic has been moved to Overclockers & Modding Corner.
https://forum-en.msi.com/index.php?topic=126239.0

Ok so that setting allows me to adjust the HT Link.... though it does this by multiples of 200... starting at 200; going up as high as 3000+
However I discovered that I can only go up to 1800. If I try to set it at 2000, then my system refuses to POST and I have to clear the CMOS and start over.
I also discovered that, changing this setting, does not seem to have any effect on the CPU-NB setting.
What does have an effect on the North Bridge; is changing the CPU FSB Frequency. However, not only does this adjust the North Bridge mhz, it also overclocks both the CPU and the DRAM frequency at the same time; but I can't get the North Bridge any higher then 2370mhz without again, causing the system to refuse to POST and resulting in me having to reset the CMOS and starting over.
The reason I was asking and trying to do this is; I was told by OCZ, if I can adjust my DRAM to around 1000mhz, and the NB to 2400mhz, then my ram, which refuses to run at 1066 without crashing my system; I was told my RAM would be preforming equivolent or better then 1333 ram. But it seems my K9N2 SLI Plat will not achieve that 2400 without becoming unstable.
The highest I can get it is 2370...

have you tried uping the voltage, the black dragon works perfect at 1066 from 2.2v to 2.4v, however the gskill requires 2.3v to work perfect at 1066 (so my setup its 2x1gb geil and 2x1gb gskill (total 4gb) voltage set to 2.3v) if i dont set 2.3v i get completely random restarts (could be after afew hours or afew days), all passed with prime and occt.
just in case, after bios reset ddr is set to 800 as default ,go into bios and set divider to 1066, then set timings to 5-5-5-15 (dont use auto/sli ready) bios sets strange timings by default at 1066 then set voltage and save.
I've tried everything and even chatted with MSI Techs over it all, been back and forth between MSI and OCZ for about a month now.. bottom line, MSI told me was that they don't certify or support OCZ ddr1066 on the K9N2 SLI Plat; which OCZ Techs told me, basically. B.S! ...claiming they tested the Board themselves when it came out. However OCZ doesn't even have the Board listed on their RAM Configurator on their website; which they claim is MSI's fault... and so on, and so on...
Anyway, OCZ is offering to swap my Reaper Set for a different Model set which they claim is more reliable on AMD processors. Probably their Gold or SLI model set I'd guess; they don't even advertise on their website any difference in their sticks being "Intel Certified" or "AMD Certified" ... and so on.
Worse case scenario; if in the end whatever they give me still doesn't work, I'll EBAY it and try a set of those geIL Black Dragons.

Welcome to the forum DaaDoctor
If you creat a signature (in profile) it will save you having to type your spec's out each time or us looking for it. Use mine as a template.
What PSU are you using ? Can you list the power output ? (writen on side of psu)
Going from your specs you listed your graphics card is very hungery on power so I would suggest your psu isn't up to the job under load.
Post the spec and we will know for sure.

K9N2 SLI Platinum video won't initialize with monitor connected

Hi,
I've gone through the RMA process with my vendor and I am on my third motherboard right now and I am still having an issue (so, basically, nightmare scenario here ). The first and second motherboard failures seemed slightly different but the failure seems to be the same for the second and third and it is making me think that another factor may be at play other than the motherboard. All of the failures have been with the integrated video (which is all I plan to use at the moment --I don't even own a PCI-E video card right now nor have any plans to get one in the near future).
In the first motherboard, everything seemed to work (as far as I could tell --4 green diagnostic LED's and all that) but no video signal was produced. Testing with an antediluvian Virge DX based PCI card (some of you kiddies may be too young to remember such things) did show normal booting with that video card (as far as I allowed it to go) and I suspect, from the pattern of hard drive activity, that with the integrated video the boot process was also normal (I just couldn't see it because of no video signal being produced). But that is past and has been RMA'd.
The replacement motherboard and the motherboard replacing the replacement motherboard, on the other hand, have seemed unable to initialize video whenever my monitor is connected but if the monitor is not connected, they work fine (but then video defaults to a 1028x768 mode and I cannot run my monitor at native resolution). Curiously enough, my second motherboard worked correctly twice before exhibiting the described behavior making me think, at the time, that I just got really unlucky and simply had had it fail shortly after testing it those two initial times.
Not being able to initialize video while the monitor is plugged in means that if I try to start it while the monitor is attached, the motherboard will not even POST and that the diagnostic LED's will be stuck at the video initialization stage (three reds, and one green at group 4).
Furthermore, if I start it with no monitor attached and plug the monitor in after I get 4 green LED's, it will start booting the OS (Windows XP) but the screen will go black when the Windows XP logo should be appearing. I can also leave it unplugged until it should be at the Windows XP logo stage (or plug it after the 4 green LED's and unplug it again before the video mode switch happens) and when I plug it back in I can see the Windows XP logo. However, as soon as it switches to the Windows XP desktop, I get a black screen.
And again, if I leave the monitor unplugged until the Desktop should be showing up and I plug it in at that point (or go through the process of plugging and unplugging the monitor while avoiding having video mode switches happen with the monitor plugged in) I do get a Windows desktop at the 1024x768 resolution. Once in the desktop, as far as I can tell, I can do anything there that I normally would be able to do (so I mostly have a working system, as far as I can tell). I have even installed drivers, verified that the sound works, etc.. I will still do a repair install at some point because I am not doing this the "right way" and I probably needed to do it anyway (though I think it's using the right kernel and everything --showing 3 CPU's, etc.) but I am not looking for answers with that as my issue shows up before the system even goes through POST. Again, note that I cannot even take advantage of my monitor's native resolution with the current kludge.
Curiously enough, if I try to switch to my native resolution of 1920x1200 it will do it but only by switching me to a virtual 1920x1200 desktop on a 1024x768 display (so there's no actual video mode switch involved and the desktop becomes bigger than what my monitor can show). It's as if part of the subsystem is reading the monitor and "knows" that it supports 1920x1200 but another part of the subsystem is just assuming some sort of 1024x768 default common lowest denominator for digital displays. I attribute this to the fact that video has been initialized with no monitor connected.
I originally had a 350W Enermax power supply (which worked as long as the monitor was not plugged in) supplying 32A on the +3.3V rail, 32A on the +5V rail and 26A on the +12V rail but I replaced it with the power supply shown on my profile (which was probably totally unnecessary as I'm only using the integrated video --but hey, I now have a blue light coming from my power supply so that makes it all worth it ). I suppose both power supplies could work badly with this motherboard model but it seems exceedingly unlikely that that would be the case (specially since everything works as long as there is no monitor plugged in during video mode switches).
I currently am running it, on cardboard, with a single stick of RAM (on the slot next to the CPU) and nothing else connected to it except the power supply (including JPW3 & JPW4), the CPU, a hard disk with a working Windows XP install, a mouse on the mouse port and a keyboard on the keyboard port (specification as on my profile minus one RAM module). I did play with RAM timings at the request of tech support but I can't imagine how it could be a RAM problem when everything works as long as a monitor isn't plugged in during video mode switches.
I did update the BIOS from 3.4 to 3.5. 3.5 did not seem to be available at the time of my previous motherboard and I knew it was a real long shot for this to be a BIOS issue that would be fixed with the 3.5 update (specially since the update mentions only CPU support stuff and nothing about video) but I am desperate. Yes, I have done the whole resetting the CMOS thing.
I am even considering the possibility that there may be some weird incompatibility between the video on this board and my monitor (under the assumption that, quoting Holmes, once you have eliminated the impossible, whatever remains, however improbable, must be the truth). I don't even know how that would work. Note that my monitor worked in my previous system with the digital input (my previous system is no longer available to me for testing --but I did get a chance to test it, after having problems with my first K9N2 SLI Platinum motherboard which I returned, and it worked). Note that my monitor works with the system in question (I simply cannot have it connected while there's a video mode switch under way). Note that the lack of a picture seems to be related to the motherboard as evidenced by it being stuck at the video initialization stage if I attempt to start it with the monitor connected.
Any wild ideas? I do not want to return this motherboard a third time and I specially do not want to return this motherboard a third time if it's something that can be easily fixed.

Have you tried with just memory stick in 1st DIMM near to CPU socket and mainboard out of PC case?
Yes, I currently am running it, on cardboard outside the case, with a single DIMM (on the slot next to the CPU) and nothing else connected to it except for the power supply (including JPW3 & JPW4), the CPU, a hard disk with a working Windows XP install, a mouse on the mouse port and a keyboard on the keyboard port (specification as on my profile minus one RAM module). And it works,... as long as the monitor is not ever connected while video mode switches occur (including power on). And this is exactly how the previous motherboard which I returned also behaved.
Addendum: As an additional note, I have tried the other DIMM on the same socket by the CPU with the same results (everything works as long as there's no monitor connected during a video mode switch). I also managed to make a bootable Memtest86+ (is that what people use to test memory these days?) USB stick and I am running it right now. It has shown no errors right so far but it has only been running a few minutes. I do not really expect any memory errors to be at fault since they would have to be magical memory errors which only cause problems when there is a monitor connected while a video mode switch is happening but I'm desperate to try anything to find out what the issue is.

SPDIF on K9N2 SLI Platinum

Hello, I just started to use the Geforce GTX 280 for my monitor and 50" DLP TV for dual video.
I have one DVI to HDMI to my monitor and the same setup to my TV. The TV is working like it should as a monitor but I am not able to get any sound. how am I able to get the sound to go through the SPDIF to my Blu-ray speaker system as it to has an SPDIF port?
AMD Phenom 9600 Quad Core
K9N2 SLI Platinum Mainboard
Geforce GTX 280 Video Card
OCZ Reaper v3 4GB 1066MHz
OCZ 750 Watt Modular PSU
Windows Vista 32bit SP2

If you want to use HDMI w/ audio, you must have vista or supported OS, and have spdif cable going from the video card to the motherboard connected. If your using DVI, then you must setup a separate cable from your sound card to the tv or stereo; which is usually just a male 3.5mm phono jack on both ends. Depending on your receiver or TV you may need a phono to RCA converter. However you can go digital if you like, using the rear spdif's and go str8 from optical to optical.
Keep in mind if you don't have ext. spdif. you can only go out analog from your soundcard or internally through HDMI which requires Vista or other supported OS.
