K9n platinum voltage question

Hello everyone,
I'm new to the boards and I hope someone can help me out.
Let me throw my specs out first:
mobo: msi k9n platinum 1.0 (bios 1.5) (ms-7250-20)
cpu: opteron 1212 (voltage should be 1.3/1.35)
ram: ocz 6400 platinum (5,5,5,15 2t) (2.1v)
gfx: evga 7800gt
ps: sunbeamtech 550w(+3.3v=28A, +5v=36A,+12v1=20A,+12v2=18A(30A/35*A))
This board does have the shut down problems, but I have done the work arounds and fixed 98% of them(memory timings were the most important to fix these)
My question is how do I set the volage for the cpu? I know go into the cell menu->cpu freq config->and change the voltage...but when I set it to 1.3~1.35, the cpu voltage in the H/W monitor & on the main cell menu page will show a .28 voltage increase. My cpu temps are also through the roof (35 idle/ 68+ load).
Right now I have my cpu voltage set at 1.25 and it seems mostly stable, but the cpu Vcore shows 1.528v in H/W monitor, and cell menu.
Also if I keep my voltage at 1.2 my temps are very low (20 idle/ 38 load)
When I use cpu-z it shows the voltage that I actually set.
Anyone have an answer or fix?
Thanks for any and all replies.

leave CPU vid to Auto, you no need to change CPU vcore. voltage moving -/+ 0.05 is normal.
take care about CPU temp... your CPU is overheating and become instable, 68C+ is very high... re seat CPU ensure its mounted well, aplly new thermal paste, but do not put too much!! here are few wrong examples:
your under load temp should not exceed 55C. you may need to get better CPU cooler if no change.

K9N Platinum - northbridge question

Does northbridge on K9N Platinum support thermal shutdown? 'Cos as far as I know there is no thermal sensors and I'm really worried when I'm overclocking.
Sorry for my english

Since nVidia does not publish Data Sheets, the only way to find out may be to install a monitoring utility to see what it reports. There's nVidia's nTune but I wouldn't let it near a system of mine; maybe try http://www.almico.com/speedfan.php and see what it reports - the initial install will show just numbered values, e.g. Temp1, Temp2, etc. There'll be a K8 Core, which is the thermal control temp for the CPU and one of the Tempn values for the CPU monitor, plus one for "system" which AFAIK is the monitoring chip itself. If it sees a nForce chip temp it should be obvious which one it is.

P6N SLi platinum, Voltage questions for oc to 3Ghz

Hello dear forumusers,
I have recently overclocked my cpu by a little (2.76 ghz instead of 2.67Ghz) however, my memory is a little bit slower because its voltage is on auto and I cannot get it on manual .
I can set the timings and speed ( 667Mhz) but it runs on 638Mhz, so I need to adjust the voltage but as said I cannot change it
Is this resolvable by updating to another bios or is it just impossible?
Bios is v1.0
Edit, found already, page up page down does the trick

I've been experimenting a bit and now reached 2.98 Ghz with stock cooler, idle @ 25C, loaded @ 55C
The fsb:dram is 9:8 and mem is now running at 662Mhz, was 638 Mhz????
I cannot set the divider myself unfortunately, or me don't now how to (see specs for info)
One more question( you can put this post in the overclock forum if you like) I want to reach 3Ghz as a max, but as soon as I set fsb on 1500(now 1490) it will boot but within 10 to 30 min orthos will stop.
What do I have to do to get it stable, my mem is running on 1.85V as described by kingston and I raised the NB by .025V, now 1.275V and on 2980Mhz it's rocksolid, no errrors after 5 hours of orthos.
Do i have to raise the Vcore or something else, any comment is welkom
Thanks in advance

K9N Platinum Ram Voltage??!

Hello dudes!
Can someone tell me what ram voltage K9N Platinum is?!
O ill buy some memories, with 1.9 or 2.0v... and just wanna know what is ram voltage of this mobo...
i know asus m2n-e max is set to 1.95v... but dont know about K9N platinum...
So... if anyone can help me, i ll aprecciate..
tnkz a lot!
Ahhh... almost forget... is OCZ compatible with this mobo??!
Tnkz a lot!

I have the K9N Platinum motherboard aswell, and the standard DDR voltage is 1.80
OK, let me make it clear. there is no standard voltage on the mobos. the default voltage depends on the memory you are using. different memory modules will default at different voltages, as per the data that the manufacturer placed in their SPDs.
if you are talking about JEDEC default voltage for DDR2, then yes, it is 1.8V, with a maximum of 2.3V. you can read about timings and voltages for the JEDEC standard here:

K9N Platinum Motherboard problem???

Hello. I got a K9N-Platinum motherboard and AM2 X2 4600+ CPU. However, I often got the following problem:
My system sometimes froze, no response at all, couldn't use mouse and keyboard of course.
1) I set up the system to shut down monitor after 60 minutes. However, sometimes the system couldn't
recover, all parts stopped working, including hard disks.
2) When the hard disk is transferring, such phenomenon could happen again.
Finally I found a solution. I had to manually set up the CPU voltage to "1.35V" in BIOS which can resolve my problem completely.
This problem only happened when the cpu voltage was set to "auto".
I thought it was a power management problem, so I installed hotfix KB896256 and KB924441 and all dual-core
cpu optimizers, the problem still existed.
My system is as follows:
K9N Platinum with BIOS 1.6 (601-7250-070********)
AM2 X2 4600+
Geil DDR2 800 1G*2
Inno3D 7900GS
Western Digital Raptor 37G
Liteon 18X DVD burner
500W PSU
I want to know whether this is a defect of my motherboard. Any advices would be appreciated.
Thanks.mate.

Can understand the question "what CPU core do you have"?
I have the AM2 dual core 4600+ CPU,Windsor core, 89W watt.
yep that i have asked, well there is nothing to worry about voltage applied manually matched with your default CPU vcore.

K9N Platinum - Wrong CPU Temperature in BIOS

Hi, I have a K9N Platinum (7250-020) with the latest 1.3 BIOS and an AMD X2 3800+. The CPU Temperature in the BIOS has a negative sign in front of it, and it seems to always report -48*C. I tried the latest nVidia nTune and it was reporting the CPU temperature to be 208*C, which is absolutely impossible...
Does anyone have the same problem? I searched around and it seems I'm not the only one, but I still cannot understand if it affects only some K9N Platinums or all...
Thanks.

I assume you are talking about checking voltages as reported by the BIOS in the HW Monitor page, not physically checking them with a multimeter, correct?
I'll take a look at the numbers in the BIOS, but last time I checked they were ok.
As for raising the issue with MSI, eventually I will, even if they ask you soooooo many questions (for good reasons, I know...) that it would take me half an hour to fill that form...
I've checked with both and software is a little out from what a multimeter state's. Only check with a multimeter if your happy to do so. http://forums.extremeoverclocking.com/showthread.php?t=137886 offer good advise if using a multimeter .....
The only issue I see is the AUX connector for 3.3v with ATX2.0 spec (Modular cables etc)

Planning To buy MSI K9N Platinum + AMD X2 3800+

Hello everyone,
as the title as Iam planning to buy a MSI K9N Platinum board with an AMD X2 3800+ for a new system build. Ive been out of the game for a while, the last time I was really up to date on computer technology is when the AMD XP 2500+ Barton was the hottest thing on the market, some what of a new comer to dual core technology. I have a few questions, mainly about the board it self. I did a little searching and that answered some of my question but I have a few more.
Ive read a lot about the shutdown problems from the board when transferring large files or burning DVDs. I have a few questions about that.
From what I see so far, this is a very informative forum and I appreciate any and all information. So here goes:
1) It says on the MSI website that the ram slot for this motherboard is at 1.8 volts. The ram Iam planning to get is OCZ Platinum EL XTC PC2-6400 1GB 2X512 DDR2 CL4-5-4-15 240PIN DIMM Dual Channel Memory Kit. On the OCZ website it says that the ram modules run at 2.1 volts. My Question is if I stick this ram in the mother board will it boot long enough for me to go into the bios and change the ram voltage to 2.1 volts?
2) Now Ive read about the shutdown problems with this board. Ive seen a lot of people up the VCore to 1.35V. If I do this along with a bios flash, will this take care of the problems?
3) Now the dealer that Iam buying my PC from didn't have this board in stock for the last week. He just got them in 2 days ago this week. Therefore Iam assuming he has the lastest version of these boards. Now are these problems taken care of on the new version of these boards? If not what can I do to get rid of them?
4) Is there anything else I should know about this motherboard?
Thanks for the the help.

Yes, you could set up manually the voltage to 2.1v perfectly I've got one k9nsli p, with an amdx2 3800+ whit 2gb ddr2 (512x4 twins pack corsair xms2 ddr2 800) that works at 1,9v
2) Now Ive read about the shutdown problems with this board. Ive seen a lot of people up the VCore to 1.35V. If I do this along with a bios flash, will this take care of the problems?
My shutdowns problems was resolved by unnistallin' nvidia IDE controller, nothing about vcore or flashin bios... I keep original bios version 1.0 & Core center shows vcore at 1.33v
3) Now the dealer that Iam buying my PC from didn't have this board in stock for the last week. He just got them in 2 days ago this week. Therefore Iam assuming he has the lastest version of these boards. Now are these problems taken care of on the new version of these boards? If not what can I do to get rid of them?
Good question... 2morrow I'll check on the box of my k9 the part number and will post it
4) Is there anything else I should know about this motherboard?
The first week, I was desire burn my k9 shutdowns... shutdowns.... shutdowns... after I find the cause of that ShiX$/#(! (nvidi IDesuxs controller) my life is happy!
good luck

K9N Platinum: upgrade to X2 5600+ or X2 6400+?

Hi. This is my first post. I would like to upgrade my CPU on my K9N Platinum and I have a couple of questions:
1. I have narrowed down to two: X2 5600+ (89w) or X2 6400+ (125w)?
- both have the same L2 cache, but the speed and wattage differ
- I play some games and some video encoding
2. Will the power supply that I have be sufficient for the X2 6400+ and support a video card upgrade to a GeForce 8800 series?
Many thanks in advance.

but doesn't overclocking too much or running certain clock speed for too long, will shorter the cpu's life span?
I have a XP1700+ In a MSI K7N2 Delta L, which is default 1.47 and I have had it at 2.0 for nearly four years, aftermarket Copper Core air cooler. The 5000+ Blackie's that I have are at a 16 Multiplier for 3.2 speed. I have one in a abit KN9 SLI and the other in my MSI K9A2 CF both run cool. I am not overclocking my 6400+ Blackie right now, but I would expect it to have a good bit less Overclocking potential. It runs super at default though.
I had a Overclocked ATI 9500 Pro and it died after two and a half years, but I really had it cranked, so yes and no to your question. Good cooling alleviates most of the possible damage. If you are Cool then you are usually okay.

K9N Platinum Sli trouble

so i have assembled my new system:
Athlon 64 x2 AM2 4200+
Zalman CNPS9500
K9N Platinum Sli
OCZ DDR2 PC2-5400 667MHz EL Gold Edition 2GB Dual Channel Kit
XFX Geforce 7600GT 256mb XXX edition (another one will be added today for SLI)
a SATA drive and a DVD burner (these arent important for the issue)
temps = idle 30-34 c, load - no idea havent checked that yet
Enermax Liberty 400w PSU
ever since ive assembled the system i ran into some strange thing - during the changing of setting in the BIOS it froze a few times.
Neverthless i was able to run the system, install windows, start to install other software (yesterday)
and today when i turned on the system, windows booted up, and sudenly it restarts and freezes up in pre bios stage...
Reset or Shutdown resulted in power up, but nothing happening, the monitor did even got out of standby...
after a few tries, and about ten minutes without power, it started up and went to a bios stage, giving a CMOS Bad Checksum Error... loaded bios with fail-safe settings, system worked fine and booted up windows... windows worked fine aswell, attempt to reboot and change the bios settings, gave a Bad Checksum from start and a freeze in bios. System is not getting to bios stage once again...
A Mobo problem that warrants a vist to the store, to return it?

oh and the PSU got two +12v rails with 20a on each, should be enough?... (though Enermax seems to have troubles with math since according to them 20a+20a=30a)
trust me, enermax doesn't have problems with math. this is actually how it works. you cannot just add up the 12v rails to get the max amps on the 12v.
Quote from: mr.flint on 26-August-06, 00:33:23
managed to boot with the suspected mem stick - running memtest-86 - counted 746321 errors and then froze.... looks like the stick IS defective
try to increase the memory voltage a bit. i think you should be safe up to 2.1V. if you still get errors in memtest, then you have a faulty memory module.

K9N Platinum bios version & cpu support

Hi!
I need some help to clear up some questions regarding my MB.
MB: K9N Platinum, Cpu-z states my bios version is 080014, but i cant see it in the bios list for my MB, so what version is it?
Im currently running with a Athlon X2 5200+ Windsor, and i have got my hands on an Athlon X2 6400+ Black Edition, as far as i can see my MB is supporting that cpu, but is my current bios up to date for the cpu?
I have downloaded the MSI usb bios flashtool and i have set it up, and it boots in dos, but when i run memtest the program just says in one line memtest and a flashing + nothing more happens (i have left the pc for about 3-4min but no change) i feel that im starting to push my luck, and i dont want to kill this MB since its my work and gaming rig.
System spec:
MB: K9N Platinum
CPU: Athlon 64 X2 5200+ (want to install Athlon 64 x2 6400+ BE ID: ADX6400IAA6CZ)
RAM: 6Gb DDR2, 2x1Gb, 2x2Gb
GPU: GIGABYTE GTX260 Super OC Edition
PSU: CORSAIR HX520W

I need atleast Bios 1.8 to get my MB to work with the new cpu.
So now i just have to figure out why mem test wont run.

Memtest do have some bugs. You can do test with Orthos instead:
https://forum-en.msi.com/index.php?topic=103598.msg760534#msg760534
To check is your system is stable or not.
Once done you can ignore Memtest when asking after booting from the USB key
Also leave 1 memory stick only temporary in the 1st DIMM close to CPU socket before BIOS flash.[put remaining sticks back when BIOS flash is done/finished].

K9N PLATINUM(NON SLI) DUAL CHANNEL MODE PROBLEM

hi
put a new system together with the following specs:
amd am2 3800+(2ghz)
k9n platinum 1.20 bios
2x512 kingston ddr2(667mhz)
pci video(yes not pci-e)have not decided which vid card to get yet.
500w psu 12v 35a,5v 25a,3.3v 25a
liteon dvd burner
seagate 300gb ide 7200/16 meg cache windows xp-pro sp2 with all updates.
not overclocking or even trying to.
no sata drives connected.
has never failed to post,boot windows and no lockups or blue screens.
ok,i am trying to get the memory to work in dual mode.
everytime i put the memory in the dual mode slots,the cpu clocks down to 1ghz instead of 2ghz.
verified by bios,windows and cpu-id
i have tried different memory(both ddr2 533 and 667)667 installed now.
also never had any install problems with windows and everything runs fine until i tried dual mode.
after the cpu clocks down to 1ghz,the only way to get it back to normal is a bios reset( load defaults
or press red button).
if i leave the memory as single channel then i have no issues.
also cpu-id says the chipset for my board is nforce 550,i thought k9n platinum had 570 nforce chipset?
this might just be a problem with cpu-id though.
any thoughts on the cpu down clock problem in dual channel mode?
thanks,jeff

1 assume you can get into BIOS with 1 stick only?
Go into the BIOS and manually set the timings and voltage to what your memory manufacturer recommends. Use a 2T command rate and see if it works.
Try both "sets" of dual channel slots, i.e. the two left slots or the two right slots.

K9N Platinum Supported CPU's

Hi everyone,
My question is fairly straightforward. I currently have a MSI K9N Platinum AM2 NVIDIA nForce 570 Ultra MCP in my HTPC. Long story short I found out that my CPU was not powerful enough to decode 1080p content so I have purchased a new CPU, a AMD Athlon 64 X2 6400+ Windsor 3.2GHz 2 x 1MB L2 Cache Socket AM2 125W Dual-Core Processor: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103228
According to the CPU support list here:
http://global.msi.com.tw/index.php?func=prodcpusupport&prod_no=252&maincat_no=1
I should be able to use this processor with my motherboard with BIOS 1.A, so I downloaded Live Update and flashed the BIOS to 1.A (I believe it now shows it as 1.10, though I am not sure where that is noted in POST) in preparation for the new CPU (the flash went fine).
I am wondering if anyone has any experience using this motherboard with this CPU? Is it truly compatible or the CPU simply too new an edition for my motherboard? I can probably still cancel my order and get a 5600+ or equivalent if necessary.
I appreciate any feedback/responses.

I bet it's your videocard not handling it very well.
Somewhere rings a bell that nVidia is lacking hardware decoding with videocards, but can't remember exactly what it was.
Well that is the long story short part :D. In a nutshell yes it is my video card, I have a 7900GT and essentially nvidia's purevideo decoder for HD content has NEVER worked properly. This basically means that the CPU has to handle the entire decoding load, which my old CPU is incapable of doing (hence all the stuttering, audio/video out of sync issues I get). Basically I had two options:
A) Buy an ATI, one of the 3xxx series that actually does x264 decoding
B) Replace the CPU with a faster/better/dual core one (many codecs can now use dual-core CPU's for decoding HD content)
In the end I made the decision to replace the CPU to resolve the problem because while buying a 3xxx series card does appear to work WONDERS for HD content decodes (it reduces the CPU load to 5-10% in some cases) if the file is encoded in some non-standard way that the GPU decoder doesn't recognize the load is going straight back to the CPU (like my Nvidia 7900GT is doing). This way I figure I get a better CPU and it should be able to muscle it's way through decoding anything I throw at it. If I need to replace the GPU someday or want to do it in order to reduce the load on the CPU I can always look into one of the 3xxx series (I hear that the nvidia 8600's might actually do some HD decoding as well) though I have really become skeptical of ATI cards lately.

K9N Platinum and Corsair CM2X1024-6400 **UPDATE - FIXED**

I'm trying to help a friend with their new K9N Platinum motherboard. We got everything installed successfully, but after getting into Windows, the machine will just freeze up randomly doing anything, software install, whatever, within a minute, or sometimes as long as 5 or more minutes.
Basic specs:
K9N Platinum motherboard
Flashed to BIOS version 1.4
AMD Athlon64 X2 3800+ (65W) socket AM2
BFG Geforce 7900GS
500W PCI-E power supply
Wester Digital 120GB 7200rpm SATA HD 8MB cache
Single 1GB stick of Corsair CM2X1024-6400 RAM (DDR2 800MHz) - Brand New - DIMM slot 1
Windows XP Professional with SP2 and all windows updates installed. (using IE6)
Installed all latest drivers from MSI's website for this board.
We tried 1st with DRAM timings on auto, then tried to set the timing manually according to Corsair's spec sheet for this module, including memory voltage at 1.9V.
We think it might be a bad memory module, because after getting into Windows, we run memtest, and errors are detected within the 1st minute. We have RMA'd the RAM module. I'm wondering though if we just didn't have the timing for the memory set correctly in the BIOS.
Is anyone here runnning this exact memory successfully, or is this board incompatible with this Corsair module? If you are running successfully, did you have to change the SPD timings manually, or are you running using the SPD Auto setting?
If you had to use manual setting, any help with the values to set in DRAM Timing would be greatly appreciated. As much detail as you can provide would be great. Thanks for your help.

Ok, still having major problem with running world of warcraft. This PC freezes/locks up in the game every single time within 5-10 minutes of play no matter what we've tried so far. This is not a shutdown or restart problem, just a freeze/lock-up symptom. I'm getting a bit frustrated at this point. No other problems in windows are encountered. We can work in windows with any other application, like adobe photoshop or any other software, with zero trouble. I'm beginning to think this is video card related somehow with this 7900 GS card.
For added info, the video card being used is this;
BFG Tech BFGR79256GSOCE GeForce 7900GS 256MB 256-bit GDDR3 PCI Express x16 Video Card
Chipset Manufacturer NVIDIA
GPU GeForce 7900GS
Core clock 525MHz(vs. 450MHz standard)
PixelPipelines 20
Memory Clock 1320MHz
Memory Size 256MB
Memory Interface 256-bit
Memory Type GDDR3
3D API
DirectX DirectX 9
OpenGL OpenGL 2.0
Ports - DVI 2
The mouse used is a logitech USB track ball mouse if that has any bearing on anything. No mouse troubles though, just thought I'd mention it.
Here's what we've tried so far;
Updated to BIOS version 1.4. This was done after the Windows XP install though, so not sure if something is hosed up here.
1) We set the RAM timings to 5-5-5-12-2T and 2.1Volts in BIOS manually, as per direct recommendation from Corsair.
1a) Ran memtest all night for about 9 hours straight and no errors at all detected. So I'm guessing this isn't a RAM problem really, but who knows .
2) Installed the Windows XP SP2 Hotfix for Dual Core Processors - hotfix KB896256
3) Installed the AMD Dual Core Optimizer from here -->http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_13118,00.html
4) Updated the Nvidia system drivers with the nForce 550/570/570/590 SLI (C51+MCP55) driver package 9.19 WHQL from MSI's website here--> http://www.msi.com.tw/program/support/download/dld/spt_dld_detail.php?UID=730&kind=1
5) Currently running Nvidia video driver version --> ForceWare Release 90 Version: 93.71 Release Date: November 2, 2006 WHQL Certified.
6) Ran a complete Direct X diagnostics via dxdiag. All tests passed successfully.
7) Tried to install the AMD Athlon™ 64 X2 Dual Core Processor Driver for Windows XP and Windows Server 2003 Version (x86 and x64 exe) 1.3.2.16 from here -->http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_13118,00.html
But it would NOT install because it says I have to first uninstall the current driver via add/remove programs, but it's not listed there, before installing this one. So, I have no idea where to look or how to do this, I'm afraid of messing up the processor driver. Can someone explain how to install this driver, and would not having this installed possibly be a potential cause of the game lock-ups?
I don't know what else to do. Could the version 9.19 Nvidia SATA or IDE drivers I installed be causing these game lock-up problems? If so, do I just go into device manager and just rollback drivers for all of the devices listed under the "IDE/ATA ATAPI Controllers" in device manager?
Again, this was a fresh windows XP Pro install on a newly formatted hard drive. Obviously something is fubar, but I'm running out of things to try. Maybe going into BIOS and "load optimized defaults" and start over?
Lastly, the tech specs on newegg.com for this video card say "A 350W PCI Express compliant system power supply (with 12V current rating of 22A or more)" is needed. Since the 500W power supply we're using has 2 separate 12V rails rated at 20A each, could this be the problem?? I'm open to suggestions. Thank you.

K9N Platinum - Doesn't boot with PWR2 connected

Hi,
I've just built a new PC with a K9N Platinum Motherboard (7250 Ver 1.0)
I immediately discovered a problem:
-If I connect to the power supply the PWR2 Molex (the additional power connector on the motherboard, to provide additional power to the video card) the system doesn't boot. Computer's LEDs get on for half a second, then it shuts down.
-If I deconnect the PWR2 connector, computer boots fine.
Bios already flashed to 1.51... no results.
It sounds weird to me. I have an Enermax Noisetaker II 485W PSU, the CPU is an Athlon X2 65W...
Have I got a damaged mainboard?
Thanks for support

Just tried... nothing. Lights and fans turns on for half a second, then everything dies.
I tried to remove video card too, nothing changes :(
sound like somethink is shorted. try take board of case and retry. it maybe dumb question, but are you connect 4pin cable in a right direction?(i know its can be plugged in one way only, but if you use little more force can be done...)

K9N Platinum SLI - Powering up the PCIe cards

Hey everyone,
I've got a K9N Platinum SLI board. This board has a power supply input point called PWR2, which according to the documentation is used to provide power to stable the operation of graphics cards. My graphic card is BFG nVidia 9750 GT. This card has the PCI-Express external power plug in the back, and my power supply has a dedicated (red) connector for this purpose, which I have attached properly.
The PWR2 is currently connected also, into one of the black 12V connectors. Otherwise, everything is running fine and smooth, but I am sometimes (once a day or so) experiencing random shutdowns during intense gaming (playing LotRO). Stress testing does not cause a shutdown: I've ran 3D Mark 2007 straight for 8-9 hours, while having a CPU Burner application toast the CPU at the same time. But no problems whatsoever. No other games exhibit this problem either.
Since I am providing dedicated power through the extra connector at the back of the card, should I leave the PWR2 connector unplugged ? Is there a chance that using these two connectors at the same time causes the 12V rail to overload, and the PSU shuts down to protect itself ? When this shut down occurs, the power LED is left blinking and I need to plug out the wall socket and wait for several minutes before the blinking stops and it starts up again.
My computer has an Enermax Liberty 620W power supply, and AMD Athlon X2 4600+ CPU. So there should be enough juice, at least. I've tried the tips and tricks suggested here. Using USB-connected Keyboard and Mouse does not correct the issue. I've also verified that this is not an overheating issue. My CPU is cooled by a Scythe Ninja tower heatsink and two 12 cm fans. It is possible that the northbride is heating up (it burns the finger on touch when under load), but from the Web, I've understood that the stock passive heatsink should be enough, and that the NB chip can take rather extreme temperatures.
* UPDATE *
Plugged the PWR2 connector out from the MB, and update the BIOS to 1.10. It's working as usual, but haven't ran any games yet. Heavy gaming usually reproduces the issue, so I'll write more when I know more.

Updated information on the case.
I've been running 2 days now with the PWR2 unplugged. I have had zero problems with shutdowns since. The only problem I now have is that the USB keyboard and mouse refuse to work in Windows XP after an initial bootup from powered down state. I have to unplug and replug them at the login screen in order to get them work again.
So, I decided to do a final sanity check, and replugged the PWR2, then went gaming. After 2 hours of playing, my computer shutted down for the first time. Plugging in the cable did not solve the USB problem either.
As of this day, I'm leaving it unplugged. It seems like an irrelevant connector, which just causes problems.
** Update **
After following Bosskiller's instructions on another thread about using the "Clear CMOS" button and then reconfiguring BIOS from scratch, the cold boot USB issues were solved. The USB devices now work straight after a cold boot, with no need to replug them.
I recommend that the PWR2 -connector info is added to the list of known problems in the sticky thread. If you have a GPU card which takes its power from a dedicated rail (and your PSU has a dedicated connector for this purpose), then leaving the PWR2 -connector unplugged might resolve your shutdown issues, like it solved mine.
After all, according to the manual, this connector is used to give more voltage to the PCI and PCIe busses, and some PCI/PCIe cards might not like this idea at all. There is a reason why these cards have an additional power plug on them...
