Over heating
(Click here to view the original thread with full colors/images)

Set-up
Mobo-DFI Lanparty UT Nforce 3 250Gb
Processor-AMD 3000+ 64bit
Ram-Samsung 512
Video-ATI 9200 Radeon SE Saphire
I just bought the Mobo and proccessor new. My old ones got zapped in a power-surge. When playing high-end video games. I am noticing that my monitoring software is showing PWM IC reading above 50 C. Playing Call of Duty. It will crash after several minutes.
I currently have the newest driver from DFI installed. I am using ATI's 4.3 driver.
Wondering what the PWM IC reading is for?
Wondering if it's possible my video card might be bad as well?
I know there is a patch for COD for ATI cards. Going to install that once I get home. And try again. If anyone has any idea's what might be causing this. Right now I just have the stock cooling for the board in my case. I am planning on adding a system fan just cuse. But does anyone have any idea's what could be causing this?
Thank alot for any help

heating is the obvious cause, although any hardware thats going bad could be the cause.
no idea what the pwm ic reading is for, although i could make a good guess. look it up in the user manual for your software.
if its your cpu temperature, youre overheating. at that point, you need to check your case and chipset temps as well to determine where the problem is located.

My other temp's are fine. Just this one is high. As for the PWm IC, it's not in the manual. The one I got from DFI basically just shows mobo lay-out. PWm, or Pulse Width modulation. Has to do with 64 Bit processing, is all I can learn from google.
Just dis-covered my friend that I got to install the machine. Over-clocked my AMD 3000 chip from 2.0 to 2.4 GHz. When I get home from work tonight, planning on un-clocking it. To see if this will clear out the problems.
But wouldn't you think if part of the processor is over-heating. Shouldn't it crash the whole system, just not the appz<video game> that I'm running at the time?

Overclocking == overheating. All over clockers know this and that's why they use special (read expensive) heatsinks and over-sized fans (and vent the heat straight out of the case). Unless this is what your 'friend' installed for you, then a 20% overclock is asking for trouble.
When the CPU overheats almost 100% of todays motherboards will detect this and shut down the PC (rather than let the CPU melt). Of course you can set the shut down temp. (or even turn off the temp shut down completely) by changing BIOS values, although to be honest 50 degrees C might not be high enough to trigger a shut down.
As it overheats, random errors are going to occur as the CPU wanders in & out of spec. When playing a game almost all CPU cycles are game cycles - so any random error is most times going to effect the game.
However the main cause of the problem is likely to be the Video card - 'overclocking' the CPU theses days means winding up the FSB - and this typically means that everything else inside the PC is over-clocked too - and that includes your video card. The market for Video cards is so competitive that most cards have been clocked right to the edge of over heating already ...

That might have been at least a little bit true before PCI lock, but not now. Increasing FSB speed has little to nothing to do with overclocking the video card.

those two concepts do not mix well. youll be lucky if you dont end up with fried cpu to go with your bacon in the morning.

I don't think I have ever seen somone do a 20% overclock on an athlon 64 with stock hsf, thats suicide! I might be able to see it if you did a little ventilation engineering but other than that... You'd better get a thermalright hs and a kickass fan if you wanna be serious about OCing a 64. The reason why you only crash in games is because games use up the most cpu time, thus overheating it.

Thank guys, I had no intention off over-clocking the board myself right away. I was planning on having the system for a month or two. To make sure everything was stable. He just figured that the board could handle it. Last time I get him to touch any of my gear. Once I un-clocked the system everything was fine.
I have two extra fans in my old system. I just haven't moved them over let. But with the system back at default. Everything is cool
