Need info on system stability

[jimmy]

I've overclcoked my fsb from 133 to 151 and I can run the CPU Stability Test for 9 hours w/o a problem. However, I try to run UT and it crashes in an hour (It crashed in only 2-3 hours unoverclocked). Also, 3DMark2000 worked while o/ced in windows 98SE, but keeps failing in WinME. Is my system unstable, or is it my software that's having problems? Can someone tell me how to loop the Q3 demo so I can try out another program?
Please help

oh, I forgot to mention, the CPU temp never goes above 46C, the board never goes above 25C and my video card is a GeForce 256 and it never felt very hot, even right after UT crashed.

I had similar problems when using the CUSL2 motherboard, and the CUV4X motherboard. On the CUV4X i fixed the crashing by lowering the +3.3 voltage, and on the CUSL2, i fixed the problem by providing better cooling to the frequency chip on the motherboard. It was not the video card that was causing it to crash nor too high of a fsb on either motherboard. You should try doing both of those options i gave (one at a time). You may even try increasing your vcore if its not too high already (try to stay below 1.85 if possible)

heres how to loop quake 3:
Open notepad make a file called config.cfg typed in this:

set loop "vstr loop1"
set loop1 "set timedemo 1 ; demo demo001 ; set nextdemo vstr loop2"
set loop2 "demo demo001 ; set nextdemo vstr loop1"

save in baseq3 folder when in quake3 hit the ~ key type in "exec config.cfg" hit enter then type "vstr loop" and hit enter...there is another way to do this but I forgot how but this way does work

I too am having some CUSL2-C Problems. My systems is rock solid at 933 @ 1.8v but won't even post at anything higher than this. And any voltage above 1.8 doesn't work at any speed. My CPU is cooled with a Global Win FOP 38 and I've never seen the temp ever rise above 46c. And the system never goes above 30c. I would like to try that cooling the frequency chip trick. Unfortunatly I'm stupid :) because I have no idea where that is. Are those the DIP switches that page 22 on the manual talks about? How did you cool them?

Thanks for the info. My voltage is currently at 1.75, so I could try raising it a little. Where is the frequency chip on the CUSL2-C?

The frequency chip is not hard to find. It is covered by a big green heatsink. It is not the dip switches, its an actual chip on your motherboard. It gets pretty hot on the Via chipset boards, and almost as hot on the 815 chipsets (CUSL2-C). Located between the AGP slot and the processor, its about a 1 inch green square. All you have to do is find an old flat heatsink from an old cpu, attach a 40mm fan to it, then use some thermal paste and a tiny drop of super glue and you got MUCH better cooling. Of course, you have to remove the sh*tty heatsink (if thats what you want to call that horrible green thing) that is already on the motherboard. it can easily be removed by pushing out the 2 plastic tabs on the back of the motherboard. You might need some needle nose pliers to do that. Its also very important you make sure the heatsink makes FULL contact with the frequency chip. If it does not, you will have instability problems at almost all fsb speeds. One last thing, there are capacitors on the motherboard around the frequency chip, so make sure your cooling device fits before attempting to glue it.
