I have overclocked my opty to 2700mhz on stock vcore and it is prime stable for 12 hours. I have memtested my ram @ 270mhz 3-4-3-8 for 14 passes (8 hours). Both are rock stable.

I have also overclocked my 7900gt on stock cooling from 500/750 (stock overclock) to 576/856. I randomly lock up after a few hours of playing cs. Right before it locks up, i happen to check my temps and they seemed fine at 75c (gpu)

What could be wrong?
 
fine at 75c? That sounds way too hot to me. Dunno how hot those cards are supposed to run, but I'm pretty sure it's not that hot. I'd back way off on the vid card overclock.
 
Sounds like it is definitely your power supply man. Go into your bios and check your voltages and then come back and post them if you don't mind...
 
smart guardian is reading

CPU= 1.32 (1.35 bios)
LDT = 1.18
ATX +5.0v = 5.1
DRAM 2.73
ATX +12= 11.83
NB + 1.5= 1.5
ATX +3.3= 3.32
VBAT + 3.0= 3.07
 
I would have to say it's your overclock.

Try leaving everything at stock and see if it still locks up.


75c is way to high for your GPU.

Also what 7900GT do you have? Some of the factory overclocked ones don't leave much room for further user overclocking.

Your 550 watt should be more than enough power.

I hate to make a second post but what did the OP say that made you think it's his PSU?

His GPU overclock is way high along with his temps.
 
alright, thank god its not the psu because that woulda pissed me off.

The one I have is the eVGA 7900GT CO 500/750. I used "detect optimal frequencies" and that is 576/856.

Both "stock" settings and the overclock (im reffering to both the 500/750 and the 576/856 both idle @ 50c. My ambient temp is about 24c. Ive noticed that if i open up the side the air around the gfx is pretty hot and the hot air is just sitting there. everywhere else the airflow is great.
 
Are you running anything that you need that card clocked so high?

If the machine doesn't lock up at stock settings it's your overclock.

Prime 95 and Memtest won't test GPU stability. Try running multiple passes of 3dMark or something.
 
it only crashes after HOURS of gaming. I ran 3dmark 4 times in a row and it was stable.

i guess ill just go back down to stock and/or change my cooling.
 
It's probably just getting to hot.

You don't need that overclock to play CS:S anyways.

During gaming it should be more like mid-upper 70's at load.
I also have a friend with the same video card, so I would think that the video card would be fine. The temps don't really seem too hot for a GPU. For a CPU, yeah it would be.
Some common symptoms of a defective power supply is random crashing of the computer. Anyways maybe fooling around with your overclocking may help stop the crashing, but if nothing else I would just say look into your psu.
 
Mid 70's is to hot under load period. There isn't an overclocker on this board that would reccommend that as a good temp to run your card at.

Well isn't the core slowdown threshold 125c? That's why I don't think 75-80 would hurt it.

Also you could try checking this out if you would like.


There is alot of conflicting information in that thread. Some say it's to hot others just fine.

Either way the OP has one hell of an overclock on an already overclocked card.
Dollars to donuts that is what is causing his crashing.
 
yeah, guess l will go back to 500/750. I just liked the oc i had before because it broke me over the 10k 3dmark05 score.
