At my whits end.

[OVerLoRDI]

I have an x2 3800 (2.5ghz), Asus A8N-SLI premium (latest bios), 2x 7800 gts, and an Antec True power 510 watt. Computer is prime 95 stable for 8 hours+. Survives loops of 3dmark05 all night but yet it still crashes at the randomest times. I would imagine if it was prime stable for so many hours and 3dmark05 stable for so many hours that it wouldn't die on me. Oh the ram also survived a complete loop of memtest.

I was happily playing CS:Source and then boom it decided it was time to crash, it wasn't a total system crash, just a application crash. I figure that might be a software issue.

The thing that worries me is after running 3dmark for a few hours when I was away for dinner I come back to a computer that is totally locked up.

What do you guys think is the problem? I never had any issues with my newcastle, but once I installed the x2 it has been all down hill from there. My guess is maybe its the psu? But another thing that worries me is the fact that so many people have had issues with the A8N-Sli Premium. Oh and yes I also tried running it at stock speeds but then it proceeded to lock up in serious sam 2. It seems to only freeze in programs that use all my system combined (cpu, gpus) as it survives individual component tests perfectly.

How is your cooling? When everything is running full blast, individual heat from each components is greater than running something that only stresses one component. Unless you have a billion fans and optical drives, you should be okay with the Truepower. You could always check your voltage rails with a $15 multimeter from Radioshack to see if it's dropping too low under a full load.

Also, you should try running extended tests on your CPU and Memory. A full night of Memtest86 and 24h of Prime95 would be good indications that it's not either of those. I've had CPUs fail at the 14h hour mark, something that wouldn't be caught if I had only done 8-12h.

Could it be the ram? Maybe the temps?

 

[OVerLoRDI]

the temps are all fine. I keep nvidia monitor when I game to take a look at temps and the cpu never rises above 51C and the graphics cards hit a little over 60C but thats it. My case definitely has enough cooling I would think, 5 x 80mm fans and 1 x 120mm. I'll do a long term test of the cpu and see what happens.

 

[aigomorla]

my first guess would be temps. second would be ram. Lastly, it could be software related, try a fresh install?

OHH i forgot to ask you, whats the voltage on your cpu??? Maybe your cpu isnt getting enough voltage. I tried to starve my system one time clocked at 2.6ghz but voltage at 1.3V and it didnt like that at all.

Hehe, i wanted a summer mode incase it got real hot for those of you guys wondering, and 2.6ghz at 1.3V imo is a better overclock then 2.8 at 1.48 :X

My voltage is at about 1.35. Do you guys think I need higher?

Try bumping up the voltage a little to see if that'll stop the random restarts.

Also try running memtest to see if your ram is the culprit

I bumped the voltage and im going for 24 hours of prime 95 on both cores. Wish me luck. The Vcore on the A8N SLi-Premium is pretty stable when the cpu is on full load. When the cpu is idle, thats when the vcore jumps around like mad. Just an observation for all the A8N-Sli premium haters.

If the cpu passes I'll go for 24 hours of memtest.

uhhh correct me if im wrong... ur overclocked at 2.5Ghz?? im guessing 10x250fsb and your starving your system at 1.35v? Definitely its a voltage problem.. id say try to bump it up a little.. to lets say 1.40 or 1.45 at least. 1.35 is stock voltage and overclocking from 2.0 -> 2.5 is going to require some increase in voltage.

So what vcore did you jump to? 1.40v?
