Stability Test

PaulyD said:
Agree on Rossi's thinking.

I have found I can get heaven stability quite quickly (Max all the settings) but usually need a couple of nudges on voltage to maintain it in games. The Sleeping Dogs benchmark (everything maxed out, hi-res pack) has become another test I do after heaven stability has been gained as I have failed this before when heaven has been stable. Run the benchmark a few times, do a 3d mark vantage and 11 and then game on.

Now running Heaven with settings as advised for an hour so far. Going to leave it for a few hours but I have to say I was quite impressed with 3D Mark 11 which found an instability with my 1150/1600 clocks after looping fine for 13-14 hours then crashing out to an orange screen with lines down it and a totally unresponsive PC.

So I recommend 3D Mark 11 in a loop for a lengthy but thorough stability test.
 
Last night ran Heaven for 17+ hours until I quit and ran 3D Mark 11 for 23+ hours until I quit the night before. My 7950 is stable at 1100/1500 and I only lost about 300 3D Marks and a few FPS in Heaven from the previous unstable 1150/1600

Some serious OCD :p
 
I run a few loops of heaven, then proceed straight to games. Bf3 or bfbc2 maxed out, the latter will soon expose any instabilities be they gpu or cpu.

I prefer to leave the benchmarks expose any instabilities which they will inevitably do if left for long enough.

Cannot be bothered starting up a session of BF3 with the possibility of it crashing out on me at some point.

That would just pee me off.
 
Believe me, the quickest crashes youll get on bf3 will be down to ea or server disconnects.:D

But i understand your use of extended testing. I can remember playing bfbc2, the only game ive played in recent years that would expose problems with 12 hour stable p95 small fft and blend tests, or 50 runs of IBT/LinX on an oc'd cpu.:)

I use Prime95 to test my CPU overclocks but wouldn't use for a GPU overclock as I find Heaven and 3D Mark 11 more to the point.

I tested this PC as Prime95 stable when I first built it after running an extended Prime95 run and now its passed extended runs in both Heaven and 3D Mark 11 which proves the GPU is OK.

I can understand why people don't like doing extended runs as its much more fun gaming and could take ages to find the optimal overclock.

I am not going to push mine any further as I have reached a happy medium and besides the difference between what is now my stable overclock and what was unstable is not very much at all.
 
I use p95 on cpu, but not IBT/LinX anymore, ivy bridge cpu's generate massive amounts of heat with theese. For gpu, heaven and 3dm followed by games. My 670 is stable in both at 1320/7586. But for games ive knocked them back a few mhz. Thankfully havent had any issues. Just a shame that the nv 670's are voltage locked, as i reckon this card could do a bit more with a volt increase.

Not even going to attempt increasing the voltage on my card and I don't know if its even possible.

I am getting a considerable increase in performance from default 950/1250 to 1100/1500 without increasing any voltage and am satisfied with that.

I have set Board Power (Power control settings) to 20 so I don't know if that increases voltage at all or in fact what that means.

Normally those things are a balance between low power and performance so I image youve basically put it on max performance :)

(That wont increase voltage, what it will do is disable any low-power-throttling i imagine)
