EVGA SLI GTX580 Classified Ultra benchmark/stress test

Hi all,

I've built a beast of a machine here at work for a developer with a dual processed EVGA SR-2 with 2 x overclocked Xeons along with EVGA SLI GTX580 Classified Ultra's in SLI, and whilst I'm able to check the overclock of the CPU's (running at 4.2Ghz), I'm also wanting to stress test the SLI setup of the cards as well to check case temperatures when the whole thing's under load.

I've tried Furmark, but unfortunately it only seems to load up 1 GPU, and I think it uses a bunch of CPU as well. Can anyone recommend something that will either a) load up the entire system (CPU's and GPU's all at once), or b) Just load up both video cards so I can continue to run Prime95/Intel Burn Test on the CPU's whilst it hits the graphics cards.

As usual, many thanks in advance. :)

Furmark should definitely be capable of loading up both GPUs... I've used it to stress test my GTX480s loads of times.

The traditional "full load/power test" involves running Furmark alongside IBT.

Oh and BTW, I ran BF3 on it "for stress testing purposes only" ;) and was *only* able to get on average 65fps with EVERYTHING maxed out/Ultra, including 4XMSAA, Ambient occlusion etc etc @ 2560 x 1600 on a Dell 30" monitor. CPU's didn't break a sweat, but talk about an intensely GPU intensive game! :eek: :eek: :eek:

How do you configure Furmark to do it though? In looking at the EVGA precision software it appears it's only using 1 x GPU... or do you set up the NVIDIA control panel to do something special with Furmark.exe?

Ah yes - that was introduced with the 5-series (I'm using GTX480s)

That shouldn't stop you using both GPUs, but it will stop furmark stressing your GPUs to 100%. Review sites tend to use high-intensity games to test power draw these days (e.g. anandtech use metro 2033).

Hmmmm, seems anything I run that tries to hit the GPU also requires CPU as well - so when I'm running 100% on GPU's and I try and use Prime/IBT the GPU load drops off. Anyone know of an application that will stress the whole system (CPU + GPU) at the same time?

Run IBT while running Heaven benchmark on max (AA etc).

See what the load percentages are then :---)
