or u can use OCCT..it has also a good Memory test for VGA Cards an some other stuff...

But use the Tool carefully...It is on the GPU stress test harder then Furmark..But u only wanna test the ram tahts ok then..

BetA13 i have used OCCT memtest and it shows thousands of errors but in games that utilize almost all VRAM i have no problems so i dont know if this tool is reliable or not.
edit:My mistake no errors at all must have had my gpu overclocked when it showed all those errors.
Thanks

So it's OK to use OCCT for mem testing, It's not as stresfull as OCCT GPU testing?

I use to use OCCT for CPU, GPU and video mem testing. I'm not shure I'll do it again because of all the advices arround not to do it because of possible shortening the GPU life span.
And now nVidia recomends not to use FurMark any more so now I'm out of ideas for OC testing .

How are they testing the cards in production? It's no wonder some users have faulty cards if production testing is so "gentle" not to use torture test programs like OCCT

OCCT reports thousands of errors on my card too, without overclock, but I have haven't experienced errors in games so far.
Video Memory Stress Test reports 0 errors...
OCCT is a bit sensitive.

I stoped with OCCT tests because I get errors and my screen goes off on 830/1660/2000 (default V; full load temp. max 70C). With all other tests, FurMark, Kombustor, 3dmark, Heaven it's stable.

yesterday I tried 860/1720/2000 1025mV with kombustor, furmark, heaven and 3-4 hours of Clear Sky gameplay, temp under 70C, no errors.

I guess OCCT is not very good on my machine.

What do you think of Stalker Call of Prypiat bencmark:

should I bother with this one or not?

OC scanner has that "scanner" for artifacts which is maybe a useful feature?

well your screen went off because probably in OCCT the vrn on your card become to hot
after all those 70c is not VRM but the GPU itself and in a reference design GTX460 without
any VRM Heatsink those parts tend to become to Hot some times even more than 100c
(I have seen more than that )
Look at this picture it's a reference not overclocked GTX460 that show 101.8 on Vrm's

I have no experience with eVGA's OC Scanner....but eVGA Precision and MSI Afterburner are both just GUI's for RivaTuner...

Look at this picture it's a reference not overclocked GTX460 that show 101.8 on Vrm's

but it happens almost at the biggining of testing every time. and only OCCT.
I tryed OC scanner a while ago with 860/1720/2000, 1000mV. 30min. temps under 70C, no errors or artifacts.
Also if I'm not mistaken VRMs are in contact with cooler on gigabyte 460. Also I have 2 8x8cm vents blowing from the case side directly on the GPUs.
My old 260 had 4 temp sensors and one was for VRMs, I don't understand why they removed that :-(.
