Run Furmark in fullscreen in your native res with the amount of AA you usually use for ~2-5min depending on how patient you are.
Increase another 10mhz and repeat this process til you see artifacts, your computer locks up or reboots and drop the clocks back 5-10mhz (or start increasing voltage a tiny bit at a time)

Furmark is a horrible app to test true stability. It is a throttled app so it will never give you a true idea of maximum clock. I use Furmark as a quick look see, if it explodes or not, crossfire is working etc... but never for stability. Crysis 2, Heaven, etc or many times better and more accurate.

Considering 99% of cards can hit 1k core, I doubt you have a horrible overclocker and it likely could be a power *issue ignoring your cpu overclock.

Oh, had to figure out how to set it in my sig. I have adjusted it now. I'll also try Crysis 2 asap.

Crysis 2 doesnt stress as much as furmark or occt. And id rather quickly know if the PC is unstable, rather than spending perhaps 1min to 5 hours in a game in order to find out if the pc is unstable at current clock.

And not everyone has Crysis 2 (because its a POS console port)

No seriously do not waste your time on furmark. I can't believe people still don't know this. It's been unable to properly stress cards for a few generations now. OCCT did work up until throttling was added. To this date Crysis 1 + Metro 2033 on 99 loops remains the most accurate stress test.

Maybe you'll understand it from someone else...

@ tsm106, been playing some Bf3 for a while today and with 4xAA in CCC and Ultra settings in game, no motion blur tho I hate that. Running 1100/1500 1.174v at 5884x1080p res and getting 75-150fps. Usuallly around 100-120fps. Can't believe Rc11 runs so much better than all others. Bf3 looks insane in Eyefinity with Ultra settings and 4xAA. Unreal thumb.gif

Furmark is a focused program. it makes the card do the same thing over and over. it is totally unrealistic in that you will never see a game able to stress any card like it does, so it cannot be used as a proper tool for stress-testing.

Yet Prime95 for 12 hours is considered stable for cpu's where the average user would never stress their cpu like that. I get what your saying about furmark, occt vs. in game, but if you want a quick stabilty test then furmark and occt are the best choice.

99 loops, each test take like what? 1-2 minutes?

So 99 - 198 minutes? To see if a card is stable? HAHA

Guys, furmark and occt won't be a good test.... read this: http://www.legitreviews.com/article/1488/4/

(its for 6950/6970, but its the same with our cards...)
