GTX275 & Furmark Over****ing

GTX275 & Furmark Overclocking!

As above chaps, it's regarding using Furmark to check my overclocking is stable. I have never really used a program to check for stabiity and just run Crysis & Warhead as it normaly find a unstabe OC within seconds.

Now what i need to know, how long do i need to leave Furmark running before i can say it's stabe? Also, what are safe temps for this card when overclockng?

I have set it to...

640x480

stabiity test

not fulscreen.

Cheers chaps

Methinks you're missing an L.

Lmfao Can a mod please edit the title cheers

Haha. Id say running a full test should be enough to find a unstable overclock. You could use something like ATi Tool

 

[Freak]

cant remember but there is a burn in, extreme settign or summat like that

Not sure whats going on here but so far i have...

Core - 700

shader -1465

memory 1200

Now for some reason i'm strugging to go over 700 and i'm not sure what the issue is. I can set say 720 on the core in rivatuner click appy then when i go back it's reverted back to 700? any ideas? driver issue maybe?

The card is an Asus GTX275

Also, i can not get the shaders any higher without a BSOD, surely they shoud go higher?

I saw on a magazine which talk abouts nvidia geform that stress the gpu

Your getting better clocks than me. Using an Asus GTX275, watercooled, and goes unstable after abour 685 on the core. Can get the memory running a bit faster though.

But like somebody else said, I use ati tool and its a nice easy way to test.

Well i managed to get 720 on the core last night which was 100% stable and i'm sure there is more to go. The shaders have left me confused as when i go higher than 1465 it fails, i remember my GTX260 shaders going a fair bit more than reference.

What do you have your memory at? I sort of settled with 1200 as i never really ike pushing the GFX memory on my cards.

Cheers by the way everybody else.
