Windows 7: Quick overclocking question

beagrie07 · 09 Dec 2010

Just a quick question, when overclocking and looking for artifacts, if just 1 artifact is found over an hour, would the overclock be considered stable?

Thanks

Some would consider this a stable enough overclock, but I would err on the side of caution and back down your overclock by 5 MHz or even 10 MHz to ensure complete stability.

Leave it on for longer..overnight if at all possible...if it was mine I would'nt consider that stable...I do consider an O/C stable it it bench tests overnight for zero artifacts/errors w/e
So Wind it back a tad and run overnight

What he said. Artifacts can be caused by heat, and the longer you run, the hotter things get, and, well.....

Those aren't tears of joy

Most GPUs and CPUs can be overclocked given the right supporting hardware and care, some by quite a considerable amount. However, it only takes 1 out of the millions of transistors on the processor to cease working correctly at the higher frequency (and increased temperature as a result of the increased frequency) to cause problems such as this, even though the rest of them are working perfectly normally. The solution here, as I said previously, is to reduce the overclock by 5 MHz or 10 MHz.

How do you check for artifacts overnight. What if you blink? Is there an automated way of detecting them?

Thanks for replying, i've completed my overclock after testing clocks going and back down multiple times and checked for artifacts.

Got an Asus GTX 460 768MB.

Default:- Core: 700MHz, Memory 1840MHz, Shader: 1400MHz (Linked)
Overclocked:- Core: 840MHz, Memory 2100MHz, Shader: 1680MHz (Linked)
Idle Temperature: 31C (Fans on auto)
Increase: Around 14 FPS (I think!)

I wish I could of gone higher but artifacts kept occuring so thats why I thought i'd bring up a question.

I don't thisnk there's a program to look for them, it's just something you see. I could be wrong about the program though.

Well that's the trick about overclocking.... finding a safe zone with what you have. You seem to have found yours.

Good luck.

Graphics Card - Overclock

That will help you out.
That program will tell you if you get even the smallest artifact, and will tell you how long ago it happened.
