Quick overclocking question

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.

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.

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.

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.
