i think its pretty stable cause ive ran IBT through 20times set to high
and ive read that, doing so is equivalent to running your computer for 3 days.

No...

20 runs of LinX/IntelBurn doesn't determine 24/7 stability in the slightest. The only thing it determines is that your CPU was stable for those 20 passes (just over an hour or so)

Who's to say that it doesn't crash after that hour? or even worse, crash while you are doing something important with less CPU utilisation.

To get a better judgement of overall 24/7 stability you want to be stressing the CPU far longer AND be using more than one method of stress testing too.

This is what I and many others here would consider a 24/7 stable overclock.

Prime95:

12 - 24 hours of Small FFT's
12 - 24 hours of In-Place Large FFT's
12 - 24 hours Blend

LinX/IntelBurn (With the latest Linpack Libraries):

100 runs using the maximum available RAM with nothing running in the background. (This is includes disabling various Windows services such as Windows Update and shutting down any Anti-Virus monitoring software.

Memtestx86+:

10 passes or a 24 hour run

MemTest:

Setting to run with the maximum available RAM with no background processes running (see above)

If your system can pass every single one of those tests then you are looking at a true 100% stable overclock, and there is a good chance it will be. If it can't then it's almost certainly unstable somewhere and there's no two ways about that.

I'd rather know that my system isn't going to crash than actually have it happen when I least expect it, just because I thought it was stable.
