Small FFT test time?

post #1 of 23
Thread Starter 
Would an 8 hour small fft be enough to call a CPU stable?

I am going to bed in a few hours and already have 4 hours racked up... My PC is loud and colourful so it would be hard to sleep in here with it.

Ok then, as blend does everything. I will do an 8 hour + blend tommorrow and call it stable.

I mean after 8 hours of small fft surely the cpud has worked harder than it ever will.

Blend i shall use to check it in conjunction with my RAM which I need to oc up from 800Mhz 4-4-4-12

I think 950Mhz will work as i can use windows at 1100Mhz.

grunion, i wonder why you failed blend in a minute..

ram? lol.. that's so strange. small fft's stresses cpu like crazy, way more than blend.

Blend seems to me more like an 'overall' gauge of stability, while CPU stability seems inherently dependent on small fft

edit: and to answer the OP: I usually do about 6-8 hours small fft or an overnight run. I used to use blend, but it doesn't heat up as much. And I like to stress the p00p out of the cpu

i'd first run small, and then either run large then blend, or just blend after small. if you know you're CPU's stable, then run blend to see if something else isn't (like your ram)
