Is this a golden chip? (Q9550) - Page 3

post #21 of 77
Thread Starter 
I haven't had opportunity to find the best GTL for my chip... What if both pairs of cores like the same GTL reference voltage?

As far as I know, this is very rare... Just try it... Down your multi to take CPU speed out of the equation. Then try from 450FSB and up. Run Prime 95 Large FFT's for 6 - 12 hours.

Wouldnt blend be better as it puts more stress on the board?

Always thought that blend using ram & cpu would put the most stress on the boards FSB


Not really sure tho, could be wrong....

For overall system stability Blend is the best. And even though Prime 95 Large FFT's fail after 1 hour you system may never crash. But I believe that often, Blend will also show errors after some time, if Large FFT's are not stable.

Large FFT's is simply very good for testing FSB/Chipset stability when pushing those Quads

Yeah, wasnt really sure what isolated what.

I know I had my 9550 12+ hours small, and 25 passes IBT, but Blend was a pain in the arse.

Finally got it 12 hour blend by adjusting the MCH Ref on my UD3...

Nice chip!

I wish my E8400 could spawn two more cores and retain the same overclocking properties.

Small FFT's and IBT tests mostly the CPU. Blend is the most important for system stability.

I do 4.2 at the same voltage on my Q9650 E0, so indeed that is a terrible E0.

4.2GHz at 1.32v Load and Prime stable? If so, you have a golden chip there... My Q9650 needs 1.41v at full load for 4.2GHz in my P5Q-E to be Prime95 stable..

Well not quite 1.32, but I did 460*9 = 4120Mhz with a 1.30 in bios, under load its around 1.31v, but have changed some settings after that so now I'm at 467*9 = 4203, 1.35 in bios and 1.36 under load.

I'm sure that if i where to go back and find my old settings i could go down to about 1.33 now ( 467*9) but I've not bothered to.
