ok im at 3.6ghz 424*8.5 w/1.38v. i had to put up my fsb voltage control to +.1v
and my mch voltage contral to +.3v its the max, is this save or im i pushing the board to hard? my q9450 didnt need any extra voltage 1.36v 3.2ghz. is it my chip or my board?

Possibly. See this thread.

E0 / 400 * 8.5 (3.4) / Vcore 1.300 and don't believe my board supports LLC/Vdroop control.

Using a stock cooler, I ordered a different one but kinda ****ed it up (long story) so I'll get around to replacing it soon. Temps are 32 at idle (one core stuck at 38) and about 65-70 under prime.

Get me in this club.

Mines currently at 3.84ghz (450FSB with the little asus kick the Rampage does) at 1.325vcore 1081mhz DDR2 8GB etc.

I have had mine at 3.92ghz but I was unable to get her completely stable in the little time I messed with it. I might try again or go for a full 4ghz here soon this January.

You're in!

Got another UD3P and im back to OCing it.

My C1 seems to be stable @ 4 ghz @ 1.36Vcore in bios, i ran it for 90 minutes. Now I am trying 1.39Vcore @ 4.1 Ghz.

http://valid.canardpc.com/show_oc.php?id=474411 --> that's with 150ps of skew

@error10, what's the range for CPU pll/termination and reference? ET6 has it @ 1.85/1.6/.76

I am not trying to leech or anything, I am trying to find what are safe limits for those settings. Apparently those high settings is worse than overvolting. I'll probably have the stress test screenie by tmrw

Hang on I have to dig it all up.

PLL is 1.5V ±5% on the Q9550. The 1.8V the board puts in by default is severe overvolting and should be manually corrected. I did.
FSB Termination is 1.2V ±5% on the P45.
NB reference is as high as you need to go to make it work. (Could be anywhere from 60-75% of NB voltage.)

Thanks, THAT was what i needed to know. Cuz i looked at it the PLL and i heard that 1.7V was overvolting and the board defaults it @ 1.85!

Thanks a bunch.

I was just checking around, is mine considered one of the better Q9550s C1s?
