Hey all, new to the forum and am trying to get some advice
I have recently upgraded to the q9550 since the price drop and am having a hell of a time trying to overclock it!
I have my c2d oc'd no problem but, this quad is giving me hell.
I have had an especially hard time finding someone with the DFI P35 and the Q9550 to give me some advice so maybe if someone here has successfully overclocked the q9xxx on this board and has some setting to try that would be great!!
My problem is that I cannot get more than two cores stable at the same time, trying to get all four has proven to be very difficult. I have gotten to 3400mhz at 3hrs prime stable but, no more than that; after about hour three cores 2 and 3 crash.
I have adequate colling on the NB and the pwm area, and a watercooling setup dedicated to the CPU so cooling isn't an issue, I have even cranked the volts up to 1.4 and have not seen over 58c under full load in prime if that is any help.
Any and all advice is much appreciated
EDIT: Here's my settings for reference
Here are the settings that I can get 3hrs prime stable, after that cores 2 and 3 fail:
