E6600 w/P5WDH black screen above 3.0GHz

[wstcoaster07]

When i OC my 6600 to 3.0 it works fine, yet when i go to 3.2 (400FSB 8multi) the screen stays black when i hit "save and exit". Any ideas why?

Just need some more info. What bios settings have u changed? Did you set your mem multiplier to 2? Also whats your vcore at?

got the computer to boot at 3.2 with fsb400 and mult to 8x by raising my vMCH a bit more. However, now when i run memtest my computer freeze completely. I just posted the issue in the general ocing thread:

http://forumz.tomshardware.com/hardware/Win-locks-running-MemTest-OCed-ftopict201983.html

here are my voltages:

vCore 1.525
vFSB 1.4
vMCH 1.6
vICH auto
vDIMM 2.2

pci freq 101
pc sync 33.3

did you lock your pci-e frequency? and that vcore is pretty high, higher than the safe zone i would say, what are your temps, what type of ram do you have? what is your cpu to ram ratio at?

 

[wstcoaster07]

lock my pci freq? Not sure what you mean but I set it to 101 (after seing someone elses post, but i think i will move it to 100 since it seems that is what more people use)

vCore: computer screen stays black if below 1.525

Memory: OCZ DDR2 800 plat rev2

cpu to ram ratio is 1:1 (running FSB at 400 and DDR2@800)

temps: idle-> 55c (taken from "coreTemp)
core temp also lists my Tcase at 85 (way too high right?) so I purchased 2 40mm fans to place on the north and south chipsets

You want it locked at 100, and I would bump up everything, especially your memory voltage, and then get a few cpu/mem tests together and start lowering things one at a time, until you have eliminated bumped voltages you don't need.

Did you use automatic memory timings? My setup refused to boot when I set the timings manually. But now I'm settled for running at 366 FSB, 9x multiplier (3.3 GHGz), this also required auto timings for memory

 

[wstcoaster07]

yea i am running auto timings (spd)

You may just have a bad OCer you know, its possible and shouldnt be ruled out. Still, an extra 600mhz is not too shabby and is more than enough power for a while, I mean you still got more power than an x6800.

EDIT: Also maybe you should change your sig to 3ghz not 3.2 since you havent got that far yet
