These are my settings sir, I borked Vista messing with those lmao... I knew it was going to happen to. I am reinstalling it now.

Think you ar epushing ya rams way to far... Like Tony said P45 seems to have some issues with signal strengths with 2gb dimms to get them going the same way as eg X38/48... you are pushing for max speed etc... but are loosing stability big time with ya settings... I do it the other way around and prefer to get stability and then tweak which is far easier to do then to alter all subtimings and co : some quick pointers

AI Clock Twister: Stronger --> Try AUTO or Lighter here
AI Transaction Booster: Manual
Common Performance Level 9
Pull-In of CHA PH1: Enabled --> Disable all
Pull-In of CHA PH2: Enabled
Pull-In of CHA PH3: Enabled
Pull-In of CHA PH4: Enabled
Pull-In of CHB PH1: Enabled
Pull-In of CHB PH2: Enabled
Pull-In of CHB PH3: Enabled
Pull-In of CHB PH4: Enabled

CPU Clock Skew : AUTO
NB Clock Skew : AUTO

If stability is not increased try to mess with the ram skews... you cannot have it all...2gb dimms just don't clock as easy as 1Gb dimms... some peeps have good kits , mine top out around 1120mhz... awaiting the new Gskill PC9600 4gb kit...

I bumped my VTT up to 1.32 and my NB to 1.3, lowered my PLL to 1.54 and everything seems ok for the moment. Leeghoofd I have seen some things about the PLL voltage being set about 1.55 being dangerous is it safe to play around at 1.6?

With 45nm I would be easier on the voltages but even 1.7 is considered safe for 65nm but I stick with max 1.6 for 24/7 ops on 65nm... CPU VTT or FSB Term voltage is the so called dangerous setting for 45nm... They advise to stay below 1.4 at all times , for 65nm they support better higher volts so even there 1.4 is no prob... but if you can run it at eg 1.52 keep it there...

For 3.6ops try 1.45vcore then with the same settings might be needed to up some other voltage (PLL, FSB) try small first again to determine Vcore and then blend or co...

max PL Volt to E8400 on P5Q D...? i got Watercooling.

I use max 1.6 for daily use and 1.7 for benching... with some CPU's even 1.52 works fine for 550 FSB with some I need 1.6 already...
