    I changed the CPU PLL to 1.57 and lowered the DRAM voltage to 2.04. I'll go to 2.02 if I don't get anymore blue screens. The sleep wake up problem does not seem to be there at lower FSB settings...OR...at least the last time I had the problem when I thought I had a stable system I had left CPU-Z running. I don't know if that could be the culprit. All I really know is that Vista was able to show me messages trying to start back up that I have never seen before and then I have to power down and the BIOS resets to 333 FSB!! I really don't want to break any speed records so what is a reasonable Vcore voltage? CPU-Z says the CPU is running at 1.34V under load at 8X445. Why is that so much lower that the Vcore I have in the BIOS (1.3875)?

    The system is stable a stock speeds and seems to wake up normally. This last time I had the problem I had left CPU-Z running. I don't know it that caused the problem but I sure saw a lot of new messages from Vista before it gave up and the BIOS reset the FSB to 333. I did change the CPU PLL voltage to 1.57 and lowered the DRAM voltage to 2.04. I'll go to 2.20 if there are no blue screens. There are no USB devices attached to this system.

    It's not much, with 1.25v CPU Voltage in BIOS under load my vcore is 1.168v, almost 0.1v less.

    Things are looking up. I have run OCCT for 10+ minutes at these setting and it looks pretty good. Whatever you guys told me to change seems to have done the job. The cpu temps max at 50C and the Vcore voltage hangs around 1.28V with a max of 1.30V. Thanks all, I really appreciate the speedy responses. My next questions are: Is the Vcore voltage still too high (1.36875V) for 3.6? 3.8?, Should I lower the ICH I/O and ICH Core to normal?

    All 4 cores at that temp? What are the idle temps and room temperature?

    I was going to attach all 4 graphs of the cpu temps but it looks like I can only do one attachment at a time? If not, a little guidance would be appreciated. Anyway, cpu 2, 3,and 4 run one or two degrees cooler. The room temp is a cool 65F and the case is a Lian Li P61 with all the fans running.

    Check posts by conners and acebmxer like the one acebmx linked.

    The big core voltage difference will go if you enable llc ,load line calibration.
    1.33 will be like 1.31 under load ,that kind of thing.
    Current Systems:

    Asrock p67 Extreme6.............. Gigabyte EP-45 UD3 ...................... Gigabyte 73 PVM S2
    Intel i5 2500k 4.8ghz................ Intel Q8400 3.8ghz......................... Intel D820 2.8ghz
    Zalman 10x cooler.................... Coolermaster V8............................ HP cooler
    8GB Gskill ripjaw ddr3.............. 4GB Gskill PI ddr2.......................... 4GB samsung ddr2
    60GB ssd/500GB HDD .............. WD 1TB hdd.................................... Seagate 160GB hdd
    GTX 460 1GB x2 SLI ................. Msi 9600GT 512MB(died) ........... Onboard gx
    Win7 64 ,750w psu(ocz)............ Win7 64 ,520w psu,seasonic...... Win XP pro ,400w psu

    HEC 6A34 case . ....................... Jeantec R2 case............................ Packard Bell case

    hoping to upgrade to http://www.thinkgeek.com/stuff/41/habicase.shtml
