    Well I spent about 6 hours today going through various CPU Termination, MCH, and MCH Reference voltages and still no luck. I either get BSODs or after the first pass in LinX cores 0 and 1 would seem to "throttle" and then cores 2 and 3 would follow about 30 seconds after. I have no clue if that's the case or LinX would operate in a "lazy mans" mode to prevent errors and not stress the cores at full bore. When I get more time I may try again but until then I may just settle for my current overclock of 3.825ghz as I don't think 4ghz would be that much of a difference?

    Here's a video of what was happening.

    As I recall:
    • all required MCH Ref to be increased using Lsdme's procedure
    • some required CPU Ref to be increased
    • a few required Clock Skew changes

    Thanks for the replies guys. I think I'm going to stay at 3.825ghz though. I ran 3DMark 06 at 4ghz and I only got about 200 more points (Could be the 10.8 drivers). But either way it doesn't really seem worth all this trouble to get it stable. I may just try to fine tune this OC and tighten up my RAM timings as much as I can and call it the day.

    3.825ghz ~ 19010 marks
    4ghz ~ 19247 marks

    EDIT: These scores seem a bit low. I came across some old notes and I was breaking 22k at 3.91ghz.

    Many Q9550 overclocks settle for an everyday setup in the upper 3GHz range, even though they had stable settings up to 4.2GHz.
    Don't worry, be happy!

    If you want more help, post your current settings, and we'll advise.
