    Heh, that is a good ideea, but didn't really need it so far as I have a good memory with numbers.
    But still I just don't get it how I got to that 500x7.5 that easy, but 500x8 or 445x9 is such a dead end.

    Yeah, my cooler is a old Zalman CNPS 7000C-CU. I've had it for over 5 years now. It did a superb job cooling my old Barton 2500+ @2400MHz, but maybe it's time for a change. Although I just may try lapping it before buying a new cooler. That 700g+ of copper should be able to cool more I think.

    A spreadsheet with all possible combo's of voltages has proved invaluable to me. print it off and tick as you go. If I'd have saved the thing I could have posted it here, however I formatted mt HDD a month or so ago and it turns out my sheets were on the disk rather than on my USB stick, which was annoying.

    Unfortunately lapping your Zalman won't benefut you much, if any. Although it's made of copper, it's an old design and doesn't have the surface area needed to perform like todays enthusiast grade HSF's. It's a good cooler for stock or a light OC though, up to about 3.6Ghz on a dual core I'd say. If you get a new HSF, definately save the Zalman for another project.

    I know, it was a great cooler back in the days. But still, I'm pretty good with 64C on each core and 57-58C max cpu temp, as long as I get that 4GHz stable. And this is with 27-28C room temp. I'm not aiming for anything higher, for now. Maybe just for testing.

    LE: my previous settings with 1.35V LLC Disabled resulted in a restart after 15 minutes of blending. So i disabled LLC, and upped vcore to 1.375V. So far I'm 32 minutes stable, the longest I've got so far with the below settings. My E0 seems to be a real voltage hog.

    I don't need to lower my Refs till I hit 500FSB usually. However, his CPU Term and MCH Core are low for a 445 bus. Like they've said, start with a touch of vCore, then add a little vTerm, then maybe a bit of MCH Core... shoot, what'd it take, Psycho, 2 months for me to get my first stable build? Regardless, you can win with looser timings then tighten them up later. For that matter, put your RAM in Auto and worry about voltages first, till you get the hang of things.

    Oh, and Stable means 20+ hours Prime minimum. That's a lot of rebooting.

    I know, 24 hours it's what I'm aiming for. Right now I'm 15 minutes left to 1 hour. The first sattisfying result in over a week. I'll let it run over night and see what happens.

    It took a while grish, but all came together in the end. I think you've got an exceptional result, especially with 8GB of RAM. It's strengthened my opinion on GSkill too. If I were to be asked to build a PC with 8GB I'd be happy to use those sticks in a UD3P/R, maybe even a vanilla UD3, or the "lite" version (UD3LR or something). All the E8xxx regulars seem to have had good results, Grishkafool, Dan-W and Boombasticsloth among others. Boombasticsloth did so well he bought another E8xxx for his work PC and got an even better result!

    Morph, for sake of elimination would you be willing to either decrease FSB and increase CPU multi with a 2.00D/B RAM multi, or try 6-6-6-24 timings to definately rule out RAM issues? If the settings you're testing now prove unstable that is.
