    Alright then, I have everything changed to how you've suggested, but I'm still having those weird issues of slower framerates in Crysis. Before I get to that, I thought you might like to see this:


    Anyway, those Crysis benchmarks. (They all add up to a lot, so I had to use pastebin.)

    This was my "best" run. 266 FSB x 10.5 with CPU & PCI Express clock drives on 700 mV, EIST and C1E both disabled. Everything else was set to optimal.

    I then ran it 3 seperate times using your settings, getting totally different results each time.

    Run 1:

    Run 2:

    kornfan71 private pastebin - collaborative debugging tool

    I'm not sure how I got minimums of 0.80 FPS on the last 2 loops there....

    Run 3:

    Any reason I get such different results? But more importantly, why is 2.8 GHz is faster?

    Hmmm, I have no clue, but with Average Tri/Sec: -23014982, Tri/Frame: -1395695 (negative numbers,) should this benchmark be trusted at all?

    EDIT: consider 400FSBx7.5 (2,66D multiolier) for superior memory performance.

    I'll get on that and get back to you later. I think I might try to tighten my RAM timings to 5-5-5-15 also, since that's how they're rated.

    Why how are they timed now? Ignore what BIOS shows you, see in MemSet.

    CPU-Z is showing timings of 5-7-7-20, unless I'm incorrect. BIOS is set to "Auto" but shows 5-5-5-15 (it's probably not right)....



    I have yet to really test these new settings (400 FSB), so I'll have to post later.

    Ignore what you see in BIOS, CPU-Z shows the actual applied settings.
    It seems to me that XMP profile is disabled, I would have expect timings would be 5-5-5-15 in CPU-Z if profile1 or auto were selected. Perheps Turbo is on?
    Use MemSet screen capture for memory settings as it has more details.

    Alright. So, I ran those benchmarks again and got this:

    kornfan71 private pastebin - collaborative debugging tool

    I only look at the Min Max and Avg framerates. This one is the most consistent of all of the overclocked, and the values aren't too far off from the best run I had.

    And here's the screen you wanted.

    When I see a benchmark that have such results for some of the measurments I tend not to trust anything it shows. Why should I think the other measurements are accurate?

    Point taken. But they are a rough ballpark estimate. If I just run the game normally with the FPS displayed, I get roughly the same values (they aren't quite so low since I don't run around with grenades and RPGs like in the CPU benchmark).

    Anyway, what should I do with those RAM timings? I would assume that I should just time them 5-5-5-15?

    BTW, it's on Standard, not Turbo, and the XMP is "Auto," so it could be disabled.

    I see, try profile1, this should set the standard timings right.
