    4275MHz, 450 x 9.5



    The neg thing about this is having 900 ram at tRD 10. (2.40B runs out at about 1080 something.)

    With tRD 9, settings otherwise same, something like "WARNING: ILLEGAL CALCULATION, May indicate HARDWARE FAILURE Please read stress.txt No errors. 100 warnings."
    That means no tRD9 as I drop back to 2.0B and go straight to tRD10 for 450MHz
    Equally surprising though was passing just by raising tRD to 10.

    I seemed to run out of fps gains in FarCry2 at 4.1GHz. Maybe.

    Not very refined but there it is.

    Lower mem speed = higher tRD, unless you can tighten timings, mainly CAS. I'd think your memry could do 1080, with loossened advanced timings.
    BTW for me SpeedFan was showing 5c higher core temp compared to RealTemp and I had to give it -5 offest.

    I was expecting 450MHz to be difficult, perhaps because I've been reading that epic "Re: GA-EP45-UD3P - Won't boot with 450FSB" thread. Also, I'll probably chase higher soon, so thought I might as well change down the multiplier now.

    So I saved the 4275cpu/900ram profile, and sorted a 4275cpu/1080ram profile. Subtimings: tRD-9 tRFC-56 lots of 4, and a 7. MemSet says 1082
    Marginal improvement in SuperPi from 4250cpu, 11.123 to 11.029. Edit: 4275cpu/900ram 11.126

    Memory benchamark is more suitable for this kind of a achange. SuperPI is probably effected more by the latency and less by the bandwidth, still is 0.8 percent improvement.

    4.275GHz, 1080MHz ram.

    Slightly better than with 900MHz ram, as far as I can tell, for my hardware.



    I'm thinking the 2.00B figures would improve at 500 + fsb

    I'll try it Psycho101, in the interests of science.

    Is there a bios translation guide anywhere that lists alternate terms used for the same things in different bios?

    EDIT: Ok. I wasn't thinking clearly was I? 1125MHz! Obviously impossible?
    NEXT EDIT: Sorry, great Everest figures, but Prime fails immediately.

    Is it normal for latency (Everest) to decrease with higher clocks, or is it poss. to tune to roughly same latency for any clock?

    1080 seemed like a "sweet spot" for latency.

    Everest latencies are usually lower up to a point with higher memory speeds.
    See this post for a brief description of possible tRD settings when using the 2.00 system memory multiplier.

    With high quality 1066 DDR2 memory, speeds higher than 1100MHz are sometimes possible, but primary memory timings might need looser (numerically higher) settings.
    These looser settings will negate some memory performance gains.

    I know there'll be a point soon where the 2.00 divider becomes mandatory, but even at this point 900 does not perform as well as 1090 for my hardware.

    1125MHz gave instant "hardware failure" in Prime95.

    Seriously thinking of buying 1100 G-Skill and giving Corsair to son.

    GA-X48-DQ6, E8500, 2x2 GB Corsair Ram



    The initial +.2 MCH was to get the 4 GB of ram to boot with this mobo.
