    I don't understand, where did you change it to 6 then?

    In the BIOS of course. the BIOS shows the information you enter at any given moment and the information that used to be there. My assumption was that after a boot it will update the previous information.

    See the screenshot of the same BIOS I have that I found on google:



    In addition I've tried to mess with other settings as LSD suggested but I got into a boot loop and I tried to restore them but now after I'ved benchmarked it I got the L2 cache at 5.1 instead of 4.7 :(

    EDIT: LSD suggested some speed tweaking but memset have different names form these values then the BIOS:

    rank write to read delay = 3
    Write to precharge delay = 6
    refresh to act delay 54
    read to precharge delay 3
    static tRead phase adjust =5
    command rate 2

    Oh no the defaults will remain the same, unless maybe you change multiplier or FSB.
    I wouldn't pay no attention to L1 and L2 benchmarks, the only thing they are good for is to show how reliable the benchmark is.
    L1 and L2 performance would not change with memory settings. L1 cache should scale liniary with CPU clock as it is non-blocking memory and operate at CPU clock, not sure about L2 cache.
    All advanced settings are on auto?

    All the other settings are on auto, e.g., Rank Write to Read Delay
    Write to Precharge Delay, Read to precharge Delay, Static tRead phase adjust, Command Rate.

    The only 2 settings I've manually changed were: tRead value = 6 and Refresh to ACT delay =50


    Memset:



    I wish I had the same L2 value of 4.7 rather then 5.8 now... guess it's more psychological

    What about these settings:
    tRRD........................................... 3 should work just fine, you have 5 now
    tWTR.......................................... 3-4 should work just fine, you have 8/13 now
    tWR............................................ 4-6 should work just fine, you have 12/17 now
    tRFC........................................... 48-54 should work just fine, you have 78 now
    tRTP........................................... 3 should work just fine, you have 7 now

    Can I change them from memset because I don't know how they are called in the bios. and the values there are very different.

    It was 4.7 before you changed tRFC. But I have mixed thoughts about the tRD=6, though latency and read are better, write and copy are worse.
    You can try 2.40B multiplier and see if you get better or at least same results.

    EDIT: try tRFC 58-68

    I changed the tRFC back to 58 and now the L2 cache is 4.7.
    Write and copy are worse but to what extent? I mean, can it really have a big impact on performance, that I should go back to tRead value of 7?
    (anyway I didn't test system stability with Prim95 for that value yet).

    The other values that LSD suggested, can they be tweaked via memset or BIOS only? I ask this since not only they are referred by different names in the BIOS, the settings are actually as LSD suggested in the BIOS, for example tRRD - I think is 3 already but is set to [Auto].

    You have to decide to yourself what's better as results are not definative. Try using MaxxMEM PreView and see how it is compare.
    I would go with the tRD 7 and auto settings and check stability, save a stable profile and then try to tweak more.
    I myself don't bother with advanced settings.

    Advanced timings on auto are probably set to 1.4425(577/400) x <value in JEDEC#1>:
    tRRD........................................... 5
    tWTR.......................................... 5
    tWR............................................ 9
    tRFC........................................... 78
    tRTP........................................... 5

    I used prim95 blended test with tRead6 and now 7 and I do get a hardware failiure.

    Here is a screenshot:



    Could it be due to incorrect setting of Prim85 or not enough voltage to some component?

    Did small FFT pass OK?
    I was sueprised your system boot at all :-) try +0.1v FSB and MCH OverVoltage for a start. What incremet steps these options have?

    Yesterday I ran the small FFT for 1 hour with tRead 7 and it passed.
    But even at the test before blended (between small FFT and blended - forgot the name) it failed.
    I raised the voltage of the CPU from 1.235 to 1.25v.

    Edit: MCH has 0.025-0.775v increments. and I gave it 0.05v. The FSB has 0.05-0.35v and I gave it 0.1v
