    This sin't exact science but close enough.
    If you read the SPD profile with SPDTool you'll see that the only thing that's given in cycles is the CAS latency, all other timings are given in time (nano/micro seconds.)
    The 5-5-5-15 timings for DDR-1066 may be already rounded up one cycle after calculation the number of cycles from the times given but it's still very close.
    if 4-4-4-12 won't work try 5-4-4-12

    Thanks a lot LSD, appreciated. Yes i'm getting lots of great help and making very good progress.

    I just finished a 1hr OCCT medium set test, no error, running cool. CPU never got over 49C running at 3.83 Ghz (426x9), memory on Auto,

    I know this is not fully tested after only an hour on OCCT, i'll test throughly over night.

    Here are 3 different memory test/benchmarks..

    Original..5-5-5-15 @ 3.6Ghz


    4-4-4-12 @ 3.6


    4-4-4-12 @ 3.83


    I assume the next step is to tweak the memory...

    EDIT: i had posted the wrong memory multiplier.. changed 2.66D to 2.00D

    Performance Level is sky high, auto us not a very good settings for it.
    I can't understand the hugh difference between the 3621MHz and 3834MHz benchmarks, was CPU Ratio the only thing you' changed other then vcore or did you set Statuc tRead to auto then too?
    BTW memory multiplier is 2.00D I assume.

    Right!! Set your tRD maually 15 is way high!!

    You can also safely set these if you like >>
    tRRD........................................... 3
    tWTR.......................................... 3
    tWR............................................ 4
    tRFC........................................... Leave auto for now, or set 52-54
    tRTP........................................... 3

    I was just running a test with tRead set to 8, booted ok but just failed, error on core 1, after about 15minutes on medium data set on OCCT.

    You are correct.. i changed tRead to auto between these two, is was on 8 i think.. so it went from 8 to 15 it would appear. and Yes i multiplier is 2.00D, i've updated my post.

    Better change one setting at a time.
    Try also 5-4-4-12 see if you can have it on 8 or even 7 and what results you get.

    Maybe one notch up MCH Core may help this. Check what is the DRAM Voltage in HWmonitor.

    Ok.. i'll run a number of tests, changing one at a time..

    I had already made the changes mentioned by LSD..

    tRead at 9

    tRRD........................................... 3
    tWTR.......................................... 3
    tWR............................................ 4
    tRFC........................................... auto
    tRTP........................................... 3



    I'll give this setup a wee test.. but also try tRead at 7 & 8 with 5-4-4-12

    I'll be busy for a bit!

    Thank you all very much.
