    Default GA-EX58-UD5 with 920 D0 @ 3.8GHz ?

    Hi<o:p></o:p>
    <o:p> </o:p>
    I have:<o:p></o:p>
    <o:p> </o:p>

    • GA-EX58-UD5 BIOS version f7
    • Core i7 920 D0
    • 3 x Corsair TR3X6G1600C9 2048MB 1600MHz 9-9-9-24

    <o:p> </o:p>
    Id appreciate suggestions for CMOS settings to achieve 3.8GHz and suggestions for moving that on to 4.0GHz.<o:p></o:p>
    <o:p> </o:p>
    I have another three Corsair TR3X6G1600C9 should these work in mobo with same settings?<o:p></o:p>

    Do i need to move to BIOS 9a?
    <o:p> </o:p>
    Thanks<o:p></o:p>

    So you want to use 12GB, right? Sorry just not sure what you meant about your additional ram comment there.

    I do suggest you use F9a BIOS

    Here is what I would advise for 3.8, hope your cooler can keep up. These are for only 6GB, was not sure what you meant. If you want to use 12GB you will need more IOH, QPI/Vtt, and Vdimm possibly as well. Please only use matched modules to save yourself from headaches


    0X00000050 << Incorrect Memory Timing/Freq or Uncore Multi
    0X00000124 << Incorrect QPI/Vtt Voltage (To Much/Not Enough)
    0X00000101 << Not enough Vcore Voltage


    You can either use 180x19 or 200x21, I will give 200 x21 for now as it is easier to set your ram up at stock that way

    Hi

    Thanks for that much appreciated.

    I have system running with 10+ hours Prime95 with Core temps <80c

    CPU Clock Ratio = 20x
    Turbo boost = Disabled
    BCLK = 191
    QPI = x36
    Uncore = x17
    Memory Multiplier = x8
    DRAM = 9-9-9-24-2T

    Vcore = 1.36250v
    QPI/VTT = 1.295v
    CPU PLL = 1.84v
    PCIE = 1.54v
    QPI PLL= 1.18v
    IOH Core = 1.24
    ICH I/O = 1.5v
    ICH Core 1.18v
    DRAM = 1.66v

    Have been to BCLK = 195 but Prime95 gave a hardware error after two hours.
    Have been to BCLK = 200 but Prime95 BSODs after a few minutes.

    So, very happy to have a stable 4GHz system and real hope it would go to at least 4.1GHz, thanks.

    Yes I do want to go to 12 GBytes of DRAM. What I have is three more Corsair sticks same part numbers as those supplied with PC.

    I put PC back the Optimum Defaults and installed DRAM, system booted fine. MemTest ran fine plus an hour of Prime95 giving it 10GByte.

    Tried to run the above BIOS config above but fails on boot with Overclocking voltage or frequency error.

    Tried putting QPI/VTT to 1.4v and DRAM to 1.68v but same problem.

    Changed:

    Memory Multiplier = x6
    Uncore = x13
    DRAM = 8-9-9-22-1T
    DRAM = 1.56v

    System boots and now two Hours into Prime95.

    Id appreciate any suggestions for getting DRAM up to DDR1600.

    Try Uncore x16 and x18, along with more QPI/vtt also. You may need up to or above 1.7 ram voltage for 12GB, just keep QPI/Vtt within a .5 range of QPI/Vtt if you go to 1.7 or above.

    Are you PM'n me at XS? Just wondering if you are the same user there asking about 12GB

    Hi

    Thanks for that, will give that a try when I’ve finished barbecue, not too many opportunities in the England this summer!

    No it’s not me that’s PMing you at XS.

    Hi

    Barbecue was great thanks. One thing my forty years in computers has taught me is with beer comes great clarity!

    Tried moving QPI/vtt and DRAM voltages up testing Uncore at x16/17/18 at each point. Got to QPI/vtt = 1.515 and DRAM = 1.72 but still would not boot to BIOS at this point fear set in!

    So decided to remove all DRAM and use the new set as 6GB and try and boot with my BCLK 191 x8 DRAM config, hung every time booting W7. Put original three sticks back and W7 boots, so new set has a problem. Trouble is it works fine as 6GB running with optimum defaults so I guess I’ll have trouble getting a refund.

    Interestingly MemTest shows my 191 x8 config has a memory bandwidth of 13,356 MB/s, the 191 x6 is only 9,436 MB/s so DD3 1600 is worth while even with extra latency.

    Guess I’ll have to try and find a 3 x 4GB solution.

    Thanks for your help much appreciated.

    Just asking what you need 12 GB of RAM for? Not sure you will see much of an improvement in anything. Why not just overclock the ones you have?

    One thing I have tested is that you will get a much better result if you loosen your timings and then overclock the memory - speed is better than tighter timings.

    Look at these pictures where I tested this. 1st picture is at rated speed and timings. 2nd is using 9-9-9-24 and overclocked as much as possible.
