    DRAM DRAM Voltage did not describe....


    I returned to the module 1x2GB(800 mhz in slot 2),
    2x2GB (1066) on slot 1 and 3 and increased
    MCH Core from 1.100V to 1.160V, and doing everything correctly so far ....
    Can you explain to me exactly, what I got with it?
    Can it happen to drop dead motherboard, processor or memory?

    Thank you in advance

    I don't know what is your ram moel so I can't say DRAM Voltage, the package or the sticker on the module should specify the voltage needed for 1066.

    (G)MCH(Graphics/Memory Controler Hub) is the northbridge which is connected to the memory and CPU.
    It transfer data from one to another. When you use more memory and/or higher speed memory it needs more voltage.
    Intel spec for the core voltage is up to a maximum of 1.21v, nothing is going to be burnt or damaged.

    I rigged with 1.100v MCH Core to 1.160v for now works fine,
    2x2GB @ 1066 slot 1 and 3
    1x2GB @ 800 slot 2

    Thnx mate...u 'r the man....
    I have KHX8500D2/2G @ 1066 mhz
    KHX8500D2/2G @ 1066 mhz
    KHX6400D2LL/2G @800mhz

    also have 2x1GB @ 667 but I did not try...

    I'm sorry that I wearied thee to questions ...
    Thanks again

    The KHX6400D2LL/2G can run DDR-800 with timings 4-4-4-12 at 1.95v.
    The KHX8500D2/2G needs 2.2-2.3v(verify with sticker) for DDR-1066.

    It's may be possible to run all 3 sticks at DDR-800 with timings 4-4-4-12 and 1.95v DRAM Voltage, if you wish to try it.

    Code:
    DRAM Performance Control
    Performance Enhance ------------------- : [Standard]  <<< Try Turbo for better performance
    System Memory Multiplier -------------- : [3.00A]
    RAM Timing Selectable ---------------- : [Manual]
    
    Standard Timing Control
    CAS Latency Time --------  5 ---------- : [4]
    tRCD --------------------  5 ---------- : [4]
    tRP ---------------------  5 ---------- : [4]
    tRAS -------------------- 15 ---------- : [12]
    
    DRAM
    DRAM Voltage ------------ 1.800V ------- : [1.96]
    Everything else as it is now.

    Therefore, the MCH core on 1.160v
    +
    what are now described

    just to remind you
    I do all three modules at 800 MHz without freezing, of course, when I changed the mch core 1.160v,
    the bios is that 5 5 5 18 now with no changes, with your changes that you will work faster

    Yes a bit faster, not much.
    Download MaxxMEM² - PreView, and run now and after the changes to see the difference, and lso the difference between standard and turbo.
