    I just purchased 4GB G.Skill DDR2 1066 MHZ RAM and installed it into my motherboard (Gigabyte GA-MA78GM-S2H). I have tried fixing the problem by readjusting the vdimm voltage to 2.1 volts after reading on the G.Skill website that 2.1v is compatible with most motherboards. After doing so, I tried to change the settings in my BIOS to manual so i could reconfigure the RAM to a 1066 mhz option but the max still only shows as 800. Please help me out if you know any way i can change the frequency to the 1066 mhz my ram is actually supposed to be :).

    It really depends on what multipliers your board is capable of. It may not be possible to make it run at that speed. Increasing the CPU voltage will only shorten its life.

    What FSB speeds does the board and CPU support?

    The board supports a max FSB of 5200 MHz and my AMD Athlon 64x2 6000+ supports 2000 MHz FSB

    What CPU are you using?

    What speed is the CPU running at? It still depends if we can get even multiples to make 1066.

    200x4=800. So the FSB would have to be 266 for the memory to run at 1066.

    266x4=1066

    Will that be too high for my proc to run stable though?

    It may be. Can you lower the multiplier at all?

    What does the manual say about it? That is really the place to get all the best information.

    What make/model of board?

    You're not going to see much difference running the mem at 1066. I understand that you want the most your machine can (safely) supply, but did the manual say you could run 1066 memory at 1066?
