    Hi Everyone.

    I hope I can make this as clear as possible but but I bought some 2GB 1066Mhz Hyper X Memory & Clocked it in my bios to 533Mhz in the Dram profile and changed the operating voltage to 2.00 volts.

    The motherboard that I have is a asus M4A78-VM with latest bios updates.

    The problem that I had when I done this is I turned on my pc & was not able to get the post beeps nor did anything come up on the screen so I took out one of the sticks and left one in and put a 1GB PC2 1gb 800mhz memory stick in and it worked.

    Then i pluged back in the 2gb kingston stick after clearing the cmos settings and then got the post beeps but in the bios only showed 2046 memory installed and in windows it shows 4gb of memory installed so i am confussed to wheather one of the memory sticks is fried or not.......................PLEASE HELP :):eek:

    So to be sure, you reset cmos and set bios to defaults ?

    You have 3gb installed, windows says 4gb.

    As you booted into windows and its showing a large amount of memory i doubt its fried, however something doesnt sound right. I would run memtest x86 to see if any of your ram is bad. The fact that you are using 2 sticks of ram that are rated at different speeds probably is not helping either. DDR2 runs better when using matched pairs, otherwise you get issues. Some Gigabyte boards allow differently rated ram but they run in something called "Flex mode".

    My advice , run memtest and if your ram comes up ok then just use the 2gb stick until you can get another to match it. :D

    Also, i would'nt being upping the voltage to 2.0 volts unless you really have to. Voltage should be raised slowly, cpu and ram are very sensitive to voltage and the resulting heat produced. :)

    First thing to check is that you have the latest bios for your MB
    Second - In your bios make sure the "Memory clock Mode" is set to auto.
    Third - In your bios make sure the "Memory overvoltage" is set to auto.

    Your MB should support 2GB 1066Mhz Hyper X Memory. The above settings are set by default normally to ensure satifactory working of the memory modules and the motherboard.
    Also note that DDR2 1066 is supported by AM2+ / AM3 CPU only. The default DIMM frequency depends on its Serial Presence Detect (SPD), which is the
    standard way of accessing information from a memory module.
    Is your CPU AM2 - if so i dont think DDR2 1066 is supported by your MB.

    I hope the above info is useful.

    Kind Regards

    Basically thats it, wont hurt to run tests on the other stick at some point too. Its worth remembering that just because your ram can handle 1066 doesnt mean wack it straight up to that setting. A slow increase is better that way you find a good setting. Also clock settings affect other things in bios. Do a bit of research into overclocking to be safe.
