Gigabyte EP45-UD3P and 4 sticks of OCZ 8500 DDR2

Okay, I have been here, and this also has more details about my system:

OCZ has not yet answered my question and my post has been hanging there since 12/23/2010.

I build my own computers but I have never had to change the voltage and speeds on my RAM in the BIOS before. So I'm a bit new at that angle.

I have 2 sticks of 2Gb OCZ OCZ2P10664GK that I've had for 18 months that have worked just fine.

I just bought 2 sticks of 2Gb OCZ2RPR10664GK. I thought they were identical but they are the "Reaper" model.

I can mix and match any 2 sticks. As soon as I put in 3 or 4 sticks, I get a BIOS alarm, blank screen, and it won't post.

I just updated my BIOS to the latest FFB version, here's a link to the actual download:

Can anybody help me change the settings in my BIOS to get all 8Gb of DDR2 online? This should not be this difficult, but it sounds normal on these forums. I mean, if I can't figure this out, normal newbs don't stand a chance, I've built 5 desktop computers and never had to worry about changing the voltage on my RAM.

  1. What alarm? Beeps? What beeps? What PSU do you have and all your system specs.
  2. BIOS alarm.. high pitched beeps upon power-on. No graphics output, cycles power, generally useless. If you don't know what a BIOS alarm is, should I trust you with DDR2 voltage? LoL

  3. RAM voltage is always equal across the board. It could very easily be a bad stick. Try using one or the other and seeing if it starts up.
  4. Uh, Daniel, most of us regulars have been around a while. We try to be obvious when we ask silly questions.

    Gigabyte motherboards can have problems running 4 sticks, even if they are all the same. Your problem shouldn't be too bad because they are all the same brand.

    Common memory BIOS beeps:
    Series of long beeps - serious memory problem, like none detected.
    Series of short beeps - nearly as serious. At the least, memory is detected, but it 's not working very well.

    Do all the factory specs of the different RAM modules match?


    Test each stick separately with memtest86+ to make sure each is working.

    Set the memory timing to that of the slower sticks.

    Remove any overclock until you get your system working.

    Make sure you are not overclocking your memory. Change the System Memory Multiplier from Auto to 2.0. You will see your memory clock freq change to 533 MHz.
    Note: Except for increasing instability, overclocking memory has little effect on a Core2 system:
    Note 2: Because of Note 1, DDR2-1066 RAM is largely wasted on a Core2 CPU with a 266 MHz FSB freq.

    Increase the RAM voltage up to a maximum of 2.2 volts.
