    Default GA-MA785GT-UD3H Won't POST, 3 long and 1 short beep

    Hello,

    I'm trying to put together system and am getting 3 long beeps and 1 short beep during POST. No video but CPU Fan does power up. I searched online but all sites said 4 beeps meant "Bad Timer" and "System board needs to be sent in for repair".

    Here are the system specs:

    Giga-byte GA-MA785GT-UD3H (Rev 1.0)
    Athlon II X2 240 Retail
    OCZ 4GB DDR3 PC12800 (OCZ3G1600LV4GK)
    Thermaltake 420W (search for W0009R at newegg)
    Is the power supply sufficient for this setup? I would think so but just wanted to confirm. Is there anything else I can try? I did take the motherboard out of the case to remove the possibility of any short circuit.

    I have a 20 pin connector and a 4 pin connector and both are connected. The CPU as far as I can tell was locked into its place and the heat sink was also installed properly.

    Please help me!! I've put together few systems before but never had hiccup like this. It's possible that I got a DOA motherboard but then it does power up and I can also get the beeps from it.

    The memory is not supported. OCZ Ultimate Memory Configurator
    The Athlon II X2 240 Regor has a memory controller that only goes to DDR2&3 1066Mhz You may get it to 1333Mhz. This will take voltage and timing adjustments.

    ok, I found the source of the problem. It turned out that one of my RAM stick wasn't seated completely into the motherboard. After reseating it, it posted successfully.

    I had no idea that CPU controlled or limited the memory speed. I always thought that it was the motherboard that did that. I got the DDR3 1600 memory because I thought that I could get that speed by using this motherboard. Very deceiving! Why in the world do motherboard manufactures put memory specs if those specs are really controlled by what CPU is installed. They should at least mention that. I would also think that the CPU specifications on the box should have this specification. Happy that it works but not so happy when I forked 100 bucks for this motherboard.

    Thanks for your reply!

    If I had to guess it would be for overclocking the memory controller, and for future upgrades when the cpu's go to faster controllers.

    Same problem here. My new Gigabyte ma78gm-s2h motherboard only gave me 3 long and 1 short beeps. After pushing my ramsticks all the way down, things were hunky dory. So 3 long 1 short beep means "check ram again, genius!". It took some google searching to find this answer. I could not find three long, one short beep in any beep code overview. Much appreciated!
