    Default GA-7PESH3 Memory problem


    I hope someone can help me.

    I just finished building a high end PC workstation using the GA 7Pesh3 motherboard. The problem is that the board will only boot using 64Gb of memory and not the full 128Gb.

    The memory I have is 8 x Samsung DDR3 1600 16Gb ECC/Registered (M393B2G70QH0 - YK0)

    • Mfr Part Number: M393B2G70QH0-YK0
    • Type: DDR3
    • Capacity: 16GB
    • Speed: PC12800 1600MHz
    • Size & Bit: 1G x 4
    • Pins: 240pin
    • ECC: Yes
    • Registered: Yes
    • Chip: Samsung
    • CL 11, 1.35V

    Full details of your computer would be helpful.

    What CPU are you using? If you are using an E5-1600 Processor, I believe you won't see half of your RAM (see the 2nd link below, the bottom table on that page).

    I found a couple of tables on the GA website that explain what type of RAM will be recognized when depending on processor, although I don't know if that will help.

    It seems I am having memory problems with my new gigabyte 7pesh3 motherboard. I am building a new system. Kingston 16GB 1600 ecc rdimm (KVR16R11S8K4/16), onboard video until I get system installed, ssd 256GB HD, a single E5 2620 v2 2.1Ghz (second in the mail).

    Initial start up brought me to the bios. All looked good so I saved and exit. Since then it starts to no bios, and two red led are lit on the motherboard. The motherboard chirps a consistent chirp (not beep). Having a hard time finding info on the red leds and the chirping sound. One forum suggested bad ram :(

    Any help would be greatly appreciated,
    thank you
