Gigabyte GA-890GPA-UD3H RAM issues Black Edition

  1. Hi there all...

    Iv got a problem with my new Black Edition RAM from AMD
    OCZ PC3-12800 AMD Black 2x2GB OCZ3BE1600C8LV4GK
    timings are 8,8,8, 24 1600MHz @ 1.65

    Motherboard is Gigabyte GA-890GPA-UD3h

    Out of the box both DIMMS plugged do not work. One DIMM with all ram settings in the bios set to "auto" will work in any DIMM slot.

    THe second DIMM will not work by itself in any DIMM slot at settings set to "auto"

    If i install the one DIMM that works i change the Voltage only and increase to 1.65V THEN both DIMMS installed will work. I then have to increase the voltage .1 at a time to increase the speed. both DIMMS runing @ 1.68v 1333MHz

    Question 1 - Why do i have to increase the voltage for the RAM in order to make both sticks work?

    Question 2 - Why does the one specific DIMM not work by itself but when paired with the other one it does.?

    Sorry for the long post but any help or insight would be greatly appreciated

    Thanks all.

    That is not an uncommon problem... From our experience, they are designed to work that way on some motherboards.
    What did the Gigabyte site tell you about that board and its idiosyncracies?

    i thought it was a RAM problem, being that one DIMM would not work without the other.

    Maybe i should contact gigabyte.

    Thanks for the reply

    I want to build the fowolling system
    However i would like to change the
    for a dominator ram model.

    I would like the model to contain the same 1600MHz speed, latency and space.

    I have £100 to spend, can you recommend one?
