Gigabyte GA-Z77X-UD5H WIFI

[Benny0715]

Hi all,

I got GA-Z77X-UD5H WIFI last week for my new computer.

My comp spec is:
GA-Z77X-UD5H WIFI
Intel 3570K
Corsair Vengeance 1600 8G X 2
Vertex 4 128G
Evga GTX 570

My problem is I cant get channel B working, so I cant do Dual Channel. Im sure my memory is working fine, cox its working on Channel A which is Slot 1 & 3. I did try plug in one by one, but still Channel A(Slot 1 &3) is working, and none of the B(Slot 2 & 4) working.

Just want to see is there any tricks to make it work or Im having a DOA board, so i need to do RMA.

I have Corsair Vengeance 1866 16G x 4, full loading channel A + B with no problem.
Bios F7 ~
Did you update bios?

check for bent pin in the ram slots or dirt..the other place to check for a bent pin is under the cpu and the cpu itself. intel memory controller is built into the cpu now.
