I have a problem and I thought maybe I ask here about it before sending the MB back to the vendor. The RAM slot 1 and 3 wont work. I have 2x4Gb DDR3 Kingston 1600Mhz and if I try to use any of these slots the PC starts beeping and keeps restarting few seconds after it starts. I tried 1 RAM at a time, the result is this: slot 2 and 4 work in any combination (single RAM stick or both), slot 1 and 3 will fail even if I use only 1 RAM stick. The problem is the slots are working dual channel 1 with 2 and 3 with 4, therefore 2 and 4 will not work dual channel. Is there a known issue about this? Thank you!
LE: the MB is Gygabyte B75M-D3H
