Hi, I'm Velo. I'm new. I have a ASUS P8H61- M/LE USB3 motherboard. When I first got it in March, I only had 1 stick of RAM that only worked on one channel(Channel_B) and not the other, at that time I thought I had to put my RAM in a certain channel which is Channel_B . Then Today, I got my Kingston 4GB 1333MHz 9-9-9-24-1T RAM today and I tried it with my other RAM which is a Wildstor 4GB 1333Mhz 9-9-9-9-24-1T RAM and the computer would turn on and everything with fans spinning but with a blank screen so then I tried both sticks of RAM seperatly in Channel_B, they work but when I tried both stick of ram seperatly in Channel_A, the computer won't boot. I only have 2 sockets to put the RAM in. What is going on? Should I RMA the motherboard, there is nothing in the manual about this. :S
