Hello! I've got today a new corsair memory stick, after I sold one to my uncle, who REALLY needed it. But, then I fired up my PC, started CPU-Z, and it tells me that I have only one RAM channel. I have two Corsair Value 512Mb sticks. Something that I didn't like about the new stick, is that is single sided, and my "old" one is double sided. Is that the main issue?? My mobo is a Biostar tforce 6100-939, and I have one RAM on the green slot, (aka DIMMA1) and the other on the other green slot (aka DIMMB1). I tried to change them, and no luck. Any advice would be well-taken. Thanks!!
