The title says it all, I have just recently bought pieces ( RAM= 2x4Gb of Vengeance LPX 2666 MHz) to make a gaming PC and I have tried msconfig, everything I could find to try and fix this problem but couldn't... Do I need to update something? And it also says that my memory is in single channel ( I have an Asrock AB350M Micro-Atx board that supports dual-channel memory and only has two ram slots). Somebody help me!
