Concerning Dual Channel Memory


Nov 7, 2011
I have a 990XA board and a FX-4100 cpu, (8150 on the way), and 4 sticks of 2gb ram. I've noticed that my bios has Dual channel access disabled by default. I guess my question is why? Is it because I'm using more than two sticks? The mem I have supports Dual channel, but I'm not sure if it has to be in a two stick configuration. What would happen if I enabled the Dual Channel? Would performance increase or decrease? Right now, it's set to run at 1333. Would this have anything to do with it? Thanks in advance for answers.
