I have 2x2GB ddr3 memory installed in my computer right now. I just bought 2x4GB memory today and I was wondering if it would be better to have a total of 12GB of memory or to run 8GBs of memory in dual channel. Which will give me more performance. The board has a total of 4 ram slots available.
I would run just the 8GB set and use the 4GB, as a backup plan. '
Typically, I don't recommend mixing RAM sticks to help prevent BSOD. Your two different RAMs have different timings (CAS Latency) and Voltage requirements. This doesn't make for a good comparing together!
