I was thinking this instead.
4GB x 4 = 16
2GB x 2 = 4
20GB total.
Either way, I was off.
Most likely that setup (either actually) will run in dual channel, but it could run in triple too. If you can please report back here and tell me what it does as I'm curious. You wont really notice the difference anyways.
Even if it did get pushed RAM wise the difference in bandwidth wont be noticed real world sort of like my quad channel vs dual channel.
I'm not talking about size, but rather bandwidth. The difference between dual, triple, and quad channel on paper is huge but when simply using a system with a RAM setup of either one you can't really tell the difference at all.
