Let me get this straight. My mobo can only handle dual channel memory. So, putting two (2) sets of dual channel memory in it would make it quad channel? And this will hurt my system? If I did do it is it going to be a pain in the ass? Do I need to reconfigure everything in BIOS?
I'm gonna be gaming mainly so I'm sure 8GB is plenty I just figured why not throw it in there so it doesn't collect dust.
Thanks for the answer guys!
Your memory controller is dual channel. That means that its only capable of reading/writing to one "bank" of two DIMMs at a time. If you have 4 DIMMs filled, then for all intents and purposes your memory controller must read data from 2 DIMMS, wait till the next clock cycle, and then read from the other two. In practice it's actually a great deal more complex than that, but you can see how having more DIMMs filled than you have memory channels available can measurably hurt your overall performance.
Since your memory controller (acutally built into your CPU die) cannot suddenly become quad-channel, you'll want to stick with a 2 DIMM configuration unless you're using so much RAM that your rig is starting to use your SSD/HDD for working threads. Even RAM that is running at reduced speeds is several orders of magnitude faster than SATA storage. My advice would be to try overclocking both sets and just use the one that you end up having the best luck with. You might be surprised to find that the 1600mhz kit actually OCs better. The silicon lottery is funny that way.
