I am looking to upgrade my ram and I currently have 8gb (2x4gb) crucial tech. sticks of DDR3 PC3-10700 ram, and I cant find 2 more sticks of the same ram anywhere but I can find PC3-12800 sticks, they have the same voltage (1.5v) and I was wondering if there would be problems with this, or if the two different bandwidths would be a problem. (Note, I am new to computer hardware and things so go easy on me)
