Hello Folks! Just built a new computer and decided to use my old RAM, at first it gave me a red DRAM light, but i pressed MemOK! And it seemed to fix the problem, thing is, i'm wanting to install new RAM at the moment i have an I5 2500 and overclocked it with Base clock to 4ghz. Now i'm wanting to upgrade my 6gb 1333mhz ram to 8gb 1600mhz ram. Will i have any boot problems, or issues installing new ram from a different brand and different speed? And should i also reset my BIOS to defaults and get ridd of the OC when i install the new RAM?
