Ddr3 1600mhz and 2000mhz on the same motherboard at the same time? Tags: Memory DDR3 RAM Dual Channel Motherboards Last response: October 14, 2011 10:31 PM in Memory Share Ivanpg79 October 12, 2011 7:46:51 PM Hi. I was wondering if it works to put in dual channel memory at 1600MHz and a dual at 2000MHz in the motherboard. For exampel: 2*4GB RAM at 1600MHz + 2*4GB RAM at 2000MHZ in a Motherboard like Crosshair Formula IV. Can BIOS make the motherboard use the 2000MHz at it fullest and at the same time use the 1600MHz at it fullest capacity? Or do I have to downclock the 2000MHz>1600MHz?

Generally though it's best to use all matched RAM to avoid any possible issues. Ivanpg79 October 13, 2011 7:55:18 PM thnx Related resources RAM, Go for Timings or MHz?

It's worth noting that with DDR3 RAM especially, it is never recommended to mix RAM as often it simply will not function or will only function with errors. samuelspark a b V Motherboard October 14, 2011 5:51:12 PM You could try overclocking the 1600 to 2000 but even Bulldozer only supports 1866. altowyran October 14, 2011 10:31:41 PM hi there is putton at some asus mobos if u bush it u can use any ram at the same time with out any conflict ( search for it at ur mobo ( Can't find your answer ?
