Solved ASUS P8P67 PRO MOBO and MEMORY Tags: Memory Asus RAM Last response: October 13, 2011 3:23 PM in Memory Share ami_subi August 16, 2011 9:31:10 PM Hi All, Regarding my new build with ASUS P8P67 mobo + i5-2500k Proc i have bought 4GB (2*2GB) G.Skill 1333 mhz RAM. Now i think that was not a wise decision and planning to buy some more RAM with it. So my question is if i buy RAM with different FSB (e.g, 1600 mhz or 2000mhz) will that work or i have to stick with 1333 like other chips? And if i order 1 stick of 4GB with the previous one to make it 8GB will that be fine or i have to go for again 2*2GB for consistency? Really appreciate any help. cheers, SM More about : asus p8p67 pro mobo memory ami_subi August 16, 2011 10:00:21 PM people any help on this!!! m 0 l abekl a b } Memory a b Ĉ ASUS August 17, 2011 1:10:36 AM You need to stick with 1333 speed memory. You can't mix and match memory speeds. You need to buy another pair of the same capacity, you can't mix and match capacities either. m 0 l Can't find your answer ? Ask !

Your entire mem will be running at the lower frequency , so with 2x2gh 1600mhz and 2x2gb at 1333 you will be running at the lower 1333 MHz .
