F3-16000CL9D-4GBRH Compatibility

[HKfox]

Hi , i have a gskill F3-16000CL9D-4GBRH 2048MB X2 on a Gygabite GA-P55A UD4 and i5 750@4ghz .

I m looking for add more ram on my sytem .

Can i mix my actual ram with a kit F3-10666CL7D-4GBRH (2Gx2) or F3-12800CL7D-4GBRM (2Gx2) , maybe release the timing of the new one or lower my fr?quence ?

I have these settings for now :

Of the two you could try, no guarantees, the 1600 set would be the better to try, but best bet would be to go for a 2x4GB set which which would be less load on the MC, still provide 8GB and leave room for expansion......and with those two sticks (if you go 1600) you could try to pair up the 4 you have for 12GB...again no guarantees, but it's possible.

So actually, best bets, a 2x4GB set, the the same model F3-16000CL9D-4GBRH, then the other model you mention, the Ripjaws medium F3-12800CL7D-4GBRM, don't think I'd even try the CL7 1333s
