Can i mix these RAM blocks?

[zeus444]

Hi there!

I don't know so much about RAM and I am uncertain whether or not I can mix these 2x2 blocks:

KHX1866C11D3P1K2 - I have 2 of these 4gb 1866 MHz blocks

CML8GX3M2A1600C9 - I also have 2 of these.

Is this possible?

i wouldn't if i were you.
one is made by kingston, while the other is made by corsair
one is 1866mhz and the other is 1600mhz

the differences are just too many
just don't

No harm done in trying 😀

As long as you have the Kingston modules running in duel channel and the Corsair ones in duel channel then there is theoretically no problem

Both can work on this same timings try and adjust in bios.

technically u can, but no guaranty it will work out of box (automatically),....
The rams will only runs as the lowest speed u have..

If you already have both I don't see why don't try it..

use the 1600 in slot 1-3 and 1866 in slot 2-4.. see if the mobo can auto detect/auto configure the ram..
if it's auto, then you are good to go.. (do some memtest86 if u wanna..)

Thank you all for answering, i will try in a couple of days when i have the opportunity.

My motherboard is the ASUS Z97-P, Socket-1150 if it matters

if it don't work u may need to setting the rams timing manually..

basic is look at the rams timing from kingstone and corsair, look at the 1600.. (1866 also have 1600 timing setting)
pick the slowest (biggest number) either it kingstone or corsair, use one of them in the setting, and test again..
