Can you mix 2400 with 2666

Solution
It can work together, there is a possibility, but when you pair both together, they run at the same speed. The 2666mhz would downclock to the 2400MHz speed since memory cannot run at different clocks.

But as other's have said, it's not guaranteed to work unless you know how to mess with timings and probably even sub timings.

Thanks a lot. I was tryin to figure it out I bought ADATA XPG GAMMIX D10 8GB (2 x 4GB) 288-Pin DDR4 SDRAM DDR4 2400 and was going to get some more but the price jumped up almost $50.
