Mixing memory

[lfforte_35]

Hello,
I have 4GB of G.skill F3-12800 CL8D memory installed on my Asus P7P55DE pro board. I ordered another 4GB of the F3-10666 CL8D memory by mistake. Can I run 12800 CL8D combined with the 10666 CL8D?

Yes. You may need to adjust memory timings to the lower apec memory, though.
