Hello guys. I just build my own pc with 1x8go ram corsair 3000mhz 1.35v cl16 and i enabeld xmp and set the speed to 2666mhz and latency down it self auto to cl15 and voltage to 1.20 (i didnt toutch voltage)after few weeks i bought another 8go ram corsair 2666mhz 1.20v cl16 (still on transit) my question is that will effect compatiblity even both using 2666mhz and the 3000mhz will up it self to cl16 to match the other one ? and i will getting less fps than using same rams? and should i disable xmp after installing the new one. Thanks for understanding my english still improving it.
