[SOLVED] Could I mix 2x4GB + 1x8GB RAM's?

[DanielSC]

Nowadays I have 2x4GB 2666mhz from Corsair and I would like to add more 1x8GB 2666mhz from Corsair too (getting 16 GB's), same voltage, speed, frequency, CL...

Mobo: Aorus z370 gaming 5 (4 ram slots)
CPU: i7 8700

Is there a problem if I make this "mixing", like would I have some problem in the dual channel from 2x4GB? Or it is okay ?

All help is appreciated!

Mixing memory is hit and miss , you won't know till you try them together.

Best to add another 2 x 4GB instead of a single 8GB, then both pairs will operate in dual channel mode.
