Mixing RAM speeds

[Torm]

Hi, I bought year ago two RAM sticks Kingston Predator 8GB 3000 MHz and now I got offer to get two more of the same sticks but clocked at 3200 MHz. MB supports dual channel (Gigabyte Z370 HD3P). Is there going to be an issue mixing those four sticks if I keep each pair in a different channel?

It should work, but no guarantee. Sticks will be running at lowest common speed though.

Even if they are in different channels? And is there a way to clock 3000 MHz RAMs to 3200? Although they are not certified to that speed?

Yes, because the memory controller can only run at one speed at a time.

 

Sure, you can try to overclock the slower sticks, but they might not run at that speed (e.g. no boot or unstable).

Perfect. Thank you for your reply. Now I just gotta find out if I can stick those RAMs under my CPU cooler.
