Mixing same model RAM with slightly different CL and MHz

[voiha]

Hello,

I am currious if it's a problem to mix ?

HyperX Predator, 8GB DDR4, 3000Mhz, CL15, 1.35v 
with
HyperX Predator, 8GB DDR4, 3200MHz, CL16, 1.35v

I already have the 3000Mhz version and I want another 8GB but I can get this deal for the 3200Mhz and I read kinda mixed information about this topic, most people says it's okay as long as the voltage is the same but still I wanted to ask, thanks in advance !!

You should always try to match the same ram together. That said it should work but with the frequency and timing of the lowest ram, 3000MHz CL15 in that case.

The important things are brand/model, speed, timings.

It's recommended to get as many attributes as close as possible.

 

In this case the CL16 is mostly due to it being 3200mhz. In theory it should work just fine.

its fine but the system will follow the slower ram.

I mixed Trident Z 3466 CL16 with 3200 CL16.

Applying XMP, it set both to 3200 automatically. Works without a single hiccup.

OCing the them to 3300MHz works, but I had to apply higher voltage.

Your mobo should set them to the frequency of the slowest stick when applying XMP and it should work normally.

 

Now to the CL issue.

A 3200 CL16 kit should be able to run 3000 CL15 easily.
