Having instability with my 4800mhz ram I got for my Ryzen FW 13, so I'm just gonna get new ram. Hurts the wallet though, so how much would it impact performance to have this latency difference?

~ 2,14ns difference from the CAS alone. Other timings are also shorter.

Given that total memory latency is often above 80ns not that much of a difference. And that assumes that AMD supports CL40 5600 Jedec. At least those Dimms should also support CL46 5600 Jedec, so that they should still work either way...

Would you mind passing the source on this? If so I'm not even gonna price track the CL40 kit.
