How much better is cl46 than cl40 for 5600mhz RAM? (alien.top)

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?

CL40 is better than CL46. CL stands for CAS Latency, or Column Access Strobe Latency: lower is better.

That being said, I have yet to see any head-to-head comparison between 5600 CL46 and 5600 CL40 kits. My assumption is that it would be minor in most cases. The primary performance benefit to higher-frequency (and therefore higher-bandwidth) RAM is iGPU performance. I wouldn't expect that to be terribly latency-sensitive.

Out of interest do we know what CAS the Framework branded RAM is?

CL46 I believe.
