How important is memory speed

Microsoft recommend 32Gb ram for MS2024 but no mention of ram speed which could be anything from 2133Mhz or more.

How important is the speed of the ram and what is the recommended minimum speed for 32Gb?

Thanks

Regards

In my experience all the way through flight sim, faster memory translated into noticeably improved performance.

I think if you're looking for DDR4 RAM these days most of what you'll find out there is going to be 3600MHz kits.

And don't forget CAS latency...3600 CL 18 would be middle of the road...lower CL means higher performance.

Hard agree - memory bandwidth is a function of speed AND latency. see: RamCalculator
