Hey guys,

I've recently bought the Asrock X570 Taichi which has 3 NVMe slots, now are these driven from the X570 chipset or are they controlled from the CPU?

In other words, do I need a 3xxx series CPU to use these or will a 2xxx CPU work 100% with the 3 drives?

Thanks :)

Hey, with a 2000 series CPUs two M.2 slots will work at Gen 4x4, while the first M.2 slot will work at Gen 3x4. https://www.asrock.com/mb/AMD/X570 Taichi/#Specification

You can look on the motherboard manufacturers page for the board. Under storage specifications.

Thanks, so this is gen 3?

It does say that, but the cpu uses 4 lanes to communicate with the chipset. It'd be 4 gen 4 lanes on Zen 2 vs 4 gen 3 lanes on Zen+. So there isn't the bandwidth there to run the drives at gen 4 speeds.

Interesting, doesn't the M.2 module communicate at 4x4 speeds with the memory modules or other 4x4 devices through the chipset independently from the CPU?
Why would data go directly from the SSD to the CPU?
