AM4 - M.2 Slot Question
11 minutes ago, Hi P said:1.- Most AM4 mobos only support NVMe 3.0 x4 on the M.2 slot that uses the CPU PCIe lanes, never available on the M.2 slot that uses the chipset, why is that?
because chipset M.2 slots share bandwidth to the CPU with other stuff on the chipset, say ethernet, USB etc. There's no spare bandwidth for a PCIe 3.0 x4.

2.- What would be the difference between placing a SATA SSD on the M.2 slot from the chipset vs the M.2 slot from the CPU?
A little bit of improvement in latency (expressed in numbers) in theory since the connection is more 'direct', but the difference is too small to even measure.

3.- Can you boot the OS from the chipset M.2 slot? or only from the CPU M.2 slot?
Both of your choice.

chipset also gets pcie3
