Question What is the max speed of Crucial P5 Plus 2TB PCIe Gen4?

[MalcolmKK]

Hi All,
I hope you are well.
I have two of these M.2 NVMes.
Model serial is: CT2000P5PSSD8

The ASUS motherboard spec says this:

Supports 2 x M.2 slots and 8 x SATA 6Gb/s ports

AMD Ryzen™ 5000 Series/ 3000 Series Desktop Processors:
M.2_1 slot (Key M), type 2242/2260/2280/22110 (supports PCIe 4.0 x4 & SATA modes)

AMD Ryzen™ 5000 G-Series/4000 G-Series/ 3000 G-Series/ 2000 G-Series/2000 Series Processor
M.2_1 slot (Key M), type 2242/2260/2280/22110 (supports PCIe 3.0 x4 & SATA modes)

AMD X570 Chipset
M.2_2 slot (Key M), type2242/2260/2280/22110 (supports PCIe 4.0 x4 & SATA modes)

My CPU is Ryzen 9 5950X.

I performed write tests and I get about 1.6GB/s on the NVME in M.2_1 and 490MB/s on the NVMe in M.2_2.
Is this correct?
Do I need to change something in the BIOS?
Please advise
Thank you

M2_2 based on your included description will benchmark slightly slower than M2_1 because it has to go through the chipset rather than being directly connected to the CPU. In real world usage, you won't be able to tell the difference.
