Question Slow SSD performance on M2_3 port, can anything be done about it?

[Sumitomo]

Hi,

so I have 2 identical Samsung 980 Pro SSD 1TB in my system.
One in the M2_1 port and one in the M2_3 port.
The motherboard is a Meg Unify x570.

The SSD in the M2_3 port is much slower than the one in the M2_1 port.

M2_1:

vs. M2_3:

When I check with HWiNFO, I can see the current link width is 1x for the slow one, as opposed to 4x for the fast one.

is there anything I can do to get PCIe 4x4 speed?

check bios settings?

Swap slots see if the problem follows the disk or the slot.

Thank you guys, moving the slow disk to M2_2 did the trick, they're both quick now
