Samsung 970 Evo is not reaching full speed?

[Pavilion]

I don't know why but this is my second Nvme Samsung drive. For some reason, the drive is only reaching 1600 MB Read & Write max, my other drive on a different computer is reaching 3400 MB Read and 2900 MB Write? any idea what's affecting the speeds?

Did you see what happens when you switch the slots yet?

I used the smaller slot not the bigger one because the heatsink will fit better with the smallest slot. If I changed the slot will this affect the speeds? or they are basically the same?

Just see if it runs at full speed in a different slot, one of the slots might run through a chipset or something and be a bottleneck.

Ryzen CPUs have 20 PCI-e slots, + 4 from the chipset I think

Ok, I will try to change it today, I hope It will be easy because liquid pipes are on the way. I will get back to you.

Just do one at a time probably and see if they run full speed in the known good one's slot first.
