Not getting the full speed from Samsung Evo 970

[backsofangels]

Hello everyone, I built my very first hackintosh and it works quite smoothly at the moment. But I have noticed something that my SSD is not working as the others, when I measured my writing/reading speeds, I am getting very stable 1.500~ each writing and reading speed but I believe my reading should reach around 3.000 right? Does anyone has any idea that might be the cause of this? I mean I am fine with this but if it is easy to solve, why not?

Build: Gigabyte Z370 gaming 7
Intel core i7 8700K

Is this the 970 Plus variant?

Hello, it is Samsung 970 EVO only.

I have two identical Samsung NVMes installed in my Hackintosh and one tests out approx twice as fast as the other. My guess is that it's to do with the sockets on the motherboard: according to the manual socket 1 supports up to 32Gb/s and socket 2 supports up to 16Gb/s. Could your motherboard be similar?

I can give it a try but there is one special heat synced socket, right next to cpu only for NVMe. That would be very awkward if that special made socket provides limited speed.

I think you need to stick it in next slot: M2A_32G. That's where mine is located.
