Hi guys, so i recently purchased an M.2 SSD Samsung Evo Plus 250gb NVME. I mounted it on my mother board GIGABYTE Z97X-UD5H and installed windows on it. After some benchmarks i saw that the speed lock at 835mb/s on Reading and 775 on Writing. On the Samsung Magician program i saw that the SSD is running on PCIE Gen 2 x 2 interface instead of PCIE x4 and i think this is the problem. He should run at 3500mb/s Read and 2300mb/s Write. Can i solve this problem with an PICE x4 adaptor? Any tips? I've been struggling with this for 2 days..
May we assume it is a Samsung
970 EVO Plus?
The PCIe Gen2 x2 is exactly the issue as to why your drive is not seeing that advertised speed. Your old motherboard is limiting it. I have that same level board (parts list below).
Would you see full speed if used in a PCIe adapter in one of the slots? Yes, probably.
However, you may not be able to use that as a boot drive.
Not all Z97 era boards can boot from that. Only if there is a
specific BIOS update that addresses that functionality.
And that may cut down your GPU performance.
In my ASRock Z97, I simply put my Intel 660p in a PCIe slot and adapter, and use it as a secondary drive.
The existing 850 EVO boot drive is just fine.
