NVME Issues

I just bought Crucial T700 2TB and I am using the heatsink that came with the motherboard and it's in the correct Gen5 slot.

It's supposedly a 12.4/11.8 GB/s drive but using Crystaldiskmark and even just copying large files to it I am only getting 10.8GB/s read and 2.1GB/s write.

I've been watching the temps in CrystalDiskInfo and they go to around 60-65c during the test, I do get variation on reads depending on the temps by a few hundred MB/s but write is consistently around 2GB/s.

What am I doing wrong?

Yes I made sure to double check, the thermal pad is sticking to the drive.

A large sequential file from a drive that can do 7GB/s reads. Yes I have the NVME option enabled for the test.

Interesting, I cloned my OS back to my old 7GB/s drive, formatted and tested it blank and it gets full 12GB/s read and 12GB/s write now.

The old drive is still getting expected speeds.

Could it have been the drive cloning that messed it up somehow?
