I have just updated my 5 year old system with a new motherboard, cpu and ram.
I used before a Gigabyte Z97X MB with a Intel 4790K cpu and 16 GB ddr3.
The 750 SSD performed at 100% perfect the whole time.
Now installed in a MSI X470 mb with a AMD Ryzen 7 2700X and 16Gb ram.
Install in the only correct pci-e slot, number 3 supporting 3Gen at x4.
However the great performance of the 750 is completely failed now
Eg. intertal transfer used to be average 400Mb/s and is now 35Mb/s.
It is very clear when running a ATTO test.
after 8MB the drive is "broken"
MSI support will only accept CrystalDisk, but in my opinion is gives a false image of the true speed.
Has anyone seen this before?
