A320M-HDVr3.0 - nvme only running at half-speed

Sequential Read (Q= 32,T= 1) : should be @ 3400, is only 1700.

I put a Corsair Force MP510 240GB on this entry-level new-build machines board but cannot get the read speed over half what it should be?? (used 3 benchmark apps).

CPU is Bristol-Ridge A8-9600
RAM is HyperX DDR4-2400 (2 x 4GB)

Due to shortage of Intel gear, this is first time I've bought an AM4. I've never had a prob with these on AsRock Intel boards.

I've triple-checked BIOS settings - but I MUST be missing something??

Can anyone help with this please?
