SOLVED! - read below to see solution.

I have the SB-Rocket 1TB installed on a X570 Aorus Ultra Motherboard.
I'm only reaching 3307 MB/s in sequential reads; 33236 MB/s sequential writes.

Please advise as I await Sabrent support.

Do you get the same results if you try it in the other M2 slots on the board?

Yes, this. That CDI sshot seemss to indicate that you are running in 4.0 x2 mode for some reason.

The MOBO manual had this as footnote:
*The M2C_socket connector supports up to PCIe x2 SSDs only.

I was using the M2C connector as the stand off was already accommodating the drive that size. I removed the standoff and moved to fit the smaller size Sabrent Rocket in M2A_Socket connector and voila it worked!

Nice looking much better.

Here are the numbers I get on my Corsair Mp600 drive.
