Default problem MP500 (240GB) slow speed


I recently bought a few MP500 (240GB) m.2 PCIe x4 NVMe SSDs for several of our machines at work.

I experience slow performances on 2 machines running Windows10 x64 and based on Asus Prime Z370-A mainboards. I get a couple hundred MBps at best for both write and read (at least 10x less than advertised). The M.2 sockets on the Z370-A are PCIe x4... Should be OK, right?

I get much better results when the SSD is mounted on a PCIe x4 to M.2 adapter card on an Asus Z97-A board (write 1000MBps, read 2200MBps). I use the adapter card since the onboard M.2 socket in the Z97-A is only PCIe x2. This machine is running a patched version of macOS Sierra, not Windows10 so I don't know about the drivers or anything...

I didn't try to use the adapter card on the Z370-a boards, yet...

I suspect I forgot to install some drivers into windows10. However I found nothing relevant on the web pages corresponding to the MP500 or the Z370-A... In addition, Windows doesn't flag any devices as not properly detected.

Maybe a poor BIOS setting? I checked but found nothing (I am not super familiar with every BIOS settings, though...).

Any advice is welcome.

Thank you very much in advance for your help.

You'll want to put in a support ticket with Corsair and see whether they can help.

Check your manual and see whether there are any restrictions when using the port, e.g. SATA ports are disabled, PCIe card slots,etc.
