I recently installed an additional M.2 drive into the second slot of a STRIX Z270G
Once I powered on, I was helpfully informed that:
An M.2 PCIE device has been detected in the M.2_2 socket.
PCIe bandwidth on the M.2_2 socket can bet set to X2 or X4,
default X2 configuration shares bandwidth with the SATA_56 ports.
To improve performance,
go to BIOS/Advanced/Onboard Device Configuration and switch from X2 to X4
Now that's all well and good.. But no such BIOS options are available no matter how hard I look.
Subsequently, I've not seen this warning appear again - and the device seems to be functioning correctly at X4
It's worth noting that I'm not using any SATA devices at all, and out of an abundance of caution have disabled SATA entirely - but it irks me a little that such a warning would present - yet not be actionable at all.
Bios is up to date.
Version: 1301
Release Date: 03/014/2018
Did I miss anything?
