Two m.2 SSD and one sata drive

[TheIceMan]

I've been running a 512gb 960 pro in m.2_1 and one wd blue mechanical drive for about 2 years and have been pretty happy. During boxing week I purchased an xpg sx8200 pro 1tb and installed in m.2_2. there's an option in the hero ix bios to run the m.2_1 in PCIe mode and there's an option to run the m.2_2 in x4 mode. I am also running a 1080ti in x16 mode obviously. But the 960 pro in m.2_1 is running slower than it used to and quite a bit slower than the xpg. What am I missing here?

Did you figure it out?
After just rebuilding one of these there was a note in the manual about modes and also that using the 2nd m.2 slot would "shut down"(?) specific sata ports.

I've just installed an EVO970 and a PM981 with both working at good speeds.

Sorry OP, I was mistaken. :confused:
Page 13 of the manual in section 1-30 it stated something about the slots, but turned out it was sata not NVmE related:

When the M.2_1(Socket 3) is operating in SATA mode, SATA port 1 (SATA6G_1) will be disabled.

Second reference I just found is at the bottom of page 84 @ section 3-18 (Onboard Devices Configuration):

M.2_1 Configuration: [Auto][SATA mode][PCIE mode]
[Auto] Auto-detects the M.2 device mode. If a SATA device is detected, SATA6G_1 will be disabled.
[SATA mode] Only supports M.2 SATA devices. Please note that SATA6G_1 port cannot be used in this mode.
[PCIE mode] Only supports M.2 PCIE devices.

M.2_2 PCIe Bandwidth Configuration: [X2][X4]
[X2] Run at X2 mode with SATA6G_56 enabled.
[X4] Run at X4 mode for higher performance with SATA6G_56 disabled.
