I'm betting that slot is unpopulated.
M2_2 is the second slot. for M2_1 the primary there is no choice for X2, You get auto, PCIE or SATA, set it to PCIe.
For M2_2 if its unpopulated it will default back to X2 every time.
download and run crystal benchmarks on that drive with default configuration. At x4 you should be getting around 3000 MBps sequential reads and about 1400-1600 in sequential writes.

Hi Daniel,
You in fact cannot select the speed in M2_1. Its fixed at X4 as the primary M2 port. It only allows for you to switch between Auto, PCIe and SATA in the event you wish to run an M2 sata drive. M2_2 does allow selection of what speed and defaults to X2 is unpopulated or if the SATA ports (Generally Sata 5 and 6) that is shares bandwidth with is populated.
You speeds are right on target for a 960evo and at x4. :cool:

Hi guys, I also have a MB Asus Rampage IV Extreme and can not read it as the primary 256GB SSD boot.
how can I do? I have a built-in PCI-and Hyper Express Asus adapter
If you are using the hyper express it has to be in PCIe_4 to work as well as having the latest bios as Chino stated.
