Optane Cache Drive 32gb not detected

Hi,

I'm having trouble setting up Optane, I can't see the Optance memory in the bios or in windows....wondering if I need to send it in for RMA or I've missed something in the setup process.

Once setup I'm trying to accelerate my secondary drive, for the trouble shooting process I disconnected the secondary drive.

Trouble shooting: I've swapped m.2 slots for my nvme boot drive and optane drive, no change, nvme drive is still deleted where the Optane drive was.

Screen shots of the settings I used before reinstalling windows on the nvme drive.

Once in windows I ran diskpart and list disk, optanne still doesn't appear here.
