Yep, using it now and works a charm !!!
But took me a solid 48 hours of investigating to get it working
Where are you at ?
Steps i took to get it up and running as follows;
1. Make sure that the Optane module is in the correct M.2 slot and that the hard drive you want to link is in the correct SATA slot per your motherboard manual. (For my ASUS Z370-H Gaming board this was M.2_1 which linked with SATA_1 or SATA_2)
2. Convert your boot drive (yes, even though your not accelerating your boot drive) to GPT partition from MBR (Master Boot Record). You can double check that you are currently in MBR by going to "Disk Management", right clicking on the boot drive, selecting properties and then going to volumes and if the Partition style is listed as MBR you will need to change it, the good news is that it isnt that hard;
3. Via cmd administrator prompt you need to run a System32 program called MBR2GPT.exe, you can find instructions on this in the following video:

If you have an issue where is does not allow you you can retype the command and follow it with the /allow command as instructed
4. Restart your PC into BIOS (or UEFI now) and change your CMS to ensure UEFI first is selected for your Storage devices
5. Save and restart into windows and install "Intel Optane Memory" program to enable the Optane module and link it with your secondary drive
6. If you get prompted for a Firmware update you will need to "disable" acceleration of the Optane module first in the Intel Optane Memory program, restart your PC first
7. The download Intel SSD Toolbox and click on Firmware to guide you through the update. Restart, enable the acceleration in the Intel Optane Memory program again and do a restart then your all set. Finally
