While enabling system acceleration, you may encounter problems detecting the module within the:

Intel® Optane™ memory capable applications
Windows® 10 utilities (such as Device Manager)

Here are some techniques and methods you can use to resolve detection issues with Intel® Optane™ memory.

Symptom

Possible Cause

Recommendation

Module isn't detected in either the operating system:

Windows* (for example, Device Manager does not detect under 'Disk Drives')
Intel® Optane™ memory-capable applications

But is detected in the system BIOS

The module contains old data and needs to be reset or may not have been disabled properly from an earlier volume.

Refer to your system manufacturer for more details or specific guidance before proceeding to follow the steps below:

Backup all data before proceeding.
Enter the system BIOS.
Locate the Intel® Rapid Storage Technology page.
Click the Intel® Optane™ memory module
Select 'Reset to non-Optane' or 'Deconcatenate' (if the volume wasn't disabled properly)¹.
Alternatively, or if the above steps don't resolve the issue, follow the steps below to remove all partitions:
1. Open Command Prompt (Admin).
2. Type 'diskpart' and press Enter.
3. Type 'list disk' and press Enter.
4. Make reference of the Intel® Optane™ memory module disk number.
5. Type 'select disk#' for and press Enter.
6. Type 'clean all'. When complete the cursor will come back; be patient.

To re-enable acceleration, be sure to confirm all BIOS settings² and procedure as defined by your system manufacturer. The Installation Guide can also be referenced.

Windows* Device Manager and Disk Management detect the module, but the Intel Optane memory or Intel RST application don't.

System BIOS is not configured properly for acceleration and the Intel® RST controller to detect. The windows apps may be detecting the devices, as the Microsoft NVMe* driver has been loaded.

Refer to your system manufacturer for more details or specific guidance before proceeding to follow the steps below.

Backup all data before proceeding.

Confirm Remapping is Enabled for the PCIe-M.2 port that contains the module.

If the settings were correct and the issue isn't resolved, check the following settings in the system BIOS:
