Thank you for posting in the Intel® communities.
Could you please confirm if you are trying to accelerate a RAID 1 array or just a secondary drive? I’m a little bit confused about this.
On the other hand, could you please download the Intel® System Support Utility (SSU) from the following site and run the full report to collect your system information? The tool can be downloaded from this site: https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-. Please attach the report file in your response.
Please also take a screenshot of the following information:
- Open your Command Prompt as Administrator.
- Run the command Diskpart.
- Run the command list disk. Please take a screenshot of the output and include it in your response too.
I’ll be waiting for your response.
Have a nice day.
I was trying to accelerate a stand alone SATA SSD that is being used as a secondary storage drive and run windows, unaccelerated off a 2nd m.2 NVMe drive.
I eventually found a solution which identified the actual problem I was having. My motherboard has two M.2 slots (M.2_1 and M.2_2) both slots support Optane acceleration, but because I was trying to use 1 M.2 as a GPT boot drive rather than a separate SATA device it was being rendered inoperable during the Optane setup processes.
What appears to have been happening was that when I was enabling RST Premium and (unintentionally) M.2 Raid support for both M.2 devices the GPT functionally was lost. By enabling CSM it was ignoring the M.2 RAID support and allowing it to boot. The solution was ensuring the M.2 Raid support was enabled on the M.2 slot with the Optane card and not on the NVMe with windows installed on it, or the target of an installation. It was further obfuscated by the Optane Memory Setup program, which, after running initially it "Changes Bios Settings" to make the chip active, and rather than just enabling RST and the M.2 RAID for the Optane card, it arbitrarily enabled RAID it on both slots which returned me to a non-bootable scenario where the GPT was not addressable. The software is obviously not programmed with multiple M.2 slots in mind especially when one is intended as a primary boot partition.
I published a PSA about it on tom's hardware :
