I have an ASUS Prime B250M-A motherboard with a 7700k CPU. Installed 16 GB Optane in M.2_2 (the one further away from the CPU), but it is not recognized in BIOS, device manager or diskpart.
I have 3 SATA HDDs connected to ports 1 (boot drive), 2 and 3.
1.System Support Utility report.
2.Disk management screenshot.
3. Device manager screenshot.
4. Diskpart disk list screenshot.
When I ran the Optane utility, it said that my system is Optane ready, but no Optane modules were detected.
Your help is much appreciated.
While your system does seem to be booting in UEFI mode, it seems that your BIOS may be on a hybrid mode, not full UEFI.
Please make sure the following is disabled:
BIOS UEFI > Advanced Mode (F7) > Boot > CSM (Compatibility Support Module) > [Disabled]
As far as I could tell, both M.2 slots should be Optane™ Ready, so placement shouldn't be an issue.
However, you may also want to make sure the M.2 slot is set to PCIe mode:
BIOS UEFI > Advanced Mode (F7) > Advanced > Onboard devices Configuration > M.2_2 > [PCIe] [x2]
Let us know if this makes a difference.
In your BIOS, under Advanced, the very last menu down the list should be for Intel® Rapid Storage Technology.
Please check to make sure that your Intel® Optane™ Memory is being displayed here along side with your other storage devices, if not, test installing it on the other M.2 slot and check again. Once it's shown, you should be able to proceed with the installation.
If it's not detected still, you may need to engage your motherboard manufacturer to find out and troubleshoot this from their end as well.
One thing I'm concerned with, despite your settings, the SSU report that you shared with us show Windows* as being run in Legacy BIOS mode. This doesn't make much sense as I can see that your system drive contains an EFI system partition (this means it is GPT, which only works in UEFI mode).
1. If you open a Run window (windows* key + R) and open MSInfo32.exe, under System Summary, does the BIOS Mode also show as legacy?
2. When you took those screenshots, was the Optane™ Memory physically installed? (it should show as an uninitialized drive, as a small NVMe* SSD).
1. MSInfo32 shows BIOS in UEFI mode.
2. The Optane is physically installed in the system but is not shown anywhere, in windows or in BIOS.
3. I moved the Optane to M.2_1, nothing changed.
4. I reinstalled windows, nothing changed.
5. I'm waiting for a reply from Asus regarding this.
Based on this, your motherboard, BIOS version, and settings are all compatible and ready for Optane™ Memory. This leaves us with the following possibilities:
1. Your Optane™ Memory module is defective or DOA (dead on arrival). If within the original 30 days, you should be able to replace it through your place of purchase, if not, you may do so through our https://www.intel.com/content/www/us/en/support.html support team.
2. There's something wrong with your BIOS. Since you're also working with ASUS* they should be able to confirm if this is the case.
Your motherboard and BIOS version are both compatible with Optane™ Memory, and your settings all seem to be in place.
I have an ASUS B250 Prime motherboard with Optane enabled and I have a suggestion you might want to try. I'm not sure, but I think I remember having to disable Fast Boot in the uefi bios to get the board to recognize the Optane module. I'm not positive but it is a very minor change to make and you can re-enable it easily after trying again to enable Optane.
I was hoping this was just us missing some BIOS setting. Regardless, let us know if the second computer is able to detect the module or not.
Before being enabled for system acceleration, your Optane™ Memory module should show up as an uninitialized SSD on Disk Management.
If you're able to detect it, and decide to enable it, make sure to disable system acceleration from the Optane™ Memory Software before removing the unit from that system to avoid issues.
