Optane Memory not operating, desktop painfully slow.

[ridgerunner47]

I recently had problems getting my HP 590-p0081c with 16gb Optane Memory (Mod #MEMPEK1J016GAH) to boot past a BLACK SCREEN. After reinstalling Windows 10 and experiencing some corrupt and missing files, I replaced my hard drive with the same model (Seagate ST2000DM008) cloned drive without first disabling the Optane Memory in the BIOS.
After installing the cloned drive, my PC runs painfully slow and I started getting a YELLOW FLAG in the bottom right system tray stating that " PCIe SSD is offline" (clear metadata?) After clearing the metadata, I no longer get the YELLOW FLAG but computer is still painfully slow loading (4 mins 3 secs to PIN screen) and shutting down (I don't think the Optane Memory is being utilized). My question now is how do I re-activate the Optane Memory module?
Intel keeps referring me back to my vendor but I have not been able to get any help or information from HP about RE-PARING the Optane Module with the cloned hard drive.
Intel suggests going into BIOS, Advance and activating Optane Memory then going into the Rapid Storage Technology software and "Enabling Optane". However, when I go into my BIOS (American Megatrends 2021 version 2.20.1271) under Advanced there is no option to disable or enable Optane Memory. When I try using the "Rapid Storage Technology" software to Enable the Optane Memory I keep getting the following:
"(0xA0050055): An unknown error occured while an operation was in progress. The operation could not be completed."

I have since disabled but NOT uninstalled Optane Memory through Device Manager
1. Is there a way to restart the Optane memory so that my PC operates properly again?

2. I have an Intel MEMPEK1J016GAH Optane Memory module in my HP 590 p0081c desktop. Is this an H memory module or M memory module?

Intel RST works best with 10 and 11 generation CPUs.   Your system as 8th generation from reading the spec.

When your system was built it should have had the correct intel drivers for rapid start technology and configured for use with Optane.  I do not know if HP has a system restore for your configuration.  If they do, then be sure to bring up the BIOS first and make sure that RST is selected and  not  AHCI before re-installing.

Some info but really only for 10 and 11 gen intel is here 

IMHO, Intel's RST was good for windows 7 but the latest SSD and M.2 make it old technology.  Intel has come up with much larger Optane like 256gb and higher and in the $500 and up range.

My Area-51 had option for Optane but I switched to AHCI and made the M.2 a cache to speed up all my hard drives.

Consider one of the following (select AHCI boot instead of RST and uninstall all RST and Intel management drivers)

1.  Install a 1tb M.2 and boot from it as the new "C" drive.  This assumes you M.2 is 2280 or the price will go way up.

2.  Boot from your existing hard drive then

     Install a cheap but fast 256gb M.2 (or even smaller) and configure Primo Cache to use it to speed up all your hard drives.

Microsoft is working with game developers for "direct store" game speedup.  This is being discussed at the PrimoCache forum and Microsoft has not released technical info to anyone else.  I believe this affects windows 11 only.
