XPS 8920 M2 SSD in Optane slot

I have a 8920 SE with the M2 Slot NVMe pc300 SSD and as I tried it will not take the SK Hynix Drivers from their website. Dell blocks the drivers, So Dell limits the drive speed of reads and writes. When I had the Black face 8920 Optane and My samsung 850 pro I was getting reads of 3800 - 4000 with the SK Hynix drive I get 1700 - 1800 with no Optane Memory due to the slot is being used

Now my question:

Is the #8 in the service manual SSD Drive Slot also the Optane Memory slot?

Can I get a M.2 Adapter X4 PCIe 3.0 NVMe Low Profile And Full Profile SSD PCIE M.2 Adapter


and the put the optane memory in the $8  M2 slot

Would it do the same speed as the m2 slot in the PCIe bay and will the optane memory use it as the first hard drive.

Would this work like I want its too?

Anyone else do it?

Is there a better solution without buying a new Hard drive?

Or should I just sell the M2 SSD Drive and get the optane memory and use my samsung 850 Pro SSD?

Please help I'm still pulling out hair LOL

RE: XPS 8920 M2 SSD in Optane slot

Thank you for the instruction for DELLs Driver. This has nothing to do with what my questions was, you provided a copy and paste of the Dell firmware update for the drive. Please review my full question about optane memory and putting the SSD in a PCIe cradle.

RE: XPS 8920 M2 SSD in Optane slot

Optane slots are limited to 32G - and are designed as a cache for ONLY SATA drives (hard drive or SSD).  So -- assuming what you're asking is "can I put an M.2 drive in the optane slot and then access it as a boot or storage drive by itself?", the answer is no -- you cannot.

Optane will cache ONLY SATA drives - not M.2 drives at all.

As for installing the drive in a PCIe adapter, that should work - but whether you can boot from a drive installed that way is open to question.  Given the engineering quality of a $20-30 PCIe adapter, I'd guess it to be hit or miss at best.
