I'm owner of Dell Inspiron 7567 (1Tb SATA disk is used).
I'm pretty interested in Intel Optane 32GB M.2 2280 PCIe 3.0 x2.
But it was found that other Dell Inspiron 7567 user have the problems with Intel Optane - https://communities.intel.com/thread/116010
The official answer of Intel Corporation:
We understand you would like to use Intel® Optane™ Memory Technology but the software does not work to enable it.
We'd like to inform you first that, the Intel® Optane™ Memory Technology, was first targeted to work in desktop computers. For laptops or mobile systems will be available at a later date. For more information, you can check this link.
We do know that, even if your laptop meets the requirements, the reason why it may not fully work is that the BIOS is not Intel® Optane™ ready and will require at least the Intel® RST version 188.8.131.521 installed on it.
Manufacturers should provide this BIOS update, so it can fully work for this purpose.
Please let us know if you require further assistance.
Are there provided any fix to the problem?
Does the latest at the moment Inspiron 7567 BIOS driver (01.00.07) support Intel Optane?
Right now, no - your system has no optane support.
The Dell systems that do support Optane are listed here (and are all desktops)
I've checked and found that Lenovo have a lot of Laptops with Optane support.
Assus is moving in the same direction.
And what about you, Dell?
Please, provide some information about plans on the compatible with Intel Optane for Dell Laptops.
Should we wait for some BIOS update for Dell Inspiron or there is no other way except buying the Lenovo ***-devices?
Lenovo is shipping a few Thinkpads -- high end business models -- with Optane support. Expect Dell to phase it in starting with competitive Latitudes (and probably Alienware and possibly XPS models).
Don't expect it in Inspirons - low to mid-range consumer systems - any more than in Lenovo IdeaPads.
It may eventually get there - but it'll start at the high end and trickle down - as technology inevitably does.
