straight forward question:

i currently have a motherboard found that has a pcie 3.0 x4 slot and support intel optane. but intel optane has a pcie 3.0 x2, will it cause problems or will i be fine?

optane module act as fast cache for any SATA base drive, the abstract picture is that it will gather frequently used file from lower interface SATA interconnection to higher PCIe interconnection, in term of latency, having data on low latency optane module, the CPU can cut down input/output operation read/write process cycle compare if CPU'd access it on higher latency HDD. You'll have to update BIOS so motherboard will operate as it should.

okay, so be more precise:

The Motherboard: MSI H370M Bazooka + m.2 (S600/Pcie 3.0x4) slot
The M.2 card: Intel Optane 16 GB + M.2 pcie 3.0x2 slot

will it work without problems?

Isn't the Optane M.2 designed to slot in to an M.2 connector? If so, it won't slot directly in to a PCIe slot since, while M.2 uses the PCIe electrical interface standard, the mechanical interface is entirely different.

Do you mean with an interface adapter card? If Optane can use an IAC I'd imagine it would adhere to PCIe standards in that the 'slot' would automatically adapt itself to the bus width of the card plugged in, up to the maximum bus width the slot is wired for.

PCIe is very flexible that way: you can even plug an x16 card into an x1 slot and it would work at x1 bus width. Just cut out the back of the connector.

i understand that, but there is a clear m.2 slot on the motherboard itself. i am not talking about a pcie slot as an expansion card. so the intel optane card will fit in the in-build m.2 slot with a little bit performance loss?

and if so, you recommend a x1 optane card with a m.2 adapter?
