NVME on a Z170 pro board

[bits2000]

Will a Samsung m.2 950 pro nvme drive take from PCIe slots or sata slots on an ASRock z170 pro board. I want to put 2 of them on and I am also running 2 R9 270 video cards in crossfire. Will the PCIe slots not work or will the sata ports not work?

In most likely hood, the M2 slot will use the 4x PCIe lanes from the 20x lanes of the z170 chipset.
If you're that concerned, you can go ASRock site and download the manual for the board which should clarify the information.

I did look at the manual but it says the sata ports will not work but I am thinking it's a m.2 that works off of sata not nvme m.2, since the nvme works off of the pcie lanes.


I guess they just run down to 8x or something. I don't know.

Thank You.

The Z170 chipset itself has 26 HSIO lanes, 20 of which are PCIe3.0 lanes of which MB manufacturer can, with some restriction, configure as whatever they want.

A PCi-E storage device can be connected to HSIO lanes 15-18, 19-22, or 23-26; however, they cannot be connected to any other group of 4 HSIO lanes.

In each of those configurations, the PCIe x4 lanes will always overlap with 2x SATA ports and therefore 2x SATA ports will likely be disabled whenever a PCIe device is used (the first 2x SATA can be configured at 2 specific lanes each-either as lanes 15-16 or 19-20 to avoid conflict with the PCIe based storage device, depend on the way the MB manufacturer configure those lanes however, the secondary lanes configuration for the SATA ports may not be available and they can get rendered unusable immediately when the PCIe device is installed).
