The CPU it self has 16 PCI-E lanes wired to the graphics that why if you use the 2x16 slots they will run at 2x8 PCI-E.

The Z370 chipset have 24 PCI-E lanes, I have the same board and I use a i7-8086K it does have 16 PCI-E Lanes to directly for Grapchis and I use a Samsung 960 EVO 250GB M.2. and my GTX 1080 Ti on this board with bios P3.10 runs x16 3.0 without any issues and under no load it runs x16 1.1.

Just dug out this old thread if someone else comes along with the same issue. Wardog was right.

Still only 8x. Right now i have no second system around for further crosstesting

The M2 doesn't "use' lanes from the GPU, that I can tell.

Your CPU provides 16 lanes. What with 4 being used up via the M2 installed, that leave 12 free. Unfortunately there is no Spec for PCIe x12, so 8 it is .

Just pulled it? Or did you remember to reset the BIOS after also?

I'm not pushing you, k? Just trying to help.

well i just tried pulling the m.2 it stays at 8x

I think i will just live with it as it is not a big deal and everything is running smooth and stable

Was just curious because it was nowhere mentioned in the manual that this m.2 is using up lanes from the GPU

If you want to tinker, pull the M2 drive and in its place do a cheap install of Windows. My guess is by freeing up those 4 M2 lanes your RX480 will be running x16.

well then i will just live with that because its just a loss of 1% power overall.
It maybe some sort of compatibility issue becaue when i first installed windows i almost had to force feed the driver into windows over some shady tricks because the PC always crashed during a normal driver install..

M.2_3 is only shared with SATA3_3
https://www.asrock.com/MB/Intel/Z370%20Taichi/index.asp#Specification
If M2_3 is occupied by a SATA-type M.2 device, SATA3_3 will be disabled.


This doesn't bode well for you!
