So I reinstalled Windows again to remove everything and only installed drives and bench marking software. I was still having the same issues. After troubleshooting more and more I found that if I moved my GPU to a different PCIE slot, everything started working as expected. Although this brings up new confusion and questions for me.
Here is the layout of the board:
Here is what the manual says about GPUs:
Here is what is says about the M.2 slot
So here is the conclusion and issue and workaround.
- I have a single GPU. So for best performance I should put it in PCIE2.
- I have an M.2 drive. I should put this in the M2_1 slot as this allows for the fastest bandwidth and support Gen3.
This setup is what is causing the issue. When I move the GPU from the PCIE2 slot to the PCIE3 slot...everything starts working as expected.
My guess is that the M.2 drive is hogging up all the PCIE lanes that the PCIE2 slot is trying to use.
Here is what I need help understanding:
- Im confused as the m2_1 slot says it disables the PCIE4 slot if used. So I figured the M.2 drive uses the hardware assigned for that drive. Why does it appear to be effecting the PCIE2 slot?
- At the same time, am I seeing a performace drop on my GPU because it is on an x8 PCIE slot and not a x16 PCIE slot?
- If I wanted to due an SLI setup, it says I would need to plug my GPU into PCIE2 and PCIE3, but if PCIE2 is acting up because of my M.2 driver...could this even be a feasible setup?
- If I put a second M.2 drive in the M2_2 drive which says it would disable PCIE5, is my PCIE3 slot going to start acting like my PCIE2 slot is now?
I dont know if I just dont understand how the new NGFF drives really work or if my motherboard is malfunctioning.
Thanks for any light anyone can shed on these questions or my misunderstanding on the setup.
