I am trying to run the board in 16x8x8x8 configuration(Without M.2), its now running @ 16x8x8x4.
I tried looking into the bios to see if I can change the port speed, nope.
I also looked at Gpu Post under bios, only 3 Vga's are detected, the last one is null but it is connected.
This is mainly a folding@home/Boinc rig(Xeon Cpu).
I was also trying to use an M.2 and run the Board @ x8x8x8x8, nope.
I also notice that some people had to mod their bios in order to get correct Speeds of all of their slots.
Cpu I am using: Xeon, 12 core/24 Threads(40 PCIE-E Lane Cpu).
In the users manual, it says you can run it @ x16x8x8x8, "IF" your not using M.2 in which I am not and a 40 Lane Cpu(Which I am using).
I am using the most, up to date bios firmware of this motherboard.
Any help would be Appreciated, thanks.
EDIT:
I looked up this info:
https://www.win-raid.com/t3323f16-Guide-How-to-Bifurcate-a-PCI-E-slot.html#msg45202I used a program called: AMIBCP and looked for the: IIO PCIe port, I only see 3 ports, 4th one is not there, why is the 4th one is missing?
Under IIO, there is 4 within the drop list, II0,II1,II2, And II3, If you look into any of them, Look for: (IIO PCIe Ports), there is only port 1,2 and 3 within each IIO.
I am still very new into Bios Modding, Hopefully it is not needed for what I need.
Just heads up:
I checked on the top right of the mobo, The Pci-e Lane switch, during boot up, the 4th slot is flashing a bit, after everything is settled down, once in the bios, only Slot 1,2 & 3 is lit, 4th one is not lit and under gpu post, under 4 slot, it says: No Vga Connected and its running @ X4 speeds.
And yes, I tried switching pci-e #4 with the lane switch, doesn't seem to do anything.
Has anyone ran into this problem before with a 40 lane cpu?
EDIT:
Apparently I have fixed the situation, it was quite crazy.
