Were you ever able to get Windows to recognize any GPU in an x1 slot?
For example, if you remove all cards and attempt to install a second one using a riser into an x1 slot, what happens? (If it still fails, try again with a different card and then a different riser.)

i run 4 Card in the blue slot,
did try with 1 Card without 1 riser and 1 riser in the white slot it runs ...
thats kind of wired

there was the GPU in the device manger, but it was unable to get install driver or to choose a dir for drivers.
today i get and other PSU and then i get try more, cuz now is runing 4

Hi all,


I have the same motherboard but I couldn`t get the 4th GPU up for any reason.The GPU isnt seen on device manager nor on gpuz

When I replace the riser`s place 4x to 16x only 16x works. (4x is yellow small one.2nd from the right on the picture on this thread..assuming i am right on the speeds...

8x         16x       16x             4x                1x
empty   1070     1070      notworking        1060

I have started to think as this MB doesnt support more than 3 but read here some people was able to do it work for 5 GPU.

I only need to add one more GPU...

my psu is corsair hx1000i so enough power for the whole system.

Any comments why it didnt work with 4 GPU.


edit:has just tried to move the gpu to the 8x slot which didnt help..still 3 gpus are seen.

The moved riser was working ..riser works on other slots..


actually again started to think does it only support 3 gpu?


edit:1060 the working 1060 is seen on system manager but not involved on any mining software.
I dont undestand what is going on here.

as final only 2 16x working with 1070s
