Motherboards for most GPU that will work. Advice please!

Since this is a mobo thread i thought i would ask some help.

In a nutshell

I bought GIGABYTE G1 Gaming GA-Z97X-Gaming 7 LGA 1150 to build a zcash rig.
This one from new egg
http://www.newegg.com/Product/Product.aspx?Item=N82E16813128708

together with 4 RX 470

and pci risers.

The problem is that the cards will not power up unless i connect the riser directly on the cpu, and even then it cannot see more than 2 cards. It just shuts down and the screen flickers.

I though this would be an awesome mobo to host 4 cards, but it seems i was wrong.

Anyone encountered similar issue? Do you know of any workaround?

Gigabyte support has not been of much help. They suggested to update BIOS which i did but the problem remains.

Any ideas more than welcome

many thanx

Hi.
What risers do you use?

PCIE slots on this board can work here in these conditions:
1x16
2x8
1x8 and 2x4
Theoretically, the maximum you can set 3 GPU. In practice differently.

What you can try:
1. Check that all your GPU work separately through the riser. Check each riser. Check each card in mining separately.

2. Next, take one card with  riser and check how it will work in each of the PCIE slots. In some slots, it might not work. GPU put in is not necessary to further in these slots. Remember in what slots worked GPU.

3. Add one card and see what happens. It is best to completely remove the native driver. How much GPU will work, see the device manager.

I tried different positions of risers and it worked
