Then don't buy the equipment. End of story.

Last update, I was able to get 8 GPUs running using both m.2 ports with adapters. I'm not even using PCIE_X1_2 anymore. It will just be a free slot on the board, I could never get it to recognize a card. You must disable the 3.1 front usb in the bios and select the PCIE ports. Also set the m.2 to use PCIE.

Good luck!

Some say I'm still driving.

Are you only looking at online stores? I drove 3 hours one way to get 8 1070tis from a microcenter, in the snow. Good prices are out there. You just can't sit there refreshing amazon & newegg hoping to see low prices.

Software related issue? Drivers, maybe?

I've been able to get 6 GPUs now recognized. Here is a run down of what I've done.

*Going from memory, because I don't want to shut the machine down and actually look*

* Disabled front 3.1 USBs, and selected PCIE_X1&PCIE_X4 -- It is a drop down selection.

* Went to USBs and disabled all but the two we are using for mouse and keyboard (USB13/14) !! After I did this, I got the 6th card recognized

* Switched TWO PCIE settings to GEN2, forgot exact location, but it is under PCH Configuration, left speed to auto.

* Disabled all SATA not in use, except our hd (We had a 32GB Thumbstick, but it was painfully slow installing drivers on because of heat throttling, switched to a hard drive)

* Disabled, bluetooth, wifi.

Thinking that was all I have done so far. Researching about disabling the on board graphics and running my monitor off the card in the pcie_x16/x8_1 slot. Will update once I find out more.

Hello all, I recently purchased 8x 1070tis and the ASUS Z370-E Gaming motherboard. I looked through the manual and might have wrongly came to the conclusion that I could run at least 8 GPUs on the board.

Currently I can get 5 GPUs recognized, I found in the manual that if I disable the front 3.1 USB that I could get PCIE_X1_2 and PCIE_X1_4 to work. That doesn't seem to be the case though as I have disabled the 3.1 front USBs in bios (and actually selected PCIE_X1_2&PCIE_X1_4).

I have swapped working cards into those slots to no avail. Any insight would be greatly appreciated considering there isn't much information out about this board yet.

Here is a english link to the manual.
