Hello guys,

I need your help to setup 6x GPU in my rig.

I have:

4x RX470 XFX
1x RX470 MSI
1x RX570 Sapphire

When I put all together the Windows 10 won't start, the login freezes or I get black screen.

I have tried putting only the 4 XFX and they are working after patching.

I will give you a tip if all 6GPU works at the same time

Motherboard: MSI Z170a gaming

I use MSI z170a gaming pro carbon in my 7 GPU rig and recently wrote about it:

A few things to check first
1 Your cpu: is it skylake? kabylake does not work I've heard
2 Mobo bios: must be v 1.7 or above
3 is your windows UEFI enabled? if not it won't work.

A few things to try:
1 uninstall your current driver, use AMD driver cleaning tool

2 restart and in bios setting, disable 4g decoding in PCI settings

3 You should be able to boot into windows now. Download Radeon driver 17.5.2 (which I use and it works, newer ones may also work), install it. You should see in device manager cards recognized by some may have question marks on them.

4 restart and in mobo bios, enable 4g decoding

5 boot into windows and wait for it to recognize and set up all cards.

Should work now. Hope this helps.

Many thanks for your post, I'm following one by one your instructions, yes my windows is in UEFI I checked it in msinfo32

My cpu is a cheap one: Intel Celeron G3900 2.8Ghz

I'm checking now the bios and its settings.
