now I can't even get 4 cards working... they crash as soon as I start mining

does wiring matter for the separate PSUs? I have three risers and the attached GPUs being powered by one PSU, and the rest of the computer and 2 GPUs and their riser powered by it.

What Miner are you using? start with at least 2 GPU without risers, 1 GPU to the main PCI-e x16, and the 2nd GPU to the next PCI-e x16, then fire up miner.

Use some easy to use miner like EWBF or Claymore for testing or troubleshooting purposes, check also your PSU power rating 1080ti's are power hungry especially when mining. goodluck and happy mining Cheesy

ok, here are the steps you have to do in order to made it work

0. plug only one 1080ti and plug your monitor into MB dvi/hdmi port from CPU
1. update your bios to the latest version possible
2. enter to bios, load defaults, save and restart
3. load windows, install all drivers for intel chispet, then latest driver for 1080ti
4. restart. go to bios, change 64 bit encoding to enable, everywhere change PCI-E GEN from auto to GEN2 ( should be in 3 places)
5. save and shutdown before loading windows
6. install all you cards. load windows, install VGA drivers
7. enjoy

alright, this is a nightmare.. and I'm out of ideas

my initial problem was that i could only get 4 running (one psu) and switched to two psu's and a fifth 1080ti.. When i booted windows it would cause a "Code 12" error.. insufficient resources.

so i did some research and found that I should change "pci e" settings to Gen 1, which I dont have but i do have the PEG0 and PEG1 "Max Link Speed" and I set those to Gen1.. It also said to change "Above 4G Decoding" to enable, so I changed that from disabled to enabled...

...it is working now but...

they are running like absolute garbage, and will crash after a few minutes. The power % looks like its all over the place and they are getting 200sols, 300sols and 400sols, with maybe 1 at 600sol/s

I'm going to throw this rig into the street

my mobo is the MSI Z270 SLI PLUS (MS-7A59)

any help would be appreciated.
