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.
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 installing new chipset drivers.. the latest 1080ti drivers were already installed (385.41).
I changed 64 bit encoding to enable, and the PCI-E Gen from auto to GEN 2 are only in 2 places (PEG0 and PEG1), don't see any others.
The only other option is PCI Latency Timer, which is set at 32
