@tytanik - i experience the same issue issue like most of users with NV and more cards.
H110+ 13 x P106 setup, found everything from the start, have the following problems:
1. Overclocking works pretty strange, to clock the memory of the P106 from 4000 to 4900 i needed to put 1600 as parameter. Steps that increase the MHz are really not relevant. Putting 900 clock to 4400 something.
2. Finally stabilized the machine to 325MH and runs well but it reboots without reason 14 times for 10 hours. Temperatures are under 65C, target is 76C.
So how to fix those nonsense reboots ?

Yes, please do let us know how to fix these constant reboots on H110+ 13 x 1070 setups. Thank you.
@tytanik I experience the same issue and my 2 cents are, that the issue is a side-effect from server side changes for v1125 where you fixed some OC stuff for RX cards, but now configuration files for NV cards are not properly generated anymore from settings that perfectly worked before.
Following message appears when trying to apply the OC settings:
Invalid MIT-MAGIC-COOKIE-1 key Failed to connect to Mir: Failed to connect to server socket: No such file or directory
Unable to init server: Could not connect: connection refused
ERROR: The control display is undefined: please run `nvidia-settings --help`for usage information.
It would be nice to see a fix for this issue! Thx a lot!
