Allright.. these are my results from yesterdays extensive testing
First of all:
AsRock H110, 8x PowerColor RX470 4GB (samsung), Claymore 10
Windows 10 Pro 1703, AMD 17.10.2 with Workload = compute
We had the rig running stable for weeks/month with BlockchainDriver(23aug).. 228MH's on ETH with this crappy cards
We did DDU, installed new driver 17.10.2(oct23) (full installation with GUI) / took like 15 minutes ! restart + PixelPatched + restart
Manually setting Workload = Compute for all the cards .. grrrr!!! after setting all 8, you have to restart the computer !
After start: OverdriveNTool 0.2.0 for aplying OC/UV profiles to the cards..
result is very same like the BlockchainDriver(23aug) .. 228MH's .. stable for 24hours
So my insight on this.. for those running 8 card rig with BlockchainDriver(23aug) there is no point of switching to the 17.10.2 .. there is no improvement, just the pain (aplying Compute ON) to even get the same result
-----
COMPLETE DDU 17.0.7.7
Adding 4 more PowerColor RX470 .. sooo .. 12 Cards in total (
http://prntscr.com/h31ld0)
Windows booted up quickly
Installed full version of 17.10.2 took like 40 minutes !!! Insanly long! restart + patch
All cards has been detected, I saw 12 in Device Manager (
http://prntscr.com/h31kuu)
manualy turned on compute workload (took another 10minutes) + restart
Computer freezes.. restart, freezes, freezes..
After a long while it booted without any changes at all
Saw all 12 cards, modifified Overdrive batch file to OC/UV all my 12 cards + applied this profile
Ran Claymore 10.1 with -gser 2 option
All 12 cards has been recognized by claymore (

It started mining while still creating DAG for another cards.
I saw that some of the card started mining 28.5 Mh's (that is normal value for my cards)
Than.. Cannot create a DAG file for GPU9 and GPU3.. Claymore restarted.. since than, I was not able to start it over again
After another computer restart I was not able to boot into Windows anymore!!! Windows died!
Disconnected those 4 additional cards and here we go.. windows booted up again..
Ran DDU + restart + back to the BlockchainDriver(23aug) + patch + restart
Cards started to mine ony 14MH's no matter what.. spend like an hour playing with it.. there is some problem with applying cvddc/mclock after DDU uninstalling 17.10.2 and reverting back to Aug23 drivers
Windows installation is obviously corrupted (or the new DDU 17.0.7.7 is leaving some traces behind after uninstalling the 17.10.2(oct23) driver
Had to restore Windows installation image from backup!
So, anyone that don't want to waste the time, stay away from 17.10.2 while running 8+ cards (especially 12!)
To that reg fix..
IojkinKot has been faster, I do agree with his findings.. there are more changes but only that one seems to be relevant to me
If anyone can tripplecheck, here is exported regedit key before/after applying COMPUTE mode. Do the file comparison and please let us know the result
Applying this regedit can save 40min of installation time + another 10 minutes of manually applying compute mode for each GPU
This might actually get very important.. if AMD will stay with such a option of turning Compute mode ON in the future!!!

(6 hours wasted!)
PS: I'm NOT doing this test over again with 1709 Fall creators update !!
PS2: For those who want to say thank you, you've saved my a lot of time and pain, look down bellow the line
