I see huge influx of people here and some are way more clueless then the others...
so here some tips for you there, mining with Polarises on Win10:

1. make sure you have sufficient power on your PSU(10-20% spare from the peaks)
Note: properly configured polaris should be just below 150W on dual ETH
2. molex power to raisers is probably the most common point of failure (bad/unstable hash, card disconnects, crashes, and such)
Note: it seems there's no such thing as bad raiser, only bad contacts in power connectors
3. disable all you can via Group Policy, especially windows update and drivers update
4. use latest DDU and install 17.11.1 driver, pointing manually from Device Manager to the dir with unzipped driver
Note: Do not use blockchain beta driver as it has some issues with latest API and also doesn't support more than 8 AMD GPUs
5. set compute mode for all GPUs. here's the example for dev0 (special thanks to @ober for that):

Code:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]
"KMD_EnableInternalLargePage"=dword:00000002

6. Flash bios mods with tighter straps. Look for PolarisEditor v164 with "one click modify" bios timings and use atiflash without gui
7. Use overdriven tool (RX5* Polarises normally do well on 1180 & 1950-2150 @ 850mv, RX4* may need lower core freq)
Note: do not use AB.
Note: do not use claymore for core&mem&fans control
8. Use sysinternals autologon and built-in MS task scheduler
9. make reboot.bat and set "-r 1", as restarting miner most likely will NOT work

Bonus:
* I'm using RealVNC for remote access - flawless
* you may find useful: display dummy dongles and usb watchdogs
* and as always openVPN is your friend

If I just made your life easier and increased your profits PM me and I'll give you my ETH address:)
...or you can just find it in my profile yourself

Hi. Excellent post, but I have a question:
Why not use Claymore for voltage/frequency control - it works fine? Overdriventool on the other hand sometimes doesn't set voltages for 1 of the cards.
AND my main question how do you control fans???
(claymore makes them go up and down, overdriventool doesn't control fans on some rigs and doesn't control voltages on some random cards)

I also use Claymore for settings. On Sapphire RX580 cards is ok with everything, but i have also a MSI Gaming X RX580 and the fan is starting randomly based on the card temperature. So i use Speedfan from http://www.almico.com/speedfan.php to set a stable fan speed on MSI.
