AMD drivers only support up to 8 AMD cards. If you want >8 GPUs, you can get there with nVidia cards

I'm pretty sure Ive seen people use more than 8 AMD cards on windows before... there's also multiple posts in this forum regarding just that with people having no issues  Lips sealed

So I'm using an ASRock H110 Pro BTC+ with 3 PSU's i had layin around (2x 1k W + 1x 1,6k W - i know it's an overkill, but didnt have the cables/slots otherwise).

Thing is that it's only detecting 8 of my RX 580's. Although the 9th will show up as VGA Controller, while the first 8 show up as RX 580's.
I've read that I'll need the 1709 update for Win 10, which i am currently using (Win 10 Pro, if that matters), aswell as 17.11.4 AMD drivers, which I'm currently not using.
Will changing to those drivers fix my issue by any chance?
I'm currently using the Blockchain beta drivers because those gave me 31 Mh/s on a single card with OC. However for some reason after connecting the second one those cards each gave me about 20 Mh/s with OC.

I will uninstall the blockchain beta driver with DDU and get the 17.11.4 one, and I guess setting my cards to "compute" in the radeon settings will also fix the low hashrates, but will that also fix my detection issues?
I havn't changed any PCI-E settings in my BIOS yet, might give that a shot aswell.

So if anyone could assure me that one of the steps mentioned above will fix my issue, please shoot. Tongue I have to drive my ass out into the alps so it would be nice to have a strategy before I freeze to death. Grin But hey! 5-8 °C room temperature and 0.06 $ kWh - shouldn't be complaining.  Tongue

Was already thinking about just using SMOS since apparently there's less hassle with card detection, however I only have one drive left and I guess I need two for flashing.
Also, I've added the first gpu to the 16x slot, then started filling from top to bottom since ASRocks mining guide says to do so.

Cheers!
