Hi, I'm having troubles with win 10 as well.
I've tried a bunch of different combinations, but I'm not able to run 6x470 with modded BIOS, only 4 of them are working.
On default BIOS everything is ok, but crimson 16.12.2 can't recognize modded BIOS, so I had to downgrade drivers.
I'm trying a couple of drivers, but all with the same problem, only 4 with modded bios can run.
Any advice would be highly appreciated.
Use 16.9.1 drivers, or atikmdag-patcher-1.4.4 for other versions.
16.10.x work without patch too, not sure about 16.11.x
Thanks, I thought that patcher is only for latest crimson drivers. I will try it over the weekend and inform here how everything went.
For now they are working on 16.10.2, 150 total for eth using 780W.
Hope that I will make it work on 16.9. because during testing I saw that this version has absolutely best power consumption.
Thanks for help, everything is ok now and all cards are working with modded BIOS. I've received 30 RX470, but they have different memory chips, three different ones. No need for patch in win 10, just a little patience.
All 5 rigs are running at 150 MH, but power consumption varies, from 780 to 900W, depends of memory chips.
