Guys, Does anyone know if you are able to run 12x rx580 or 12xgtx1070 in windows with claymore without issues?
I know that ati released new drivers that would allow you to do this for rx580, but I am not sure, and certainly not sure about nvidia.
I am right now using h110 pro btc, but planning on getting b250 mining expert motherboard if that help.


I tried 9 MSI RX580 cards on the ASUS mining expert mobo with the latest AMD driver and Windows10 and yes, it does recognize all the cards but I was not able to get it to run stable. Also the hashrate was not great, with the latest AMD driver, I got only 27-28 Mh/s with the same cards that got 29-30Mh/s using the blockchain driver. And it was very unstable, lots of openCL hang errors and a few hard windows crashes(completely frozen) that required manual reboot. So the latest driver is not quite ready for primetime. Went back to the blockchain driver and only 8 cards and my rig has been up with no hard crashes for over a week now.

I am having a very weird issue. I just set up my 2nd miner with the following specs

ASUS Prime Z270-A mobo
8GB ram
5 MSI RX580 Gaming X 8G GPU
SSD drive
Windows 10
Blockchain driver
1000W EVGA PSU gold+

All pretty standard stuff. I flashed all the GPUs and updated bios on the mobo and turned on 4G, etc. Everything is running correctly while it is plugged into ethernet. I ran Claymore 10.2 and all 5 cards shows up and running with around 29.5Mh/s. I let it run for about an hr and all is good. I then switched the network to a wifi repeater and plugged the rig into the wifi repeater via ethernet and let that run for 30 mins and everything is still fine.

So now I pick up the rig and move it to another location to run it as headless with the wifi repeater next to it and all hell broke lose. Claymore hangs with GPU0, restart miner messages. Figured out with card is GPU0, unplugged. Thought maybe it was a bad riser. Reboot, same thing. GPU0(represented by a different card now) hangs, restart miner. Unplug again and reboot, now getting GPU0, GPU2 hang errors. Also claymore takes forever to startup. When all 5 cards were running, it was drawing about 750W at the wall. So definitely not a power issue. It had the same hang issue when I only have 4 cards plugged in.

I haven't moved it back to my bench yet and plugged the monitor back in. But does going headless with Win10 affect how claymore sees the cards? Any ideas?

Thanks in advance!
