More than 6 cards on TB250-BTC-Pro / Linux

[mooreaa_revo]

Hey guys,

I just recently got the TB250-BTC-Pro and have been trying to get more than 6 cards running on it without any luck and was wondering if someone might be able to help me diagnose.

The BIOS is setup for EFI boot and I'm running Ubuntu 16.04 64bit and boots via EFI just fine. I can see all the cards from the BIOS startup screen but when I boot into ubuntu and claymore starts up it only shows 6 cards (I am trying with 8 cards).

7 of the cards are RX580s from XFX and 1 is an RX580 from Sapphire

lspci only shows 6 cards but I think others have mentioned this isn't necessarily an issue.

lshw output seems to show all the cards but i'm not entirely sure how to read it.

Other than that, I don't know what/how to check why its not seeing the other cards. Appreciate any ideas on this.

Bump as I still have not been able to solve this issue.

Just an update:

Bios does see all the cards, but when I booted into ubuntu and started claymore dual miner, it would only mine on 6 cards no matter what I did. Its hard to tell from lspci if the issue is with ubuntu or not.

BTW I did try EFI and legacy bootloaders and the results were the same. Has anyone managed to get more than 6 AMD gpus running on the TB250-BTC-PRO?

FYI I am running both the pro and non pro versions just fine with 6GPUS but I had to disable the IGPU.

Any thoughts appreciated.
