Thanks!

No, I didn't try HiveOS. Now, the rigs are very stable and powerful, I don't want to experiment now as the thing is working without issues. Experimenting with something that i have 0 experience with could give me big downtime so there is no reason to try it now.

I am running 7x Vega for 2 reasons:

1) The power supply output is 1200W and 7 Vegas fit this but 8 do not (maybe cryptonight Heavy could do but I want to be flexible, I work on the drilling rig 28 days on/off and need total reliability and flexibility when I am away)

2) Power distribution board has 17 ports, I am using 14 ports for Vegas and 3 ports for motherboard. I never really measured the amperes through these cables, it can probably work with 1 cable, but I never bothered

If any of your clients have questions, you can always PM me here on the forum and I will try to provide answers.

These motherboards work fantastic with blower style cards like reference Vega, as there is no need for additional fans. I just plug the rig into custom made air duct and all hot air is exhausted direct out of the room. It is so easy to cool, unlike aftermarket coolers which require incredible airflows.

The BIOS of these motherboard is so complicated for me, I can't really understand anything, there are options that I have never seen on normal PC motherboards. It is not required anyway as the motherboard worked straight away, but surely, it is tempting
