https://openpool.tech/ is brand new - only a couple days old.  It is the official mining pool of CRC.  I moved my rigs there to help get it going.

In my opinion, based on how this coin mines compared to others I mine, it needs to be in the $20ish range to be worth mining for anybody concerned about current value.  Of course if the goal is to accumulate this coin, current value isn't as important.  We'll soon see!

Alright, my board arrived a day early and I was able to swap it in to my rig.  It worked with all 8 1080 TI cards right off the bat, no problems.  I didn't do anything beyond the usual adjustments with the BIOS, so I think I know the problem.  My guess is that a switch to these m.2 adapters is all that you all need:  https://www.amazon.com/EXPLOMOS-NGFF-Adapter-Power-Cable/dp/B074Z5YKXJ/ref=sr_1_3?ie=UTF8&qid=1516773409&sr=8-3&keywords=explomos+m.2+adapter

On the MSI motherboard I referenced in my previous post, these m.2 adapters had some luck getting more cards recognized than people with different adapters, so I think these are the way to go.  The same adapters are available on the UK Amazon site, but under a different brand name.  I can't think of what they are called right now.

Good luck!

just under 1/2 of a coin if your card works the same as mine.  I paced at 2.4 coins in 24 hours with six 1080 TIs.  I have yet to mine a full 24 hours though, so just an estimate.

Great, I have this board arriving on Wednesday to replace an MSI board that was supposed to support 8 GPUs but doesn't, at least easily.  Hopefully my hardware will work and I'll have ideas to post...

By the way, the ArcPool port # appears to have changed since the OP.  It is now indicated as 31010 for RAP on their site, though maybe the original works too?  I'm currently using 31010 and it seems to be working fine.

2.4 coins expectation in the first 24 hours of available mining with six 1080 TI GPUs.  I have other things to do...

The pool I was on was averaging about 10+ blocks/hour though, so at lease there was some action

I also bought this board assuming it would run 8 cards

Fact is, I did get 8 cards up and running, but it was unstable, the 8th card kept falling off, and even with 7 cards running, my rig crashed way too often to make it worth the trouble.  This is on Windows 10.

I do, though, have six cards running and all appears to be stable.  I went to bed last night with six 1080TI cards crunching ZEN and it is still running now, about 10 hours later, so at least a stable six-card setup is possible, even if you can't get the m.2 slots to work reliably, though it is also possible that I just got semi-lucky.

It wasn't easy.  I had to go through quite a lengthy process to get it going.  Here's what I did:

First, go through the standard motherboard BIOS modifications.  Without BIOS mods, this won't work.

Next, with the CPU to the left, label the six PCIe slots 1 - 6.  I added one card at a time in this order:  1-4-2-6-5-3.  Crazy but this is what it took.  The manual says the full sized slots should be used first left to right, but that didn't work out for me.  After each card was added, I would check the device manager to make sure they were all recognized without error.  If I had an error, I would reboot without the last card, then reboot again after adding the new card to a different slot.  That's how I ended up with the 1-4-2-6-5-3 progression.  Your progression may be different than mine.

Finally, to get the 7th and 8th cards "running", I used the m.2 slot to the right first, then the one next to the CPU.  Again, not what you would expect, but that's the way it was for me.  Ultimately, I removed both m.2 adapters anyway.  I did get lucky and bought the white explomos adapters (looks just like the Lattcure ones from Amazon UK, so I assume these are the US version), which appears to be important to have any shot of cards 7 and 8 working.  

After each card was successfully recognized by Device Manager, I also powered down and booted up two or three times before adding another card.  I could tell by differences in each boot procedure that my computer was still sorting out the new card.  After three or so boots, it was reliably repeating the standard boot procedure and I moved on to the next card.

Important:  My rig looked like it had locked up several times during the process.  It was simply working at sorting all those cards out, and it took a very long time.  After adding each card, if your screen goes blank, the monitor goes to sleep, the circle of dots on the login screen freezes, etc.......just go take a walk or something.  Don't mess with the power button.  Leave it alone and let it do its thing.

Finally, this is all relevant if you own this board and can't return it and have no other options.  Do not buy this board for mining if you don't already have it unless you hate yourself.

How often do the AUR coins get converted and paid out from mining on the Unitus Mining Pool?  I got paid out 60+ coins after about 7 hours of mining, but nothing after another 24 hours.  At least 8 blocks were worked during that time that I saw, probably more like 10 or 12 blocks.
