Man I am about to throw this damn vega rig against the wall.  I'm not a rookie, I ahve built 100's of miners and actually have over 200 running right now but this vega, man it's testing my patience.

Biostar TB250+
8GB Ram
SSD
Windows 10 1704? Whatever the newest is
Blockchain drivers
1600 Watt titanum EVGa

All risers and equipment tested on 7 rx 580 cards and operate without flaws.

7 x MSI Vega 56

pull 580 cards out, add
1 vega - works good
2 vega - works good(disable HBCC whatever that setting is sorry paying from memory)
3 Vega - Pixalation and frozen

I can get system to see all 7 cards but cant get past 2 to work.  Any idea what the hell?  Thanks in advance guys!

What do you mean by "bad values"?  I get hash speed drops within a couple of minutes on my Vegas.

Also, I cannot for the life of me get the powerplaysoftmod working for some reason.  I noticed that the reg file spit out by OverdriveNTool was slightly different (different number of rows/columns) compared to the reg files posted in the Overclock.net thread.  The files posted in the overclock thread allow me to boot into Windows but as soon as I try XMR, it crashes, but it works fine with Eth mining.  The files spit out by OverdriveNTool more often than not causes Windows to not boot, so I have to boot into safe mode, load the stock reg file, then reboot, back to square one.

Anyone can provide me with some advice on what to try?  I'm only doing this because OverdriveNTool is not allowing me to change voltages, only clocks.  Running blockchain driver on a Vega 56 and 64, and currently using MSI Afterburner to change voltages since it actually works.

How use Cast XMR with Mining Pool Hub?
I'm receiving this error

Tried different ports with no success?

If my recent experience with this board is any indication, you might want to verify that Windows Event Viewer isn't throwing a ton of PCIe Bus errors

change the -CL from either 0 to 1 or 2.

I'm having the "one card drops to 0 h/s" issue too.  I get that error then the whole rig stops hashing with the GPUs even though XMR still shows activity.  Eventually the system crashes when i try to quit the miner and I have to reboot.  It happens after 45-60 mins of mining almost every time.  I'm going to reinstall windows again but this issue is making me rethink my XMR mining.  I might end up ditching this project and going with asics if I cant get it working.  Has anyone solved it?

Linux Version?

I am also looking for a Linux version.
