Hey guys, doing my first Vega setup here, I've had a lot of experience with Nvidia rigs but first time doing an AMD one and as expected it's been going rough so far..

So the config is the following:
Gigabyte GA-Z270P-D3
1x EVGA 1000GQ + 1x EVGA 850GQ
Pentium G4400
4 GB DDR4
128 GB SSD
6x Vega 56

I had no issues with the Mobo, recognizing all 6 cards right off the bat. I installed whatever is the current version of Windows 10 Professional (1709) from the official media creation tool, set VM to 80GB and followed this guide:
https://vegamining.blogspot.com/

Now, I've been facing a bunch of different problems - first, when I run my script to enable/disable GPUs - either through the .bat file, through Powershell and I even tried through Python - i get a BSOD most of the times and have to restart. In the few times that this part worked, I then apply the Overdrive settings and start XMR-STAK which initializes properly but then hangs almost immediately.

I did a few more attempts, flashing the Vega 64 BIOS and following this guide but ran into similar issues:
https://www.reddit.com/r/MoneroMining/comments/74hjqn/monero_and_vega_the_definitive_guide/

The only success I had was doing something between the two guides - keeping stock BIOS, applying the Wattman settings from the above guide for Stock BIOS and then applying overdrive settings on top and running XMR-STAK. I know it makes no sense but that was the only thing that worked and was running stable for 8 hours but with terrible power usage - 225+W per card. That's why I decided to start from stcratch and try the Vegamining guide again but ran into the same issues as before. So essentially I've been goin in circles and am highly frustrated..

Any help will be greatly appreciated! As well as any advice on which guide do you think I should follow with my rig configuration.

How well does Vega mix with RX5xx GPUs?
Thinking of switching some of the weaker cards for my new Vega's while I wait for the new mobo. How well do they actually play together? I'm using the blockchain driver already...

I'm also 4x vega 64's, 1990 or so (though i am on lc if that matters).  You can definitely get that wattage down if you care.  I had zero problems with the reg mod (from hella).  Definitely worth a shot if you have an hour or two to spare. 
I've yet to test the new stak, but want to get that cpu up and running as well soon.  Hopefully push out another hundred h/s and check if it's worth it. 

FE liquid price down @799USD on Newegg

Thanks but what driver are you using?

Does anyone have experience running VEGA 56s with RX 470/480 series cards? Please correct me if i'm wrong but from what i've read the series makes a difference too.

Have anyone tried mining with vega frontier edition? Wondering if the extra ram helps with running XMR?

No bios or registry modes.pure 56 with casr and gandalph guide

its a faster card but the normal third party tools eg afterburner etc don't fully work with it, ie control voltage also drivers limited to blockchain and FE builds so people would say not cost effective

lets ask for the third time - is anyone getting errors like this: "GPU COMPUTE ERROR" and how do you stop it - by lowering temps on a card or by reducing memory clock?

maybe you can try a few changes and report back ? I did see some of these errors when pushing the cards beyond their limits. Don't remember what I did exactly to fix them.
