What config did you use with xmr-stak-amd? Vega56 doesn't like high intensities with xmr-stak. cast-xmr is way better for vega56 if you are not concerned with closed-source risk ))
I'm running 2016/1600 and 2016/1736. Both have the same issue. I've been following the reddit definitive guide and it mentions no problems with those intensities. At some point I remember lowering them to 1920 / 1524 but was not stable either. Can you suggest some intensities to try ? PS: yes, I don't like running closed source. I even compiled stak-amd myself, but it makes no difference vs. the stability issue above. My v56 runs fine with intensities of 1760/1760 @1930 H/s

Although the hash rates are still nowhere near the blockchain driver, I can pull 1200-1300h/s. However, I use my Vega mostly for gaming
Well, I might have had issues. Wattman does not cut it for me. I use power tables and extreme undervolting, but doing 1940h/s average on 130 W per vega56 card (flashed to 64) with stak-amd. [/quote] what settings are you using?

I am running 5rigs with 4xgigabyte vega56 cards. GPU 920mv, memory 910mv @ 1100 Mhz. 7700 hash ( 2016/1736 ). All rigs are 20+ days stable aka nonstop.
I get those speeds, but not stable. What puzzles me is that cast-xmr works fine. Are those flashed to 64 ? How are you undervolting ? I guess you're using blockchain drivers.

Preliminary tests are no good. 1300H/S like the other gaming drivers. Blockchain is what we need

Using the blockchain drivers from Aug.23. Registry undervolting. 905-905 gpu/hbm and 1408/1100 freq on gpu/hbm.
Reducing the memory speeds does nothing. Stak will hang again.
Now, anyone has stak-amd running well on similar hashrates or are you all using some other miner ?
How low are you bringing the memory speeds? 1100 seems high for a 56, and high to run XMR in general. I don't see much improvement over 950, and run mine at 920 getting about 1900h/s (edit - unflashed - I didnt see any benefit flashing to 64, either) Flashing to 64 gives you 64 cores and 1100 memory speed. For me I cannot reach 1900 on stak-amd without flashing. Are you using stak-amd or something else ? Are you undervolting ? What is your power usage? Edit: do you mind posting your full config?

But these Vega cards are sooooo expensive! I will be sticking with the 1080ti's for the foreseeable future. How long will it take to see ROI with the Vega's?

I also had a lot of problems with stak-amd... I'm using 8xVega64 and after a while with stak-amd one card goes to 0h/s and then the whole rig just shuts down. I switched yesterday to cast-xmr, it seems more stable and until now I had no crash/shut down. I also noticed if I'm connecting with teamviewer or opening some applications like GPU-Z, the cards are starting to mine with a lower hash rate same like the HBCC was deactivated.

Exactly my issue. One card hangs then the rig follows shortly after. I also see that any diagnosing utility must be started beforehand or it takes forever to launch and has a high probability of hanging the rig. Castxmr seems less susceptible to this compared to stak-amd. Like I said, lowering the speeds of HBM does not help. I go as low as 900 and still hangs. BTW, I'm using sapphire bios. Might be that it's not the same as other makes (gigabyte/msi etc). One thing I noticed, is stakxmr uses a little more power per card (about 5W). Running out of ideas to try.

I found why my rig was shutting down (I think), I changed the power plan, monitor -> turn off - never; HDD -> turn off - never, and so on... Without these setting many times after 30 - 60 min since I closed the connection thru teamviewer, my rig either was shutting down or froze. I see now it's working, hope this was the issue.

Can anyone help me with making a batch file that would make mining maintenance almost fully-automatic? I want to "glue" together script #1: cd %~dp0 timeout /t 3 devcon.exe disable "PCI\VEN_1002&DEV_687F" timeout /t 5 devcon.exe enable "PCI\VEN_1002&DEV_687F" timeout /t 3 OverdriveNTool.exe -p0Vega56-1 -p1Vega56-2 -p0Vega56-3 -p1Vega56-4 -p0Vega56-5 -p1Vega56-6 -p0Vega56-7 -p1Vega56-8 timeout /t 3 start /d "<yourdirectory>" xmr-stak-amd1.exe start /d "<yourdirectory>" xmr-stak-amd2.exe start /d "<yourdirectory>" xmr-stak-amd3.exe start /d "<yourdirectory>" xmr-stak-amd4.exe start /d "<yourdirectory>" xmr-stak-amd5.exe start /d "<yourdirectory>" xmr-stak-amd6.exe start /d "<yourdirectory>" xmr-stak-amd7.exe start /d "<yourdirectory>" xmr-stak-amd8.exe and script 2 taskkill /F /IM xmr-stak-amd1.exe taskkill /F /IM xmr-stak-amd2.exe taskkill /F /IM xmr-stak-amd3.exe taskkill /F /IM xmr-stak-amd4.exe taskkill /F /IM xmr-stak-amd5.exe taskkill /F /IM xmr-stak-amd6.exe taskkill /F /IM xmr-stak-amd7.exe taskkill /F /IM xmr-stak-amd8.exe start /d "<yourdirectory>" script1.bat with the following "code": if hashrate of xmr-stak-amd1.exe <1700 or xmr-stak-amd2.exe<1700 or xmr-stak-amd3.exe<1700 or xmr-stak-amd4.exe<1700 or xmr-stak-amd5.exe<1700 or xmr-stak-amd6.exe<1700 or xmr-stak-amd7.exe<1700 or xmr-stak-amd8.exe<1700 execute script 2 or embed script 2 lines in separate instance in here else: keep it running in that loop anyone good with batch?

@MoneroCrusher: your best bet is to parse the web page from stak and issue the commands. It's perhaps easier with a small program than a batch.
The problem is that when stak-amd hangs you need an external device to shut down and power up the computer. A simple script won't suffice.

I've raised the voltages to 920mV and 930mV on the problematic card, both on the GPU and HBM. I had the always on settings already, but had overseen the linkstate power management on the pci-e bus. Let's see how it goes. I'm up 30W from the wall (running at 720W for the whole rig of 4 vega56).

actually when a stak instances freezes I can close it without a problem, computer stays online

Yes, turn off Crossfire.
Can crossfile be on with no monitor attached ? Probably not, but the green light means the card is in standby mode. This usually happens when crossfire is on...there may be other reasons.

Anyone got experience with 4+ vega on GA-970A-DS3P (/FX/rev2.*/) mobos? I already have ddr3 ram/fx cpu and those are the only not overpriced 5 pcie slot am3+ boards, but they had issues with 3+ gpu detection and hashrate drops on certain configs =\
