Any word on amd vega hash rates?

[oskar_n8]

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.

what settings are you using?

There's a new AMD driver (17.40) released yesterday.

Supposedly it incorporates the fixes from the blockchain drivers and can do more than 4 cards per rig.

The AMD page is http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Pro-Crimson-ReLive-Edition-Beta-for-Microsoft-Windows-10-Fall-Creators-Update-Release-Notes.aspx

Or just search for crimson 17.40.

I think that this driver is primary focused to workstations with fire pro and so on...
This is not what we are looking for.

Sorry, linked the wrong driver. The correct one is: http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-Beta-for-Windows-10-Fall-Creators-Update-Release-Notes.aspx

Installing on a test rig.

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?

we don't care for ROI. We do it for the glory!

All flashed to 64. Blockchain 23august drivers. Undervolt via OverdriveNTool.

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:

Code:

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

Code:

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":

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 =\
