Any word on amd vega hash rates?

[rednoW]

I have an issue with my setup.  Can someone point out what I'm doing wrong (my first setup).

I'm getting very low speeds on my 2x vega 56s regardless how I set it up.
I've tried the following with the results:

- index 0 only: 1 thread per GPU 2016 results in 600H/s
- index 0 only: 2 threads per GPU 2016+1600 results in 236H/s
- index 0+1: 1 thread per GPU 2016 results in 1175H/s
- index 0+1: 2 threads per GPU 2016+1600 results in weird rates ID 0 = 132, 1 = na, 2 = 221, 3 = 853 and 1 and and I get CL_MEM_OBJECT_ALLOCATION_FAILURE

"platform_index" is set to 1 (doesn't work when set to 0)
Sometimes xmr-stak-amd freezes when setting up 2nd "Device 0 work size 8 / 256" or sometimes on Device 1

My setup:
ASRock H81 BTC R2.0 mobo with G3260 CPU and 4GB of RAM running Win 10 64bit
Both cards are connected via risers (PCI-E #2 (long) and #3 (short) are in use out of 6 total) and powered by 1000w EVGA gold
I am connected to the onboard HDMI for monitoring
There are no HDMI dummy dongles in the Vegas
Running blockchain driver v17.7

Anything obvious pops up?  I'll try disabling onboard video and connecting the monitor to one of the Vegas, but can you see any other issues with this?  Pointers perhaps?  

All of this is running on default 1580MHz/800MHz speeds (haven't tweeked any Wattman settings and HBCC is off)

Thanks a lot in advance.

1. add virtual memory, 16gb per card
2. Make sure you use 23aug blockchain driver
2. re-enable both cards in device manager before mining
3. use cast-xmr miner
4. make sure your temps are below 70 degrees (both gpu and hbcc)

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.

Thank you very much.  increasing VM fixed the error message, now running consistent 1975 h/s per card without tweeks using default cooling on the blockhain driver.  Still connected to onboard video (Intel).  Wondering what I'll get with HBCC enabled.  For some reason it crashes my AMD Settings prog as soon as I try to change it to anything.

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...

Excuse me for being a newbie, I am pretty tech and hardware literate, but when it comes to creating batch files and software coding I've had practically no exposure beyond some basic HTML for websites.

I found this:   https://pastebin.com/Q0rGa0QS  

I think that's a complete batch file that I'm looking for, but I'm still trying to figure out how to properly edit it to function completely automatically with castxmr.   It's set up to run with xmrstak.  

I got it to work and it starts castxmr, but it doesn't load my payment address when it starts and it also doesn't restart on it's own when the hash falls.

You create a separate Start-Cast .bat file with your payment address (see the Cast thread for running the --help command).

Then you change one line in the PasteBin file:

FROM THIS:

start "XMR-STAK Unified" xmr-stak.exe --config config.txt

CHANGE TO THIS:

start Start-Cast.bat (or whatever you named your Start-Cast .bat file)

The PasteBin file points to your Start-Cast .bat file, that's all you have to do.

I still can't reach the power draw of 130w for vega 56 like hellae

The reg mod for the flashed vega 56 is causing gpu core to run at 1410mhz and even if I reduce it to 1210mhz it still draws 977w at load for 4 cards. Idle is about 130+w.
I'm using the common setup of g4400, 4 Gb ram.

Another thing is, i can't change the hbcc ram level at all. The slider is Greyed out and stays at 97xx mb.

You will need 8gb of ram to activate hbcc using Wattman. I've heard it can be done by disabling each card in device manager then activating again but I haven't tried thisywelf as I had bought an extra 4gb before that fix was found. Still not attempted the reg mod for the power consumption yet. Currently running 4x Vega 64s at 900W 1950h/s per card

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.

I run one Vega 56 with 3 570s and 2 580s, no problem.

How? I'm mining ethereum at the moment and the best i got is 170w for vega 56 flashed to v64 bios (difference between load wattage and idle)

If i lower the core voltage it increases the power draw.

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.

Is mining ether more power hungry than mining xmr?

[KaydenC]

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

You doesn't need HBCC for high mining speeds. Old tricks with HBCC was used as switching HBCC was causing card re-enabling that solves internal driver paging bug. The same can be done with just disabling and then enabling the card in device manager.

using cast xmr sometime now, so far so freakin good ! got free electricity so i follows gandalph guide for 2050h/s (running 56's) at -10% 990 ram and +13% power. anyone managed to find a sweet spot for bigger gains but higher power draw? experimented many many settings but with no luck... best of is 10mins at 2110h/s but it crashed or pixels screen

Is that with the 56's running the 64 bios?   It wasn't clear to me if that was factored in at all. 

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

Thanks.  I was able to edit that batch file and it's working well enough.  I seems to hang and have a few errors when I've tried to execute it though.  Like one time it disabled the cards, but then only re-enabled one of them.  It doesn't happen every time, but I'll keep working at it to see if it's on my end.

I'm still running at full speed now after a whole day of mining.  I have nicehash and a couple nvidia cards on this board, but if I run any of them it kills the speed on castxmr.  It reallys sucks, but it appears you gotta keep your AMD cards on a dedicated board running just one algorithm if you have Vega's.  Every time any other nicehash window pops up I notice the decline.

This is disappointing because I have an ASUS B250 Mining Expert board in the mail right now and sold my Biostar to my friend.  It supports "19" cards so I was hoping to be able to throw all my cards onto this one board.  

How many Vega's have people successfully ran on one machine?  Most builds I see comprise of only 4-6 Vega cards.  

And is there any news on a updated version of the blockchain drivers coming in the future?  I've tried a few of the official releases that supposedly added the compute instructions, but they had really bad hashrates.

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

They are now $700USD on newegg. Assuming vega 56 does 1800h/s at $400, if these do 3000h/s they will be worth $700USD.

It has double the ram, but does it double the hash rate, or does it become compute bound first?

I agree software control might be tricky, if it does 3000h/s I dont mind

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?

[Amigo9881]

 

Hey everyone, i am new to this forum. Out of 6, one of my vega 64, when installed BC driver and after running PP registry, went full throttle on fan speed, and windows error shows up showing gpu temp overload and my system hangs. Its just with one card, no matter what i do, on normal driver it works fine, but on BC driver its creating this problem. Is my GPU faulty, should i return it ?. Please help

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.
