Any word on amd vega hash rates?

[Permonik]

Hi,
So, how is going? My rig was stable for 72h, after that one of the card shows 0 and miner freeze. I am noticed that after 6h. Because win was still alive, watchdog was useless.
What is weird was that in the windows log was not a driver display error, but the wattman settings was reset on two cards...
So I am changed a voltage a little bit and decressed intensity and I will see how long it will be alive.

Unfortunately in my case it did not survive so well. 8 or so hours in the test one of the cards locked up. I ran cast-xmr for a cross check and it's been stable for about 12 hours now.
Today I'll try gen1 settings in the slots.

I noticed that the card that locks up is usually the one with index 1. Incidentally, that *was* the card that needed a little extra voltage to run stable at 1100 hbm freq. And I thought that I was pushing it a little hard. In the past I tried running that card as low a 900 Mhz but that did not fix the issue.

Yesterday, I rewired the board and reinstalled the drivers. Now that card is index 2 however, the card that locked up was still index 1 of stak-amd and that card was stable before.

And btw. the card in the x16 slot never locked up on me. So the x16 slot might have something to do with lockups or might not.

Hi,
My card in 16x never lock up too, but I experienced the problems every couple hours. And now, it was stable for longest time ever...
Where can I download cast-xmr? What I downloaded was only executable file and one another file...

it is closed source. you cannot download source. it's self contained and all options go on the command line. use cast-xmr --help for help.

Below you can find my experience with both RX Vega 56 and 64 version mining Monero @ 1800-2000 h/s:

Both my rigs have the same configuration except GPU type:
-  8 x GPU (8 x RX Vega 56 on first rig and another 8x RX Vega 64 on 2'nd) , Biostar B250 BTC-PRO, 8GB-RAM DDR4, SSD 120GB (65GB Virtual memory in Win10).
-  Software config: Blockchain driver, Soft PPT in registry, disable-enable display adapter after restart,  cast miner 6.0
-  Result:~1800 H/s on all 8 pcs Vega56 and ~2000 H/s on all 8 pcs Vega64
-  Print screen with the results:

https://drive.google.com/file/d/1LlhIxuc4MFVbUog50BKigv-aqV-RXuCp6g/view?usp=sharing

Coming soon: please be prepared for one of the most interesting rig (8 GPU in a semi open case with  a horn on top for hot air exhaust)

I hadn't originally planned on putting this out there, but some other asshole decided to charge a fee for this info. Fuck that guy. Here's a fix for reduced hashrate and a method for running 4+ Vega at full speed while mining XMR.

Basic Users:

1. Use the Blockchain drivers.
2. Open up your device manager.
3. Open up the "Display Adapters" dropdown.
4. Right click on one of your Vega's.
5. Disable it.
6. Wait a few seconds.
7. Right click on the Vega you just disabled.
8. Re-enable it.
9. Repeat steps 4-8 for the rest of your cards.
10. Enjoy mining at full speed with as many Vega as you damn well please. Probably.

Advanced Users:

The previously described process is a bit of a pain in the ass. Let's automate it.

New Procedure

1. Get your hands on the Windows Device Console (Devcon.exe). This will let you disable/enable devices from console.
2. Create a batch file in the same folder as devcon.exe with the following lines in it:

Code:

cd %~dp0
timeout /t 5
devcon.exe disable "PCI\VEN_1002&DEV_687F"
timeout /t 5
devcon.exe enable "PCI\VEN_1002&DEV_687F"

3. This will selectively disable/enable all the Vega cards you currently have in your system. Thanks to bytiges for noting that killing all the display adapters might not be a good idea for those using iGPU.
4. Run the batch file as an administrator at login, or whenever you lose hashrate on your cards. Enjoy never having to toggle the HBCC switch again.

Outdated Procedure

1. Get your hands on the Windows Device Console (Devcon.exe). This will let you disable/enable devices from console.
2. Run the command devcon.exe FindAll * to generate a list of all the currently attached devices and their hardware IDs.
3. Search your newly generated list for "Radeon RX Vega." You should find something like this:

Code:

PCI\VEN_1002&DEV_687F&SUBSYS_0B361002&REV_C3\6&3AAC35E3&0&000000E7 : Radeon RX Vega

4. The part to the left of the colon is what you need. Shocking, I know. Put that thing into a batch file that looks something like this:

Code:

@echo on
cd C:\Users\Mythic\Desktop\Startup
timeout /t 5
devcon.exe disable PCI\VEN_1002&DEV_687F&SUBSYS_0B361002&REV_C3\6&3AAC35E3&0&000000E7
timeout /t 15
devcon.exe enable PCI\VEN_1002&DEV_687F&SUBSYS_0B361002&REV_C3\6&3AAC35E3&0&000000E7
timeout /t 15
OverdriveNTool.exe -p0Vega0 -p1Vega1 -p2Vega2 -p3Vega3 -p4Vega4 -p5Vega5 -p6Vega6
timeout /t 10
cd C:\Users\Mythic\Desktop\xmr-stak-amd
xmr-stak-amd.exe

5. Run your batch file at startup as an administrator. Enjoy never having to toggle the HBCC switch again.

FAQ:

Q: So, Mythic, how exactly does this enable HBCC on cards 5-7?

A: It doesn't! HBCC Does nothing to improve your hashrate! Turns out the drivers are just shit and are bugged when Windows first boots up. Who would have guessed?

Q: But Mythic, does that mean I don't need 16 GB of ram to run my cards at full speed?

A: Correct! 4 GB of ram is completely sufficient!

Q: If I wanted to donate some pizza money to the broke ass college student that typed this up, how would I do so?

A: You ask the best questions! I doubt I'll get anything before more well known people/websites copy everything I just said (with no credit, obviously), but here are some addresses just in case.

Hi,
My rig is simmilar, hot air is vented out from dust proof electrical cabinet.

almost vegas are mining ETN?

It was fun while it lasted

[Shnikes101]

Was on my vacations while my small rig with 2 vega64 lc and 1 vega56 air was running happily with 5 extra nvidia cards.
vega 64 lc are running 1408/1160@875mv, vega56 is running 1408/1148@875mv.
miner is cast-xmr, perfectly stable for a week.
vega64lc are averaged to 2070h/s, vega56 is averaged to 2000h/s.
I didn't retest power consumption but it is low, my estimation is 140-150 watt for vega56 and 150-160watt for vega64lc
Now I'm back and happy that cast-xmr supports nicehash )) didn't wanna bother with etn mining directly ))

Hope you enjoyed your vacation! Ditto on the cast-xmr supporting nicehash. Nice little run we're having there.

[bytiges]

I failed to stabilize stak-amd on my rig. It just won't run for more than 2 hours per time, while using higher voltages.

With cast-xmr, on the same rig I can do 1408/1100 at 875 for both the GPU and the memory for a total of 690W off the wall for the whole rig. Real power for the cards is about 150W for 1950 h/s on average (PSU at 93% efficiency, rig MB ~50W total).

I don't see much reduction in wattage under 900mV.

I have one card requiring 930mV on the HBM for a stable 1100 MHz freq. That same card will auto-regulate the GPU @ 900 mV even when told to go to 875.

I think this is about what can be done on xmr with the Vega56. Until we can edit the memory timings (if at all possible).

I am wondering what is possible for ETH ? 44 @ 130W is what I read, but what settings for gpu/hbm and what miner is best?

130watt while eth mining is not easy with Vega. You'll need less then 800mV voltage. But maybe 1000gpu/1148mem@800mV will do the trick

I tried to switch to nicehash with xmr-stack but all my shares come back invaild??
Anyone have thoughs

[Morgon]

I bought one at $469 with a $20 rebate just three days ago!  I am kind of pissed.  I may just send it back.  Let us know if they give you a refund for the difference.  I suspect they won't.

Newegg claims they'll price-match their own changed prices within 7 days. It's a shitty policy (I've never seen anything less than 14, and most are 30), but if you say it's only been 4 or 5 days at this point, hit up their Chat.

Thanks I will do that.  Will let everyone know what happens.  Hopefully the fact that am I about to drop another $1000 with them will help

I love Newegg!  Most free shipping has only been taking two or three days.  That's pretty awesome.  I ordered my Vega Monday night and had it Wednesday!

Meh. They've gone super-downhill over the past couple of years. I buy from them mostly because Amazon charges tax and there are not enough third-parties selling at MSRP to get around it. Having been ripped for $240 (Newegg is making an exception and gifting me (only) half of that back since it was 10 days for me), I'm a little disgruntled.

Not to mention I had to return one GPU ($22 to ship!) for freezing under any sort of load. Another one crashes at extreme undervolt/overclock but stable at lower thresholds, so I wouldn't be able to send that one back.

[tf2addict]

Yeah Amazon charging tax sometimes now is making them much less competitive for some things.  And their prices really aren't that great sometimes for some things.  I don't order anything computer-related from Amazon without checking Newegg first.
