Any word on amd vega hash rates?

How much ram need for 2vega? Is 4gb ok, with enough virtual memory?

[bytiges]

Hi,
For now, rig is still stable for 22h and all 9 cards mining.
If its hold another 22h I started to thinking that the main issue is card/riser inside 16x slot... I had gen1 on all slots...
Gpu is 905 and mem 900. On the wall is about 1350W for whole system...

I removed the card from the x16 slot too. 2h stable now. Let's see if it holds.

[teuflor]

i tried to undervolt only with overdriventool + 23 Aug driver.

Result 860W with 3 Vegas... sucks! 1400mhz @ 900mv

with the reg mod from the ultimate how to, my 1709 windows wont reboot

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Outdated Procedure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.

          ETH: 0x74Ed2CA095Dd3aE98D88d5ca1dDb77E752152938

Thanks to you, my mining speed went up from 8900-9000 to 9500-9600!!!

Yes 4G is OK

I finally got xmr-stak working.  Getting 1717 H/s with xmr-stak-amd on my Vega 56 after doing the "disable GPU then enable GPU" trick in Device Manager.  Before the trick I was only getting 1170 H/s.  This is with 4GB RAM.  Hope AMD can fix this issue with a new driver soon.  Cast_xmr is getting 1713-1734 H/s, basically the same.  Note that this is with stock Wattman settings.  By setting memory to 950, frequency to -30%, and power to -20% I have hit 1870 H/s!  Excellent.

Now I just have to script the GPU disable/enable after boot.  It's great that I can still use only 4GB of RAM.  The only unknown at this point is if Wattman is going to keep resetting back to defaults.  Wattman sucks.  It desperately needs profiles.

Anyone tested tune for better effiency, to lower power or temp/loudness? Whats your results?

(those are the MSRP price), sad for those who pay $600+ per card few weeks ago.

Notice that only SAPPHIRE are selling the cards at thos price, other brands still have high prices...

I just paid $469 for the Gigabyte Vega 56 with $20 rebate.  It is now $419 and still has the $20 rebate.  Limit 1 per rebate of course.

I wonder if these prices are the new normal or just a temporary dip?  I plan on picking up 3 more cards in the next week.

I didn't like the blocky form factor of the Vegas at first but I do now.  They look a lot better in the rigs than the hodgepodge of fans and heatsinks of the RX and Nvidia cards.  The Vegas actually look slim compared to RX580s.  The blower fans are way too loud though.

Has anyone switched off Monero and onto something else?

Monero has been great for me the last few months. Just curious if anyone has played with any coins besides xmr or eth

Edit - just looked at whattomine 1080ti. My revenue off monero is still beating this card. So I think I just answered my own question

Yea well, monero with any other gpu or cpu is just stupid But it seems ETH dual mining with polaris or gtx 1070 is closing on to vega monero. Then there is zencash which is better than zcash and has potential.

Zencash seems to be the hot Nvidia coin lately.  1070s should be dropping in price a lot between the Vegas dropping and the new 1070ti coming out.  I am going with Vega cards for the time being as they are more flexible in what can be mined and the Monero profitability is awesome right now.  Though I kind of waiting to see what happens with Bitcoin Gold.

almost vegas are mining ETN?

[carlo_0000]

at what speed and volt are you running vega56?

it put the clock on 1222 but i notice it run around 1312 -27power limit (i guess not enough yet)
and undervolt 975mv did not try lower yet

did someone try the slowest clock without hash drooping?

Is like amazon, diferent sellers, all you need is choose NEWEGG as seller and thats the msrp price.

ho nice last version of msi afterburner is working

i have 2 vega computers   but on one the power setting in afterburner is not available    the setting are the same

Hi,
For now, rig is still stable for 22h and all 9 cards mining.

Gpu is 905 and mem 900. On the wall is about 1350W for whole system...

I removed the card from the x16 slot too. 2h stable now. Let's see if it holds.

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.

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 ))
