Topic: Help Please - Vega 56 Mining Rig Troubleshooting - page 2. (Read 4825 times)

I have not touched the Bios.  It said it was ready to mine out of the box so I did not adjusting.  Should I go in and change the pcie link speed to gen2 like with other boards?

I hope someone can shed some light as to what's going on with my vegas.

I started with a Vega 64 and ran it on a ryzen system. just 1 card. I started with the 1100MHz HBM @ 905mV reg mod file from the reddit page. worked fine and when i started the OverdriveNtool program, it uses a much lower vcore and v-mem than oldcomer's youtube video. I left it as it is until 1 day I had some drivers issue and it never hashed at 44mh/s no matter what I did. safe mode, ddu,,,reinstall. etc I've done it all. often it would crash and the fans would max out until it was powered off by pressing the case's power button.


then i tried the morepower142 reg mod  from the OCN page. works fine but draws too much power (5 vegas drew 1172w on a 1200w psu at load) then I chanced upon the file Morepower142 modded which I used and consumes less power than the original morepower file (800w for 4 vegas at load, 5th is powered by another psu)


Feeling encouraged, i bought myself 5 more Vega 56. flashed it to v64 bios of the same brand and used the same 1100MHz HBM @ 905mV reg mod but same file gave me lots of problems and used too much power. again i used the morepower142 file.

then something strange happened. all the time I've used the dvi port on the (biostar tb250 pro) to a hdmi adapter and it displays fine. then suddenly it refuses to display anything once it reaches windows. I realised I had to connect the hdmi cable to 1 of the vegas even though none of them are in the pcie x16 slot and display graphics is set to iGPU.

What do i set for the acoustic limit? on the vega 64 in the first pc, it was default to 2400mhz. then on the vega 56s it was either 15mhz or 80+mhz
also, I copied the overdrivetool folder from the first PC to this new one. but the first time I used this tool on the new pc, it didn't have the profiles in the dropdown menu. it was only when i closed it and restarted the tool, then all the profiles showed up.

yet the very same profiles that worked on my first pc, didn't work for the 5 vega 56s. then suddenly some random settings worked.

All I know is, now it hashes at just below 44mhs and draws 800w for 4 vegas at load (5th vega is powered by another psu with no watt meter)

did you use hellae's reg mod?

i tried it and it uses too much power..i had to use the other version.   morepower142 modded.


p7 is 1222/1200 and p3 1100/1050

error 43 could be a riser problem if the card is proven to be working

have you changed the pcie speed (gen1/gen2) in bios?

using the b110 BTC+ im at 8 vegas

Thank you for all your help.  I have been manually enabling/disabling.  The issue that bothers me the most is that whenever I enable/disable card 3 it comes back on as error 43 and whenever I disable/enable card 4 my screen artifacts and the computer restarts.  However when I first boot up I can enable/disable the other 4 and if I start the miner it recognizes the 2 problem cards and will mine with them although its at about 1100 h/s each.

Cast is easier to set up as there are fewer options to configure.  My Cast start .bat file:

cast_xmr-vega --opencl 1 -G 0,1,2,3,4 -S mine.xmrpool.net:7777 -u [Your_Monero_Wallet_address_goes_here] -p x -I 8 %*

You may need to change --opencl to "0" on your setup.

-G changes depending on how many Vega's (and other cards) you have on that rig.  On a straight 6 Vega build, you would change to -G 0,1,2,3,4,5

it quicker to start up than claymore

setup a bat file specifying --opencl (0-2)
this give 1970+ h/s

Is there a walkthrough for setting up cast?  I only use claymore because I know how to set it up.

amdcleanup and ddu do the same thing i find it quicker

i cant get claymore to work  xmr stak is ok, i use cast xmr - its designed for the vegas

Is the cleanup tool better than DDU? Or does it do something different entirely?  Also could the issue be I am using claymore instead of stak?

hi
use amdcleanup tool
if you have flashed to the vega 64 bios use the registry edit file from the yourtube guide RX Vega 64 Undervolting Guide for Blockchain Drivers - Part 2.
go device manager and remember the driver key numbers under rx vega properties then details...
apply the registry edit with the driver key numbers... reboot
use overdrive nt and set the p7 1407 and 841 for voltage, memory set to 1100 and volts to 805
run cast, u should get 1700+ at least maybe 1970 depends on the individual card

i can confim the h110 PRO btc+ handles 7 vegas and rx480 no problems @ 1240w

ill try 8 tomorrow night

Since mine are already flashed should I be using the Vega 64 settings instead of the Vega 56 settings?  I am debating on starting over again tonight.

One other thing. They seem to REALLY not like warm temps. When they get to ~58C according to HWMonitor they get buggy.

All I can say is I followed that guide to the letter and with 4 vega they run at 1950. I didn't try anything extra, like flashing the bios. I would start over and see if you can get 4 running at 1950 doing exactly what that guide says. Otherwise you have no control as to base you experimenting off of.

I don't know what I am doing wrong.  I cannot break 1400 H/s no matter what settings i use.

You're not kidding.  I followed the blogspot guide I don't know why but all the other cards let me disable/enable them. 

I am currently mining and it is obvious that 2 cards do not have hbcc turned on.  They are mining at 1100 h/s and 1000 h/s respectively, however, all my other cards are sitting at 1400 or so.  I think some of my OverdrivenTool settings may be off so I can tweak them to see what happens. 

Either way I am at 7650 H/s total right now.  Can't check my energy use because I am not home but I can't imagine its any worse than the 1250w it was before. 

Honestly, I would settle for 1800+ h/s per card right now.  Thats all I ever wanted it just seemed to me that the only way to get that at decent voltage was to flash the bios.  I could go back and flash the stock bios back on to them but Really don't feel like it tbh.

Is it better to run everything off the IGPU?  You are using the h110 BTC+ correct?  I am currently plugged into the vega but I am running everything remotely right now.  

Man alive you're just not having great luck here....

I would format and reinstall. And follow that blogspot guide exactly. Don't install any other software device type software. Just AMD, and only the first option. The driver.

Maybe hold off on flashing the BIOS too. I didn't do that and 1950h/s is pretty good for just adjusting settings in Overdrive and Reg edit.

Also, maybe just start with 4 vega. I started with three. Got it working, then added in a fourth. It just required running the AMD driver install again, and then doing the reg fix for that fourth card. So if you get 4 working at 1950h/s then you can add the other two.

Can you do it all via on board graphics too? I think that makes things easier. If they crash you don't lose your display.

Yeah I only install the driver itself nothing else.  I flashed them because I wanted the softpowerplay mod. 

What is your power draw at the wall for achieving 44 Mh/s on ETH?
