SRBMiner Cryptonight AMD GPU Miner V1.9.3 - native algo switching

[GKumaran]

Dok & guys, quick one please:

is the "heavy-x" algo needed to mine x-cash giving the same sort of hashrates as the other heavy/heaven variants (i.e. approx 1750 h/s on Vegas)? I can't seem to find much on this. The Excel spreadsheet does not include any community contributions for that specific algo...

Yeah x-cash uses heavy-x algo.
I made this chart to keep track of my hashrates.

no.

Can we use "persistent_memory" in the CMD Line?

[Pennywis3]

Doc, do we know why TR has such different power consumption compared to other miners?
Are you working on this? Well, I hope something similar can be implemented in your miner too

The miner has stopped working bug is getting pretty annoying very quickly.

[GKumaran]

Modified the startup code from wildrigminer to run SRBminer. Can others with the "miner has stopped working" bug also test it out and suggest any other alternatives to this issue.

start_miner.bat

Code:

setx GPU_MAX_HEAP_SIZE 100
setx GPU_MAX_USE_SYNC_OBJECTS 1
setx GPU_SINGLE_ALLOC_PERCENT 100
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_MAX_SINGLE_ALLOC_PERCENT 100
@echo off
cd %~dp0

cls

:loop

for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set LOGTIME=%dt:~0,4%_%dt:~4,2%_%dt:~6,2%_%dt:~8,2%_%dt:~10,2%_%dt:~12,2%
set LOGTIME=%LOGTIME: =%
set LOGTIME=%LOGTIME:,=.%.txt

No, but that parameter is anyways only used when old mode is enabled, and i think it became.. useless

We all know why, but we - the others - who don't have enough knowledge with GCN asm, probably can't do much atm.

How to write startup_script: -cclock, -mclock, -cvddc, -mvddc and run it?
Thank.

First download a Claymore miner, then try those commands.

I asked about startup_script.

Same here , i switched to another miner , until this will solved

thinking of bios modification to my ref vegas 56. Can someone please (that has done it) tells me a good stable config and the pros/cons of all this? does it worth it? already stable 56's with 1880h/s each

Maybe you guys could give a little more info, because i can't really help you if you say 'it s not working'.
I have rx550,560, rx470,480,570,580 4g and 8g. Vega56 and its working on every rig. Also i guess it works for the majority because this forum thread would be flooded with 'not working' messages.

SRBMiner does not have cclock, -mclock, -cvddc, -mvddc parameters

btw , i use latest amd driver . i had issues with 18.6.1 and then i updated to the latest and no issues found , for ex rig frozen or dropping hashrate .

You cannot mod the BIOS of a Vega 56, you can only modify PowerPlay tables for Vega.  Alternatively, you can use Win10 and the latest beta version of OverdriveNTool 0.2.8beta1.  Also, you can swap the Vega 56 BIOS with the Vega 64 BIOS.  But you cannot mod a Vega BIOS.

[Prolow]

I had an issue where my vega rig crashed after about 8-9 hours when I upgraded from SRB 1.8.0 to 1.8.2, I was using 18.5.1. After that I tried installing the 19.4.1 and install all the windows updates, and now it seems to be working as it should. However I do get a few shares rejected due to low diff, not really sure why though.

HEllo thanks for your reply, yes i meant swapping bios..do you know any drawbacks like high temperatures etc or all just the same, my problems is that im living in a country with high ambient temps so i cant bear to set the fans any higher already i have a vega fan headache.already using overdrive (older version) to config vegas everything seted up via vega mining guide and powertable

[doktor83]

Because some reported 'random miner crashes not related to gpu crashes', i made a little tool as a workaround, until i find the bug(s) and fix them.
This tool serves as a replacement for scripts you can set up to monitor the miner process and start it if it's not running.


SRB-RESTARTER

Only 3 parameters :

--interval value_in_seconds [def. is 10]
Specifies how often to check is the SRBMiner process running

--instance number
Use it if you run multiple SRBMiner instances on the same machine, example is below
You must use the following file naming :
SRBMiner-CN-n.exe where n is the instance number

--run filename [name of .bat file to run]
Name of .bat you want to run if SRBMiner process in not running


Note:
Miner is considered 'not running' after 2 checks!

Examples:

1.
SRB-Restarter.exe
[This will set interval to 10 seconds, and start.bat if SRBMiner process is not running. It will monitor for a process named SRBMiner-CN.exe]

2.
SRB-Restarter.exe --interval 5 --run turtle-coin.bat
[This will set interval to 5 seconds and run turtle-coin.bat if SRBMiner process is not running. It will monitor for a process named SRBMiner-CN.exe]

3.
SRB-Restarter.exe --interval 30 --run start-heavy.bat --instance 1
[This will set interval to 30 seconds and run start-heavy.bat if SRBMiner process is not running. It will monitor for a process named SRBMiner-CN-1.exe]


If you copy the whole folder from the .zip into SRBMiner folder, you have an example SRB-Restart.bat inside that will check for the SRBMiner-CN.exe process every 5 seconds, and run start.bat that is in the main miner folder (that's why the '..\start.bat', it means one level back).

IMO, temps are a big problem for vegas.  If you don't maintain the HBM2 temps BELOW 70 C, you will lose hashrate.  I didn't not notice a huge increase in temps when swapping 56 BIOS with 64.  Greater range for clocks and memory frequency increases temps proportionally.  Before messing with swapping BIOS, I'd solve your temp problem first.  In other words, why increase the clocks and frequency capability when it is simply going to throttle back?

Totally agree; I've found success with keeping core volts below 950, memory to 800, fans set to 3200 min with a 4900 max, and set target temperature to 66 (you can even try lower if you don't mind the loud noise of the fans).

I've also had cases where the cards run much hotter for no apparent reason and my only guess its a radeon software or driver issue whereby it's ignoring my minimum core volts, driving more volts through the card and making them hotter.  A reboot and disable/enable in device manager for each card has fixed this, and then they run 10c cooler until it mysteriously happens again.

I'm on a mixed rig of nvidia and amd, and often wonder if that's not causing me some weird issues.

Cheers
