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

[doktor83]

Dok, could you remove the 120 minutes cap of --maxnosharesent for next release?

Thank you

I will make that parameter optional, so if it's not used there won't be any default value. Also will set the max to 24h.
This parameter can get 'crazy' when windows re-adjusts time if ntp is used, so it's better if its not on by default.

Hi, Doc!
I have a few questions that I would like to clarify:
1. If I use config file, where I specify gpu-only parameters (intensity, threads, worksize), then parameters rebootscriptgpuwatchdog and rebootscriptminrigspeed, which specified via cmd, not working. But if these parameters specify in config file, they are working. So, is it possible to give priority to cmd input over config file?
2. Is it possible to add support for variables for pools file? If you have many rigs you must specify worker name, in pools.txt, on each of them, and it's not comfortable. But worker name can be taken from variable %computername%.

1. You set everything either in config, or cmd. There is no more mixing of these two since 1.8.0 . So you can set --rebootscriptgpuwatchdog and --rebootscriptminrigspeed

2. Sorry but no. It would take too much time, and i don't think it's such a valuable option.

Code:

SRBMiner-CN.exe --setcomputemode

(sets AMD gpu's to compute mode & disables crossfire - run as admin)

Thanks, tried. Same sh!t, 1100Hs

Hi Dok
   Great Program runs perfectly, got a question, how do you change the --maxnosharesent ? ive tried setting it for 10minutes. i tried -> ( --maxnosharesent 600 ) and then -> ( --maxnosharesent 10) tested both but it did not reset on either setting. ( not a big issue just wanted to know if i was setting it wrong.)

 I also have a request, could you add 1 or even 2 decimal places to avg share time ( 1.xx secs ) to provide more accuracy on hashrate submission for static diff. i would greatly appreciate it.

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.

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

[duketasos]

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.

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.
