T-Rex 0.19.9

* Add ability to execute custom scripts upon certain events with new parameters:
"--script-start"
"--script-epoch-change"
"--script-crash"
"--script-low-hash"
* ("ethash", "kawpow", "octopus") Add "--dag-build-mode" parameter to fine tune DAG build mode (mostly to help with various stability issues, see readme for details)
* Allow non-existent GPU indices passed in to "--devices" / "-d" parameter: the miner will display a warning message but will continue mining using the GPUs it could find)
* Cosmetic changes: improve error descriptions, display block number when mining solo at some pools (2miners)

Bug fixes:
* ("ethash", "kawpow", "octopus") Stability regression for Pascal GPUs
* Mining pool difficulty is not always updated in the summary report (https://github.com/trexminer/T-Rex/issues/131)

**NOTE**: if you experience stability issues when mining "ethash" right at the start or upon epoch change, e.g. some GPUs fail start with "GPU is idle" or "NVML: can't get GPU#" errors, try running with "--gpu-init-mode 1", it will force sequential GPU initialisation and reduce the load on your hardware (set to 2, 3, etc to indicate how many cards may be generating DAG in parallel)

Maybe a noob question but how do you add "--gpu-init-mode 1" into a config.json? doing this on Hive OS and they seem to use a config file instead. Would it be "gpu-init-mode" : "1" ?

Wow, I'm going to test it later... Thank you man, it's really nice to see a miner dev who's listening to miners and doing fast updates!
No worries. Let me know if it works for you, the functionality is a bit experimental at this stage, no one has used it, so no feedback yet Smiley

So if I understood this correctly, for exampe if I want to initiate reboot.bat for restarting the rig at epoch change the command should look like this:

--script-epoch-change reboot.bat

Or should I write the full path like this:

--script-epoch-change D:\t-rex\reboot.bat

Because in readme file you wrote this:
(eg: --script-start path_to_user_script)

So, is it really a path or just a name of the script in the t-rex miner folder?

Both should work. You can try "--script-start" parameter with your script first, that will catch all potential issues early, while you're at your rig. And if everything works as expected then set "--script-epoch-change" Smiley

When I start it like this it's "working"

--script-epoch-change reboot.bat

I mean, it says this:
http://www.imagebam.com/image/ae8d421367373751

So it should work, right? But it's not doing anything, just starts mining

In simple reboot.bat file I have this command:
shutdown /r /t 5 /f

And it was working before with phoenix miner...
Any suggestions? Smiley

So for a 6x 3070 rig it would be --gpu-init-mode 6    or  --gpu-init-mode 1,2,3,4,5,6  ? 

Awesome job on a quick update btw.

It should work but doesn't Smiley There's an issue, we'll fix it in the next version.

Problem when mining octopus for the last 2 day, before your miner are the best one with realy nice speed... Plz fix ASAP

i try 2 different pool, same problem

Please try 0.19.7 and let me know if it fixes the issue https://github.com/trexminer/T-Rex/releases/tag/0.19.7

Hello!
Dear developers.
Please help me set up monitoring rig.
In the config, hiveos wrote these lines.
"--api-bind-telnet": "192.168.1.162:4068"
"--api-bind-http": "192.168.1.162:4067"
In the browser, I can not monitor the rig either through 4068 port or through 4067.
What am I doing wrong? Is there some kind of monitoring software?

Hi. Monitoring web page is accessible through a URL printed by the miner when it starts up, for example:
"For control navigate to: http://192.168.88.235:4067/trex"
However, since you're already using HiveOS I see no point in using it, HiveOS monitoring features are far superior.

I kind of have the same question. I don't know what dictates which version of Cuda to download. If you have say a GTX 1070 will any Cuda versions work or is there a particular one you need to download and run, and if so why that particular one?

Any ideas why mem tweak (--mt #) doesn't seem to have any effect on my 1070 rig? Windows 10, t-rex 19.9, ethash...

BTW, it's working great on my 1070 TI rigs, so thanks.

CUDA 11.1 version is the only one that works with 30xx GPUs

Hello,

i run 4 different 3080 on a Z68 Extreme 3 Gen 3.

Whenever i try to run all 4 together one card randomly idles.

At the end it goes like this

Sometimes is get this at the "initialisation" after retry

Does anyone knows how to fix it?
