T-Rex 0.26.8 ETHW, ETC (+dual mining) GPU miner

[trexminer]

Hi

Worked like a charm so far 

- Somehow every instance of Trex is suddenly using 11-12% CPU of Ryzen 5. I had to do a Bios reset. Before it was like below 1% CPU usage per instance.
I also changed some system settings because recently I added from stock a GTX 970 would not work in Trex for Ergo, ETC.

 "Can't find nonce with device. Cuda exception. Cuda error not supported."

 It works fine in miniZ miner.

Any Idea about sudden high CPU Usage?
Maxwell still supported? I read it should be.

Best regards

Maxwell is still supported.

T-Rex 0.24.6

* ("ethash") Improve LHR unlocker, LHR tune value increased from 71 to 74 by default.
   The new LHR tune scale is somewhat different, so it's recommended to let autotune find the optimal parameters
   (in other words, for the first run, remove "--lhr-autotune-mode" and "--lhr-tune" parameters from your bat file if they are set)
* ("ethash", "autolykos2") New "--lhr-autotune-step-size" and "--lhr-autotune-interval" parameters for finer control of LHR unlock behaviour
* ("ethash", "firopow") Add ETH+FIRO dual mining (use the same OC settings as ETH+RVN)
* ("autolykos2") New "--dataset-mode" parameter to enable/disable double buffer mode: 1 - single buffer mode, 2 - double buffer mode (default)
* Add SOCKS5 proxy support (see "--proxy" parameter)
* New "--temperature-color-mem" parameter to control memory temperature highlighting in console and WebUI
* (WebUI) Multiple improvements:
   - 24H view on the graph
   - Ability to hide individual charts (power, avg hashrate etc.) on the graph
   - Recompute average hashrate/power when zooming in the graph
   - Ability to reorder/hide GPU table columns
   - Auto-propagation of the miner node list to all nodes

Bug fixes:
* ("ethash") RTX 3060 GA104 is not recognised as an LHR card
* Veriblock mining is broken since 0.24.2
* (Linux) Log file contains ANSI escape sequences
* (WebUI) Log file retrieved through WebUI has trailing zeros

not bad, on the video card Palit 3080 TI hashrate is about 82-83 with lhr 73

would anyone give the result
hashrate given by a regular 3080 video card with lhr?

I keep getting an error with ethash algo.

How to dualmine ETH+ FIRO? I tried using the bat file inside the miner, but FIRO mining was 0 mh/s and ETH speed was like is was always. I have no LHR cards?

If you want to dual mine with a non-LHR card you need to manually specify "--lhr-tune 30" (or whatever ETH percentage you like) in your bat file.

GTX 3080 Ti can give 92+. Try GPU lock (1560) and mem around 10800-11000.

Any chance to add zelcah (flux) ?
I love T-Rex but, want to start mining flux, and at this time only Gminer or zmini can mine flux.

For those without a LHR card would there be any benefit to this beyond spreading out risk between coins?
Also +1 on Flux

T-Rex 0.24.7

Bug fixes:
* Some command line arguments don't take precedence over the values set in a config file (e.g. "--lhr-autotune-step-size")
* (WebUI) Performance degradation introduced in 0.24.6
* (WebUI) Monitoring page shows a blank page if you had 15M or 2H graph views selected on while using an older version of T-Rex
* (WebUI) Impossible to set LHR tune values with decimal point

HiveOS users: many of you complained that your hashrate on LHR cards is fluctuating too much compared to the Windows version. The reason is HiveOS sets "hashrate-avr": 30 for T-Rex causing it to report 30-seconds average hashrate as opposed to 1-minute average (default).
A temporary solution would be to edit your flight sheet and manually add "hashrate-avr": 60 to the "Extra config arguments" field. Otherwise, we've been told there will be a HiveOS release that fixes it permanently.

Friends, I have the following problem, it doesn't show clocks and power consumption, any tips?

I don’t know where you saw such results, the 3080 ti video card cannot take the core frequency of the locked state in any way, the lhr mechanism will block the video card if it takes more frequency than the set limit value for bypassing lhr and therefore it is impossible to fix the core at a certain high value, which is what I have happens, in fact, therefore, the speed is 82-83mh otherwise it could be higher

Hi! With versions 0.24.5-0.24.7 I have a problem with dual mining ETH+ERG on 3060ti. I've tried to set --dataset-mode=1, run without any overclock but without success. On version 0.24.2 everything works fine.

Apparently the LHR mechanism is individual and depends on the consumption of the video card, on my video card on the same drivers I can achieve somewhere 85-86 megahashes, while increasing the memory frequency over 850 MHz is not effective, the speed does not increase, and the LHR limit is reduced, as well as any locks with the parameters lock-cclock, lock-cv only reduce the speed, the optimal value is 0
I think this is due to the fact that with an increase in the clock frequency of the memory, the total consumption of the card increases and ultimately it exceeds a certain limit set for the LHR to operate

show your core frequency, the real one, which is displayed in hwinfo, for example, since on my 3080 TI cards it cannot be blocked and it constantly jumps up and down
I do not deny that such a result is possible, but my video card gives out otherwise

If you experience high CPU usage by T-Rex miner process on Windows and your NVIDIA drivers are 471.11 or newer, the most likely cause is the "Hardware-accelerated GPU Scheduling" feature.

To disable it, go to Start -> Settings -> Display -> Graphics settings, and turn it off.
