T-Rex 0.26.8

* Add support for NVIDIA 40xx GPUs
* Handle v520+ LHR-free video drivers correctly

Please upload the full log file, I'll have a look. Thanks.

That's only for LHR cards. See https://github.com/trexminer/T-Rex/wiki/Dual-mining#behaviour-and-tuning for details.

T-Rex 0.25.9

* Allow setting "LHR dual ratio" parameter for ETH+ALPH dual mining,
  e.g. "--dual-algo-mode a12:r10:lr12" (dual ratio 10, LHR dual ratio 12)
* (Linux) Display memory temperature for GPUs with GDDR6X memory type (requires administrative privileges)

Bug fixes:
* ("progpow") Miner frequently disconnects from the pool when mining SERO

T-Rex 0.25.8
* Improve ETH+ALPH dual mining performance for LHR cards (high power limit / core clock is important to get high ALPH hashrate)
* "--lhr-algo" parameter is deprecated and is now an alias for "--dual-algo"

Bug fixes:
* Miner uses incorrect worker name for the secondary algorithm if "--worker2" is set
* (WebUI) Various fixes around dual mining configuration setup

T-Rex 0.25.6

* Add ETH+ALPH dual mining support for non-LHR cards (see https://github.com/trexminer/T-Rex/wiki/Dual-mining for more details)
* (WebUI) Add an optional "Lock Count" column to track the number of times the GPU hit an LHR lock

Bug fixes:
* (WebUI) Login sessions are preserved between miner restarts if the watchdog is enabled

T-Rex 0.25.2

* Add blake3 algorithm (Alephium coin)
* Add ETH+ALPH dual mining mode for LHR cards (ETH 68% / ALPH 32% by default)

NOTE: solo mining to Alephium nodes isn't supported

T-Rex 0.24.8

* Add DNS-over-HTTPS support when resolving mining pool domain names (see "--dns-https-server" for details)
* Add an option not to set mining pool domain name in SNI header for SSL connections (see "--no-sni")
* Resolve domain names through SOCKS5 proxy if "--proxy" is set
* Display mining pool IP address in console
* (WebUI) Make the monitoring page layout more compact on mobile phones

Bug fixes:
* Miner is not creating a log file when "--log-path" is specified
* GPU does not get turned off when overheated while mining in dual mode
* (WebUI) Graph zooming is not scaling the charts correctly

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.

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.

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

https://github.com/trexminer/T-Rex/wiki/FAQ#high-cpu-usage

Maxwell is still supported.

Yes, but not in the near future, sorry.

T-Rex 0.24.4

* ("autolykos2") Increase pool-side hashrate by 1-4%.
  The miner now generates the dataset for the next ERGO block before it arrives with a small penalty to reported hashrate, and when the next block does arrive, it immediately starts hashing without losing 1-4 seconds on creating the dataset.
  Memory requirements are doubled in this mode as the GPU has to hold two memory buffers. If there is not enough memory on the GPU for two datasets, the miner will fall back to running in single buffer mode.
  To take the full advantage of this mode it's recommended not to set power limit but instead limit power consumption with "--lock-cclock" - this will allow the miner to draw more power during dataset rebuild and not lose hashrate. If you prefer to keep your power consumption constant, you can still set the power limit, however, in that case you'll notice a slight hashrate drop after each block.
  **Please note** that in both cases the miner should give you higher pool-side hashrate in the long run compared to previous versions. Miner's reported hashrate now fully accounts for dataset creation time.
* ("kawpow", "firopow") Report hashrate to the mining pool
* (WebUI) Add support for displaying multiple rigs (nodes) on the same page; various improvements and fixes
* Add "--devices-info" parameter to list available CUDA devices

Bug fixes:
* ("ethash", "autolykos2") LHR lock detection is triggered by short-term hashrate drops, e.g. when turning on the monitor connected to the GPU.
* Original overclock settings are not restored upon miner shutdown in dual mining mode (only applicable if you overclock GPUs with t-rex)
* (WebUI) Cannot set "--gpu-report-interval" to "0" (disable)
* (WebUI, API) GPUs are sometimes paused with a considerable delay (should be immediate)

I think 4gb cards should be able to mine ERGO and RavencoinLite (0.19.14 version only), but I have no idea what the hashrate is going to be.

It is not possible

"no-new-block-info": true

Possible reasons include running the miner with --extra-dag-epoch parameter set, or something else is running in the background
