    • teamredminer-v0.7.19 (Ethash solo-miner share high-score list added, use --high_score to enable. Ethash single buffer dag for a small power save. Only available on recent drivers and should in theory always be an improvement. It is not verified 100% stable yet and therefore not the default in this version. Enable with --eth_dag_buf=A to test. Miner gpu initialization procedure rewritten. The init procedure should now hopefully be much more stable, especially on Navis in general and even more so for 5600(XT)s. Added adjustable ratio support for quota and load_balance pool strategies (see --pool_ratio). Rewrote miner init procedure to be more stable in general. Fixed issue where output blocking could cause mining work to stop. Reduced main binary size. Reintroduced single DAG buffer support for recent drivers allowing large single allocations (see --eth_dag_buf). Ethash added high score list of the 15 highest value shares found since start (see --high_score). Ethash small improvements in keeping the gpu busy over epoch switches.

    • teamredminer-v0.7.18 (Added etchash support (algo etchash and --eth_variant_mode). Added dag cache support, mostly intended for eth+zil mining (--eth_dag_cache). Changed the default for ethash ramp-up and staggering to false (--eth_ramp_up and --eth_stagger). Integrated with SimpleMining watchdog by using option --watchdog_script)
  • 2020.11.24
  • Miners update

    • lolminer-v1.16a (Added support Ethash and Beam Hash III for RX 6000 generation of GPUs. All supported algorithms now show the share difficulty and have best share statistics. Added --rebuild-defect n to trigger a rebuild of DAG if a GPU produced n defect shares on the current one. Default is 3, use 0 to deactivate this feature. Added --workmulti n to modify the amount of Ethash work a GPU does per batch. Higher values will cause less CPU load but more stale shares, lower values will give less stale shares but higher CPU load. Performance may vary for different values. Default is 128. New: if Ethash pool disconnects within 2 seconds from connection attempt (immediate reconnect), then the other stratum mode is tested to login. New: AMD Vega and newer cards now display memory temperature in statistics (only visible if there is at least one such GPU in the rig). Default ethstratum changed from ETHV1 to ETHPROXY for better pool compatibility. Stratum pool addresses now understand "stratum+tcp://", "stratum+ssl://" and "ssl://" prefixes (turning on or of ssl / tls automatically) for better compatibility with existing configurations. Slightly reduced CPU load when mining Ethash. New coloring scheme with more friendly colors. For terminals that do not have rgb colors (e.g. shellinabox) use --basecolor to restrict to a simpler set. Use --nocolor to deactivate coloring completely. Fixed: Cards may crash when switching from ZIL cache back to normal mining. Fixed: Wavy hashrate - especially for rigs with many AMD Navi GPUs. Fixed: Watchdog not called when a GPU is stuck & extremely high CPU load on crashed GPU. Fixed: Hashrate reporting not working on some pools (e.g. sparkpool). Fixed: Miner can crash after trying to reconnect to same pool over 5 minutes. Fixed: Miner crashes when mixing TLS and non-TLS pools for fail-over)
    • xmrig-v6.6.0 (Online benchmark protocol upgraded to v2, validation not compatible with previous versions. Single thread benchmark now is cheat-resistant, not possible speedup it with multiple threads. RandomX dataset is now always initialized with static seed, to prevent time cheat by report slow dataset initialization. Zero delay online submission, to make time validation much more precise and strict. DNS cache for online benchmark to prevent unexpected delays)
  • 2020.11.23
