Cast XMR Version 1.5.0 (2018/9/27)

  • Support for the Monero V8 Network Upgrade which introduces a new CryptoNight variant CryptoNightV8 aka CNv2. The Monero V8 update is scheduled for 18th October. In case you are mining Monero make sure to update Cast XMR before that date. Also make sure that the algo for Monero is not explicitly set to CryptoNightV7 but set to auto detect with --algo=-1 to automatically switch from CryptoNightV7 to CryptoNightV8 when the upgrade is happening. Please also note that the CryptoNight V8 algo has added complexity which decreases the hashrate up to 7% for Vega GPUs.

Cast XMR Version 1.4.0 (2018/8/27)

  • Support for BitTube (TUBE) V4 Pow Update which introduces the new algo CryptoNightTUBE-Heavy aka CN Saber. Use --algo=5 to mine CryptoNightTUBE-Heavy

  • Support for CryptoNight-Fast introduced with the Masari (MSR) update. Set --algo=8 to mine Masari (MSR).

  • Support for Festival Coin (FEST) upcomming update which introduces a new CryptoNight variant: CryptoNightFEST. Use --algo=9 to continue mining Festival Coin after the network update happend

  • Tested with Radeon Adrenalin Driver 18.5.1

  • Performance improvement for job switches with multiple GPUs

Cast XMR Version 1.2.0 (2018/6/12)

  • Support for the Haven (XHV) V3 update. In case you are mining Haven set --algo=7
  • Support for Stellite (XTL) V4 Update. Set --algo=6 in case you are mining Stellite
  • All new --intensity option to specify the memory allocation in the range of 0 to 10 (up to 12 for Vega Frontier Edition). The default setting will correspond with the settings of version 1.0 and are displayed at startup.
  • Vega Frontier 'Large Pages' support added, upto 30% higher hash rates for CryptoNight-Heavy, 5% increase for CryptoNight
  • Includes the switch-radeon-gpu command line tool to restart GPUs, switch on/off HBCC, Compute Mode and Large Pages
  • Nicehash supports now up to 24 GPUs (previous version was limited to 8)
  • --maxmem option is deprecated, will now be mapped to an corresponding intensity setting
  • --forcecompute is deprecated, 'Compute Mode' of Polaris GPUs will be automatically detected. To overwrite use the --intensity option
  • Default mining algo changed to CryptoNightV7, to still mine CryptoNight Classic add --algo=0
  • Tested with Radeon Adrenalin Driver 18.4.1
  • Fix for "unauthenticated shares" pool error

  • Support for Aeon (AEON) CryptoNight Lite variant set --algo=3 to mine
  • Support for Turtlecoin (TRTL) CryptoNightV7 Lite variant set --algo=4 to mine
  • Support for BitTube (TUBE) (forme IPBC) CryptoNight Lite IPBC variation set --algo=5 to mine
  • Up to 3% performance improvement with new option --maxmem to allocate the maximum memory of the card. For Vega cards the "HBCC Memory Segment" has to be disabled in the Radeon Settings to use the option.
    Disadvantage is a higher risk of hash rate drops when the --maxmem option is used.

  • support for CryptoNightV7 set --algo=1 to mine:
  • support for CryptoNight Heavy set --algo=2 to mine:
  • CryptoNight-Heavy fix for very low hash rates when HBCC Memory Segment is enabled
  • HBCC Memory Segment performance hint for Vega64 when mining CryptoNightV7
  • Improvement for 4GB versions of RX 470/480/570/580 when mining CryptoNight
  • Improvements for RX Vegas that achieve 99% the performance of the Blockchain Compute Beta driver with the latest standard Radeon Driver 18.3.4
  • --ratewatchdog experimental option to monitor the hash rate, in case an occasional happening drop of the hash rate is detected the kernel will be resetted to restore the optimal hash rate

  • support for the Monero V7 network upgrade. Read more about it here
  • the Monero PoW switch will be automatically detected, no restart of cast XMR is required. Only make sure to update cast XMR before the network upgrade is happening and that the used Monero pool supports the network upgrade
  • no decrase in hash rate for other currencies was introduced by the change
  • CryptoNightV7 will run at the same hash rate as CryptoNight
  • for any case there is the new -algo option to force which CryptoNight variant to use:
    • -1 = autodetect (default)
    • 0 = CryptoNight
    • 1 = CryptoNightV7 (Monero V7 network upgrade)

  • 1% performance gain for Vega Frontier Edition with Blockchain driver (fastest GPU around)
  • 1% performance improvement with current stock driver (18.1.1) for RX Vega 56/64 (40% to go to reach Blockchain driver)
  • fix for random blocking console output
  • GPU now always logs with its device id not the order they are listed in the -G argument
  • --log option to log output to a file
  • remote access includes CORS support in HTTP header

  • Fix for OpenCL automatic platform detection for Crimson driver 17.12.1 (Adrenalin). Blockchain driver is still way more performant on Vegas though
  • kernel optimizations result in subtle performance improvements
  • --fastjobswitch option (experimental) to force fast switching to new jobs. When enabled the GPUs will switch to the new job within less then 100ms. This improves the effective hash rate by 1 to 5% as nearly no GPU performance will be wasted on calculating outdated shares anymore. The drawback is a slightly lower displayed hashrate as while switching no hashes are calculated.
  • improved support for more then 8 GPUs
  • support for Radeon RX 470/RX 570 (Polaris) added
  • --forcecompute option to force kernel for compute mode on Polaris (RX470/570/480/580) GPUs. In the Radeon Settings GPU Workload has to be switched to 'Compute'. This option is available in Crimson 17.10.2 (or later) driver and reaches nearly the same performance on Polaris based GPUs as with the Blockchain driver.
  • openCL platform is auto detected if --opencl is not specified
  • --nonicehash option to disable nicehash support
  • nicehash support will automatically disabled if more then 8 GPUs are used. Otherwise search space could be exhausted to early and the GPUs search in overlapping nonce ranges.
