The latest version 1.8.4 of the CryptoNight AMD GPU miner SRBMiner brings significant performance boost for all of AMD’s HBM memory based GPUs, namely the Radeon Vega56, Vega 64, Vega FE and the latest Radeon VII with HBM2 video memory. The performance boost for these video cards can be up to about 15%, so definitely worth upgrading any mining rigs with the newly released miner for the extra hashrate you will be getting… and that apparently goes for all of the supported algorithms! To take advantage of the extra performance boost you need to play around with the new parameter tweak_profile checking the level of tweak profile that your GPUs can handle and applying it. Apparently the improvement is based on memory timings modification thanks to the work of Eliovp and his useful AMD Memory Tweak Tool.

You can find the full changelog for the latest release quoted below. Do note that the developer fee is ~0.85% for both normal mode and algorithm switching mode as SRBMiner is a closed source miner available for AMD GPU miners only under Windows.

SRBMiner V1.8.4 Full Cangelog:
– Performance increase for Vega56/64/Fe/Vii up to 15%!
– Minimum for ‘main_pool_reconnect’ is now 60 seconds instead of 180
– Added new cmd parameters: –disabletweaking, –cgputweakprofile
– Added new config parameter: tweak_profile
– Minor bug fixes

The latest update of the AMD GPU miner lolMiner 0.8 brings support for the Cuckatoo 31 algorithm used by Grin, for GPUs with either 4GB and 8GB video memory (lower memory mens less performance) for Windows and Linux. To mine with the new algorithm you need to use the parameter --coin GRIN-AT31, NiceHash does not currently seem to be supported for C31 though. It is interesting to note that the Grin cycle finding is completely done on the GPU, so the miner has almost zero CPU load (on AMD, Nvidia has some due to OpenCL back end). Aside from Cuckatoo 31 support the new version also has some Stratum bug fixes (NiceHash) for Equihash 144/5, 192/7 and 96/5, improved general stability of the miner as well as added distinct 1GB, 3GB and 4GB as well as 6GB and 8GB kernel for mining MNX for Windows (the Linux version that already implemented had this in 0.7.1).

We remind you that lolMiner is a closed source OpenCL GPU miner available for Windows and Linux as pre-compiled binaries only and that there is a developer fee for using the software (1% for all supported algorithms). It might work on Nvidia with OpenCL, however stability and performance might not be optimal, so it is best for use with AMD GPUs.

The very useful AMD Memory Tweak Tool that was initially only available for Linux is now also available as a beta for Windows users as well. With the help of the free and open source software from Evilop you can read and modify memory timings “on the fly” for compatible AMD GPUs that do come with GDDR5 or HBM2 memory (HBM was also supported initially, but is temporary disabled as it apparently need some fixing). Before starting to do anything with the tool you should check the Readme and run AMD Memory Tweak with the option --current in order to see what GPUs it detects and what memory settings are currently active. It might also help to see what other users have found out as good working configurations for their hardware and have reported on Bitcointalk based on their experiments with the memory tool.
