XMR-STAK-RX 1.0.0 Is a New Totally Free RandomX CPU Miner

16, Nov 2019

The developer of the XMR-Stak miner has released XMR-STAK-RX 1.0.0, a new miner supporting only the RandomX algorithm and its variants for CPU miners and with no development fee built in. The miner is available for both Linux and Windows as pre-compiled binaries. This is definitely good news for anyone interested in the nearing Monero (XMR) hardfork to RandomX at the end of he month or any of the other altcoins that have switched to RandomX variants or are planning to do so after XMR forks.

Now there is one more option for miners to choose from regarding RandomX support, besides XMR-STAK-RX there is the first one with RandomX support XMRig as well as the more recent also new miner SRBMiner-Multi. Just like XMRig does come with GPU support for RandomX, XMR-Stak also supports GPU mining, however considering that RandomX is optimized for CPUs that is not much of advantage as even high-end video cards perform similar to the low-end processors with much higher power usage, making GPU mining RandomX pretty pointless for the moment.

Do note for the moment that XMR-STAK-RX 1.0.0 supports only RandomX, RandomX Loki and RandomX WOW, no support for the Random ARQ algorithm used by ArQmA (ARQ), so you have to sue any of the other two miners for that one. Performance wise XMR-STAK-RX 1.0.0 does seem to be about 1000 H/s slower compared to the other two alternatives at the moment running on AMD Ryzen 3600 CPU (on RandomX and RandomX Loki, RandomX WoW is better), so there is more to be desired in terms of updates regarding hashrate. Regarding performance on Intel CPUs, our test on an Intel Core i7 6850K has shown pretty much the same low performance with XMR-STAK-RX as with the other miners, so apparently AMD support might need some more optimizations for best performance.

YadaCoin is Yet Another Project That has Forked to RandomX

14, Nov 2019

It seems that another crypto project has moved to RandomX as a Proof of Work mining algorithm – YadaCoin. Yada is a blockchain social media protocol that uses YadaCoins for social interactions, and even though the project started in 2018 it seems to be slow in getting a lot of attention. We just recently discovered it thanks to the RandomX fork they had a few days ago and while we wanted to give it a try and mine some coins, unfortunately our efforts ended up in vain. We could not make the official Windows mining software to work (no pools yet, only solo mining), have not tried mining under Linux, though unfortunately there is not much information available to help… not even on the fork itself. It seems that unless you have been following the development from the start you might have trouble getting to understand how to make things work and that is never a good thing for a crypto project that wants to become mainstream, let alone one that wants to build a social media blockchain.

– If you like digging and trying things out, then you might give YadaCoin with RandomX mining a go…

New SRBMiner-MULTI CPU and AMD GPU Miner 0.1.6 Beta With Improved Performance

12, Nov 2019

The latest SRBMiner-MULTI CPU and AMD GPU Miner version 0.1.6 brings some improvement in CPU mining performance thanks to better utilization of processor threads, though it seems that further optimizations might be needed. In a quick test with RandomX-based algorithms we are seeing an improvement in hashrate compared to the previous SRBMiner-MULTI 0.1.5 that has introduced RandomX support, but full thread utilization may still not at 100% for all processors and performance is a bit lower when compared with XMRig on the same mining hardware, still it is good to see that efforts are being made for further improvements.

SRBMiner-MULTI CPU & AMD GPU Miner 0.1.6 beta changelog:
– Fixed threads binding on systems with more than 1 numa node
– Better auto configuration for cpu mining
– Previous two fixes should bring higher hashrates
– Added pool controlled algorithm switching capability (Monero Ocean)
– Added pool config parameter “algo_min_time” and --algo-min-time to cli (Monero Ocean)
– Added pool config parameter “keepalive” and --keepalive to cli

Update: There has been an update that fixes issues for SRBMiner-MULTI 0.1.6 that corrects the less than 100% load on all cores/threads of the processor, so now the performance is even better and should be pretty much the same as what XMRig currently offers on the same mining hardware as far as RandomX and its variants are concerned, so just redownload version 0.1.6 if you downloaded the initial release.
