Using XMRig for Mining RandomX, RandomWOW and RandomXL on CPU

28, Sep 2019

If you are looking for a CPU miner with support for the RandomX mining algorithm that Monero (XMR) will be forking to you might want to try the latest XMRig miner. Apart from the RandomX algorithm it also supports two variations, namely the RandomWOW used by Wownero and RandomXL used by Loki, so that you can get actual performance on what hashrate to expect from your CPUs. If you need a pool where you can test the new RandomX algorithm you try the randomx-benchmark.xmrig.com:7777. We remind you that currently AMD’s latest Ryzen CPUs do manage to offer the best performance in terms of hashrate. Also CPU performance of a higher-end processor for RandomX currently better than what you will most likely get from a single or even multiple GPU mining rig for the moment…

XMRig Algorithm names to use:
– rx/0 for RandomX (Monero)
– rx/wow for RandomWOW (Wownero)
– rx/loki for RandomXL (Loki)

Monero (XMR) to Hardfork to the RandomX Algorithm on November 30th

27, Sep 2019

Monero (XMR) will be once more changing its PoW algorithm for mining in an effort to attract regular miners CPU/GPU miners and drive away FPGA/ASIC miners. Testing on the private RandomX testnet has concluded successfully and RandomX PoW mining will move to public testing on the XMR testnet later today. There is quite some time left before the fork happens though, it is scheduled for block 1978433 that should hit sometime on November 30th, so there is time for you to get familiar with the new RandomX algorithm by then. If you are interested in checking out the performance of your CPUs, then you might want to check the official RandomX Benchmark app (link for download below). There is also a not so optimized OpenCL miner available that works on both AMD and Nvidia GPUs available as well, though performance might be disappointing compared to that of higher-end CPUs at this point.

It is interesting to note that the RandomX algorithm apparently favors CPU mining due to its design even GPUs might not do so well initially with it, though we are probably going to see better optimized GPUs miners soon enough. All in all this might make CPU mining attractive to miners around the fork date, though there are other factors to take into account as well, so we will have to wait and see. AMD’s Ryzen CPUs are doing particularly good in the initial benchmarks of the RandomX algorithm as it is already being used by the new project Epic Cash (EPIC). You can see that the AMD Ryzen 9 3900X is doing particularly good in terms of performance with its big number of cores and low power consumption, though it is also an expensive and still hard to find product.

New T-Rex 0.14.4 Nvidia Miner With Support for the X16Rv2 Algorithm

26, Sep 2019

The latest T-Rex Nvidia GPU miner version 0.14.4 has also introduced support for the new X16Rv2 algorithm, just like the z-enemy 2.2 miner did (the algo that Ravencoin is forking to starting next month). Although the z-enemy miner was technically first with an official release, there was unofficial beta of t-rex 0.14.2 made available by the PEXA project a few days earlier with X16Rv2 support. Do note that you can already test X16Rv2 mining with PEXA Coin on mainnet and not only on pools that have implemented RVN testnet mining with the new X16Rv2 algorightm.

Performance wise it does seem that the T-Rex 0.14.4 miner offers similar or slightly faster hashrate compared to Z-Enemy 2.2 in most algorithm combinations on GTX 1080 Ti after a quick test, though it is best that you compare on your own mining hardware. Also T-Rex has implemented a new command line parameter that enables the miner to automatically switch to a new algorithm at user set fork time (example for RVN: --fork-at x16rv2=2019-10-01T16:00:00). Do note that the T-Rex is a closed source miner software with 1% development fee built-in. Also make sure you have a recent video driver installed (the latest for CUDA 10+ support) as the binaries for both Linux and Windows are available in versions compiled for CUDA 9.1/9.2/10.0.
