One Day Left Until Monero (XMR) Hardfork to RandomX

29, Nov 2019

Monero (XMR) will be hardforking tomorrow, November 30th, at block number 1978433. The fork will change the current CryptoNight R algorithm for mining to the new Random X PoW algorithm, essentially moving the mining of the coin to CPU. There are already a few RandomX miners out there that you can use, links below, and although some f them also support AMD or Nvidia GPUs, you would probably want to stick to CPU mining with RandomX as the algorithm is optimized for processors and GPU mining performance is far to low currently to be considered. Also as already noted AMD’s Ryzen 3000 series of processors is doing great for Random X and performance wise it is much better than recent Intel alternatives.

Another important thing to note regarding the upcoming for is if you are mining directly to an exchange using a paymentID. Since after the fork support for PaymentIDs will be discontinued, in order to continue successfully mining after the network update you need to also update your mining address. Alternatively you can just update to the latest v0.15.0.1 wallet and use a local wallet address for mining after the fork. For an up to date pools for mining XMR you can check the list at MiningPoolStats, they should all be ready for the fork by now.

Mining software with RandomX support:
– XMRig 5.0.0
– SRBMiner-MULTI 0.1.7
– XMR-STAK-RX 1.0.0

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.

New NBMiner 26.1 With Improved Nvidia Performance for CKB and Dual Mining on AMD

15, Nov 2019

The latest NBMiner 26.1 update comes with a bit of improvement in the performance for mining CKB on Nvidia GPUs as well as support for Dual Mining ETH + CKB on AMD GPUs (dual mining was already available for Nvidia users). This update is just in time for the official launch for the Nervos CKB mainnet launch planned for tomorrow that uses the Eaglesong mining algorithm. Aside from NBMiner, you can also use GMiner and SRBMiner-MULTI for the Eaglesong algorithm, though with the latest update NBMiner should be slightly faster on Nvidia than GMiner.

We remind you that the NBMiner is a closed source GPU miner for Nvidia CUDA and now AMD as well that is available for both Windows and Linux operating systems and it has the following developer fee built-in: tensority_ethash 3%, tensority (Pascal) 2%, tensority (Turing) 3%, ethash 0.65%, cuckaroo & cuckatoo & cuckaroo_swap 2%, progpow_sero 2%, sipc 2%, bfc 3%.
