Optimizing Nvidia GPUs for Lower Power Usage for Radiant (RXD) Mining

Radiant (RXD) is another project that is quickly catching up with crypto miners, so we are going to be sharing some tips on how you can optimize Nvidia GPUs for better performance with lower power usage for mining RXD with the Bzminer software. Radiant uses the SHA512256d algorithm, another GPU-intensive algorithm, so you can go as low as possible with the video memory and higher on the GPU clock to get better performance with lower power usage for this one. AMD GPU miners interested in mining Radiant (RXD) should go for the SRBMiner-MULTI CPU & AMD GPU Miner 1.1.3 software, however it does not come with so advanced GPU clocking features, so you might need to use different tools in trying to optimize the hardware. Here we’ll be focusing on Nvidia GPUs only and Bzminer.

We are going to be using the latest Bzminer v12.1.1 as mining software for the examples below and cover some of the popular Nvidia GPUs fo rmining with settings and expected hashrate and power usage. Obviously, we are going to be setting the GPU clock to a higher fixed frequency (oc_lock_core_clock) and the memory clock (oc_lock_memory_clock) to the lowest possible fixed frequency and we’ll add in the core offset (oc_core_clock_offset) to further lower the power usage by lowering the voltage of the core. In the examples below do not forget to change the pool if you want and also set your Radian wallet address in the place of the YOUR_RXD_WALLET, also do not forget that you need to run Bzminer as administrator in order to for the OC settings to function!

Nvidia GeForce GTX 1080 Ti GPU running at 0.565 GH/s hashrate with around 100W of power usage:

bzminer -a radiant -p stratum+tcp://stratum-eu.rplant.xyz:7086 -w YOUR_RXD_WALLET --oc_lock_core_clock 1550 --oc_lock_memory_clock 810 --oc_core_clock_offset 250 --nc 1

Some more useful tips for anyone that wants to experiment with these settings above. We have provided good starting point in terms of frequency and offset that should be stable on most GPUs, however depending on your specific hardware and conditions you might be able to go up a bit for extra performance or power savings or you might need to go lower for attaining good stability. If Bzminer crashes or restarts you might want to start by lowering the setting of the oc_core_clock_offset parameter, that would lead to slightly higher power usage. If lowering the offset does not help, then keep its value and try lowering the GPU clock a bit. The video memory setting is already at the minimum level, so there is no need to play with the clocks there.
