Zcoin (XZC) has recently switched to a new algorithm called MTP as a means to be ASIC-resistant, it is a new algorithm and mining software is still being developed, but there are already miners available for CPUs (not that useful anymore) and GPUs – for both AMD and Nvidia. If you are interested in trying out to mine Zcoin you should be aware that the algorithm needs more memory, both on the GPU (4 GB VRAM on the video cards as minimum) as well as on the mining rig where 8 GB plus is a must have preferably 16GB for 6-8 GPUs. Also you should note that miners are still being optimized, so performance and stability can be further improved and you can expect to have some issues at this point. if you want to try out the CPU miner for MTP you should be aware that it also needs a fixed 4 GB per thread so with an 8-core processor, you would need 32 GB of RAM.
If you are using Nvidia GPUs for mining you should head over to the ccminer fork with MTP support being actively developed by djm34 and download the latest version. Depending on your settings the current version should be capable of providing about 1200 KHS per GTX 1080 Ti GPU with lower power usage (not yet fully optimized), owners of RTX 2080 GPUs might be quite happy with up to almost double that hashrate, but with higher power usage though. Make sure that you have the latest Nvidia video drivers installed though with CUDA 10 support in order to be able to run the miner.
If you want to try mining ith AMD GPUs, then you will need the latest WildRig Multi 0.15.0.6 mtp beta miner that adds beta support for the MTP algorithm. AMD RX 480, RX 580 and RX 590 GPUs should be capable of delivering about 800-900 KHS per card which is quite good compared to the current Nvidia results, however the power consumption is higher on the AMD video cards as well. The AMD GPU miner for MTP also has high requirements for both video memory and system memory, so make sure you have enough available on your mining rigs. If you have just 4 GB of system memory availabe you can still experiment with the miners to see what performance you can get, but you should limit the miner to run on a single GPU only.
