ccminer-windows-jackpot

The ccMiner software miner for Nvidia GPUs has received an update to version 0.7 (source) adding support for Jackpotcoin and Myriad-Groestl. The new official release contains multiple versions for various GPUs, but do note that currently older Compute 2.0 hardware is not yet supported. Our test has shown a hashrate of about 7-7.2 MHS for mining Jackpotcoin on a single GTX 780 Ti GPU, so the performance you can expect mining JPC on Nvidia hardware is better than what the AMD GPU miner for JPC can currently provide.

Jackpotcoin (JPC) is a new crypto coin that uses a new hash algorithm called Jackpot Hashing Algorithm (JHA) and thus requires special miner software in order to be mined. The coin has a CPU miner available, but we are going to be skipping this one as there is also a GPU miner available already. The OpenCL miner for Jackpotcoin is based on the official sph-sgminer, but since the official release is not yet available with JPC support you need to use the fork for Jackpotcoin for now (source code). we have compiled a windows binary from the latest source that you can download below, our test on a single Radeon R9 280X GPU showed a performance of about 2.2-2.3 MHS mining Jackpotcoin, so it seems that Nvidia is currently the better choice for mining JPC on the GPU.

Primecoin (XPM) was one of the crypto currencies that was able to hold the front for no GPU miners for quite some time and it was only mineable with CPU however for a few weeks already it is possible to mine it with GPU as well. The first GPU miner “available” was Primegpu, supporting only solo mining and requiring the users to buy a license for the miner at 25 XPM per GPU it dd not seem very reasonable thing to do, so we have skipped it. The good thing is that there is already a new open source project that supports GPU mining, so far only solo mining, that may not be the fastest solution, but available for free, so you can test it yourself. The third GPU miner available is called Claymore XPM GPU Miner and this one has two versions, one for solo and one for pool mining with support for ypool.net, this is the miner we have been testing the last few days. Do note that this miner has a 10% developer fee that goes to the author of the project in order to keep him motivated to develop it even further and we consider this approach to be the much better choice than to have to pay for a license. The only drawback is that the miner is only available for Windows.

If you are wondering what version to use, then you should consider what is the number of GPUs that you have available and want to throw at mining XPM. If you are using one or two GPUs then you probably will be better off using the pool version at ypool as it should give you more constant earnings. If you are going to be using more and more powerful GPUs you may try solo mining, it has higher risk, but can also bring you much better profitability. We have tested the miner with a single Radeon R9 280X GPU at the ypool in order to see what we can expect to get for 24 hours and we ran the test for 48 hours. The reason for that is due to ypool’s way of calculating share value – it is accumulated for the last 160 rounds, so you start with lower earnings per block and after 160 rounds you can get a better estimate on per round earnings you are going to be getting if you continue mining. This way the first 24 hours will bring you less mined XPM coins than what you will get in the next 24 hours and after that, so give it a bit more time in order to see what profitability is going to be just like we did.

GPU mining Primecoin with a single Radeon R9 280X:
– First 24 hours mining at ypool: 1.78 XPM or ~ 0.136 LTC
– Next 24 hours mining at ypool: 2.31 XPM or ~ 0.177 LTC
– 24 hours mining directly for Litecoin: 0.1164 LTC

So it seems that GPU mining for Primecoin (XPM) can offer a nice boost in terms of profitability over direct LTC mining for the moment. And with some good luck and ore GPUs you might be lucky enough to get close to double the direct LTC mining profitability. Solo mining with more GPUs could also prove to be a good thing to try, but as we’ve said the luck there plays a much bigger role, and the higher the risk, the higher the chances for even better profitability as well. Solo mining is not recommended for a single or two GPUs as there the risk is much higher as it may take significantly more time to find a block and you may give up early and loose some precious mining time ending up with nothing.
