flypool-zcash-nvidia-cpu

Earlier today Zcash (ZEC) went live as expected and people are already starting to mine it, some of them probably are still not aware of the slow start with very small block rewards initially. Regardless, with what is available as miners at the moment there are pretty much two places where you would want to go for mining if you still haven’t done so. The first one for CPU mining and CUDA mining is Flypool that uses a modified version of NiceHash’s stratum miner available for download here CPU/CUDA miner for Flypool.

coinsforall-amd

For AMD mining you might want to head on to the Coinsforall mining pool that uses its own different protocol and has an OpenCL and CUDA miner. Earlier today Genoil has posted an OpenCL miner binary for Windows with stratum support, however it seems that his miner is still not ready for major use as most people are reporting issues making it work properly. We have tried his miner and also had trouble making it work properly, so if you have AMD OpenCL GPUs just go for Coinsforall for the moment and use their miner.

zcash-block-reward

Zcash (ZEC) is a new crypto currency project that launches officially tomorrow on 28th of October and there is already huge user interest in it and a lot of hype. Since ZEC coins will be mined and the development of miners and pools is currently moving very fast thanks to the significant interest from users you might want to be ready and up to speed with what is happening. What a lot of people still may not be aware of is the fact that Zcash has implemented a slow-start mechanism for the first 20,000 blocks (or about 34 days), meaning that the block reward will start at 0 coins and gradually move to the 12.5 ZEC reward in the course of the first 20K blocks. It will take a bit more than 2 days for the block reward to reach 1 ZEC and before that with the expected huge amount of hashrate thrown at the network right from the start the initial rewards for miners will most likely be very small. The linear rate of block reward increase effectively creates half as many ZEC in the first 20,000 block period resulting in 125,000 ZEC mined instead of the normally expected 250,000 ZEC for the first month of mining.

Now, regarding mining, there are already a couple of mining pools available (mostly running on testnet) and a number of miners and more work is currently being done on improving miner performance and increasing compatibility. It seems that the NiceHash nheqminer is currently a popular choice, even though it currently supports only CPU mining and CUDA GPU mining with OpenCL support apparently expected shortly. The original miner from NiceHash is hardcoded to support only their mining pools, though since the source code is available other pools have adapter it to work with them as well (you need to get a dedicated version of the miner for that). Have in mind that mining Zcash on NiceHash might be more interesting option for some, but not for other users as you will be getting paid in BTC instead of ZEC… remember that you are essentially selling your mining hashrate and getting paid in BTC and not mining ZEC directly with them. There is also the alternative of purchasing Zcash Cloud Mining Hashrate from Genesis Mining

nheqminer-nicehash

Here is a list of pools where you can mine Zcash (ZEC) when the mining starts tomorrow October 28th and get paid in ZEC coins, note that besides each pool there is a link for the miner that supports it. Do note that the list of pools is probably not complete, so if you find a missing one please post it in the comments, so that it can be added in the list. Make sure that the pool is already operational and running on the testnet and clearly states what miner is supported in order for people to be able to test it…

msi-geforce-gtx-1050-ti

A couple of days ago Nvidia has introduced their new lineup of GTX 1050 and GTX 1050 Ti GPUs, entry level for gamers and the successor of the popular GTX 750 Ti and the more recent GTX 950. We got an MSI GeForce GTX 1050 Ti 4G OC video card to give it a quick test and see what Nvidia has to offer with their new GPUs in terms of performance in some of the most popular crypto mining algorithms. While the GTX 1050 Ti may not be the most powerful solution for mining, the interesting part here is the lower power consumption per board just like it was back when GTX 750 Ti was released. So while it may not be the best choice for more serious multi-GPU mining operations, it could still be a viable option for a lower power home mining rig with 6x GTX 1050 Ti for example.

The GeForce GTX 1050 and GTX 1050 Ti are originally intended to be used without external power and have a TDP limit of 75W (because of the PCI-E slot), though we expect that there will be some companies offering more serious models with external PCI-E power. Do note that if you plan on building 6x GTX 1050 Ti GPUs mining rig you will still need to use powered extenders in order to avoid the possibilty of damaging the motherboard as the power draw from these will be significant.

When we consider the fact that the new GPUs are based on 14nm production process (the first GPUs to go down from 16nm to 14nm for Nvidia) and apparently do have some nice headroom for overclocking. We have managed to get +195 MHz on the core and +150 MHz on the video memory with the default voltages and what was limiting us from going further was the power limiter as the card was hitting the TDP and could not boost the operating frequency that much. Still the maximum frequency of the GPU it managed to hit briefly was 1911 MHz, so with higher power limit and with better cooling such operating frequencies might be available for constant boost.

Here are the numbers, comparing the performance of GTX 750 Ti, GTX 950 and GTX 1050 Ti using the latest NiceHash Miner software to get the hashrates of various popular GPU mining algorithms at the moment. As you can see there is a really nice improvement in hashrate between GTX 750 Ti and GTX 1050 Ti, maybe with some decent overclock the new GPU could even get to double the performance in some algorithms. Nevertheless the improvement from GTX 750 Ti is good in terms of performance and while there is also decent improvement from what GTX 950 offers, it is not that significant really. The main reason for that is the fact that specifications wise the GTX 950 and GTX 1050 Ti look pretty similar, even though they are based on different architectures it is much like the older one is just a bit slowly clocked and has somewhat higher power usage. Still the GTX 950 is pretty much in between the GTX 750 Ti and GTX 1050 Ti in terms of hashrate in pretty much all algorithms apart from Cryptonight where the weird result is most likely due to the lack of optimizations.

In the end the new Nvidia GeForce GTX 1050 Ti is really a good improvement over the GTX 750 Ti in terms of mining performance, you could probably get the a bit higher mining performance from 4x GTX 1050 Ti as with 6x GTX 750 Ti, and the power usage will be lower. You could still build a good mining rig with decent hashrate using 6x GTX 1050 Ti GPUs and do with a 600W power supply just fine. Of course, as already mentioned it might not be the best choice for serious mining operations where GTX 1070 would perform much better in terms of performance, but for home miners it could still be a viable option… just like GTX 750 Ti did when it first came out.
