A recent small change in the Decred (DCR) protocol has apparently resulted in the old GPU miners not being able to mine anymore, so an update is required in order to continue mining DRC coins. There is already an updated version of ccMiner 2.0 RC3 from Tpruvot for Nvidia GPUs as well as the Nicehash fork of sgminer version 5.6.1 for AMD GPUs. So if you are mining Decred (DCR) and want to be able toc ontinue mining it make sure you update your mining software.

If you want to get more details about the so called Decred Pow Mining “outage”…

The development of some of the ccMiner forks for Nvidia GPU miners didn’t seem very active visually in the last couple of months, especially with coins such as ZCash (ZEC) that came with their own miner releases, but it hasn’t been stopped. A few days ago tpruvot has made a pre-release version of his new ccMiner 2.0 available (source) for people interested in checking it out with probably a few small things left to be ironed out before the final 2.0 release is made available. So if you are using Nvidia GPUs to mine crypto coins then you might want to give it a try and don’t forget to send a tip to your local friendly ccMiner developer for a beer or two to show your support.

ccMiner 2.0 RC2 changelog:
– Handle cryptonight, wildkeccak and cryptonight-lite
– Add a series of new algorithms: timetravel, bastion, hmq1725, sha256t
– Import lyra2z from djm34 work…
– Rework the common skein512 (used in most algos except skein ;)
– Upgrade whirlpool algo with alexis version (2x faster)
– Store the share diff of second nonce(s) in most algos
– Hardware monitoring thread to get more accurate power readings
– Small changes for the quiet mode & max-log-rate to reduce logs noise
– Blake2s fix, variant built with CUDA 6.5 (not usable for lbry)

Do note that this release may not contain the best optimizations and fastest performance on all of the supported algorithms, so depending on what you are currently mining you may need to stick to another faster fork of ccMiner or not. Also the CUDA 6.5 binary release does not work for LBRY mining as noted in the changelog, so either use the 8.0 release or compile with 7.5 for mining that coin.

At the moment Nvidia GPU miners have the advantage for mining X11-Gost with a faster hashrate for the more recent Maxwell and Pascal GPUs than AMD miners. Still AMD miners might be interested in checking out the X11-Gost algorithm used by SIBCoin (SIB) as it is not that power hungry and with the increased interest with the recent addition of the algorithm on NiceHash as it might offer a nice profitability for users willing to sell their hashrate and get paid in Bitcoins directly.

So if you are using AMD GPU mining rigs you might want to check out X11-Gost on NiceHash using the latest sgminer 5.6.0 Nicehash Fork (source). We are seeing a hasrate of between 7 MH/s and 8 MH/s on stock Radeon RX 480 and while still slower than about 11 MH/s on a stock Nvidia GTX 1070 the fact that the algorithm is not that power demanding and you can use lower power for the GPUs may make it attractive for some users, so do give it a try. Older generation of AMD GPUs may not be the best choice for this algorithm performance wise and the same pretty much goes for older Nvidia GPUs, but for AMD Polaris and Nvidia Maxwell and Pascal it is.
