We have received some SkeinCoin (SKC) from a reader to give away for free to visitors of the blog that are interested in some free coins. The idea of course is to rise the interest in SkeinCoin a bit as apparently the coin needs it, so don’t miss your chance to get some free SKC coins. SkeinCoin (SKC) is a Skein-SHA2 alternative crypto coin that can be mined with both CPU and GPU and there is support for mining it with both a fork of cgminer and sgminer on AMD GPUs as well as with Nvidia GPUs using a more recent version of ccMiner.
So getting back to the SkeinCoin (SKC) giveaway, all you have to do to take part in it is to post your SKC wallet address in the comments below and you will get 80 SkeinCoins sent to you – that is the reward you will get if you mine 10 SKC blocks at the moment. Do note that since all of the coins will be sent manually to you it may take some time before your reward is received, but normally it should not take more than a few hours. Only one reward per user is allowed, so please do not abuse our giveaway – we have more than enough coins to give away, but we reserve the right to cancel the giveaway at any time we decide.
The giveaway of SKC (SkeinCoin) is now officially over, we have sent to users 1840 SKC in total.

The latest high-end GPU from AMD, namely the Radeon R9 Fury X, that has been just recently announced has managed to provide performance high enough to be equal to the competition in the form of the Nvidia GeForce GTX 980 Ti… at least hen we are talking about using video cards based on these GPUs for gaming. We already did some benchmarks to see how fast the GeForce GTX 980 Ti is for mining, so it is time to see if the Fury X will be able to compete with these results like it does for gaming. An interesting advantage that the Fiji GPUs used in the Fury X video cards is that they come with HBM memory and both the video memory and the GPU are water cooled. In theory this means that you get lower temperatures and silent operation and the Fury X does manage to provide that. One more thing that you would normally expect from a water cooled GPU is to have a lot of potential for overclock, but unfortunately this does not hold true for the Fury X or at least not with the first card out on the market at least. We barely managed to squeeze out just about 75 MHz extra from the GPU and there is no option to overclock the video memory for the moment.
So off to do some tests with some of the popular and more profitable algorithms for mining lately, we have used the latest sgminer along with some of the optimized forks available for different algorithms such as the one optimized for Quark and Qubit. Note that there are not yet specially optimized kernels for the Fury X or settings that work best, so we were trying to use ones that we are familiar with already from the 280 and 290 series from AMD. So some of these worked really well, while others not so well and the generally available OpenCL kernels did provide quite disappointing results actually…
AMD Radeon R9 Fury X Results:
– X11 default: 6.778 MHS
– X11 Wolf0 Mod: 8.123 MHS– X13 default: 5.614 MHS
– X13 Wolf0 Mod: 7.176 MHS– X15 default: 4.69 MHS
– X15 Wolf0 Mod: 6.335 MHS– Quark modified: 22.37 MHS
– Qubit modified: 21.15 MHS– Neoscrypt default: 147 KHS
– Lyra2RE default: 287 KHS
– Lyra2RE Pallas Mod: 450 KHS
As you can see the results are a bit disappointing at this point, everything apart from the Quark and Qubit performance using the modified 280X kernels where the performance is really good and similar to that achieved on the GTX 980 Ti. Other modified/optimized kernels such as the ones for the X algorithms from Wolf0 or the Pallas mod for Lyra2Re do increase the performance a bit, but it it still disappointingly low. In fact on some algorithms you can expect to get worse results with Fury X than with a 280X for example, so we need to find better settings and maybe get optimized kernels especially for Fury X in order for that card to be viable for crypto currency mining. The only thing it is good for at the moment is for mining coins using the Quark and Qubit algorithm with the modified kernels, but then again buying a GTX 980 Ti instead could be the wiser choice for generally better mining performance for any algorithm supported… at least for the moment.

Time for another update of the complete packages based on the Miner Control tool for Nvidia GeForce GT 750 Ti and AMD Radon R9 280x GPUs due to the latest developments in the mining world. The latest versions you can download from the links below include some updates and it removes the YAAMP pool support as it has become a part of NiceHashand currently redirects to their stratum servers. The latest updates also includes the most recent versions of SP-MOD’s ccMiner for Nvidia Maxwell as well as the sgminer fork with increased performance for Quark and Qubit with pre-compiled Binary Kernels for 280X. The two Miner Control tool packages are based on the latest fork of Miner Control from KBomba version 1.6.4.
To be ready to use the packages you just need to update the account settings for each pool to reflect your BTC payment address. Do note that the default configuration that we have set is mining from time to time for the author of the software (Miner Control) as a donation alternative, but you can change that setting should you wish to. The packages are ready to be used with either AMD Radeon R9 280X or Nvidia Geforce GTX 750 Ti cards, but you can also us the Nvidia package for other GPUs or more cards – what you may need to reflect however in the config file is the total hashrate and power usage. Since the AMD packages contains not only specific settings for AMD Radeon R9 280X, but also pre-compiled binary kernels specifically for that particular card if using it with other GPUs you will actually be getting lower hashrate, though n problem to use it with multiple 280X cards.
