falcon-cgminer-performance-results

Our testing of the 27 MHS GAWMiners Falcon Scrypt ASIC continues and in the last few days we’ve been moving the ASIC miner through different pools in order to check what is the actual performance that you can expect from it. If judging the performance based on what cgminer reports you should be looking at the WU reported speed as the actual one and not the one for the last 5 seconds or the average reported by the software. Though do note that the WU reported speed is for the last minute based on the shares submitted. To get a more accurate result we need an average that covers longer period of time such as an hour or even a day and you can easily get such results from a pool monitoring and reporting not only your current hashrate again based on the shares submitted in the last minute for example. Do note that the Falcon Scrypt ASIC from GAWMiners is essentially the same in terms of hardware inside as the ZeusMiner THUNDER X3 and should produce the same hashrate. So far the recommended operating frequency of 328 MHz seems to work very well, though the standard rating of the ZeusMiner ASIC chips seems to be 300 MHz. The results you see here are made using the 328 MHz operating frequency with a HW error rate hovering around 5%, slightly higher than we would want, but still acceptable and apparently the normal one for the Zeus chips.

falcon-24-hour-hashrate-ltcrabbit

Here you can see a 24 hour chart with the hashrate reported by the LTC Rabbit mining pool. The minimum average hashrate per hour we got at the pool for the 24 hour test period was 25674 KHS and the maximum was 29332 KHS with an average across the 24 hour period of 27882 KHS. A very good result and with that hashrate you can currently get about 2.5-2.6 LTC mined a day, not too bad with the difficulty recently going past 10 thousand, but not that great either with the current exchange rate for Litecoin. So mining LTC now and not selling it immediately seems like the smarter choice if you have decided to invest in larger Scrypt ASIC miner such as the GAW Falcon.

falcon-scryptguild-average-speed

Trying out the Scrypt ASIC miner at the ScryptGuild mining pool where you mine altcoins and get payed in BTC has shown us very similar performance. The average hashrate poolside was 27738 KHS and with it the expected payout for 24 hours of mining could get you around 0.05 BTC at the moment. So poolside we are actually getting a bit more than the 27 MHS promised by GAWMiners, though we are a bit short from the 28 MHS that Zeus claims for the THUNDER X3, but it is still acceptable. It is possible that with some tweaking that we can get slightly better results by lowering the HW error level. The quite high power usage of the miner however does not leave that much room for optimizing the cooling and squeezing some more MHz from the miner. We are not ready to give up, so stay tuned for more information as we continue to play around with the miner. It will be interesting to compare this miner with the A2-based 27 MHS mini miner that uses Innosilicon A2 Scrypt ASIC chips and we are hopefully soon be able to compare the two devices.

cloudhashing-new-prices

The Bitcoin cloud mining service Cloud Hashing has lowered their prices or to be more precise is now giving more hashrare for the same price. You can check their previous prices here and now you can get 40 GHS for $299 USD, 165 GHS for $999 USD or 600 GHS for $2999 USD. With the increasing Bticoin network difficulty you would expect that a cloud mining provider will give you more GHS over time or make the price per GHS lower in order to make it more attractive for new customers. And this is one of the largest Bitcoin cloud mining services, though not the most affordable choice where you can purchase contracts for 1 year periods of time. According to their official status the service currently has a hashrate of 3.23 PHS in their dedicated pool for customers of the cloud service.

They are pushing things even further and not only offers lower price per GHS, but also try to attract new customers from competitors. We got a word that you can get a 10% increase in hashing power or 10% off the contract price if you are a CEX.io user that purchases a cloud mining contract. In order to take advantage of this promotion however you will need to contact the service via phone (512) 758-7847 or e-mail at support@cloudhashing.com as the discount or extra hashrate needs to be processed manually. If you decide to try this promotion feel free to let us know of your experience.

ccminer-1-1-windows

The source code of the ccMiner GPU miner for Nvidia has been updated to version 1.1 with a “Killer Groestl” implementation that essentially improves the hashrate for Groestl and other algorithms that use it. So with the new version you should see improvement in terms of speed for mining quark, anime, x11, jackpot, groestl, myr-gr and nist5 coins with ccMiner. There is no official binary release available, but we have compiled one to test it and you can download it below. Do note that this official update does not yet include X13 support, there is an unofficial fork with X13 support available, but the next update should also include the code for X13. So with it there should also be some speed improvements with X13 mining as well, so keep tuned for more updates very soon from the author of the software.

Trying out the new ccMiner 1.1 on a GeForce GTX 750 Ti GPU has shown some really nice improvements in terms of hashrate from the previous release without the Killer Groestl implementation. We are now getting up to about 2700 KHS on X11 versus about 2200 previously, Groestl gets us close to 7600 up from 3300, for Jackpot from about 3900 to 5500 and Talkcoin (NIST5) from 4800 to 8200. So the speed improvements are really worth the wait and if you are mining a coin using Groestl with your Nvidia GPUs at the moment you should definitely update your ccMiner.

Do note that the windows binary you can download below is compiled for Compute 3.0 and Compute 3.5-5.0 cards (32-bit version only), so it will not work on older cards. If you are unsure what version of Compute does your video card support check the included GPU Compute Capabilities List file. It is also compiled with Visual Studio 2012, so if you do not already have Visual C++ Redistributable for Visual Studio 2012 you will have to download and install it, otherwise you may be getting error for a missing DLL library.
