All About BTC, LTC, ETH mining as well as other alternative crypto currencies
Zoomhash, a USA-based company selling Gridseed ASIC miners has started selling voltage modified Gridseed G-Blade miners though they call them Zoom-Blade. The Blade Miners are available in two versions, a 6.2 MHS (VMOD1) that apparently can run at up to 925 MHz and 170W power usage and a 7.5 MHs (VMOD2) model that can work up to 1050 MHz with 300W power usage. There is no information about actual improvement in the power scheme of the voltmodded devices, only about improved cooling, so in our opinion if you are not very careful in what environment they are going to be placed you might have some trouble with these miners. Overheating and burning up voltage modified G-Blade miners is not that hard to get if you place them in a hotter environment and the cooling is not sufficient enough to handle the extra load.
Out experience doing a voltage mod of the G-Blade has shown that the miners are able to handle some extra voltage and be overclocked a bit with good extra cooling. Pushing them to 1050 MHz however could be more of a problem as the power block of these devices is definitely not designed to handle 150W per PCB, and even with some extra cooling you could still have problems with high temperature and that could easily lead to problems with the hardware. So we advice extra caution should you decide to go for a voltage modified G-Blade miner, or to modify your own miner. Zoomhash has apparently done tests, but if you place the miner at a place with higher ambient temperature you could still have issues with the proper cooling of the device. So be extra careful and monitor the voltage modified miners very closely at least the first 24 hours in order to be sure that they are staying cool and will be able to operate problem free for long time.
Minera is a new web-based frontend to monitor the Gridseed devices using cpuminer and it is designed to take advantage of the sandor111’s form of cpuminer that has many additional features as compared to the original cpuminer released with Gridseed support. Minera is designed to be used under Linux like on a Raspberry Pi mining controller or a Linux Debian systems, though it might work on others as well. Minera is only a frontend that comes with the cpuminer, all the rest you need to have already installed and running prior to adding the frontend to the mining controller or system you are going to be using.
Do note that this frontend is designed for Gridseed ASICs and the cpuminer only supports Scrypt mining using them, it is not compatible with other mining solutions, but since it is a free and Open Source software you can freely modify it to support other mining hardware as well. Definetly worth checking it out if you are mining with Gridseed ASICs and like the cpuminer fork by sandor111, but even if not interested in Minera, you can check out the latest cpuminer with TUI as it just got support for failover pools as a new feature, so even without a web-based graphical frontend this miner is a very good solution.
The last week of the month long photo contest we have organized together with our partners GAWMiners has ended and we have selected the last winner. The theme of the photo contest this time was Covert Mining – Operation CAMO and you can see the photos of the best submission we have received, the ones that have won a 5-chip Gridseed ASIC miner to the owner of this clever modification for mining with an Inifinity USB 5-chip Gridseed ASIC.
The person who won the third week award is Happydaze who has submitted photos of his interesting modification for a stealthy Gridseed ASIC miner hidden in a flower pot. Congratulations to Mark for his good idea and realization that has won him another Gridseed ASIC miner. And if you plan on doing a similar modification yourself do note that the flowers used are not real, so stay away with the water from this flower pot.
Here is how he has described his modification: “This is my Operation Camo Gridseed purchased from GAWMiners! This flower pot has been modified for maximum airflow while maintaining maximum stealth. The power supply is portable so you can take it with you in your car or boat as long as you have WiFi for for your laptop. It is an excellent way to get one more Gridseed into the house. The ladies in your life will appreciate your new found romantic side. You can also take it to the office and your boss will never know! You can covertly mine anywhere and everywhere with the Operation Camo Gridseed!”
If you missed your chance to participate in the photo contest, then unfortunately you really missed a good opportunity to show some interesting ideas and win a 5-chip Gridseed ASIC miner as this was our last week of the 4 week photo contest. But we are going to have more opportunities for you to win some cool crypto mining gear in the future as well, so stay tuned for more interesting things to come…
