Get Your Gridseed Scrypt ASIC Miners Cheaper Now

6, May 2014

gridseed-g-blade-chips

With the Scrypt ASIC race heating up and things moving towards more powerful miners getting available on the market very soon the prices of the Gridseed ASIC miners are getting lower and lower. Gridseed even recently announced that they have stopped producing the smaller 5-chip Inifinity USB miners, though the larger G-Blades are apparently still being made. The good news is that the prices of the Gridseed ASIC miners are getting lower while the distributors and sellers are clearing up their stock, so you can get to buy them at some pretty low prices. We have checked and compiled a list of the latest prices you can buy Gridseed Infinity USB and G-Blade ASIC miners. Do note that while the prices are up to almost twice as low in some places compared to the prices few weeks ago, this does not guarantee quick return of investment, though it should be faster than buying at the old prices.

MinerEU currently has the small 5-chip Gridseed ASICs for $65 USD, the large 80-chip G-Blade at $960 USD and they have even listed the new Gridseed A2 ASIC miner based on the 28nn Innosilicon A2 Terminator chips, though that one is still pretty expensive at $12000 USD. These are probably the best prices you can currently get for Gridseed ASIC miners shipped from Europe.

GAW Miners is a great choice for buying from if you are based in USA. They currently have the smaller 5-chip Gridseed ASICs at $79.95 USD and the bigger 80-chip G-Blades for $949.95 USD. They do not yet have the new A2 listed, however they are already taking preorders for new more powerful Scrypt ASIC miners with their own branding.

JustASIC based in USA, but apparently shipping in EU too through partnership with MinerEU have almost the same prices as their partners. They do sell the 5-chip ASICS only in packs of 20 however in order to get a $65 USD per device price and the G-Blade is $940 USD, no other miners are available.

EyeBoot based in Hong Kong, China has their lowest price of a single 5-chip Gridseed ASIC at $110 USD, though for larger number of units you can get lower than that. They are still selling the G-Blade miner pretty high at a price of $1700 USD, so not a good idea to buy it from them at the moment.

Zoomhash based in USA currently sells the 5-chip Gridseed ASICs for $119.99 per single unit. They do have the G-Blade sold at the old price, however they do offer pre-order at almost half of the standard price if you are willing to wait up to about 10-13 days. They also have listed the new Gridseed A2 ASICs with a price of $11999 USD.

Hash Master also based in USA currently sells their 5-chip devices at not so attractive prices, but they do offer the G-Blades with 8 day pre-order at a price of $1089.95 USD. The company is apparently moving towards offering ZeusMiner hardware as they already have these listed for pre-order at their website.

Note that we have not listed all of the companies that do sell Gridseed ASICs and we have intentionally left out some that we have previously mentioned as they have either not yet reduced the prices or have stopped selling Gridseed devices completely. Of course we could have missed some as well as there are probably quite a low of companies that we are not aware of…

Raspberry Pi Controller Images with Gridseed ASIC Support

8, Apr 2014

hashra-controla-gridseed-web-interface-new

About a week ago we got our Raspberry Pi and started checking out the different available images for the device that could turn it into a mining controller for Gridseed ASIC miners. We have tried pretty much everything we were able to find available and it is time for us to report our first impressions from the different RPi images we have tried as well as some useful information that e have stumbled upon while trying them…

Zoom Hash offers a console-only based Raspberry Pi image in the form of a very basic solution along with a short guide and instructions for installing the image. Their RPi image is freely available for download, requires 4GB and contains a compiled cpuminer for Scrypt only mining. Easily configurable via a command line script. You can login with user/pass – pi/zoomhash.

MinerEU does provide a very basic console-based Raspberry Pi image with support for Gridseed ASIC devices. The company does not currently sell Raspberry Pi devices, so you cannot buy a ready controller solution with the software, but if you have the hardware you can set their image on your own and try it out. The image is 8GB, comes with compiled cpuminer and cgminer and does support scrypt only mining, there is no web interface, everything is controlled through the console. You can login via SSH as root user with username/password – root/minereu.

Hash Master does provide their Raspberry Pi image along with the device only if you purchase the complete controller package from them. We could not find their Pi image available for download other then the complete package they offer as a Pi-based controller with SD card and preloaded image on it, so we are not going to be able to test this image, but it seems to be pretty much Scripta with some visual modifications and the proper cgminer for Gridseed. We haven’t been able to test it, so we can’t report anything, though it probably handles well being based on Scripta (earlier version though). They do sell their RPi controller a bit pricey considering the normal price of the hardware you get.

Hashra provides a downloadable Raspberry Pi image for use as a controller solution for Gridseed ASIC devices. The version you can download from their website is 1.2, though you can easily update from the web interface to the latest version of the software (the web-based part) and we have done most of our testing with version 1.2.7 and there is a newer one also available. The good thing about Hashra is that their software is basic and easy to use and provides easy access for both scrypt only (bfgminer), SHA-256 (cgminer) only or dual-mining mode (cpuminer + cgminer). The drawback we did not like much is that there is no root access avaialble for you to have full controll, though there is a user fixed image available. The 1.2.7 was lacking the ability to overclock past 900 MHz, but the latest 1.3.3 version has that fixed with up to 1300 MHz selectable and a bit cleared interface. We like that solution quite a lot, though the load on the RPi and the lack of root access is a bit of a drawback, still probably the best option for dual mining. What is still missing as a feature is the support for backup pools if there is a problem with the main one you have set.

scripta-gridseed-support-web-interface

Scripta is our favorite solution so far at least in terms of features, especially after getting an image made by user that has everything setup and ready for use with Gridseed support, so no need to modify and compile things yourself. That particular image by mox235 is available here for download and it is really nice and easy to be used. Note that Scripta does support only Scrypt mining, you need a 4GB card, and the solution with mox235 comes with a modified version of girnyau’s version of cgminer that supports per device overclock via serial number (700-1400 MHz). You are able to pass individual parameters to cgminer, so no fixed drop down boxes to set frequencies for example, the web interface also does support reporting of serial number and device frequency, helpful when overclocking different devices with different frequencies. The image uses HTTPS for the web interface, though it relies on self signed certificate, so you will get a warning when trying to login, the default web password is scripta. You have full root access with user/pass – root/scripta. The thing that we did not like very much is that the miner control options do not seem to be working well, so when you change settings it is a bit frustrating to get them applied.

The best options you have are probably the Hashra and Scripta images for RPi, both seem to work pretty well, though you may still have some issues running them, especially if you plan on using a lot of Gridseed devices connected to them. It is important to monitor them carefully initially to ensure that your setup is working well before leaving the Raspberry Pi to handle things on its own. You are welcome to share your feedback and suggestions based on using any of the above RPi images with Gridseed support. Do note that so far we have been testing with a single Gridseed ASIC devices and we are now just going to add more miners to see how well will the Hashra and Scripta images going to handle more ASICs on the long run.

Using Raspberry Pi for Gridseed ASIC Mining Controller

30, Mar 2014

raspberry-pi-controller

We just got our Raspberry Pi and we are about to start testing the few already available mining images for the device that help you get started in using it for a Gridseed ASIC mining controller. You can of course start with a normal distribution and compile the miner yourself and set things up to run with the Raspberry Pi, however this requires some extra knowledge and time and not anybody can do it. On the other hand you have readily available images that you just need to write on and SD card and run them on the Raspberry Pi and supposedly you just need to configure the pool settings and you will be up and running in no time. Could it be that easy, or you should expect to have some troubles, we are going to find out soon enough. For now we’ll list the Gridseed optimized images that we could find available to use on Raspberry Pi, so you might want to give them a try as well…

Scripta is a Litecoin mining distribution for Raspberry Pi that provides a web interface for easier controlling, configuring and monitoring your mining devices. Originally it does not support Gridseed devices, but by replacing the supplied cgminer with a one supporting Gridseed ASICs you can easily make it work with Gridseed devices as well. In fact we suspect that most of the other images available below are based on Scripta based on some screenshots we’ve seen even though we still haven’t started testing any of them.

MinerEU does provide a dedicated Raspberry Pi image for Gridseed usb miner to their customers only. The image is now freely available, so you can download it and try it out if you are interested. We are going to give it a try for sure.

Hash Master apparently does provide their Raspberry Pi image along with the device if you purchase the complete controller package from them. We could not find their Pi image available for download other then the complete package they offer as a Pi-based controller with SD card and preloaded image on it, so we are not going to be able to test this image, but it seems to be pretty much Scripta with some visual modifications and the proper cgminer for Gridseed.

Zoom Hash does not give out much information about their image or even screenshots, but has a short guide and instructions for installing the image along with a download link available for everyone. We are going to be trying their image for the Raspberry Pi.

Hashra also does provide an image with some instructions to setup and use the Raspberry Pi as a controller for Gridseed ASIC devices. They do not sell RPi separately, but include it with their 20 miners package as a controller for the ASIC devices. They call their software for RPi Hashra Controla and it has web-based interface available.

This is it for now, time for testing the images. If you know about another Raspberry Pi image for Gridseed ASIC miners please feel free to share information about it so that we can include it in the list and also test it along with the others.
