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.
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…
We’ve been getting quite a few questions about where to order Gridseed ASICs from, so we have decided to compile a short list of places that offer Gridseed 5-chip BTC/LTC ASIC miners. Note that we cannot confirm the reliability of these distributors and resellers of Gridseed, simply because we have not ordered from all of them, so do treat this list with caution and be careful where you order from. A good idea is to start with a small order to test the seller first and then make a larger order for more units if you are happy or go to another seller. The best option would be to go for a company selling in your Country or Region, even though you might be able to get better prices with Shipping directly from China. The idea is that you could be able to get the miners faster and with less possible problems, especially if ordering from a seller you are not sure you can trust!
Gridseed, the official manufacturer’s website where you can order directly for the best price. Note however that they accept minimum order quantities and the quoted official price is about $158 USD per unit. The shipping is done from China, so it will be more expensive to ship to Europe or USA an there will be extra taxes to pay. This is a good option if you want to become reseller of Gridseed, not something a normal user would do due to the very high MOQ.
MinerEU, this is the only company we have personally tested so far and can confirm that we have received our order without problems and on time, exactly as promised. This seems to be the best place to order if you are based in Europe as they Ship from London, UK, however they do also ship overseas with orders dispatched from China to US and Asia. Currently out of stock with a new shipment expected to arrive soon, $235 USD per unit and lower prices for orders of 10, 30 or 50 units.
Miners World, a Netherlands-based online store selling ASIC devices (Europe) that has in stock only 10 miners package with all accessories, the price for the kit is € 2499 EURO. The site is not in English, so you might have trouble ordering from there, unless you are based in NL.
Hashra, claims to be a UK & Hong Kong based company, but is shipping only from China. Currently has on stock 10 miners pack with all accessories for $2425 USD and 20 miners pack with all accessories for $4835. Their website lists positions for only the miners in packs of 10 or 20 without extra accessories, but these are currently out of stock.
JustASIC, apparently a USA-based company shipping only to US. Claims to have one of the best prices for Gridseed ASICs at $165 USD, but you cannot order a single unit, you can only order packs of 20 units for $3300 USD ($165 per miner) with no extra accessories included, currently with available units on stock.
Zoomhash, apparently based in LA, Califronia, USA with local stock available. They do seem to ship worldwide as well, but they are probably a better choice if you are based in US and not somewhere overseas. The price per single unit is $214.99 USD without any accessories (we’ve seen a photo taken by us posted on their website of our early revision unit). You can also order 10 devices with accessories for $1999 USD, or 20 devices with accessories for $3899 USD and their store also has some other mining accessories such as PCI-E risers.
Hash Master, another company that seems to be based on Los Angeles, CA, USA. Apparently they do also ship internationally, not only in USA, but information about international shipping is posted in product pages. Price per single miner is $238 USD and you get only the miner with a USB cable, no PSU, but they do sell accessories separately as well, and for a single miner with all accessories including a PSU you will have to pay $330 USD. They also offer packs of 10, 20, 50 and 120 miners that include all of the necessary accessories to make them run without the need of a PC.
GAW Miners, a East Longmeadow, MA, USA-based company selling both the mining hardware and ASIC hardware and hosting services as their location. Also what makes them different is their 5 Day Delivery Time Guarantee and the fact that they claim to offer 24 hour support service to customers. No clear information about international shipping, though apparently they do support it. We were actually contacted a few days ago by the company’s CEO, who sent us some nice photos of their custom multiple unit miners in action – you can see one of these photos in the top of this post. The price per single miner they sell is $189.95 USD for a single miner with no accessories, a 10 miners pack with accessories is available for $1999.95 USD, and you can go for their custom miner packages consisting of more devices that are ready to provide you with 15 MHS, 25 MHS or 42 MHS of hasrate that include everything you need to setup and run the devices.
Helixminers is a Deerfield Beach, FL, USA-based company though it seems they also have a distribution center in Sao Paulo, Brazil, but the good news is that thy ship worldwide. For the moment the company sells only Gridseed ASICs, though they let us know that they will be reselling the ASIC hardware of many of the other companies that have announced to be working on such devices with shipping dates set of later this year. A single 5-chip miner currently costs $175 USD, ad the company also offers larger packages with 8, 16 and 24 miners including all accessories required to start mining immediately and you can also buy accessories separately if you wish to.
EyeBoot is a Hong Kong, China-based company that sells both Bitcoin and Litecoin ASIC miners. The prices of most SHA-256 ASIC devices are not very attractive, besides the ones of some USB ASICs, but the ones for Scrytp miners are lookign better. They do offer the single chip GC3355 Dualminer devices for $80 USD, the 5-chip ASICs for $140 USD fr a single device along with packs of more devices that provide you wiht a better per unit price. There is not much details about the shipping of products, but we presume they do ship Internationally.
UBERASICS is a Netherlands, Europe-based company that may seem like a good choice for ordering from Europe, though unfortunately they do seem to ship only to some Western Europe contries only and there is no option to pay with crypto coins. A single 5-chip Gridseed miner will cost you 189 EURO or 199 EURO with all the needed accessories, there is also an option to buy a 10 pack kits that will be a bit better in terms of price per unit and accessories separately.
USBMiners is another Netherlands, Europe-based company that sells not only Gridseed products, but also various other mining hardware in the form of SHA-256 ASICs and even GPU miners. They offer the single CG3355 chip DualMiner at a price of 79 EURO and a single 5-chip Gridseed ASIC will cost you 124.95 EURO and yo have options for multiple unit packs that should normally give you a better price per unit, though the prices for 10 and 20 unit packs are actually higher that for the same amount of units with the single unit price. The company does seem to ship Worldwide.
There are probably quite a few more resellers/distributors offering Gridseed ASIC devices that we did not cover here, we don’t know about all of them. Do note however that we have not personally tested any of the listed sellers, unless otherwise noted above, so we give no guarantees about these companies whatsoever. So regardless of where you decide to order proceed with caution and do not start with a big order directly, test with a small one to confirm that everything is Ok, before ordering more miners. We do recommend to use a local seller if possible and not order from overseas as this can be more expensive, cause delays and bring other issues as well, even if the price seems more attractive often the end result might not be worth it. Feel free to share your feedback if you have used any of these sellers and if you can recommend another one that is not listed yet.
