First Impressions from the Gridseed 5-chip Scrypt Asic - Crypto Mining Blog

Yesterday wij have received our order of a single 5-chip Gridseed DualMiner device that is capable of Scrypt mining with a hasrate of 300 KHS spil vanaf the deice description, so wij have already played with it for a bit and are ready to share what are our very first impressions. A few days ago wij have also collective our Very first Impressions from the DualMiner USB Scrypt ASIC that uses a single Gridchip GC3355 processor. The single chip device did work pretty well and albeit it needs a bit more improvement on the software side, it is well designed and works well ter terms of hardware. So wij were impatient to attempt out the more powerful 5-chip version that wij actually don’t know how to call exactly yet – Gridseed Golden Orb, Gridseed 5-chip Dual Miner, Lightningasic DualMiner it goes by all of thesis names with some variations ter the color of the cooler – gold, silver, or crimson. The hardware inwards remains the same however, capable of mining BTC and LTC at the same time or only Scrypt cryptos such spil LTC with a higher spectacle then when working ter dual mining mode. Wij don’t care about the BTC mining capabilities of the device, so wij are going to concentrate only on the LTC (Scrypt) mining capabilities and vertoning.

From the outside the miner looks pretty good, so wij have opened it to see what is the build quality inwards the device – checking the components and the cooling vormgeving. Unluckily wij cannot say that wij are glad from what wij spotted inwards. While the PCB vormgeving is good and seems well made, the extra components on top and the wiring disappoint. Wij see masking gauze used to insulate components like for example the USB to COM houtvezelplaat, amateurish solution for the button next to the adapter power socket etc. Furthermore our unit had two of the wires from the USB to COM houtvezelplaat squashed by the bottom part of the cooler overheen one of the Gridseed chips. This could cause issues with cooling and can also create problems with communication inbetween the device and the rekentuig feeding it with work, so wij had to fix some of the wiring and insulation te order to avoid possible problems te the future. Wij can say however that wij do not truly like the build quality for something that is presently sold fairly expensive, it seems amateurish and like it has bot assembled te someone’s garage without adequate quality control. Wij truly expected more, especially after eyeing how good the single chip USB miner wasgoed made…

After fixing the hardware inwards the miner it wasgoed time to fire up the device and attempt it out. So wij had to look for some instructions how to use it spil well spil drivers and mining software (no documentation or software wasgoed included). Wij actually had some trouble having the miner decently recognized on half of the computers wij have attempted – the drivers did not function decently or did not assign a COM port for the device – it is connected via a USB port. Then to our verrassing wij’ve had to use a modified version of cpuminer that will work with the device and that software is truly lacking advanced features that are found ter the likes of cgminer for example. The miner software even does not give you a local report on the actual hashrate of the device, it only shows 0 KH/S, so you have to rely on the hashrate reported by the pool. There is also no adequate information about stale shares or hardware errors, so on the software miner side there is much work to be done for decent user practice – wij need at least a latest version of cgminer modified to support the ASIC device.

Moving to the power consumption of the 5-chip Scrypt ASIC miner. By specifications the device should consume about 8W for Scrypt only mining and 60W for Scrypt and SHA-256 (LTC and BTC) combined mode. Wij are only interested by the Scrypt mining functionality of the device, so wij expected to see very low power consumption, but to our verrassing the watt peettante demonstrated 56W. It seems that even tho’ wij are not mining BTC with the miner that functionality is still active and the miner consumer power spil if the device is working ter both BTC and LTC mining mode. Wij’ve read that there is evidently an update released to fix the power consumption punt, but only released spil a source code for the miner and you need to be able to compile it yourself – hardly anything that most miners are able to do by themselves.

So to conclude our initial impressions. It seems that thesis 5-chip Gridseed Dual Miners are far from ready for release to end users, however the company (companies) making them have rushed them on the market due to the user request. They do not seem well enough built with good quality control, the mining software is te a very basic form just to say it is available and works. There is no detailed documentation for setup and use, so you will have to figure some things by yourself… not to mention any support, so if you have a problem you will have to rely on the mining community for help. It seems that thesis 5-chip Gridseed ASIC devices are not even ter Beta, they are more like an Alfa stage product rushed to the market. Wij suppose that Gridseed did not even consider using thesis spil a separate units, but had ter mind to sell them ter packs of Ten or 20 orbs with an extra controller that they will be connected and managed from. Wij’ve ordered a single unit just to attempt it out before determining is it is worth go for a Ten (Trio MHS) or 20 unit (6 MHS) solution, but after reading about issues people are having with thesis and having issues ourselves with the single orb devices wij can say that wij are not glad with what wij got for our money. Wij expected much more and actually a finished product, not some half baked solution that you can hope will work somehow and not cause you issues. Wij cannot recommend to an average user or miner thesis devices at all, if you are a technical man with a lotsbestemming of practice and skill te mining and miners (including software) you might like the challenge however. The single chip DualMiner USB ASICs however are a much more finished and user friendly product, so you might want to check thesis out for now and stay away from the thicker 5-chip devices until they become a more finish and decently working solutions.
