New Gridseed 19.2 MHS Scrypt and 520 GHS SHA-256 Dual Mode ASIC Might be Coming

gridseed-new-19-mhs-asic-miner

We got a tip from a reader that a new dual mining mode ASIC device based on Gridseed chips might be coming out soon. The device is supposedly capable of providing up to 19.2 MHS Scrypt and 520GHS SHA-256 is listed for with a price of $12888 USD on a Chinese online store and is being sold by a company called EastShore Trade. This is a pre-order and they claim the miner will be available “at the end of March”. The photo above of the actual miner does look Ok, though the photo itself and the claimed specifications do rise some doubts, so you should treat this information with caution for the moment!

This miner is apparently composed of 4 blades (only one blade shown on the photo or all 4 blades together?), each blade can mine at a speed of 130 GH/s for SHA-256 mining and 4.8 MH/s for Scrypt mining. So, the miner can mining at a speed of 520 GH/s for SHA256 mining and 19.2 MH/s for Scrypt mining in total. The total power consumption claimed is just 800W for the four blades and the power supply is apparently a part of the miner according to the information. The miner on the photo does remind us a lot in terms of design to the AntMiner S1 and the device apparently also comes with a LAN port, so it would be independent of a computer.

19.2 MH/s worth of Scrypt mining hashrate is achievable by using a total of 64×5 Gridchip GC3355 processors or a total of 320 chips providing 300 KHS each. With the total power usage of a non-overclocked 5-chip ASIC of about 5W we should be getting about 320W for Scrypt only mining mode if the calculation is correct. The problem comes with the SHA-256 mining part, with a 5-chip solutions needing roughly about 50W in BTC mining mode this would result in 3200W power consumption for the SHA-256 mining only or a total of 3500W without overclock for Dual Mining mode. So how come we see claimed 800W for the device, this could neither be the Scrypt only power usage, neither a single blade one (4 blades shod total in 3200W). And integrating a 3200W or 3500W power supply in a miner so small does not seem very believable (again is the photo of a single blade or of the 4 blades?). So do not be in a hurry with pre-orders at least until there is more clear information about this upcoming ASIC!

Updated cgminer 3.7.2 for Windows Scrypt mining on Gridseed 5-chip GC3355 ASICs

cgminer-3-7-2-gridseed-windows

We have compiled an updated version of the cgminer 3.7.2 for Gridseed 5-chip ASIC devices with some small fixes and have an option to try and overclock the device over the previously available maximum limit of 1000 MHz. Now you can try running the device at 1050, 1100, 1150, 1200, 1250 and 1300 MHz, though these in our experience going past 950 MHz will most likely produce only hardware errors, you are still welcome to try. So far 850 MHz operating frequency for Scrypt only mining mode seems to produce the best results with most devices, though you are welcome to experiment with yours. For a guide on how to install and use the Gridseed 5-chip ASICS with this cgminer. Also note that cgminer 3.7.2 for Gridseed does require you to replace the standard virtual USB to COM driver with WinUSB driver with the help of the software Zadig in order for cgminer to be able to detect and use the GSD ASIC devices.

Download bfgminer 3.10.0 for Windows Scrypt mining on Gridseed 5-chip ASICs

13, Mar 2014

bfgminer-gridseed-support

Another software miner now has support for the 5-chip Gridseed GC3355 BTC/LTC ASIC devices and that is bfgminer, though you should note that there is a separate branch that supports the Gridseed hardware and the official 3.10.0 release is not compatible. The version that you can download below compiled for windows is the one with Gridseed support and you can also use it for Scrypt GPU mining, though the command line we have provided in the BAT file is only going to start bfgminer and look for Gridseed devices (remove the -d gridseed option to use GPUs too). Also note that the command line starts the miners with 850 MHz operating frequency that should result in about 360 KHS scrypt mining hashrate (60 over the stock 300 KHS) – should be stable option for good overclock performance with low to no HW errors, but your results may vary. You can get down to 800 MHz if you are getting more HW errors, or try to get up to 900 MHz if you get no HW errors to see if you can get 380 KHS stable.

This version of bfgminer shoudl work with both the earlier 5-chip Gridseed ASIC devices as well as the newer revisions, it detects and work with our miners using both the newer STM32 Virtual COM port driver as well as the older CP2102 USB to UART Bridge Controller. Note that bfgminer requires the devices to be working with their standard virtual COM ports and not to have the drivers replaced with Zadig with WinUSB like cgminer does. If you have installed the WinUSB drivers you may need to Uninstall the drivers and unplug and plug the ASIC devices so that the default driver is installed again. Alternatively you can try to install the GridSeed.inf driver you will find in the miner archive. Note that the version of bfgminer provided here is only for Scrypt (LTC) mining on the 5-chip Gridseed ASIC devices!
