Do you remember the 19.2 MHS Scrypt and 520 GHS SHA-256 Dual Mode ASIC that we have reported about being available for pre-order form a Chinese seller. We have expressed our doubts about that product and it turns out it will not be available by the end of this month, though the seller claims it is something that Gridseed is currently working on. So we might actually see the product in some form available in a bit of time, but for now you can be rest assured it is not going to hit the market anytime soon. If we see the 19.2 GHS Scrypt mining ASIC in a few months however it might be a bit too late as other ASIC manufacturers are already promising shipping date for more powerful Scrypt miners to be out before the end of the year…
Below you can read the official quote from the seller as a response to the user interest in the 19.2 MHS miner that they have listed for pre-orders:
Dear customers,
Thank you so much for your interest in the super miner (520GH/19.2MH) shown at our store before, we decided to take it down before more information is available.
We got this product info from an agent of Gridseed. And we were told that the miner would be available at the end of March. So we put it at our store. Unexpectedly, it has generated a lot of interest and doubts alike in the mining circle. And we have received messages from a lot of customers, who are both interested and doubtful, which is very understandable, because the information was limited and no one has actually used this product yet.
And we have to clarify one fact: WE ARE NOT SCAMMERS. Firstly, we didn’t take any order of the product. None. Secondly, we have been receiving very positive feedbacks from our customers. Anyone who has worked with us knows that we are an honest store. Thirdly, it was not intended as a marketing ploy either. We saw new products coming, we put them at our store, that’s it.
So under these circumstances, with the attitude of being responsible to our customers, we decided to take it down until more information is available.
At the same time we are requesting for more info and wait until we know better.
Thank you so much.

When we’ve made our previous guide for dual mining BTC and LTC on a Gridseed 5-chip GC3355 ASIC we’ve only had an earlier revision of the miner that used CP2102 USB to UART Bridge Controller. Now that we already have a newer revision with the STMicroelectronics Virtual COM Port we have decided to update the guide with information on how to Dualmine on these ASIC devices. Note that we do not recommend using these devices for dual mining mode, but for Scrypt only mode instead, but you are free to decide for yourself. The advantages of using Scrypt only mode are the low power consumption and heat, the ability to overclock higher, including with a voltage modification and a choice of multiple more up to date software miners. Note that the only way for the moment to use the Dual Mining mode on the Gridseed 5-chip GC3355 ASIC devices is to use the special version of cgminer 3.8.5 for BTC mining (SHA-256) along with the special modified version of cpuminer for Gridseed for LTC mining. Due to the way that the Dual Mining mode is realized on these ASICs using a more recent version of cgminer or bfgminer for LTC (Scrypt) mining on these devices along with the cgminer for BTC mining is not possible at the moment.
– Open up Windows Device Manager and go to the Ports (COM & LPT) and note the COM port that is written behind the STMicroelectronics Virtual COM Port driver
– Download and run the latest version of Zadig
– From the Zadig interface select Options and choose List All Devices
– From the Dropdown list of devices select STM32 Virtual COM Port and click on Replace Driver with the WinUSB driver selected
– Download the dualmining package that we have prepared for windows that contains cgminer 3.8.5 for BTC mining and cpuminer for LTC mining
– Edit the BAT files for the two software miners included in the archive with your settings for BTC and LTC mining pools
– In the LTC-START.bat file you will see an option “gc3355=\\.\COM4”, here you need to change the COM port number to the one you have seen in the device manager before updating the driver with Zadig to use WinUSB
– First you need to start cgminer 3.8.5 for BTC mining, wait a few seconds until the software starts up and connects to the pool and starts working
– Then start the cpuminer for LTC mining, note that you will need to wait for some more time here before the miner connects and starts working, but it it takes more than a minute maybe something is not right
If you still haven’t used cpuminer for Gridseed you should know that the software does not report local hashrate, so the zeroes you see are normal, it is actually working and sending shares. Also note that when in Dual Mining mode you will not be able to overclock the device as high as when only in Scrypt mining mode, so it is normal to be getting lower hasrate. As we’ve already said, we do not recommend the Dual Mining mode and suggest to use these ASIC devices for Scrypt mining mode only, especially if you want to run multiple devices.

KnCMiner has just announced their first Litecoin mining ASIC device already available for pre-order with a Q2/Q3 shipping date, 100 MHS minimum Scrypt mining hashrate and a price of $9995 USD (without VAT). Not much information is available for the moment, but trusting KnCMiner is much safer than Alpha Technology who have not yet released a product on the market, unlike KnC who have some history and good feedback from users that have purchased Bitcoin ASIC devices from them. Note that Alpha Technology has also announced target for shipping for Q2/Q3 this year, but their Scrypt ASIC devices are rated at up to 25 MHS and you will need to pay £5450 UK pounds (without VAT) for that. So if you haven’t pre-ordered a Viper Scrypt miner from Alpha Technology then it is much more reasonable to go for the 100 MHS KnCMiner Titan Scrypt ASIC. Meanwhile Gridseed remains the only company currently making Scrypt-capable ASIC devices and shipping them on the market, so that is the only option you have for the moment for an LTC ASIC device. It is also interesting to note that current customers queuing for a Neptune SHA-256 ASIC are able to exchange their queue if they are more interested in the newly announced Titan Scrypt ASIC miner.
