Innosilicon has put up for pre-order their new A4+ LTCMaster Scrypt ASIC that should be capable of delivering 620 MHS hashrate with 750W ot power usage according to the official information. This is an update from last year’s Innosilicon A4 Dominator Scrypt ASIC whih was capable of only about 280 MHS and had higher power usage, so a nice improvement for sure. The new Innosilicon A4+ LTCMaster is available for pre-order at a price of $3200 USD (60.355 LTC, 0.631415 BTC) with delivery scheduled for November 30th to December 10th for the current batch. The price is only for the miner with a minimum order quantity of 3 devices and Innosilicon also has offers available with a 1050W 110V PSU or 1600W 220V PSU, depending on the region you live in and the electric network you use. Payments can be made via LTC, BTC or Bank Transfer, there is 6 months warranty and shipping is only with DHL.
INNOSILICON A4+ LTCMaster Specifications:
– Hashrate: 620 Mh/s (+-8% performance, can be over-clocked at user’s risk)
– Power Consumption: 750W (+/-8%, normal mode, at the wall, with 93% efficiency PSU, 25°C temperature )
– ASIC chips: 288 pcs
– Size: (L)350mm*(W)125mm*(H)155mm
– Gross weight: net weight 3.83 KG (without PSU)

If you remember a while ago we have talked about the 550 MHS BW-L21 Litecoin (Scrypt) ASIC Miner as an interesting alternative to Bitmain’s AntMiner L3+ Scrypt ASICs. Unfortunately back then these were hard to order as there was a minimum order quantity of 100 units and not an easy and straightforward way to order them. This is apparently about to change as the manufacturer of the devices Biwang Electronic Commerce Co. (BW) has appointed the Australian company Block Assets Limited trading as HyperBit as their Worldwide Retail Distributor for the L21 ASIC miner. So finally some competition for BitMain in the home mining segment and more options for the small miners to get back into the Litecoin mining…
You can currently order the 550 MHS BW-L21 Litecoin ASIC miner from HyperBit at a price of $2690 USD in single unit quantities and get it delivered worldwide with a shipping set to start on 30th of November for the current batch of miners. The L21 is apparently the current leader in terms of performance Litecoin Application Specific Integrated Circuit (ASIC) miner on the market with 550 MHS hashrate and with just 900W of power usage. It is not clear what the situation with the power supply is at this point however, is there one included (no mention), but a PSU does appear on one of the product photos. Most likely you would need to buy the PSU separately, one that does provide at least 1000W of power and comes equipped with at least 6x 6-pin PCI-E power connectors. Do note that all orders are being shipped directly from the manufacturers location – Shenzhen, China.
BW-L21 Scrypt ASIC Specifications:
– Hash rate: 550MH/s (+- 10%)
– Power consumption: 900W (+- 10%)
– Cooling: 2pcs @ 3000 RPM
– Dimensions: 329mm * 127mm * 159mm
– Network connection: Ethernet
– Technology: 28nm ASIC chips
– ASIC chips quantity: 144 chips
– Operating temperature: 0 to 40 Degree Celsius
– Warranty: 6 months
– Weight: 4.8kg

New HDMI Display Emulators (Dummy Plugs) Available
11, Oct 2017
It seems that there is a new wave of HDMI dummy plugs coming from China at very cheap prices (At least if you order directly from there) that are based on the Headless Ghost display emulator. These HDMI display emulator devices just plug inside the main video card of your mining rig and simulate the presence of a display with up to 4K resolution. As a result your mining rig boots normally (if it does not boot without a display connected) and you can use a custom resolution when you are remoting the mining rig and/or not be limited by low resolution. It seems that the HDMI dummy plugs from China are mostly available under a brand called Fueran, though we’ve seen some photos with unbranded adapters as well (including some photoshopped images).
These new HDMI dummy plugs can be an interesting alternative to the commonly used HDMI to VGA adapters that most GPU mining rigs get equipped with, though do note that you do not get the option to connect any kind of display to them. With HDMI to VGA adapters you are able to connect a cheap analogue VGA connector equipped monitor or a KVM device for monitoring the rig directly or even remotely with an IP KVM for example. So the new HDMI display emulators just look cooler and take less space, but are not as functional and do not really come much cheaper anyway, though you can find them more expensive and you can even buy the original Headless Ghost at even higher price.
If you do not need the VGA output that the HDMI to VGA adapters also simulating the presence of a monitor, then these new HDMI dummy plugs might be just fine for you. The new HDMI dummy plugs are available through eBay and Chinese sites such as Aliexpress for a price that can go as low as $3-$4 USD, the prices in Europe or US is usually a few times higher than that. The only drawback when ordering cheap from China is that the wait time for the delivery can be inconveniently higher than ordering locally at a higher price.
