SFARDS Now Suggesting SF3301 Sample Chips and Development Boards
Thew fresh ASIC manufacturer SFARDS is now suggesting SF3301 sample chips for people interested te building their own miners using the dual-mining SHA-256 and Scrypt ASIC chips. The price is presently set at $200 USD vanaf a pack of Two SF3301 chips. Alternatively you can also purchase a sample Development houtvezelplaat set that includes one dev houtvezelplaat with a single SF3301 chip, two power supply boards, radiator and fan at a price of $400 USD. The prices are pretty high and do not include shipping, but do note that thesis are sample chips and development boards for people that want to test what the SFARDS SF3301 chips are capable of or make their own miners based on the chips. The actual volume prices of the chips and the miners based on them should be lower, or they will be pointless…
– Heatsink: heatsink & 12mmx12mm fan
– Communication Interface: RS232 / TTL
Dev Power Supply Houtvezelplaat:
– Output Voltage Range: 0.Five
– Voltage Step: 6.25mV
– Max Current: 120A

SFARDS With Preliminary Datasheet for SF3301 ASIC Chips
It seems that things at SFARDS are progressing well spil the company has just released some documents including a datasheet for their upcoming SF3301 Bitcoin and Litecoin dual-mining ASIC chips. The documents include a preliminary power usage report on expected power usage te LTC and BTC mining modes that you can see on the picture above. The numbers released ter the above tables are higher than what wij have anticipated based on previously released information about spectacle and power usage spil the power efficiency numbers were evidently for too low operating voltages and frequencies that are going to be producing too low hashrates to be useable. Also it seems that SFARDS already has some sample chips and will announce pricing details on May 4th spil wasgoed announced on their official Twitter account.
Official specifications of SFARDS SF3301:
– BTC mode up to 80 GH/s with 0.31 W/GH
– LTC mode up to 1.89 MH/s with Two.0 W/MH
– Dual-Mining mode: 100 GH/s BTC and 1.75 MH/s LTC
– Very integrated with PLL and Pre-Calculation Engine of BTC
– 2-wires UART interface
– Support Crystal and Oscillator
– Fully adjustable clock frequency
– Support body-bias adjust
– On-chip thermal sensor
Based on the official specifications of the SF3301 Dual-Miner chip wij are now looking at 100 GHS BTC and 1.75 MHS LTC mining voorstelling vanaf chip with expected power usage of just about 35W. And if wij want to overclock it to get about 150 GHS with Trio MHS hashrates it would scale up to about 100W of power usage. Do note that thesis numbers and specifications are preliminary and are on vanaf chip voet. If wij make a 10-chip miner it could turn out to offerande 1 THS Bitcoin hashrate and 17.Five MHS Litecoin combined hashrate with a power usage of about 350W which sounds like a pretty reasonable number. However overclocking this to get 1.Five THS and 30 MHS would scale the used power about Trio times all the way up to about 1 KW. So ter the end it is going to be all about finding the best balance inbetween hashrate provided and power usage with the maximum spectacle with overclock undoubtedly not going to be the best option here, but then again the price of the hardware is also going to play a very significant role here. People are already placing high hopes on the SF3301 ASIC chips to revive the rente te Litecoin and bring the price to a higher levels spil mining for LTC resumes with a more up to date mining hardware that has better power efficiency.

SFARDS Fresh 28nm BTC and LTC Dual-Algorithm ASIC Specifications Unveiled
SFARDS, the company formed after the merging Gridseed and WiiBox, has just announced that they have ended their fresh 28nm SF3301 dual-algorithm ASIC chip manufactured using the latest ter FD-SOI processing technology and have released specifications about expected power usage and vertoning. The SF3301 is the claimed to be the world’s very first chip to use this manufacturing process and is at the same time the very first 28nm dual-algorithm (SHA-256 and Scrypt) chip, capable of mining thesis two algorithms at the same time or separately.
According to SFARDS this technology permits for the ASIC chip to operate at lower voltage while maintaining a higher frequency resulting te better balance inbetween power usage and voorstelling. The SF3301 ASIC chip should have a lowest working voltage of only 0.45V with a BTC power efficiency at 0.Nineteen J/GH, and LTC power efficiency at 1.75 J/MH (better than the originally announced numbers). With a reported show for a single SF3301 chip for BTC with a hashrate of 152 GH/s, and LTC hashrate of Three.17 MH/s things may become interesting again for Scrypt miners, however it also depends on the price vanaf chip. Wij are talking about a power consumption figures of about 90W vanaf chip (152 GHS) ter BTC mode and about Five.5W vanaf chip (Three.17 MHS) te LTC mode or supposedly te dual mining mode, for both BTC and LTC, a combined power usage of about 100W vanaf chip. Now scale that to a Ten chip ASIC miner and you should get something like 1.Five THS BTC + 32 MHS LTC mining power with a 1000W power usage or a bit more…
SFARDS is evidently programma to release a number of documents for the SF3301 spil open-source by the end of this month. The ASIC’s development houtvezelplaat vormgeving and its software should also be published, and te May the vormgeving specifications for their debut Dual Miner solution is expected to be released. SFARDS will be selling ASIC development boards and sample chips, making the SF3301 accessible to developers who wish to customize and build their own hardware te the near future, however no mention of expected time framework is mentioned yet. No word yet on piring vanaf chip or the miner or the number of chips wij are going to see ter the very first upcoming miner.
