[ANN] Sfards:SF100, the first 28nm Dual-Mode Miner is accepting pre-order now

I wonder if it will be possible to tune Scrypt and SHA256 separately? I'm guessing that it's just based on the frequency of the whole chip, so probably not, but it would be neat if we could crank up the hashrate on the Scrypt side while keeping SHA256 side more power efficient if Scrypt were to be paying better...

I've never even tried to dual mine with my original five chip gridseed, so this is hearsay at best, but it was my understanding that the two modes are completely separate and can be tuned as such. Can anyone confirm or clarify this? (tempted to try)

I have a bit of experience dual mining with Greedseeds 5 chip product. Each side can be "tuned" individually but they do NOT work reliably in "dual" mode. Miners will slowly start dying over time requiring a power cycle to get them going again. Since I mine in a remote datacenter without the ability to easily power cycle equipment I resulted to only using the scrypt side. On scrypt they are very stable running for months without fail. I have had mine running non-stop since they first came out.

Having just read the first 40 pages of this thread I am reminded of what Gridseed did with the release of their 5 chip product. They will absolutely try to maximize profits. Expect these new miners to initially be priced at a premium. There will be a limited number available and people will buy them. Once they ramp up production pricing will start to come down quickly.

The original 5 chip Gridseed was brought to market at around $300 and quickly declined from there. I am not at all surprised at the $1,129 price being discussed here. If they do not sell enough of their initial limited quantity it is very easy for them to adjust down.

It would be interesting to try and determine their cost including development and production to get an idea how low they can go before it stops making sense to produce them.

Edit: These would have to be priced at $183.41 for them to compete with the $999 ALCHEMIST 256 Mh/s miner since power cost is not a concern for me...strictly thinking about scrypt of course. Wink

Thanks for sharing your experience with them. As I have no experience with them. I will probably give them a try with group buy for 2 to 4 rigs if they will approve a group buy for someone in the US. My intent is still to have a mining operation in Washington State. Was planning on the 4th Quarter of this year of 1st Quarter of 2016. Now it's looking like 1st or 2nd Quarter of 2016. Who knows, I may end up with most of my equipment being SFards.

Thanks again for sharing.

well for scrypt the blades were good gear. starting price was 3k and they dropped to 500usd pretty fast.

plus the blades sucked so bad at 256 mining no one every did mine them that way.

If this gear is like that people will not be happy. and no one has seen them mine 256. or scrypt in a you tube video. be careful don't be quick.

or jump in and get a deal. No one knows.

I tell you if J4obberwocky gets his development kit running maybe he will let us know what the chips can do.

@J4obberwocky any luck with the board?

Well, the blades would blow up if you tried to dual mine, they didn't have enough power circuitry. The 5 chips and the stickminers were the only ones that were capable without releasing their magic blue smoke.
