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. 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.

@FUTURAMA,
What country or the area are you in? If in USA or some EU area, there may have a few OEM fans available for sale.
@BitmainWarranty I don't currently live in United States, but if you have some fans for S4 Antminer for sale, I can buy them with BTC and send them to my mailbox in miami. I suggest submit a ticket or email asking. They are very quick/good support team. - https://bitmain.zendesk.com/hc/en-us Or shoot a email to - info@bitmaintech.comIf they have OEM fans for sale I'm sure shipping to your Miami mailbox is not a problem. If you are no longer in warranty, these fans have worked great for me. I've had 5 fans total go out on me in my S4's. I've replaced all 5 with the following fan and it works great: That container it's in can be taken off of course before installing. Free Shipping... I've bought a total of 15 more of these fans for spares. I've thought about replacing all of the factory fans in my SP20's with these fans. They really are beasts. SERIOUSLY!!! Plus, they have the RPM's and CFM you need for the S4. Especially, in the Miami heat. https://www.youtube.com/watch?v=Wqc72EOuteUhttps://www.youtube.com/watch?v=RZL7lVcKhmAhttp://www.amazon.com/gp/product/B00HQ18UDA?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00

.... if there was some way to make a modular miner and just buy chips that would be the best solution I think.
Working on it.... sweeeeeet Only if ASIC's manufacturers will want to sell their precious ASIC's @ reasonable costs. Not 10x manufacture costs... Understandable... Not for everyone. I think that with my design and 20$/SFARD_chip this miner could cost 849$ (fast calculations). With easy (== cheap) upgrade in future,only one PCB to replace with screwdriver.... Sounds reasonable... Especially, if the hash rate is similar to that of the SF100. I like the sound of cheap and easy upgrade as well. That's what attracts me to the Miner's Edge rigs out of Austin, Texas. And the fact they are water cooled; except for the PSU.

Has anyone actually confirmed that the price raising temperatures here is correct? If so, does it apply to the 100 unit "bulk orders" or to single units? Also, does that include shipping?
No one has confirmed that. So, I'm deleting some of my previous posts until I know for sure. I don't want to jump the gun.

So we should expect a "big yawn" from the Bitmain marketing guys? No pressure to announce/release an S6/S7 product?
Yes, the yawn is contagious. yaaaawwwwwn

After reading that link I posted, I see nothing in it about next generation rigs by SPT online yet. Sorry about that. I can't remember where I saw that. I may have read it wrong the first time. I could have swore I saw some were online now and more is in the process of being made to go online.

Numbers: Income per day: 8$ Power consumption @wall (what efficiency PSU?): 960W Power consumption /24h: 23kWh Cost per kWh (1st calc): 0.08$/kWh Cost per kWh (2nd calc): 0.1$/kWh 1 day cost (1st calc): 1.84$ 1 day cost (2nd calc): 2.3$ Income /day (1st calc): 6.16$ Income /day (2nd calc): 5.7$ Price: 1129$ ROI (1st calc): ~183 days ROI (2nd calc): ~198 days
All calculations without difficulty (and price ofc) increase taken into consideration....
This pricing puts this pretty much in line with Bitmain's pricing. Fairly close anyway. This is assuming it actually mines at the hash rate advertised.

.... I'm curious... "Income / day" calculations... Was that BTC only or BTC and LTC combined?
Both combined. As SFARD announcement in 1st page... Okay, thanks! Just making sure. I suppose a large farm with $0.04 per kWH or less in power costs may consider jumping on it. However, bare in mind, the price does not include shipping.

One guy over in the "Group Buy" sub-forum suggested that it would take well over 386 YEARS to break even in terms of the miner cost. That was with the usual fantasy provisions of "free electricity and no difficulty changes".
While I expected a "premium" price, this is more "Extreme Premium" pricing.
Sounds like someone can't count then :s Under those conditions even a U3 would make $18,000 in that time. I saw that in a sub forum as well. I think they meant to put in a decimal point instead of a comma on the number of days. They also did not state their power costs.

It's my understanding they are getting chips from Spondooliestech. So, when SPT's chips are in new rigs mining [As they are now], we may see them begin development very soon
Ok, while more recent than before, it just clouds the issue further. What chips does Spondoolies have that are newer than the Rockerbox (SP20), and where are they mining with them? What's your source for this? Just a moment... Let me find it again.

They won't produce anything until the next Gen comes out (from their last post in the thread)
True, but the price will probably be more appropriate when they do come out.

I'd probably buy a few of these if SFARDS can get the pricing down to $800, and offer individual unit purchases vs. 100 unit MOQ.
I would also like to see some test units sent to trusted veterans on Bitcointalk, so we know what we're dealing with. Otherwise I'll hold out until Bitmain launches the S7.
Yeah, i wish we had a specific confirmed time frame for the S7 or whatever they will launch next. I'm starting to think that with the price of the BTC and the halving next year... i'm not sure if the manufacturers will hold on the launch of their new chips. I guess someone will pull the trigger first and the rest will follow. If Bitmain revealed a time frame for the S7, they would have a hard time completing their sells on the present S5 and S4+.

There is another option that occurs to me. Sfards could partner with Bitmaintech for a new gen Antminer powered by the sfards chips... Their announcement was vague enough that this could already be the case. Two chinese companies will already understand the dynamics of price wars AND collaboration. Both have been quite successful in their niches (yes, I realise that Sfards is technically a new company, but it's built on Gridseed's proven record).
That's not going to happen. Each mining company only has value if their chips are good. Investing in another's chips means you're not investing in your own, which means you will eventually fail. Its all about chips, chips, chips. You've also got the case where when you have the best chips, you sure as hell aren't going to share them. I would say, I have to agree with you, dogie. It is all about the chips!!! Could SFards, sell their technology? Certainly. BUT... It would come at a heavy price!
