No, not bad at all.
You guys have been responsive to the squeaky wheels, especially the ones with valid points and issues.
People sit up and pay attention when they see someone treated well by a company selling products they use.

I need a bit better BTC price, another drop in SP price, or a group buy to pickup a few more units, and I am not complaining about the price you are at, but I would order today if SP20 was at $370.00 EA or 3 for $1050.00.

Of course the business model changing to straight industrial co-op concerns me as a home miner. I hoped to cut my teeth through home mining and open a side business this summer strictly dealing with crypto in the community, help other home miners get started, and a few other ideas. If I have a hard time getting product from the best miner manufacturer it will be kinda hard to recommend them to others.

That is what I understood from Guy in a recent post, and I've heard about it and talked about it with other members.
Is that the true intent? In the future primarily dealing with Industrial accounts, or will you sell whatever unit you are building to anyone, but your focus is listening to the feedback from the big miners? I should probably ask Guy, hope I'm not putting you on the spot, and if you do not know the answer, what is your opinion, thoughts, how will it affect the future of Bitcoin mining, and how does it specifically effect decentralization?

Any official release of firmware 2.6.14 ?

I once saw 1680GH on one of my four SP20s (set at 0.75v and 12c intake), but it isn't typical.  It also does 1640s at 23c.  It hardly breaks a sweat doing it (very little thermal limiting) so there is probably plenty of room to overclock that one, but I'm not interested due to the efficiency loss.  That said, that same "overachieving" SP20 doesn't underclock anywhere near as efficiently as the others. 

On two others I see closer to 1600-1620GH at 0.75v which I consider typical for a SP20.  The last one I have is an "underachiever" which struggles to get 1550GH at 0.75v (with four different ASICs hitting thermal limits in the 630-640s).  Although an underachiever at top speed, that one for some reason can underclock far better than the others (at 0.62v I see 0.48w/GH at the wall on that one-- something the others don't even come close to).

Lately I've been running them all at max 0.72v as the optimum profit point for my power rate.  This morning's readings (low to high) were 1461-1500-1530-1546.

they are very much like gpus in that respect.  3 indentical gpu's will all have different sweet spots.

and all of they power a shit load of extra power when pushed to the max.

that said I have 9 sp20's.

 I never expected them to do 1700 or 1600 I wanted them to do exactly what they do downclock  to 1100gh and use .5 watts per gh.  I hoped to use 2 per evga 1300 g2 psu as I have quite a few of them from my s-1's then s-3's.

I am happy with them .

My Kia Forte can reach 120 MPH downhill on a straight run in the daylight with an empty road.

'1.7±10%' unfortunately doesn't necessarily imply that the 1.7 is typical, it may only serve as the basis for the tolerance modifier that follows it.  In theory a manufacturer could state "2.0±25%" and if every box delivered only runs at 1.55, they can just point to the fact that it falls within the specified range.

In this case I'm not sure where Spondoolies got the 1.7Th/s number anyway, unless they're overclocking the chips out of the box.  The specs state that there's 8 RockerBox ASICs in there, and the RockerBox specs state 200Gh/s.  8x0.2Th/s = 1.6Th/s.

Might be interesting for people to post their actual hash rates (without over-/underclocking) and compile a graph, but you'd need more than a handful of people to get anything of significance out of that, and a lot of people are already underclocking them anyway to get a better power to hash rate ratio

so no hope for hitting that 1.7 TH.. what temp is your unit running at?

If that is pretty normal for something that states its 1.7

Mines are running at 1.55 TH with like 950 watt (guess around 1050watt at wall) with fan at 30% and 40%.

If that is pretty normal for something that states its 1.7 thats pretty crappy, i have even upgraded to the new firmware so a little disappointing

Hey

Anyone know the best settings for a SP20, Im only getting 1.6th... system is cool ( 23 at the front ) tried a vast amount of settings but never seem to get it to stay at 1.7 or more..

Any help guys?

Does someone has good settings for SP30 to lower its power use.
I remember that it was possible to do 2.4kw and 3.9-4Th and/or 1.9kw and 3.6 TH (I am mostly interested in these settings).
Or is does it mimic the SP20?
