Excellent work.
I am looking forward to the SP30 so much.  I love the design.  It makes it great for rack mounts and easy cooling.
The performance is awesome.
Keep up the great work guys.
Zvi you are a god.  Thanks for the hard work.

Small debt to Zvisha (going over my hundreds of emails...)

The hybrid SP30 (SP30 Mgmt, SP30 Mainboard, AlteraFPGA emulating RockerBox ASIC) is working perfectly.
The sw is ready, just waiting for the ASIC ...

Voltage over 140 is enough for max performance.
There is only one machine under-performing (slightly) - number 4.
I guess it has DCR type 1 which works well in sub-25C and becomes bottle-neck at higher temperatures.

Yeah:) But I would like to have those figures near 1.47  Grin

QG, please, post your settings.

1, 2 and 6 are already running at maximum supply current (from the PSU).

Do the other ones maybe have a little increased temperature? It is hard to read from the text, as the fomatting gets messed up.

Thanks Collider.

By the end of the next week, I will have temperatures near 25. Before then, I guess, I can do nothing about it.....

with something like the above...could you put a bunch of fans in and run it up and give us a guess on how much noise this bestie is gonna make

(yeah no data center plan to use heat eventually to heat house i'm sooooo cheap)

not sure if above makes sense but 6 fans or whatever going in the closed case MAY give us some idea of noise?

also what brand fans are you using ..if you give us customers notice we can perhaps dig up an 'optional' fan quieter that we may want to add
instead
(every little bit helps)

anyway any info would help on this for us 'dumb home users) that are hoping the bedroom is far enough from the bsmt for all this to work out

i happen to have a pre-May SP10 and 2 x May SP10s. Pic on left is pre-May (gaederopus) and pic on right is slow May batch (princeps). Although, it should be noted that i have the SP10 s hosted in very different locations and it's not the best situation to compare as one unit (gaederopus) has a bank of 8 chips down. but you'll get the idea.
Left is gaederopus (pre-May) hashing at 1.47Ths. Right is princeps (May slow) hashing at 1.43Ths
Left is gaederopus (pre-May) with DCR = 0x0. Right is princeps (May slow) with some DCR = 0x2
Cheers,
QG
Can I please have the settings and firmware version for both? Also, any additional info, that is relevant Smiley
Thanks!

Early estimations shows that from 1m distance noise level will be ~68dB (PSU side, fans at 80%, power supplies at max load)
Under same conditions, the SP10 noise level is ~74dB
We will have exact numbers only when the ASICs arrive

Nice to see that you are going with some maximum cfm fans.

This should put the airflow of the sp30 to a maximum of around 400cfm, which is more than 2.7 times that of the sp10. (While hopefully only using around 2 times the power)

This should give everyone some more peace of mind, as it should make the sp30s´ performance less temperature dependant and deployment in some less perfectly cooled facilities available.


The change in DB is around a factor 7 decrease in noise level, which is really nice. The sound quality should also be different, with less of a high-pitched whine.

well found this db level of a couple heat pumps one 93 db which really sucks

the other around 69db

anyway should be ok in my bsmt using this as a 'ref' of sorts

youtube

http://www.youtube.com/watch?v=4QAKPvG0P1M

also found this from a chart

70 Loud                   Average radio, normal street noise, vacuum cleaner

60 Moderate             Conversational speech

50 Moderate             Window Air Conditioner

well it will be in the basement I'm on the 2nd floor..but maybe I should look (or we should look) into some kinda 'sound proofing' huh?

my bsmt is old limestone block 10' high type upper midwest bsmt

no house a/c so will likely put an a/c in basement window for aug (titan from knc on order) and sept (sp30)

with hopefully?Huh little use of the a/c unit  just maybe aug and 1/2 of september...can get by with heating house after those months?

with any extra heat after that point is less for the furnace  (knock wood)

probably not my wisest move

Well, i don´t know the average temperature in August but if your basement has some kind of window (or there is enough heat transfer through the walls / into the rest of the house)
You could be fine.

Some kind of portable AC should come in handy though, if your gear arrives in August / September.

You can still see and buy one then, though.

Is your home electricity price so good?

it is 15c kwh but with the elec load the elec co said i can get commercial rates for my house even...the fees are higher the kwh is lower..but i may
be able to knock it down to 12c kwh realistically

(note: my util says my kwh is 8.6c kwh but it almost an even 15c kwh when you add taxes/fees...so that is deceptive will have to carefully look it over see if it is worth it)

anyway co-hosting was about the same price then add setup and shipping etc did not pay for me in that i likely will be heating the house (or could) middle of October

interesting times

Performance will always be a function of temperature, because you'll want every tiny bit of extra performance which doesn't cost you significant power. Getting the ASICs 5C cooler facilitates that.

SP10s were only 'annoyingly' loud because of that darned bugged PSU fan, the actual unit's fans are fine at 40%.

yeah well again it was same price more/less for hosting...and did not need 6 month hosting 1 month down setup fees and shipping (approx 350 bucks) if/when i will need
the heat from the beastie in oct/nov or so to help heat the house (ie can open the bsmt window heh)

but think if i just put in a window a/c with a regular foil a/c wire mesh a/c coil ducting (flexable) and just have it loop over the top of the sp30 and pour a/c air on such
from my 'high' basement window with the window a/c unit (which was given to me think it is 12k unit) all should Huh be well

but yeah with diff rises looks like i will do a lot of work just to get to the same amount of btc i coulda/shoulda go by going and buying at www.coinbase.com

gonna be quite the dump on difficulty 25% this last pop an hour or so ago and estimate already of another 25% plus on next diff rise

again interesting times

well if btc goes up in USD past 700 usd I should be OK and make $$$ over equip purchase but 'knock wood' should be ok....but hate using btc rises to 'prop up' a miner
buy

even my knc jupiter 550gh last oct making say 49 btc was not a good choice in that I'd have 80 coin if I'd had just bought coin last july when i paid for the beast

but at least then I had an excuse..ie newbies never drop 7.5k (with power supply) on coin direct....have to jump in with equip seems most of the time I was no exception

but www.coinbase.com and the occasional buy is looking very attractive....too much drama the last year etc....imho

It looks likely it all has moved past the home asic miner and into large commercial farms at this point (now i know how the gpu guys feel)

hold at that point i guess and itty bitty miners for fun if any at all in 2015

~snip
That is why it says less. Cooling capacity is ΔT* airflow.

More airflow should guarantee proper cooling even at higher temperatures, or the extraction of more heat at equal temperatures.

Airflow is equally as relevant as temperature, and installing better fans is easier than cooling down a whole building Wink

This assumes the same surface area of coolers, aswell as equal materials used (sp10/sp30).


@spondoolies:
Have you gotten any information about the maximum performance of the ordered PSUs?
I assume they have a little less headroom than the ~+20% of the sp10s PSUs?
