I've experimented with hacking the sp20 to fan speeds below those supported. When the device isn't overclocked (0.66v max) it seems to run fine at 20% fanspeed without overheating despite ambient temps today being in the high 20s. Noise is always an issue and this helps a little.


could you pm instructions or a guideline for this?

@ spondoolies-tech    


   a 20%  and a 30% option are really good for this gear if you can put these in  a new firmware please do so.


I have 6 units now  all with low clocks.  I would go for as many as eight if I could do lower fan's via your settings page.

My lower clocked machine are around 620 watts
 1189 gh

this runs on a seasonic 760 watt plat psu and it is pleading with you for a 20 or 30 % fan firmware upgrade


I second this request. Fan setting of 20 and 30 would be great.
EDIT: apparently this is already done in version .33 of the firmware; Spond is ahead of us  Wink

Maybe a naive question.
What is stable working voltage (UL?) or vlt 1 or vlt2?
The suggestion is to set the starting voltage to no more than 10mv below the stable voltage.

My two SP20's are in a my small warehouse with people and phones in it.  They pleasantly run all day with a fan speed of 30 with similar under-clock settings to what you have shared, Philip (and thank you for that!).  I haven't tried 20 because I've been content with 30.  They purr along at 1330 and 1375, the 1375 on less power too - just a more efficient machine.  The past few days I have cranked the power and fans up when we leave for the day, and back down to the above when we return in the morning.  The over-clock versus under-clock is moot in the recent hashing economy.

However, speaking of over versus under clocking, I did some maths the weekend before last, when BTC was at $375 USD.  I figured then, that from a profit standpoint, if your power costs were below $0.135 kw/h over-clocking made more money.  At $0.14 kw/h, and above, under-clocking was more profitable.  If I recall, I used 936 kw per month for OC, and 518 kw per month for UC.

The SP20's dropped in price today because I bought three more yesterday.  You're welcome.  Wink

Don't feel to bad. I have one from the first batch and pricing that's the slowest out of the four I have.

I have had this happen more then once to me.   Ice fury usb sticks killed me and gridseed blades were bad.


 But in the case of sp20's  My timing was good.  all six are mining now during the paycoin rush.  Oh I tried 1 firmware update and set the fans to 20.  pretty nice

Hmm... I don't see the newest firmware in the Firmware Upgrade page though. "Latest available firmware version: " is empty.

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461

This may a question that has been answered but what is the price to ship an sp20 to the midwest usa (more or less)

trying to figure out if I want to dive in and get an sp20 ..running the mining operation I have as biz so can get
equip depreciation (IRS considers them computers) 5yrs 100% deductible off gross income thus a real (eventually)
25% off towards $$$ paid in real taxes (20% equip depreciation a year off gross income) after my 5 year plan on the biz.

anyway with that in consideration and likely no more home miners out of spondoolies in the future
figure I may just jump in..but need an idea more/less of what the shipping would be to get the real
price with the $50 coupon.

my zip is 56003 in case spindoolies on here is reading this and have access to such data

thanks

my understanding is that the SP31 is limited to 1250W per emerson1200 if its on 208V power?

looking to squeeze some juice out of it to get past 4.7TH with 50C temps on the backside

i get 4.8TH/s on mine at max settings - running 0.53w/GH all day long.

thanks just needed a ball park figure

if you buy one net is 728 after the coupon of 50 bucks.

if you buy 2 net is 714 after the coupon of 50 bucks. the coupon is 50 bucks either way but shipping for 2 is only 160

This may a question that has been answered but what is the price to ship an sp20 to the midwest usa (more or less)

trying to figure out if I want to dive in and get an sp20 ..running the mining operation I have as biz so can get
equip depreciation (IRS considers them computers) 5yrs 100% deductible off gross income thus a real (eventually)
25% off towards $$$ paid in real taxes (20% equip depreciation a year off gross income) after my 5 year plan on the biz.

anyway with that in consideration and likely no more home miners out of spondoolies in the future
figure I may just jump in..but need an idea more/less of what the shipping would be to get the real
price with the $50 coupon.

my zip is 56003 in case spindoolies on here is reading this and have access to such data

thanks




$119 to TX (77005)

thanks just needed a ball park figure

if you buy one net is 728 after the coupon of 50 bucks.

if you buy 2 net is 714 after the coupon of 50 bucks. the coupon is 50 bucks either way but shipping for 2 is only 160



using the genesis calc at 10% diff and my eventual 25% off equip as a biz and the 50 buck coupon and the shipping I more
or less exactly break even on btc buy vs btc mine with electric (using full 728 price to buy vs the eventual 583.50 usd price to
mine etc)

then again is diff gonna stay at 10% or below next year at least>>>>hmmmmmm

may just do it for a toy factor...but 728 for btc seems to give me the same btc as mining with elec etc (less the psu i'd have to get)
even again with my equip depreciation (damn elec why could I not be in WA state.....grrrrrrrr 2c elec etc)

ah toys.....(will have to ponder this the next 40hrs or so)

my understanding is that the SP31 is limited to 1250W per emerson1200 if its on 208V power?

looking to squeeze some juice out of it to get past 4.7TH with 50C temps on the backside

On mine one PSU runs at 1360 and the other at 1250W


Uptime:13649 | FPGA ver:62
-----BOARD-0-----
PSU[EMERSON1200]: 1392->1248w[1248 1248 1248] (->1235w[1234 1235 1232]) (lim=1250) 0c cooling:0/0x10000000
-----BOARD-1-----
PSU[EMERSON1200]: 1488->1356w[1356 1356 1356] (->1269w[1269 1269 1268]) (lim=1360) 0c cooling:0/0x10000000


i get 4.8TH/s on mine at max settings - running 0.53w/GH all day long.

Yes but you aren't on 208V you are on 230/240V
