The SP20 can be under-clocked to ~0.5 J/GH, depending on cooling and specific ASIC batch.

Cooling?
Ambient temperature.

any specifics? it has to be hot (>25C), cold (<18C) or in a specific range?

Measurements were done with Emerson 1600.
It offers (according to spec) minimal efficiency of 92% in our tested working points @25C ambient.

Is there anyway to cut the fan speed to less than 40?  I plan on under clocking and am interested in reducing noise.



It could be that these fans don't even start to spin up till they get a certain amount of voltage equivalent to 40 on the UI.

I don't run the coolest cold aisles in the world and I'm suprised at this last order of SP 20's hitting 1650 gh stable. Very content customer on this last round. The first batch I cannot get past 1545 GH. Watts fan everything at max. I even swapped placment with the new one to see if I have a bigger airflow problem then I already know is brewing up. But same results, just better Asics I suppose.

after seeing my results try under clock and under volt

I am using 747 watts to get 1380gh

I will run one from the October and one front this batch with your settings later tonight. Had to go to the regular job.

Is there anyway to cut the fan speed to less than 40?  I plan on under clocking and am interested in reducing noise.

edit /etc/mg_custom_rate via ssh

looks like this is a new file


miner-FL1444045011# ls mg* -1
mg_custom_mode
mg_custom_mode_sp20
mg_custom_mode_sp30
mg_disabled_asics
mg_disabled_asics_sp20
mg_disabled_asics_sp30
mg_generic_psu
mg_psu_limit
mg_try_12v_fix
mg_work_mode
miner-FL1444045011#

What is the format to include the 30% fan rate?



Even better you could just change the PHP file so that you don't have to keep manually editing  the mg_custom_mode_sp20 file...

Old code
Code:
<select name="FAN" id="fan_speed_select">
                                  <?php for($i 40$i 101$i += 10){
                                      
printf('<option value="%d" %s>%d</option>'
                                  
?>

                              </select>
New code
Code:
<select name="FAN" id="fan_speed_select">
                                  <?php for($i 30$i 101$i += 10){
                                      
printf('<option value="%d" %s>%d</option>'
                                  
?>

                              </select>

You can find this in /var/www/SP2x/settings.php around line 312 in Sp20 firmware version 2.5.27.. or you could probably just search the file for fan_speed_select.

My bad. Check mg_custom_mode. It's human readable.

Edit:
Just note that under very low fan settings you might stress the back side of the miner and it can cause termal shutdown.  Theoretically it should work since the system scales on both dc2dc and asic temperature. be careful when touching the back side of the miner - it can become very hot

My SP20 came with firmware v2.5.26 but I see there is a newer v2.5.27 - what does the update address & is it worth updating?

Peace  Smiley

PS: Excellent piece of kit these SP20's - well done SP-Tech.

Is the startup asic voltage also the minimum voltage for temperature scaling.. or can it go lower than that?

I have now set 1 sp20 and 1 antminer s-3  one 1 evga 1300 g2

pulling 1043 watts for the two units 426 gh for the s-3 and 1322 for the sp20   so 1043 watts gives me 1748 gh .

I was thinking 1152 watts and 1650-1700 gh using an evga 1600 p2

this is much better.

due to the constant overheating during noon hours since upgrading to 2.5.12 i have lowered max watts & max volts on my sp30.

the hash rate on the gui hardly changed but the pool shows a significant loss (500-700GH)

if im not mistaken, 2.5.12 was specifically tailored to the problem/s associated with near zero temps.

do you mean this set of numbers?


Temp Front / Back T,B
38 °C / [b/74,71 °C[/b]

if so what is low enough?

right now my room temps are very high due to 74f temps in Howell NJ USA

Hi All
We have now new support team.
You can see them online as spond.support.1 (Sonya) and spond.support.2 (Michael).
They accept direct Skype calls between 14:00-16:00 and 19:00-21:00 Israel time.


You can also send mail like always, to support@spondoolies-tech.com.

If they can not help, they will redirect you to me.


Well, got up early today to talk to support. It's 14:37 Jerusalem time, nobody there.

Now I gotta go to work.

I get off work too late to talk to them at 1900 hours...some I'm screwed for another week.



I feel your pain, they've been ignoring my emails for 3 days now. Customer support is non-existent.
What's your order# and support ticket# ?

Guy

I spoke with Michael I think really late Friday night. He said he was going to look into an RMA, or maybe a board replacement,  as he tapped into my SP20, and couldn't get the stuck ASIC #4 to work at all.

My SP20 arrived early November and the order # was 2754. I don't have a ticket support number.

Oh, thanks for the T-shirt, by the way.

Good price and good power consumption of SP20 - imho it's better then S4 and Prisma
Guys, do you plan to open cloud mining service or own hosting service? I had bad experience with one of you hosting-partners, so don't want to repeat a mistake. Shipping fees and electricity price make me sad Sad

it is way better then the prisma .  

  the best i got my prisma to do on under clock was 1000 watts and 1300gh  

 so far the  sp20 has done 747 watts and 1353gh on under clock  

if you do the underclock and set fan to 40 it is not as noisy as the prisma.
