- sum of PSU(unknown) input watts in addition to DC2DC watts, either on ASIC Stats page or main page, as for estimate of power at wall or PSU efficiency <- will implement in 2.6.7. For sp20 I assume 90% efficiency

I think you misunderstood me:
the low voltage DC2DC watts are way below (80%) the watts at the PCIE connector inputs in SP20. And the efficiency between the PCIE and the wall is determined by the PSU and should be around 90%.

I mean summing up these 4 values underlined:


-----BOARD-0-----
PSU[UNKNOWN]: 0->(162w/162w)[162 162 162] (->162w[162 162 162]) (lim=288) 0c 306GH cooling:0/0x0
-----BOARD-1-----
PSU[UNKNOWN]: 0->(152w/152w)[152 152 152] (->152w[152 152 152]) (lim=288) 0c 289GH cooling:0/0x0
-----BOARD-2-----
PSU[UNKNOWN]: 0->(176w/176w)[176 176 169] (->176w[176 176 169]) (lim=288) 0c 326GH cooling:0/0x0
-----BOARD-3-----
PSU[UNKNOWN]: 0->(171w/171w)[171 171 171] (->171w[171 171 171]) (lim=288) 0c 320GH cooling:0/0x0



multiplied by PSU eta they are pretty close to the actual consumption at the wall.

may be also a nice point to watch on next generation miners to optimize that 20% loss of the dc2dc units.

Did someone tune up the spondoolies hosted miners?

http://eligius.st/~wizkid057/newstats/userstats.php/1Adam3usQMbQWScA5AXnnDsRMeZeCh6ovu

my 4x sp10 hashrate jumped from ~6TH to ~ 7.5TH?  (Which'd be a very nice hashrate at 1.85 TH/sp10 vs 1.4-1.5TH advertised).

Maybe someone accidentally configured another one for my payout address during a reshuffle or config change?

Adam

We disconnected the SP10s and replaced with fixed RMA SP3x
More efficient.

now with fan control:

did anyone succeed to find an adapter for the fan to fit in the very tiny 1,5mm contact spacing (it fits NOT that small 2mm VGA fan connector) of the controller board?
BTW: AFAIK these 1,5mm plugs are specified up to 1 amp, the stock fan uses twice!

2.6.7 available in Spondoolies app-store for free 30 day trial Smiley

I feel like this is a dumb question, but can you point me in the direction of the latest firmware?  I dug around in my account to no avail.

Cheers.

Firmware upgrade in web gui
choose "Manual(ly)"
choose 2.6.7-TEST out of the pull down menu-revealed by clicking on little up and down asterisks (initially only 2.5.12 is visible)

Awesome, thanks!

Will be available in advanced settings from 2.6.7

is this thread also the right place to put in some feedback or bugs?!

I experience some failes to display the working pools from cgminer in the main Page. This appears randomly after some hours, but cgminer is working fine with connections to these pools?! May belong to the API-Allow problems I had with allowing Subnets and that strange backslash?

Next bug is that one sp20 is probably rebooting at least twice after a power of so that it needs at least 5 Minutes to be ready to mine.
will try to save the logs next time.

If you want to replace fans-I finally opened one SP20 and I don't see how I can disconnect the stock fan from the board connector unless using some bend tweezers. the connector is upside down and not easily accessible.
Are the sides even removable?  The sides they have these round hole screws-are those removable as well?

I have a situation where at fan 20 almost all are at 85C, but one is stubbornly at 100. since it goes by a single chip with the highest temp, i wonder what my fan setting would be. If close to where it started, then it is not even worth doing. Instead, i can just pick 10, then modify voltage until the "worst" chip is at 115. In any case, it is a very cool feature.

Thanks to the auto fan i was able to bump it up 0.64/0.65 settings and stay under the 20% fan it used to be. The heat is a bit more, but at least the noise in my office is WAY down with 3 of them with a bump in speed  Grin

Not everything goes smoothly with auto. On one machine, loop 3 gets temporarily disabled (upper image). cause? once i switched from auto to fan 10, everything is back to normal (lower image). on the second machine this did not happen, so maybe it is sporadic.

Does the fan RPM show in the output from cgminer now?

Can I set it/can it go below 20% now w/o a SSH hack?

Thanks.

M

You can see real fan speed in ASIC stats, it's a bit complicated to move it to front page - I will need to dump it to separate file from minergate and I am too lazy for that.
Yes, you can set it to 10% or to AUTO that can take it down even to 6% if no ASIC reaches 120C.

Regards`

Would you be able to put the fan speed in the API output please, ideally in both cgminer and /monitor.php?

Thanks.

put out the 4 screws from the controller board to unconnect the fan.

Two underclocked SP20 report 681+682 watts=1363 watts at the wall, but kill-a watt reports 1424-1425w for the same two (nothing else is connected to kill-a-watt).
SP20, i assume, should be able to measure precisely. Can kill-a-watt be so much off or Sp20 showing 'theoretical" at the wall assuming gold/platinum PSU, hence a difference because I use CX750M bronze?
EDIT: OP posted that it is basically "theoretical" at the wall, assuming 90% efficiency. Increase by at least 5% if you use Corsair CX750/CX750M bronze. In my case 2.6.7 shows ~680w "at wall" while it is actually ~712.5W.

Prices are great these days but I must say it's a bit sour that I could have basically not bought an SP30 at all back in august and bought it instead today, and I would have saved money overall. In other words the miner prices have fallen faster than the revenue.

You did not!!
my error!!!  Shocked Roll Eyes
I only saw new name DC-W which I confused with w=wall (which by the way makes no sense as it is AC at the wall).
you new entry "wall watts" matches my PSU and measuring very well!!  (y)!

What temperature should I aim for to prevent harming the SP20?
I am reaching 78C on Back T,B with 23C intake.
Also does anyone have a calculator or chart showing effeciency ?
Clocking it down to around 1050GH gets me around 0.51 watt per GH.

So besides noise & heat, does it really pay to underclock vs. stock on the SP20?  I tried to run the numbers allowing a total of 4200 watts at the units (not wall).  I used 700w for underclock at 1200gh/s and 1200w for 1600gh/s.  My calc shows about $697 higher price for 6 underclocked units vs. 4 stock units.  The underclocked higher hashrate would take over 600 days to return the higher price of underclocking.

Am I missing something?

Take a look at your chip temps.  They are more important than the temp of the air leaving the machine.
