Anybody know if they will discount the price on total order of 4 SP10 units?

Thanks

Thats strange, what clock speed were you running?

hey it works again,
I reduced dc2dc to 57 and power to 1170

Have you tried every form of restart?

my miner stopped hashing today

ASIC STATS is empty

DCR says

DC2DC DCR inductor flag loop 0 (0xD0) = -1
i2c write 0x71 = 0x2 error2
i2c write 0x72 = 0x0 error2

I specifically haven't because its 1) impossible to capture 2) impossible to comprehend with a video. Use a decibelometer to comapre other sounds you know

Could someone post a video/audio of SP10 running so that we could hear the noise level please.

thank you

christ. Im planning on installing it in its own location where noise isnt an issue, but if the answer had been less of a resounding LOUD I may have been able to dd it to my current collection of 16 S1 and a S2 unit (which are approaching the limits of noise i can handle)

Perfect analogy.
It is insanely loud.  Just like the data centers.

Louder. You'd probably need 40 S2s to match the noise pressure of a single SP10.

70+ dB on medium clock.
Much louder on High.

how loud is LOUD?

are we talking the volume of an S2? 4-6 S1 units? or is this vaccuum-cleaner loud?

Anyway to get the older version?  I was hoping to see around 1.4 TH.

I just got mine and slightly disappointed at the 1.32 TH/s in Turbo mode. (around 1.29 TH in Normal).  BTC Guild sees the hashrate slightly lower, of course.

I'm still pretty happy with the units, though.  They are easy to set up (though they started mining for Spondoolies as soon I plugged them in).  They are LOUD, even in normal mode!  I put it on turbo so I can get the extra speed.  26 C ambient temp.  They are in the basement - cooler and don't have to deal with the noise unless it's laundry day, lol.

So, any progress on getting the fans quieter (especially the PSU fan)?

EDIT: got new firmware - 1.3.49 - slightly faster.  Between 1.33 and 1.36 TH now.  Still LOUD!

QUIET MODE IN SP10 1.3.XX
Quiet mode setting for FW 1.3.XX:

Calibration and warm-up:

1) Goto WebUI settings tab -> "Advanced Voltage Settings"

2) Set fans:80%, start voltage:0.660, max voltage:0.740

3) Let the unit run for 30 minutes.

4) Goto "Asic Stats" page

5) Look at the column "vlt". It shows the optimal voltage found per each DC2DC by the SW in millivolts.

6) Remember the maximal (MAX) and minimal (MIN) values. Also look at the AC2DC power=XXXX[YYYY]. XXXX is current power, YYYY is the power limit.

 

Setting

1) Set the fan to 80%, start voltage to (MIN-10 millivolt) and max. voltage to MAX (note that this field is in volts, not in millivolts).

2) Now you can play with the max Voltage/start Voltage values based on the calibration values. The system will find optimal values within the range. Try steps of 10 or 20 millivolt and see the effect on the hash rate. Leave at least 30mv range between start and max. Do this on warm system (it should be warm after the 30 minute mining). Always compare the hash rate you are getting with the AC2DC power.

3) Once you choose your voltage range and you know the AC2DC power, set your fans. The goal is to have most ASICs in the ASICs page to be in the 77C range. Here is rule of thumb for ~24C rooms: 1250W=80% fans for good performance. If you set to 1000W, you can set to 50% and it should work. Just look at your ASIC page and make sure most ASICs are 77C = then you are not wasting energy on leakage. If most of them are hotter, ether decrease voltage, ether increase fans.

 

This way you can set the quiet mode you want that will match your temperature and your board.

 

P.S. We are adding option to control max PSU limit in FW 1.3.30. Default is 1250W, but it worked for us at 1265W - 1% more. You will be able to use that extra power in cold environment only, since in hot ambient the ASIC temperature will limit you. Also in first batch the DC2DC will prevent you from using so much power at 0.670 volt. But in May batch in 0.69v it will help.  !! If you set too much, your unit will shut-down and PSU led will start blinking, you will have to power cycle and change limit !!

 

P.S.S. Well, now you can also change the DC2DC max current from next version. The spec. says 60 Amper, we set upper limit at 61. I recommend not touching those. However, you can try setting them to 62 or 63 if you are in cold environment, and you have some spare power in AC2DC. Just monitor their temperature for the first hour - it's the DCt column in ASICs page. Should be under 90C (it has thermal shutdown around 120C). You will probably need it only if you purchased powerful PSU or some of your loops got broken, so you want to pull more from other loops.

Been renting several of these miners for the past couple of days.  They are amazing.  Very stable and produce 1.4GH.  Recommended if you are looking to take the next step.

TECHNICAL BLOG
1.49 ON EARLY MAY BATCH UNIT
I created new FW version that has option to customise DC2DC current (1.3.31-experiment).
If you have COLD ambient temperature (<25C) and slow corner May batch unit:
Set
-----
DC2DC current limit to 63
AC2DC limit to 1265
start voltage to 0.68
max voltage to 0.73
fans to 80%
------
and you just might get almost ~1.5TH in miner, which is about 1.48TH in pool.

If you don't have slow corner May unit or don't know what Asic corner unit you have, set start voltage to 0.660. I didn't try it but it might give you a bit more.

Just monitor the DCt column in the ASIC stats that it is not over 90, and I don't know how stable it is, so if you leave it over night you might loose hash rate if it falls.

It's in custom FW downloads, 1.3.31-experiment, only for the brave for now.

Updated styling.

it's a tad noisy (but I can put up with that, for this...)
ramped in (after 12 hours on full power draw - my most recent purchase (SP10 batch 2)
not too shabby!


and 1.49TH/s in the UI;

There is a chance I'm incorrect, but I believe the fan can be controlled directly by adjusting the numeric value in the file

/sys/devices/ocp.3/pwm_test_P9_31.12/duty

cat that. the formula seems to be 12000 + (%% * 200)

for max fan at 100%

echo 32000 > /sys/devices/ocp.3/pwm_test_P9_31.12/duty

for fans at 50%

echo 22000 > /sys/devices/ocp.3/pwm_test_P9_31.12/duty

personally, I would not go less than this. but if you must, feel free to plug in whatever value you want and have at it. watch your asic screen though, if you start getting too many 119C (they show up as red), then they will downclock and you will lose hashing power.

Glad to hear that was sorted out!

Thanks for the suggestion about the fans speed, we will look into it.
Please feel free to submit further improvements suggestions and feature requests to [email protected].

Thanks, i lied.... i touched it again this morning.....

I use recorvery SD method that Zvi told me. There are 2 methods to revert: replacing uImage file, or recovery SD.

The recovery SD method worked like a charm. Performance (1.2.7) : 1.38TH/s @ 1250w at the wall.

I cant wait for the 240v wiring now...

Thanks Spondoolies team

PS. would it be possible to have an option to adjust fan speed manually? or use temp as target setting (performance is auto adjusted to stay on or below certain temp) ?
