...
Gone from 1.3x to 1.5x 1.665TH and climbing now, back temperatures gone from 37 to 67°C 77°C!

Keep your room cozy and warm in the winter ...

I am going to have to do something about the fan though, this thing is loud! Louder than all my other miners combined.

If I can't do anything about it I'll have to sell it I think

This is the fan used in the SP20.. beast of a thing!

Damn, fan uses a 4pin PWM Graphics card type header. Going to have to get one of these if I want to try other fan types:

PWM Fan Adapter for VGA Cooler Fan

Don't buy this adapter its a different fitting on the SP20

Good news is that it runs without anything plugged into the header so I'm testing another solution

wow so I got my SP 30 and the boards fell on top of each other ! don't know if it was in shipping or whenever I have a bad feeling this thing is DOA

I guess now I have to take it apart and restack the boards I'll post more pics in a few

I had the same problem with one of mine as well and after disassembly, I found a chunk had been taken out of one of the VRMs.

I'll post pic's as well.

Anybody with a SP31 found a 'sweet spot', can't get more than 4.7THs out of mine.

Anyone with SP31 getting more than 4.7Th/s?

... There is also a chance that the SP31 performs like SP30 should have at ~6.6TH but I'd guess it's more likely it ends up closer to 4.5TH ...

Our commitment and guarantee is for 5.5 TH/s +- 5% with 3KW at the wall.

ouch !
I was a bit luckier , no actual damage to the boards despite the cracked corner.  The SP20 is a cute and sexy little machine but it definitly not worth
$1300 (with shipping)  Best hash rate I think at 110V (assuming you have great cooling)  

Looks like maybe 1.8 TH max at close to 300 watts per power slot.  

right now at 24c front and 79c and 80c  back it hashes around 1650 TH max while pulling over 1200 watts

(it actually spiked at one point and blew out my power meeter and maybe one of my PSU's , good thing i have spares)

maybe it does a bit more at 240V i have some ic14 to ic13 cables comming early next week and ill try them on a dedicated PDU and see what happens

are you on 240 V ? what are your temps like.  Even the SP30 looses close to 200TH it seems per 10deg temp rise

I also have a SP31 that won't give more than 4.7Th/s. I am beginning to think this is the maximum, a far cry from the advertised 5.5Th/s.
My unit is running @ 240v and close to 3Kw.

While it was advertised for 5.5Th/s I think you missed Guy's update:

•    The hash rate of the SP31 will be 4.9TH/s +- 5%. Power consumption will remain the same 3kW at the wall as in the previous SP30.

[jtoomim]

Anyone with SP31 getting more than 4.7Th/s?

We have 13 SP31s here at Toomim Bros Bitcoin Mining Concern right now. With 16C intake temps, we're currently seeing the lowest performer getting 4743 GH/s, highest 4915 GH/s, mean 4835 GH/s.

Do this from the ssh console:

Code:

echo "1' > /etc/mg_ignore_110_fcc

http://www.spondoolies-tech.com/blogs/technical-blog

If you have a lot of machines to configure, you can also scp it over. Example if your machines are 192.168.1.5 through 192.168.1.8:

Code:

echo "1" > mg_ignore_110_fcc
for ip in 5 6 7 8; do scp mg_ignore_110_fcc root@192.168.1.$ip; echo "Finished 192.168.1.$ip"; done

You will then want to change the power limit on the PSUs. In my experience, Murata PSUs can handle between 1330W and 1380W when run off of 235-245V in ambient temps no greater than 22C. Keep in mind that when Muratas hit their power limit, they sometimes lock up and need a power cycle to recover them, so you shouldn't increase the limits unless you're going to be nearby for several hours.

I also recommend using starting voltages of 650 mV or 645 mV with SP31s, not the default 655 mV, since 655 is too close to the settled voltage for some SP31s. You may want to change the fan speeds as well. I'm not sure yet what the optimum is, but I suspect it's the setting that will eliminate thermal throttling on the loop 4 and 9 ASICs, but no higher.

[VeritasSapere]

I have a question. would it be possible to put say 3xSP31 inside of one of these:

http://www.acoustiproducts.com/en/ucoustic_active.asp

I would have the ducting setup aswell so that i can vent the hot air out of the building, i am also in a cold climate. I am sure that there must be many people here intrested in making it easier living with these machines.

Yes, this has been done with 2-3 spondoolies

Thankyou 

[jtoomim]

what are your temps like.  Even the SP30 looses close to 200TH it seems per 10deg temp rise

I've measured it at about 10 GH/s per 1C for SP30s, or around half what you indicate. I've measured this by taking a machine out of our racks (on around 14C air, IIRC) and sticking it into the coldest spot of our hot aisle (about 26C at the time, IIRC), and seeing about 120 GH/s drop in the hashrate. My memory is a little fuzzy on the exact numbers we got from that experiment, but it's accurate to +/- 20%. I've also done other measurements by looking at diurnal variation in performance on SP30s with similar results.

SP10s are much more sensitive to temperature. They also vary in performance by about 10 GH/s per 1C, despite having less than 1/3 the total hashrate.

I've heard that SP20s are more sensitive to temperature than SP30s, but I don't have any here to test.

Preliminary observations with SP31s (as well as predictions based on what I know of semiconductor physics) suggest that they're more temperature sensitive than the SP30s, but I haven't done any systematic measurements yet.

That update means fuck all after the fact, Guy once again overstated and under delivered. Was it another slow corner batch this time? Such an arrogant bunch ...

Man you spend too much time in your DC 

[zvisha]

If you are having weird behavior in SP3x : upgrade to 2.4.9 2.5.9. If all works well - don't.
Good day.

Don't upgrade to 2.5.7 and beyond. Stay on 2.5.6 till the end of weekend at least - it is the last of the 2.5.x series.
Once I will release 2.6.X - upgrade to it only.

[jtoomim]

If you are having weird behavior in SP3x : upgrade to 2.4.9. If all works well - don't.
Good day.

I take it you mean 2.5.9.

Confirmed: 2.5.9 is available

You may want to change the fan speeds as well. I'm not sure yet what the optimum is...

I did a little experiment with SP30s. I took 10 machines, and gave the even-numbered ones a fan speed setting of 80 to start with, and the odd numbered ones a fan speed of 70. I then waited an hour, and recorded their temperatures and performance (from monitor.php). I then switched them up (odd 80, even 70), waited another hour, and recorded again. Here's the result:

That's 4578.346 GH/s at 80, and 4578.2495 GH/s at 70.

Conclusion: if your intake temps are around 16C, and you're using September SP30s, fan speeds around 70 or 80 seem to be equally good.

Some SP20 Pr0n

[samsonn25]

After the fire in Thailand on the mining farm.

How can they make up this fictitious amount for 100 Spoondolies?

Spondoolies-Tech confirmed that much of the hardware used in the facility was sourced from them.

The manufacturer's CEO, Guy Corem, told CoinDesk that he had visited the site in late June, when it was primarily populated by about 1,000 Dragon miners and around 100 Spondoolies-Tech miners.

Corem said the facility was expanded shortly after his visit, with hundreds of Spondoolies-Tech SP30 miners. These had operated for more than two months without incident and technical data indicates they were cooled properly, he added.

'Kosher' operation

There has been no official word on the extent of damage suffered by the facility. It is estimated that the farm housed upwards of 2,000 miners when it was destroyed, including about $2m-worth from Spondoolies-Tech alone.

100 sp30 at 2 million is 20k each.  Someone is sharpening the pencil in accounting.

Pay attention to timing please. There were no SP30 in June. Those are SP10 miners...
