Otherwise, i'm afraid bitcoin mining will be concentrated in China.

I believe that this will not happen. Time will tell.

I was just told by a Chines friend that the bitcoin mining community in China is alot bigger than i thought. In April when we got Dragon miners at $3-3.5k each, the same miner was being sold for $2k + 15% off for bulk orders. They're sold alot more domestically, including Bitmain.

While they dont have mega datacenter, their combined hashrate is probably the largest.

ONLY miner manufacturers that are not Chinese: SP and KNC, that means something doesn it?

Nice SP20 case. Pity there's no PSU inside.
All those cables might look nice in the pictures, but they're ugly when shelved.

What about BitFury? KnC? CoinTerra?

I see it as being much cleaner than other miners which I will not name.

Why would anyone want to preorder an SP35 for end of November delivery when Spondoolies is expecting to release their gen3 in December at 0.1 w/gh + $0.2/gh? (and no preorders)

thanks that was refreshing I could use some 'good news' at least in the sense someone is 'striving' to fight the good fight at least

(now back to my dismal price watching slow drip downwards....sigh I need a different hobby!)

Quick question for Ziv,

Does the firmware use Intake/Exhaust temp to tune the chips at all?

For example, the ASIC stats show chips temp at stable 77c (or below). But the exhaust temp is higher than that...80c... does the firmware use this to throttle the chips?


EDIT: btw can you add an option to be able to disable each chip? I just figured out how to get below 0.65w/GHs but the hashrate is dropping in/out due to some chips die/come back. I will post back the result to show others how.

I'd really appreciate this help.

I guess you are talking about SP10.
We don't measure all temperature in ASICs, just the high ones. Under 77 actually means under 105 or so.

Regarding option to disable each ASIC, it can be done, but not trivial and I do not have time to do that at the moment.
You can add such functionality and create a pull request.

Share you method. Have you lowered the voltage or limited the PSU max power? If it's either of the methods have you tried the other one?

Its involved alot of work so i spent basically all this weekend. Its not done as i need a software solution to disable some chips. I really hope Zvisha can update firmware to tune them better( downclock or disable chips with high temp)

First, i removed all the 6 tiny fans, these are like 8watt each (the loudest fans i've ever heard). Stacking all the miners with some pink foam as spacer i use Nidec 120mmx38mm fans at the back (0.8A) for a total of 9 fans for 8 SP10s. For anyone with just 1 SP10, you can get away with only 2x120 Nidec fans . These are server fans, not your consumer cooling fans. They're strong yet not as high-pitched loud.  

I actually removed all the tiny fans when i collocated the SP10s with special ducting work, so i already got this step done. Since i now gonna host them in at my office closet, i use the 120mm fans


Second, my setting is :

Fan: 40% ( the minimum setting by default but i feel this does not control PSU fans as i thought, zvi, can we control the PSU fan?)
start voltage: 0.585v
Max voltage: 0.595v

Max power consumption: 700w.


All this got me: 600-640w at 920GHs-1000GHs.

BUT i'm gonna see if i can physically KILL some chips as i dont have a software option. Reason you need to do this is because some chips will get way too hot and they throttles the whole miner. Since you removed the tiny fans, some chips will get alot hotter due to not having balanced air flow. Thats ok. I actually find having chips completely disable yield a better w/GHs. Only let the coolest chips work at their best efficiency is the way to go.

I also have another idea, but i dont have time to play. I'm sure it will work even better based on my calculation:

Remove all the boards ( i dont know if we can remove the mainboard from the controller, can SP confirm this? are they soldered together? they're looked like the pins are very strong)

Get a small fish tank and dump them in mineral oils. you have to space all the motherboard tightly together with no gap. Its required for flow balancing.

Use a centrifugal drive pump, inlet and outlet from each end and a alu car radiator.

You got the idea...etc

- SP20 and SP31 will be shipped next week
- Spec update early next week, I'm waiting for SP35 build and test.

Machines are on their way this week, Sponds always leaves it till the last few days, that is their way, but always deliver.

one my psu is dead (the guy who power cycle the rig said that the PSU threw spark out of the fan  Grin) There is no more support for this SP-10 now.
Can SP-T tell me what's the PSU model I shall buy ?
Can you send a fresh new one ?

Btw, any news about the compensation plan ? i have no news since last week....

Yeah, I am getting the run around on compensation also, got told my wire directions were rejected/incomplete even though I had my bank fill out the questioner. September batch didn't go online until October 1, no web interface for hosted unit (need to email support for pool change). spotty CS (they may or may not reply depending on the day), all in all not a happy customer.
