Note that the hash rate is more expensive the higher you raise the watts.
You can get ~4TH for 2300W, but the next 600W will only provide 0.5Th - much more 'expensive' hash-rate in terms of power.
So I guess for 2500 the system will give about 4.2TH. If you pay 0.15$ per kWT, you still better running 4.5TH (100$ more). If you pay over 0.35c per kWT, you better run 4.2TH.

About $0.022/kWh here, once we get above 200 kW of usage. About $0.04/kWh before that. The SP30's efficiency doesn't enter into my configuration decision calculus yet. Risk of broken equipment does, but the chance of improving the performance of all 68 of our machines with some simple mods largely offsets that.


Thanks! I'll take a look.

Zvi, I'm expecting significant diurnal variations in ambient temperatures in our datacenter. Does minergate take ambient/intake temperature into account at all for determining optimal settings?

Perhaps it would be good to add an adjustable ambient temperature coefficient for some of the major variables, like the PSU power limit. If the thermal shutdown temperature for the PSU is 150°C (what is it actually? I have no idea), and ambient is 20°C, that would be a temperature gradient of 130°C for the PSU's waste heat to flow over. For the sake of easy calculations, let's say the PSU goes into thermal shutdown if you use settings that result in more than 130 W of waste heat being generated in the PSU. That would indicate that the PSU has a thermal resistance to ambient air of 1 W/°C. If you then dropped the ambient air down to 5°C, you would expect to hit thermal shutdown at 145 W instead; if ambient rose to 35°C, then you'd hit shutdown at 115 W. As I understand the limit finding algorithm, you'd end up running your PSU at settings which work in the worst-case scenario (115 W) even during the best-case scenario (145 W) if you saw high-amplitude temperature fluctuations.

Another option might be to first learn what settings work at one ambient temperature, then after that process has completed, create a few separate learning context variable sets (structs or whatever) for different temperature bins, using the original ambient temp settings as a template, and refine the new bins independently. This would probably be significantly harder than simple temperature coefficients.

What you saying about learning context is an option - but the SW does not work with learning context - not in voltage/freq scaling, and not in AC2DC scaling. In voltage/freq scaling I recalibrate every voltage change - because temperature difference can cause difference in results and there are too many contexts (voltage/heat)., and in AC2DC the user can set it to 1380W if he wants to recalibrate.

I don't want to restart system too often, it will cause too many questions without any real value (imo).

....And statements that assert that substandard performance at 110 volts is not a problem because customers can always host in a datacenter instead of running their machines in a home or office environment are disingenuous. ...
...

Adding a 240 volt circuit to most houses is trivial and cheap. If you can afford 4K for a mining device, you can afford another 50-200 dollars for a new circuit or, worst case, a new panel with a new circuit. I find this argument disengenuous.

I tend to agree.

I find this argument thoughtless. Those of us who don't own our own homes are often prohibited from making these kinds of modifications.

You can always suggest this improvement to the landlord. And if it keeps you there safe and happy, (s)he will invest easily in any electrical modifications improving your quality of life. Then it becomes an improvement at "no cost" to you!

Speaking for myself:


Now I live in europe where 240v is standard, but apparently even in the US/Canada you do actually have 220v just split in two parts and its a matter of getting a little y-cable and you can do it in a home also.  So buy the cable already, sure it cant cost more than $5 on ebay.



Europe has 220v single phase, usa has 240v split phase.  Not a simple cable to have 240v outlet in usa.  Minimum of a new breaker. Usually requires new breaker and new wire to new outlet.

usually the US/CANADA is wired with a Hot 120V, neutral (0V return), and Ground (0V safety). Changing the neutral wire for a select outlet to run on the secondary phase of 120V will give you 240V at the outlet and work with a 'typical' PC power cord.

however, running 240V in a 120V socket is against code, so it should be switched out to a 240V-speced outlet.

You are correct, It should be replaced.

yeah, or you could ask the landlord. As long as it is done correctly they probably wont care.  Or you could use your stove outlet (40-50amp 240v) or if you have a gas stove tell your landlord you want an electric stove and you will pay for the outlet to be installed. Keep the gas stove and use the juice.  same could go with a dryer.

If you can afford 4K for a mining device, you can afford another 50-200 dollars for a new circuit or, worst case, a new panel with a new circuit. I find this argument disengenuous. Calling out a company for missing their target is fine and dandy. From what I've seen, Spondoolies has acknowledged that they made some errors and are working to rectify it. But bitching about a circuit or two is just plain trolling. This is high school level stuff.
 

I agree, even if people don't know how to do it themselves, Electricians aren't that expensive, and surely they have a buddy that would do it for a few beers. Or maybe not. Still, couple hundred bucks isn't that much.

I don't think any situation would ever exist when a new panel is necessary.

To upgrade from an 100amp service to a 200 amp service where I live is 2500 bucks to install flat rate..low end which is a very easy switch in my case anyway I was told..
....all the electrician's in this area charge the same rate.....the city I am in requires that the local utility shut down service and also that the electrical inspector and an electrician ARE PRESENT and it is signed off by the Electrical Inspector before the power utility can turn the power back on..so essentially you are paying for the utility service the electrician and the electrical inspector to stand around...and pay them for the morning shot ..to get everyone there...

and yes I asked 4 Electrical contractors they were all within $100 usd of each other and also if ....say the elec inspector or electrician is not on site when this
is done..then you guessed it ..the utility company will not turn power back on....a big headache

will try to slip by with the 100amp..don't have house a/c nor forced air furnace nor major other drains on the elec panel ....so should be OK the panel and wiring
is modern....

but heat out of the basement is my current challenge oh...and again this is CITY rules....along with the State rules and I think just the local utility protecting
their butt cause everybody else is so anal about all this!

Searing


No a/c.  I feel bad for you.  Forced air furnace isn't really a big drain.  Electric water heater, electric dryer and electric heat(elec furnace or baseboard heat) are the big ones.  Unless you have a shit pile of miners you should be ok. 

Also if you are going to pay them to put a new panel in, may as well go with a 400amp.

Also if you have enough $$ worth of mining equipment to necessitate a dedicated 240v circuit, you probably should have had home ownership higher on your priority list.

Smiley This is a little pushy .. next time, if you're a miner, you should own a boat too, have 5 kids and live in a mansion, if one can find a good enough reason. Three years ago you'd find ONLY geeky guys with their GPUs/CPUs in the landscape. Now we jumped to data-center grade stuff, and I don't see the need to own a house yet just for "being a miner".

+1 Hoping Norway doesn't ding me too bad when they get shipped to the DC there. Fingers crossed.

I am hoping the compensation make for a shorter haul to breakeven land... come on BTC rise!

bitcoin never expected to be played with GPUs forever. the evolution to efficienct hardware and the creation of semi-centralized mining clusters was always a known eventuality and a healthy part of the growth. Its no different then when satoshi was mining 30% of all blocks at the beginning or when people had garages with 50+ GPUs running only a year or two back.

The SP30 design is ideal for this expansion, but you are right that mining profits are getting tighter recently. Before long a shift in bitcoin price will be required in order to offset the growing operation costs to produce a bitcoin

This remark isn't just thoughtless, its stupid.

The people who spend enough in equipment to need a dedicated 240v circuit are clearly investing.  They are taking risk on the equipment in hopes to turn a profit in one way or another.  Yet they rent a house.  The landlord is making more money in rent then he pays in mortgage and insurance(otherwise he wouldn't do it).  People are concerned with power availability to profit on btc mining, yet loosing their ass monthly on housing (likely by a significantly larger margin).

Please clarify how my comment was stupid.

Not quite the same. People need a place to live.  It makes sense to me to have a place to live in the most economical way.  People don't need a boat, kids or a mansion.

I agree that mining has become mostly centralized by the wealthy, but I am not rich at all.  You don't need to be rich to own your own house.
