Hello,

Can someone please tell me what is exact wattage at the wall (in Europe) using branded PSU, without any overclocking? And what is exact hashrate of the device (average) on panel and on mining pool?
I would like to add Antminer S3 to my small chart, showing efficiency of various ASIC miners. Thank you!

10 amp x 240 volt = 2400 watt

that is the standard in scandinavia..

Do you have multimeter and checked it? What's device hashrate?

Yeah but having your miner queue work from 5minutes ago and gain nothing is also a waste.
Properly setting up a queue/scan-time/expiry can decrease the load of your unit and increase efficiency of the work done.
Proper settings isn't the dark age, it's just something that never is done right Tongue

There is a reason these options are here for us to optimize with the specific hardware we use!

I wrote the software, I know what I'm talking about. You're barking up the wrong tree with scan time and expiry.

I'm not barking up any tree
You wrote a software and we use the optimal settings for the different hardware and pools we use. Correct?

queue of 4096 is not helping the S3 while a lower queue is, so I'm sorry if you misunderstood my post.

Should we just go put 99999 on all the settings and expect them to function the same? Tongue

Here is the thing.
Queue is the number of work units to have ready in advance of need. 4k is high. 0 means everytime something runs out of work the CPU right then has to make new work. Having a queue of 1 means it sends work then makes one more.
Expiry is the time in seconds to hold delayed or un submitted work. 1 second means if it can't send immediately it's thrown away.
Scan time is the time that it can work off of given work units. Using stratum you will not need this lower as there is plenty of local work.
P2pool is different some. But for anyone not using it the defaults for cgminer are fine. It doesn't waste tons of bandwidth trying a new unit every second or throwing away work on any network delay. The queue is far above the default of 1.

Based on the figures thown about on here, I gather that tweaking the S3 to achieve 500 GH/s increases the overall at-the-wall wattage by 32% with only a 14% increase in hash rate. This 14% hash rate gain by itself also consumes more than twice the energy at 1.83 W/GH/s (2.38x more compared to the stock .77 W/GH/s). Is it worth it? Are we getting too carried away with tweaking and modding? How do these figures affect ROI? I can't help thinking that this is getting to be about interweb bragging rights on whose S3 achieves 0.5 TH/s.

Perhaps there are some hardcore mathematician/statistician among us that could elaborate on this subject.

It's actually ~20% power increase. Grin

Calculating ROI off one unit is just silly.
Look at the difficulty increase from 16.8 to 18.7 in past two weeks. It will continue to get worse. Every week-two weeks your ROI is going to get extended and extended.

If you pay for power or if you don't is the biggest factor in terms of ROI. Either way the small increase of hashrate at the current difficulty should give you multiples more of profit than it is a "power cost"

I'm not sure if you meant hash (rate) power or power consumed but I can't figure out where your 20% comes from. I figure:

500GH/s - 440GH/s = 60GH/s
Therefore: 60GH/s / 440GH/s x 100 = 13.64% (rounded up to 14% increase in hash rate from stock 440GH/s)

450W - 340W = 110W
Therefore: 110W / 340W x 100 = 32.35% (rounded down to 32% increase in power consumption from stock 340W)

I don't think calculating off the most basic unit (a single S3) and extrapolating from it is silly. In fact, it is a very sound method.

I agree that there is an advantage in OC'ing the S3 to a certain extent (depending on kWh rate) as the overall increase in power consumption is not that bad at 500GH/s (from 0.77 W/GH/s to 0.90 W/GH/s).

I put a six gauge wire on a 70 amp circuit breaker, from my main 200 amp fuse box to a spare room, how many s3's will I be able to run on that circuit, air conditioner is on a separate 20 amp breaker.

thanks in advance

70amp double pole? You can pull 56 constant amps through each wire at 120V each.

You could run about 34-36 S3's off that depending on how good your PSU's are.

It will get warm.

Stop right now. Call an electrician and get him/her to install a sub panel, tell the electrician your power needs. Do this before you burn your house down and void your insurance

edit: get permits and have it all inspected

in New Jersey, USA

you don't need an electrician if you own the home and you live in it. You do need a permit and an inspection.

Thats true in most US and Canadian jurasdictions. Still Call an electrician

It was installed by an electrician, and he did put in a sub-panel, I just need my batch 3 s3's to get here.

You guys also need to take account that your s3 would last shorter if you overclock

Yes but on which basis? Degradation due to voltages? temperature of the chips? There is a higher chance of electric costs being more than the mining profits on these units for many before they die.
If the quality of these units are decent, hopefully they will last long like the heavily overclocked S1's floating out there.

yes, I see no real danger of a unit "lasting shorter", as it might influence the asic life cycle by around 20% adversely, but normal asics last 5 years easily.

Seeing as they shouldn´t be able to generate more than electricity cost in 1-2 years (conservative estimate), this really is nothing to worry about.

It gives those of us with cheaper power or such more options for more hashrate now, and then it can always be dropped back down when diff etc rises

That's a very valid point. Anyway, the overall power consumption is really not that bad at 500 GH/s which is around 0.9 W/GH/s (I just figured this out just now).

I should also add that with underpowered CPUs that are always overloaded, using a pool with a large coinbase unfortunately will make things worse and increase the CPU usage further. "Generation" coinbases where your coins are generated instead of sent to you (such as those used by Eligius and p2pool) are two examples. That doesn't preclude them from being used, but it's worth experimenting to see if it matters.

Understood, thank you.

sir, ghash vs eligius vs p2pool
pls try these pools with the modified queue and scantime...

hope we can see something WOW here

Yeah if you need, just modify your own config, point them at the two pools and conduct your own tests Grin

My discarded practically disappeared and my load times were dropped by 1/3 1/2... I am happy enough with this. I can't justify why the same overclock is higher now and why the hashrate more stable

Please, what would you suggest we set the queue, scan time and expiry to?

Again, do not touch scan time and expiry.
Giving you generic advice regarding the queue setting is difficult because this is not my driver...I'd be surprised if it really needs to be that high though, and on a low powered system there is rarely anything to gain from anything even in the hundreds, let alone thousands.

Thanks for this. Going to run one of my units with --queue 32 overnight and see how the stats look when I wake up.
