Just out of curiosity: Has anybody ever reached the 1.7 TH/s?

Sure.

About 16 of 22.

But only until I was able to cool down the intake air to 17 C.

But after a while it slowly decreasing.

Now what started at 1710 runs about 1650-1640.

A restart helps out, but have to do it day by day.

What I can tell you, a stable 1640-50 is the average.

yeah I played around a lot with my 4 sp20's

I can do 1400gh easy with really good watt to gh  low noise and decent heat
 so 4 x 1400 = 5.6th at about 3200 watts  0.57 watts a gh

Low noise at these settings means what in dB? You probably posted it already, but I missed it.

never found my db meter.  but at fans 40 or 50 settings the  db is under 60.

Yep.

I don't care about the noise or something.

Just shot up the fans for 100.

Second question: anybody care to post the exact box size and weight for SP20, please?

Hi Guys,

Can anyone help me out. 

When I run the "Devs" command on an SP30 miner (running most current firmware) I get the following output.
av=4445838.29,MHS
5s=5923594.28,MHS
1m=5187361.37,MHS
5m=4678246.84,MHS
15m=4526365.21

I notice that the av number seems to be the only number that is accurate.  Can anyone tell me what the other number are?  I would like to know why the 5s shows almost 6TH/s in this example.

Thanks guys.

Statistics 101?... That aside

As the measure time interval decreases variance increases e.g. A 5 second average reading has much higher chance to vary above and below the expected value than a 5 minute window.

This is in part due to the manner in which the mining software calculates hashrate.

A personal example. I have a particular miner which consistently performs at 500Gh/s both in cgminer avg and pool but I e observed the 5s avg vary from 200G to 1T

Ok So my real question is, does av show the current (live) hash rate? 

I use http://www.multiminerapp.com/ to monitor the SP30's and it generally works great.  The one problem is that it consistently reports the miners hash far to high (between 5 - 9 THs).

The software polls the miner via the CGMiner api with the DEVS command to get the stats.  I am trying to ascertain what in the returned data is the live hashing speed so that I can get the devs to ensure that is what is being recorded by there software.

I hope that makes sense.  Thanks again guys

They learn to loose rate overtime but usually not more then 50G.
I guess you can set your starting voltages to your runtime voltages and add daily restart in cron.
The voltage scaling works well enough for me not to mess with it.

And guys - be very careful with testing versions.  They were not fully tested I upload them for our testing purposes or specific clients that need specific functionality.
Not recommended.

It works fine, please don't misunderstood me.

I'll didn't had enogh time to play with them, just set the voltages, watts, fan to 100 and fired them up.

I will have time for tweaking at the weekend, I'll share what I've got.

One of the test firmwares work the best for me. I can't remember wich firmware was the original, maybe 2.5.6 or something.

I had problem with loops turning off.

I've installed 5.33 test then the problem gone away.

Don't bite me if I wrote something wrong I didn't really had time to go in the depth of these machines, these are my first impressions.

Thank you dogie. Nice topic number 
Great pictures !

yup, all day long. i just cranked the voltage up in increments 'til it hit 1.7.
again, Scottish temperature.

Second question: anybody care to post the exact box size and weight for SP20, please?

Dogie just answered that ... and a lot more ... The shipped weight of an SP20 is 6.1kg, dimensions of the shipping box are 235 x 240 x 495mm. An unpacked SP20 weighs 5.0kg and measures 130 x 148 x 395mm.

Nice review, as always Dogie.

Does anyone have any stats on how loud a SP31 is at high, medium, and low settings?

I'm considering getting a SP35, but SP10s were a bit too loud for my taste, so I'm hoping a SP31 / SP35 will be easier on the ears due to the larger fans.

I don't even mind running it at a lower speed if the sound is more bearable.

Thanks for pointing it out and thanks to dogie for info and nice pictures.
For those NOT on a metric system it comes down to ~13.717 lb and 9.25in X 9.45in X 19.5in for the full package and 5.12in X 5.83in X15.6in for the machine alone.

apparently, you can downclock it as well, but it is less clear.

SP50 announcement date?

SP50 announcement date?

sssssshhhhhhh 

[Hunger]

SP50 announcement date?

sssssshhhhhhh 

LOL spk50 already, seems its a bad mistake to purchase mining rig afterall


philipma1957: let me know if you want to get extra units, have couple that i havent use, and problaby will never

he's winding you up. my guess is it'll not be 'til next summer, at least.

[pak13]

Perhaps for the generation after but the stats for the sp50 show 28nm 12th 6kw, so current gen with power savings. Hence assuming it shouldn't be too far away.
