Here's what pisses me off:

Bitmain says the following regarding their S4, "Power line not included. You may look for one line with no less than 16A in your local market."

Well, I've searched the WORLD WIDE WEB for a C14 Power cord and cannot find one rated higher than 15 amps.

WTF?


Pretty sure they made a typo and meant 16Awg. If you're running on 240v you need an 18AWG cord, ND if you're running 120v use a 14AWG cord.

I bought this one:

  Amazon.com: Tripp Lite Heavy Duty Power Cord, 16A,14AWG (NEMA 5-15P to IEC-320-C15) 8-ft.(P019-008): Electronics
  http://www.amazon.com/gp/product/B0091F8GP6/#

It's a replacement for a heavy duty server room style UPS.  When i got it, the packing slip said 16A but the packaging the cord was in said 15A.  Anyway until I received that my S4 ran fine for 2 days with a standard el-cheap-o 10A PC power cord that I had laying around in a box in my closet, so I wouldn't stress about it.



I have seen the one you purchased on Amazon.  It is a kettle cord.  A C-15 made to fit a C-16 connector.  It is used for higher amperage appliances.  It also has a valley in the C16 connect which does not allow a C-13 cord to plug into it.  However, a C-15 or C1-3 cord can plug into a C-14 connect.  The S4 has a C-14 connect.  I'm just going to purchase Trip-Lite 14 AWG C13 10 feet cord for the S4.  Uses the same gauge wire as the Trip-Lite C-15 8 feet cord you purchased from Amazon.

Thanks for your description.

David

Something else yall need to remember is the length of the cord.  A 10 ft cord will get hotter and pull more amps than a 3 foot cord.  All my miner power cables are 3 ft or less with an iso bar behind them.

JT

Actually given the same load attached to a cable, the longer the cable, the more the resistance, the greater the voltage drop across the cable (lost as heat), but the current drops. Since current drops, an infinitely long cable would have all the voltage drop but no current and would be cool.
No, current doesn't drop unless you're hooked up to a resistor. A power supply is (close to) a constant power device, so current will increase in proportion to the voltage drop. It will be pretty minor though.

Cable heating won't really change, since while you'll have 3.3x the voltage drop with a 10ft vs 3ft cable and essentially the same current and will therefore dissipate 3.3x more power, the cable also has 3.3x more surface area to dissipate heat. That's why wire gauges are rated for a certain current without regard for length.

You're wrong! Current will drop regardless of load if cable is long enough. The wire itself becomes a big resistor. Even if the supply was ideal, there would be little current getting to the load (or going through the cable) if the cable was long enough. Cable resistance approaches infinity as length increases. Of course, the difference between 3 to 10 feet is insignificant.

Hot time, summer in the city, back of my mine getting hot & gritty!!!

No, I am not. Current will rise as cable length rises and voltage at the load will decrease until either the input current or input voltage protection of the PSU trips at which point the PSU will shut down and current will go to (almost) 0.
For an S4 pulling 1400W (with a PF=1) from a 240V line and assuming the PSU trips off at 100V, you'd be pulling 14A and could thus use up to a 600m long 14 gauge cable. IE, preposterously long.

All i know is i had a heavy gauge 10ft cable on 3 avalons and the ends were getting reallllly hot.  Changed over to a heavy gauge 3ft cable and no problems.

No, current doesn't drop unless you're hooked up to a resistor. A power supply is (close to) a constant power device, so current will increase in proportion to the voltage drop. It will be pretty minor though.

The sole job of resistance is to oppose current [DC or AC].  Also, resistance will not drop (consume; eat) any voltage unless current is flowing through it.  Being that AC will flow ON or THROUGH a capacitor no matter if the capacitor is open (normal) or shorted (abnormal); voltage is dropped by the resistance in the metal plates of the capacitor (line cord).  However, I will not continue in the "science" of electrons flowing on/through a capacitor.  I will simply provide a table below for current ratings in wire other than magnet wire.

Current Ratings:

Most current ratings for wires (except magnet wires) are based on permissible voltage drop, not temperature rise. For example, 0.5 mm^2 wire is rated at 3A in some applications but will carry over 8 A in free air without overheating. You will find tables of permitted maximum current in national electrical codes, but these are based on voltage drop (not the heating which is no problem in the current rating those codes give).  Which I say again, "the wire gauge (AWG) used is more important than the length [when looking at power cords for peripherals].

Here is a small current and AWG table taken from the Amateur Radio Relay Handbook, 1985.

AWG  dia mils     circ mils     open air A      cable Amp       ft/lb bare     ohms/1000'
        
10     101.9         10380           55                  33               31.82           1.018
12       80.8          6530           41                   23               50.59           1.619
14       64.1          4107           32                   17               80.44           2.575

Mils are .001". "open air A" is a continuous rating for a single conductor with insulation in open air. "cable amp" is for in multiple conductor cables. Disregard the amperage ratings for household use.

To calculate voltage drop, plug in the values: V = DIR/1000
Where I is the amperage, R is from the ohms/1000' column above, and D is the total distance the current travels (don't forget to add the length of the neutral and hot together - ie: usually double cable length). Design rules in the CEC call for a maximum voltage drop of 6% (7V on 120V circuit).



What I'm arguing: is the AMOUNT of the resistance in a 14 AWG power line cord at 12 feet in length will not get as hot as a 16 AWG power line cord of the same length in a circuit running at 11.666667 AMPS (Bitmain Antminer S4 @ 1400 watts = 11.666667 AMPS).  This is THE SAME THING you pointed out in your statement I quoted below.

WE AGREE!!!  GAUGE (AWG) IS MORE IMPORTANT THAN LENGTH; since the length we are talking about is really not very long at all.


Cable heating won't really change, since while you'll have 3.3x the voltage drop with a 10ft vs 3ft cable and essentially the same current and will therefore dissipate 3.3x more power, the cable also has 3.3x more surface area to dissipate heat. That's why wire gauges are rated for a certain current without regard for length.

JT

When you said you changed over "...to a HEAVY GAUGE 3ft cable and no problems," I'm simply saying the "HEAVY GAUGE" [switching from 18 AWG or 16 AWG to 14 AWG] was what cut down the heat RATHER THAN THE LENGTH of the power cord.

Also, I'm not shouting when using caps.  The caps are only for EMPHASIS.

You and I are like riding on the same wave or something...

Cause I too had to put The Voice on hold [recorded it] so I could let my wife [Who also is interested in Bitcoin] watch it.  She actually put The Voice on hold to watch it.  We did eat first though.  I cooked us some pork chops, rice and green beans with sweet tea to drink.

Thanks for the one you provided as well.  I'm going to watch it AFTER The Voice.

David,
Good vid, I have seen him expostulate on the subject before but this was a good iteration. The Circle article was a very good summation of the basic idea many of us have been promoting for the past couple of years.

Is anyone else noticing that their error rate at the pool is swinging wildly the past couple of days?
It could just be something in my setup but I haven't been able to find it yet.
My error rate (normally between 2 and 4%) has been shifting between 1% and 24% every couple of hours for the past day or so.
I am looking at everything I can think of from the controllers, software and internet connection to the cables, PSU and board connections.
If anyone has any suggestions they would be appreciated.

Wow!

Sounds terrible no matter what "error rate" you are referring to.  My question is, "What error rate?"

Are you referring to HW errors?  Get Work Fail Occasions?

JT

The more I think about it, I wish those who left would stay here rather than leave.  We need more hashing power as a pool to maintain the "norm" each day.  I know some prefer they stay away to have a higher payout.  However, there is less chance of finding blocks as often.  It's a trade off.

GHash has gone from 57 - 60 PH/s a week ago to 63 - 65 PH/s the last couple of days.  They have gone from 9 minute shifts to 8 minute shifts over the last few days.  I think a lot of miners left here and went to GHash and/or BTC Guild.

I have all of my 7.4 TH/s right here at the moment.  I'm thinking about splitting my hashing power again between pools if the luck here doesn't change soon.  However, it is nice to see the size of the pay out per block found here compared to other pools.

I'm getting .02261740 average payout with 7.4 TH/s at the moment.  It can fluctuate depending on the total hashing power of the pool.  At the Dark Side, I can get .00285674 on average.  That means I need to find 7.91721(7.9) blocks on GHash for every one block we find on Slush.

What are some of the best 2nd-hand mining rigs at the moment around the 100usd mark?

I'm going to choose Bitmain Antminer rigs more than any other mainly because of "stability."

As for "2nd-hand" rigs, that is putting a lot of trust in the seller that all is okay with the 2nd-hand rig.

The best thing going at the moment for close to $100.00 USD [AND IT IS BRAND NEW] would be the NEW Bitmain Antminer U3 https://www.bitmaintech.com/productDetail.htm?pid=00020141017110427977rQGR3pcf06BE

$56.00 USD for each U3.  You can get two of these for $112.00 and have a total of 126 GH/s.

Yes, you could buy a "used" bitmain antminer S1 on eBay that has 180 GH/s but you also need to purchase a PSU.  That would put you over $100.00 or right at it.

The new U3 also needs a PSU but only requires one (1) PCIe to power it.  Depending on the PSU you get, you can power 2 to 6 Bitmain Antminer U3's.

Also, the new U3 is NOT stand alone.  You need cgminer to run this.  If you are not cgminer literate, as I am not, you may want to get an S1 on eBay from a reputable seller.

Features:

Scalable: Multiple U3 miners can be maintained by one controller running cgminer due to its USB port.

Hassle free: Setup consists of plugging in the USB and power cables and running Antminer CGMiner.

Cool: U3s remain cool and quiet due to its 80mm fan which quietly exhausts air out the side of the case.
