2 questions..

1. best pool for the A3 right now? got ALL mine coming tomorrow

2. has anyone OC'd this thing yet? what are the options? and hows it work when you did?

Thanks guys

Pushed mine to 625mhz with no real gains. I think these things are being pushed to their limits with the factory clock. Tried 650mhz, started getting a ton of HW errors.

Thanks a lot for your answers, it's helping.
Well now I have another issue, it seems the tab "miner status" doesnt show anything anymore when i click on it...

Is it just the pool isnt configured well or something else? I m a bit worried i harmed the miner by putting the frequency to 750.
Thanks

Go back to your system page and see what it says under hardware version?

Probably just your miner configuration settings are wrong?

Wow, Over 2200 new A3's went online in the past 24 hours !
Network went up from 500TH's 4 days ago to 2700THs..

difficulty is at 2.3T

Your looking at pool hashrate...total network hashrate is up to 3600 TH and its reaching parabolic growth right now lol. Looks like its going way over 10 Petahash.

Hi,
I connected mine on miningpoolhub and get that :

How come Im only at 123 GH/s?

Go to miner configuration and click on the advance settings tab and then chose default from the drop down menu.

You're frequency is way too high

Ok thanks, it's better now, 329 GH/s in average. However, it is far from the 800 GH/s announced.. any idea how to get there? Should I just wait for the miner to slowly grow to 800?

You have xx00 in your ASIC status section that means your boards-chains aren't working right, id try resetting from the front of the miner, something like a small pin to stick in and hold for 10 seconds and release.

When working correctly it will be all 000000 in asic status for all 3 chains

If you're seeing much higher than 11A power draw at 120V, check your power cable, make sure it's not getting warm. One unit drew 14A on an 18 gauge cable, causing the cable to get a little warmer than i was comfortable with. Switched to a 16 gauge cable and it dropped to 11A and the cable stays cool.

Might sound silly. How does the AWG of power cable impact how much it pulls? Will 14 AWG be even better and will pull lower than 11 A?

Lets say you draw 1400W from the wall which at 120V is 11.6A. (1400W/120V=11.6A). But in this case the 18 gauge wire is too thin which is making it act as a resistor (which is why it gets warm / hot to the touch). Because the wire in this case is acting as a resistor it will drop some voltage under load. Let's say it drop's 15V making the line voltage at the miner 105V. The miner still pulls 1400W regardless (1400W/105V=13.3A). So the amperage went up to compensate for the drop in voltage and the wire / PSU gets hotter as they are dissipating that extra energy as heat.

This is why many recommend 240V, as 1400W/240V=5.8A. The energy consumption of 1400W is the same (actually a bit less as the PSU is slightly more efficient at higher votlages), but the amperage is much lower which means you can fit more devices on a single circuit.

Basically if your power cable is warm, you are dropping voltage and wasting electricity. Not to mention creating a potential fire hazard. For this miner i would say 16 gauge power cables are a minimum requirement at 120v. At 240V 18 gauge should suffice just fine.

check the ASIC# column, there should be 60 ASIC chips on each board.

It's possible one of your boards are dead or may just need to unplug and regplug your PSU cables

It seems that avg, which means it's counting all the time you mined at 100 gh/s. If thats the case, it will increase with time

I noticed the same.

Anybody out there overclocking? wouldnt this be the best time to do it since payout is higher? does it void warrranty?

A friend has it running at 656MHz @ 301GH/S with 0 HW errors. But beware, this thing is heating up like hell. Good thing that its winter here

Also at that speed the 1600W rated APW3+ is at its limits! And yes, you are voiding your warranty so dont do it Wink

Not doing it, just asking for a friend...
So, the minute it goes over 600 the warranty is gone? if that's the case, then no need to look back lol

Thanks for sharing your opinion...

btw, 301GH/s per board or you meant 901?

Yeah, dedicated circuit is not the issue. APW3 not able to provide anything more then 1200 W on 120 V is the issue. Thats why I am planning to use APW3 and another EVGA 750 W PSU to power a single A3

Actually, I'm doing fine with only 1 APW3++ with the Antminer A3 on 120V.
Right now is consuming 11.54 AMPS and 1337W.
No issues at all.

Thanks for sharing.

Why is it so different for everyone? Sad

Some posting 1500 W and some 1400 W. Will power cable guage matter? Like 14 AWG pulling less power than a 16 or 18 AWG? Might sound silly. But what else could be the reason. They are not overclocking though.

I have mine set at 625 mhz with highest chip aroudn 80c and about 100 hw errors an hour.

Might bump it up a bit when I get home.

Payout is higher and it does void warranty. So it's really just the question if it's worth it or not.

Network hashrate has gone 4x since I plugged my miner in 2 days ago. Profitability going down by the hour.
