Can someone explain to me the stats and what each column means in the Miner Status tab or point me somewhere it mentions it?

Also, how do we calculate the total % of hardware errors? Looking at this https://bitcointalksearch.org/topic/m.3745184 it did the following:

HW / ( HW + DiffA + DiffR) = total percentage of hardware errors. Is this correct?

http://cryptomining-blog.com/tag/hw-error-formula/

Hey thanks! So overclocking to get 200 gh/s results in 2.8% hardware error. Not great for me...

6744 / (226556 + 383 + 6744) = .02885 * 100 = 2.88.

I will mess with it when I get back into town.

Random question. Do the settings like password and network settings reset when the Antminer loses power?

Only if you hard reset it. Not actually sure how to do that.

I've been at 200-205Ghs without problems, so thinking about trying the next level.

reading about OC to ~400GHs on these, anyone care to comment on their success\failure?

I have 5 S1's. 2 around 200 at 393.75, 1 at 200 at 375, and 1 at 180 no matter the clock. Watch your HW errors. It is basically just trial and error, as with most OC'ing.

how far has anyone ever cranked on of there up speed wise without a meldown?

My temperature balanced out to 43-48... This is with the Antminer set on the floor...

xoxoxoxo xoxoxoxo oooooooo oooooooo

This is what is showing for one of my miner.. but the hash rate seems to be about right.

Do you know if the "xoxoxoxo xoxoxoxo oooooooo oooooooo" is something i should be concerned about?
The temperature avg 42-45 for this miner.

What method do you use to cool your Antminers?

There was a video about facing the heat sinks outwards... and attaching 4 ARTIC PWM fans.

The total cost to do this is around $20-$25... Hopefully it should be worth it in the end.

4 fans on the outside blowing on the chips and 1 in the front pulling out. Here's an older pic, but you'll get the idea: https://bitcointalksearch.org/topic/m.4920949

I live by the Ocean/Beach....

It's cold at night, but temperatures are still 46-50.....

I'll buy a box fan this week to see if i can drop the temperature to 40...

no special msethods even running at 200 in the datacenter the temperature never gets above 44

it's averaging about 192 gh/s now - up from about 178 - perhaps I should have done some cleaning when I got it - but it's tucked away in a cabinet now in a data center and the luck of shush's pool is being good to me - so I'm not touching it now.

That's a very good idea, it's amazing how much dust these things pick up and a clean once every 3 weeks makes quite a difference, but if it's in a data center it shouldn't be as much of a problem.

FWIW: I get 203Gh/s at 400Mhz with decent extra cooling.

the top of this thread says to change new models to this:

however I don't have a '4e81' entry in my file - am I supposed to add the 4e81 entry?

No need, just change your file to this to clock to 400Mhz:

Code:

package 'cgminer'

config 'asic-freq' 'default'
        option 'freq_value'    '4f81'  #400M
        option 'chip_freq'     '400'
        option 'timeout'       '35'

        #option 'freq_value'     '4d81'  #350M
        #option 'chip_freq'      '350'
        #option 'timeout'        '40'

        #option 'freq_value'    '4c81'  #325M
        #option 'chip_freq'     '325'
        #option 'timeout'       '40'

        #option 'freq_value'    '0b81'  #300M
        #option 'chip_freq'     '300'
        #option 'timeout'       '45'

        #option 'freq_value'    '0981'  #250M
        #option 'chip_freq'     '250'
        #option 'timeout'       '55'

        #option 'freq_value'    '0781'  #200M
        #option 'chip_freq'     '200'
        #option 'timeout'       '70'

        #option 'freq_value'    '4f02'  #193M
        #option 'chip_freq'     '193'
        #option 'timeout'       '70'

Just uncomment the 400 setting and comment out the 350 settings

So I am getting my first Antminer tomorrow since UPS screwed up and didnt get it here today....I digress.

I bought this PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817182082 and it does have 2xPCIE connections, but on the same cable. Is that going to be okay?

No. You gotta have 2 separate cables. No Molex to PCIe either. You can start a fire by using just 1 PCIe cable. It is too much load for a single cable.

Hum... bummer. It does have a 1 x 4+4-Pin ATX12V/EPS12V Connector. Can I use that somehow by buying an adapter cable to PCIE?

Also, the power supply is rated for crossfire. 2xGPUs probably pull close if not more power than the antminer. A R9 290 pulls 336 watts when gaming.

No game can push the r9 290 over 300 Watts in real life. Crysis 3 @ 2560 x 1600 = 238 watts, May Payne 245 watts, Sleeping Dogs 285 watts.

Its a myth the R9 290 pulls over 330 watts, it is only rated this way from the factory because this is the max reviewers might hit using stress tests like Furmark and OpenGL and not in real life. I have built many rigs and they dont pull more than 265-280 using stock clocks under 24/7 load mining Altcoins. Gigabyte, Asus, Sapphire, XFX

I checked the Corsair 500 CXM I also bought and it is also the same. Here is a picture:

But looks like if I NEED to I can order this: http://www.amazon.com/Silverstone-Tek-Extension-Connector-PP07-PCIBG/dp/B00H45K3NS/

This may work but you are right on the edge. You should at least have a 650 with two separate cables.

I have a few 750s on the way and should be here tomorrow. I was hoping to be able to power one ant with each of my smaller PSUs and 3 ants via 2 750s.
