BITMAIN Antminer S1 support and OverClocking thread

[goxed]

This thread is for support related discussions of the BITMAIN Antminer S2 hashing device

How to overclock your miner to 400MHz / 205GH/s. My suggestion is to clock them at 375. 400 is a bit too harsh on the voltage regulator.
All clock speeds including 375MHz work on both revision of boards.

The miner will draw 500 - 525Watts at the wall (110V mains) after this setting

A) ssh into your miner

B) edit the following file
/etc/config/asic-freq

C) change timeout to 36, freq_value to '0780', 'chip_freq' to 400.
For miners with build date 2013/11/4

Code:

root@antMiner2:/etc/config# vim asic-freq 

package 'cgminer'

config 'asic-freq' 'default'
        #option 'freq_value'      '0780'        #400M

I have a question about how multiple pools are handled.

Are pool 2 and 3 just backup pools in the event the miner can't connect to pool 1?

I think so the default is failover.

Guys heads up on overclocking your AntMiner
202GH/s






@ 400MHz / 204GH/s the hw error % is 63,253/(63,253 + 3,543,296 + 41,984)% = ~1.7%, which is rather fine for a system operating at its limits Kudos to Bitmain engineers.

that you? Im not surprised these can get 10%, from the sounds of it the fan isnt working/needed at full capacity often. (Mine is still with UPS, who basically failed to come today and no note was left

yup dat's me . The fan's a very high performance unit. It's basically silenced down so that they are quiet. But for me, I want my 4.75BTC back. I am also using the PSU fan as a pull unit, for slightly. better cooling. This package is supposed to be UPS Intl' priority. Maybe you could call them up and find out what's up. This is not done

good job goxed... is this something possible for an average joe like me?

If you know Linux command line operations it's a piece of cake.

 Am I overlooking something, or is there no way to adjust CGMiner parameters in the webgui ?

Nope with GUI unless you have a special version.

I would say a bit, pool hash rate is between 196 and 205 GH/s at 256 difficulty.

Is the 'chip_freq' parameter just for the reported frequency in the miner status GUI?

Changed IP config, mined on wifi for 5 mins while I set the IP address to a static address at 192.168.1.60 on the lan, applied settings and since then the system has been uncontactable. Occasionally my dhcp server sees it request an IP address but I can't talk to it and then it disappears again from that IP address. Tried removing wifi aerial and powering it down and up, tried removing lan cable and powering it down and up, tried setting static addresses across all 192.168.1.x and 192.168.2.x and still can't talk to it anywhere. Plugged directly into it with a laptop, plugged it into a router, did everything I could think of to talk to it and can't seem to.

Anyone know how to reset it somehow back to defaults? Only button on the board has a meaningless "S1" label.

Hmm, I set a fixed IP address on the WAN interface of my Antminer (to match the subnet of my home LAN)

 Also at one point I had enabled WLAN simultaneously with WAN, and the device started using both interfaces simultaneously.
 Does yours still connect to the WLAN access point? If yes your best bet may be to try to log into it when it connects via WLAN.

Yes that is what is seems to do. freq_value controls the actual frequency.

Tried connecting on every possible interface that was already set up and I can't even ping them any more. The dhcp server acknowledges a request but I can't ping it. Tried hard wired to my laptop again on various possible subnets as I said, nothing seems to work. Only thing that comes out of it is a dhcp request when packet sniffing but it never gets beyond that.

i guess then you probably need a new OpenWRT card. I heard BITMAIN had to mail out a few to some customers in China.

And I'm guessing you're right. Probably a more accurate answer than having me waste more hours getting nowhere with this thing when I have so much else to work on. This can start a pile of bricks in the interim. Yes I know it's my own fault but no reset?
