The exit command !wq doesn't work for me i have to use :wq

I have 2 ant's.  Will post more after further testing.  One OC's very nice the other default clock speed seems to work best.  Both batch one.  It seems hit/miss but know it will be better on batches to come since they know the cause of slowdown in the batches they are offering compensation for (coupons/partial refund in account).

A few kilowatts really throws the heat in mid summer. Almost wish this was January.
I'm terrified to leave the house in case a cable melts and 'POOF!', FD calling me to tell me that I screwed up. My 16gauge cable melted or something random I overlooked while frantically getting them online and neglected the cooling.

Soooo hot..

Well good news for you, i got one unit that do not handle any OC and the other one perfectly. (OC to 250 mhz at 503 GH/s)

Do you need to connect the other 2 power connectors to OC?

Thanks for this Goxed!! This will help a bit with the ROI!

I am currently running stable for the last two days at roughly 455GH/s at frequency 225. From frequency 218.75 (The stock my unit shipped with)

Temperature up by only a couple of degrees.
37 --> 39
38 --> 39

Fan RPM up by about 600
1260 --> 1800
1020 --> 1620

You can try that in visual mode
sorry! visual mode does not work on the antminer's vim.
:v
:gg
:shift+gg

Its not possible to use a single shortcut the select all in nano or vim.
Multiple shortcuts will work that's a hard job. Using mouse will be more easy.
An enhanced version of vim called vim-enhanced may be used.

do yourself a favour and install nano, it's an easier to use (albeit less capable) text editor.
opkg update
opkg install nano

Just press "i" on the keyboard when the file is opened.
The other one was a typo. After editing you need to press ESC button and type the below code and press ENTER to save the edited file.
Upon window close PUTTY will auto close the connection. Or may manually exit as said in the earlier post.
CODE:

Pre then type :wq
This will take you back to the prompt. Then type "exit" to ensure you close the connection. At this point you can close your terminal program. Reboot or power cycle the Antminer to complete the change.

Thanks for the help.  I was able to login via putty and get the screen with the freq values.  However, not sure where on the screen to type the "i" and "!wq" commands.

Anyone with info on overclocking steps between the 218.75M and 225M? Like 220M. What are the values to add in?

i have my S1´s overclocked and no problem. But with S3 im not that confident to OC

I would like to know difference of W for OC and non OC and temperature also

This has me curious as well. I never did overclock the S1's I had, but I'm thinking of overclocking these dudes. I'm really hesitant, though, on the count of them already needing to clock them to 218.75 stock :|

Was thinking of nudging one up to 225, but don't want to risk burning my house down.

Goxed,

You got a really nice unit if it's remaining stable at 250 clock and 504GH/s, congrats!  Mine apparently are part of the batch that caused Bitmain to set the clocks back to 218.75.  I tried 225, 237.5 and 250.  I would consistently get "x" and "-" in the ASIC stats and the units never got anywhere near the 504GH/s you're showing.  I left them running like that for 7 hours while I slept last night, hoping things might get better over time.  When I woke up and checked, Ant 1 was averaging 450GH/s and Ant 2 was averaging 387.  At 250 clock.  I set them back to stock and after 13 hours I'm at 441 and 439 with 0.0002% and 0.0004% HW errors.  All ASICs are "o".  It's definitely not a power issue - I've got an EVGA 1300 G2.  I even went so far as to hook only 1 up at a time on the PSU to see if it made a difference.  All 4 PCI-e connected.

Also, that solution for the random beeping did not work for me unfortunately.  They still randomly beep at me.  It's like they're just letting me know they're still going.  If somebody does come up with a valid solution to this, I'd be very much... well, my little lady will be very much appreciative of it

As for temps and fans, mine are in an ambient 22C room.  Ant 1 shows 38/39 and Ant 2 shows 39/40 on stock speeds.  Fans are 1560/1380 and 1620/1380, respectively.  With the same PSU as I have, philipma1957 reported 665W at the wall to run them both at stock.

This.

Tks for the guide. I am still awaiting delivery. Do you need to connect the other 2 power connectors to OC? and what is the temp difference between OC and default?

can someone tell me if opkg is locked down?

edit: also, what's the flash utilization ('df -h')?
