1. Download putty.exe
2. Load up putty, and connect to the IP address of your S1.
If you are prompted, click "Yes"
3. When prompted for a username and password, "root" is the username and "root" is the password
(without the quotes).
4. Navigate to the configuration directory by typing in the command
cd /etc/config
5. Now, type
vim asic-freq
6. This opens up a basic and hard to use text editor. Press the insert key on your keyboard.
This will put you in edit mode. Edit the file as follows if you want to OC to 200 GH/s. If you
want to step it up to 190 GH/s only, use the #375M setting. Your configuration file probably
does not contain the 3 lines associated with the #375M setting. I add it to all of my S1's,
because I like to step up to 190 GH/s before going all of the way up to 200 GH/s.
When you are editing, note that lines that start with # are "commented out". So, by removing #'s,
you are activating those lines. If you overclock and want to return to normal, putty back in and
comment out the 400M lines and remove the #'s from the #350 lines.
7. When you are done editing, hit the escape key, followed by ":wq" and then enter
(don't include the quotes). This stands for "write changes and exit". If you need further
assistance with text editing, google around for "How do I do ____ in VIM?" and you will find
many good examples. It can be tough to use.
8. Finally, exit putty and reboot the device. As soon as you can, access the miner status tab
and watch for lots of X's and watch those temps. If it gets above 50C, I'd shut it down and
adjust fans. If you get lots of X's, your PSU may not be good enough, your temps may be
too high, or perhaps your S1 doesn't overclock very well. Some do, some don't.
Warning: Overclocking may void your device warranty! I would recommend overclocking
only to 375 which is 190GH/s unless you put additional cooling onto the antminer
