In this instructables I will show you how to overclock a Raspberry Pi.
You don't need a heat sink or a fan, because the temperautre won't go over the 50-60 C (120-140 F).
Please vote for me in the Raspberry Pi contest.
Good luck with overclocking!

Step 1: Installing Raspbian

If you have already installed Raspbian you can skip this step.

For installing Raspbian you will need a 4gb SD card, a Raspbian raw image and Win32DiskImager (Windows) or dd command (Linux) or Rpi-SD card builder (Mac Os X).

Imaging the SD card


1. Download and install Win32DiskImager

2. Insert your SD card and open Win32DiskImager

3. Unzip the 201X-XX-XX-wheezy-raspbian.zip file (X is the date of your download)

4. Select the .IMG and select the correct device (!)

5. Now the SD card has the Raspbian Image


1. Start the terminal

2. Go to your downloaded .ZIP file

3. Use $ unzip ~/201X-XX-XX-wheezy-raspbian.zip (X is the date of your download)

4. Run $ df -h to see what devices are currently mounted

5. Insert your SD card

6. Run $ df -h again, the new device is your SD card

7. Unmount your SD card with $ umount /dev/xxxx (xxxx is your device)

8. Now write the image to your SD card with $ dd bs=4M if=~/201X-XX-XX-wheezy-raspbian.img of=/dev/xxx (xxx is your device)

9. The SD card has now the Raspbian Image

Mac OS X

1. Download and install RPi-sd card builder

2. Unzip 201X-XX-XX-wheezy-raspbian.zip file

3. Run the app and select the .IMG file

4. It will ask you if the SD card is connected, insert your SD card and press continue

5. Select your SD card

6. It will ask you to enter your administrator password, enter it

7. Look if your SD card is unmounted and press continue

8. After a while it says complete

9. Your SD card has now the Raspbian Image

Installing Raspbian on your Raspberry

1. Insert your SD card into your Raspberry Pi and connect your screen

2. Plugin your power, your Raspberry will turn on and boot Raspbian for the first time

3. You will get some options, you can skip them but I recommend that you select 1. Expand filesystem otherwise you will run out of memory and 3. Enable Boot to Desktop, I prefer the command line for overclocking.

4. Select finish, you will now be in the command line

5. Raspbian is now installed

<p>I did some simple testing running a timed fibonacci recursive algorithm in python and took temps. stock was 38C at 160s with HS and with fan was 26C and took 11s less to run at same speed and same for each overclock.pretty much 7% faster just by running cooler and at turbo with fan 31C max and only took 100s for same test. My thought is think of cooling regardless.</p>
I did mine manually with the config file. Mines overclocked to 1150 mhz and overvolted to 1.4 volts or 8 in the settings. I also have all the othe speeds to thier maximum allowable. With no heatsink or fan it still wont go above 50c so its got room for more overclocking. Mine runs just fine at those specs but i probably voided whatever warrenty i had.
<p>Me also reached 1150 mhz. Oh what I tried for 1200 :P<br><br>Then I removed inductor L5. From regulator RG1 (middle pin 1.8V) i soldered a wire to capacitor C16 (the lead farthest from RG1). Thats it!<br><br>Now I have 1400 MHz !!!</p>
<p>Easy to do; Usefull.</p>
Hey i am also in Toronto. Very cool projects you have. Would you be i nterested In a paid project? Need something done right away.
awesome! i am working on a temporary computer using my pi while my desktop is down. and wanted to speed it up a little this helps a lot
how do I get openarena to work with hdmi?
If you don't see the FPS restart OpenArena (there is a weird bug sometimes). If you have another problem please specify your problem
it just gives me a black screen when I try to run it on hdmi
Try adding this line to config.txt:<br> <em>hdmi_safe=1</em><br> I hope that will work for you
will that work with a hdmi to vga adapter? Will my screen resolution change?
ok thanks Kriskras99
You all should visit the RPi website for over-clocking caveats. You can easily &quot;bake&quot; your Pi and void the warranty. That said, if you bought two Pis, then fry away. There are much easier ways to over-clock on the site as well. Caveat emptor ! :- )
Maybe I missed it but did you ever show what you put your specific overclock settings to? I only see you showing what the default settings are.
This is nice
I kind of miss some recommended, tested values for the oveclocking and info about stability, temperature etc..
one note: Overclocking will void warranty of your Pi
http://www.raspberrypi.org/archives/2008 - overclocking has been supported for quite awhile.
wow, nice O.o
