Hi. I built an extreme cooling system for the Raspberry Pi. It is composed of a short length of copper pipe with a cap on one end, attached to the CPU with thermal compound in between. It is filled with Liquid Difluoroethane (or LN2, if I can get some). It is possible to overclock the Raspberry Pi to a speed of 2.4 Ghz with this device.

Wait, WHAT?
You are dumping LN2 on a Pi
![tongue.gif]( "tongue.gif")
That is a 1.7GHz increase!!!! Please fo further and get a 2GHz increase on that, I will happily add you to my club if you can post any proof of it!
Wonder what a CubieBoard can do, it has a 1GHz stock clock, so is obviously binned much higher, maybe 3GHz???

Is that thing reading 11volts

And could you get a really clear picture, I would like to include you in my club

Sorry about the bad picture quality. I can't find my camera, so I had to take it with a phone. The 11 is the voltage multiplier, so it's not actually 11 volts.

I don't know how to upload the images. Flash wasn't on when I took the pictures. That was just the shinyness of the TV. Sorry, but those are the best pictures I can currently take. STUPID PHONE CAMERA!!!

I don't know what the actual voltage is. I kind of just randomly set it. 24/7 I run it at 1 Ghz with no sub-zero cooling.
Click "Insert Image" instead of "Insert Attachment"
Or upload to Imgur first then copy URLs here with IMG tags.

Figured out how to post pictures so that they are visible without DLing them.
This is how you fill it with Difluoroethane:

The rs spray is good, however a more efficient spray is:

Component cooler should get you there a lot easier.
We would store use those for experiments lol.

I think 2.999 Ghz is the ABSOLUTE LIMIT for processor clock frequency.
I tried 3.1, but it immediately crashed.

Any more attempts? BTW, ADDD MORE VOLTAGGGEE
3.355 Ghz!!!!!!!!!

Please don't ask me to overclock further because I don't want to fry my Raspberry Pi.

You may need to find a firmware that will remove those "safety" restrictions.Originally Posted by neo565
Tried setting multiplier anywhere from 11-21. Still didn't work.
I have one being shipped to my house right now so I'll get a chance to start playing with it. Unfortunately I don't have a dewar for LN2 though I might go the spray can route. Could something similar to the "zombie mods" for GPUs work here? I'm wondering if the power delivery bits aren't providing a stable voltage to the SoC.
