P4 2.80GHz Overclocked to 3.917GHz
vwbus writes "The guys at Muropaketti have taken a brand new Pentium 4 2.80GHz chip, bought a pint or so of liquid nitrogen and overclocked it to an astounding 3.917GHz. The Finns describe how they put together the system on their web page, and luckily there are a whole set of pictures which demonstrate exactly what they've done, so you don't need to understand Finnish to figure it out. The pictures show wisps of nitrogen evaporating from the jar sitting on top of the CPU, and they publish some SiSoft figures to demonstrate the kind of speeds they attained."
The folks at Muropaketti have had a lot of practice with this cooling method.
Don't try this at home. If you feel tempted, watch three times in a row "Terminator 2", and remember you are not made of liquid quicksilver, or whatever.
Rome taught me patience and assiduous application to detail. Virtues which temper the boldness of great, general views.
person 1: "I just got this brand new P4 2.8GHz CPU. What should I do with it?"
person 2: "Get a Radeon 9700 and get on top of the 3Dmark2001 benchmark list at Mad Onion?"
person 1: "Radeon hasn't come in yet..."
person 2: "Compile some software?"
person 1: "Already did that."
person 2: "Create a new anthropomorphic CGI character with a Jamaican accent?"
person 1: "Tried it, but for some reason the CGI software refuses to let me. Something about digital rights management and George Lucas."
person 2: "Rip some DVDs to DIVX?"
person 1: "Already did that. I think it's what pissed off George Lucas."
person 2: "Ah hell, lets just dump some liquid nitrogen on it and overclock it. It'll be like the Fast and The Furious if it blows up."
person 1: "Duuuuude! Great idea!"

If you've seen this article before: yes, I know. Some people haven't. This is for them. Thanks.

In university, we got an old huge VAX which we had to run with open windows, but after a while they told us to stop. Not because of the immense power drain, but because the palm trees were starting to push out the birch, fur and pine trees in the local forests and they were concerned that tigers were next. This was in northern Sweden, BTW. You Americans can probably relate to Minnesota, if it helps.

Oh great, then intel would trademark Intel Outside as well...
We have modified TurboPLL-module on Asus P4T533-C motherboard which allows us to use higher front side bus.
Thanks to this module, when we set 145MHz from BIOS, the FSB is actually 186MHz.
You can check out the pictures of modified motherboard here.
CPU still works fine and actually we are already planning for the next test with liquid nitrogen
Earlier we tested Pentium 4 2,4GHz CPU with liquid nitrogen over 20 times and it's still kicking
We dry the components very carefully after the test with compressor.
See this this link for full instructions and pictures.

Now it can wait on the hard drive faster.
If you aren't part of the solution, there is good money to be made prolonging the problem
Actually there were problems in going above 2.2GHz since that is negative number (using 32 bit signed). See here for example.
Any chance to underclock this beast at, say, 1.4 GHz w/ passive cooling?
:( ). It's occurred to me that 350MHz is probably too much for a firewall (plus, I need a box for experimentation), so I set out to try and build a simple, low-profile, low-speed box for a firewall.
I've been thinking about that a lot lately, myself. I'm trying to rebuild my network at home (now that I have a cable modem, but don't start me on that!
Can't be done. Everywhere I look, I see 1GHz+ systems. I could find 500 MHz K6 CPUs, but that was about the lowest. And anything on eBay is both too fast and too big. I want something simple and small, that I can maybe put a four-port ethernet card into. Something like a 1U PIX, but running BSD.
This becomes more of an issue as I think about set-top boxes -- I want to be able to do video/audio/games/web to the TV, but I don't want to have whirring hard drives or whiny fans in my bedroom. Once again, I need a decent speed, but not super kick-ass (especially if I can do MPEG decoding in hardware), but, again, I'm out of luck. Stuff that slow (and cool) just isn't easy to find.
'course, I'm not looking *too* hard, either. And, no, I don't want to go the PC104 or SBC route -- if it comes to that, I'd just buy an Athlon 2600 and retire my Duron to firewall duty, for the same cost.
