Pentium 4 Overclocked to 7.1GHz, Sets World Record
Netmonger writes "This Japanese guy
overclocked a Pentium 4 to 7.132GHz!! The system managed to calculate pi to 1 million decimal places in 18.516 seconds, setting the world's record." The article notes that a Pentium 4 had been overclocked faster earlier this year, but at that speed it was not possible for the machine to function beyond BIOS. Of course, they'd yet to try diverting power from the dilthium crystal reactor to the deflector array.
How long can the machine last at that sort of overclocking? How much experience have others had with lifetimes of chips once you overclock them by a lot.

My question is this. Tom's Hardware put a P4 under liquid nitrogen a while ago, put the northbridge chipset under a phase change compressor, and replaced the motherboard power converter in order to supply enough power to the chips, and they were only able to achieve 5.25GHz max. What did this japanese guy do different that gained him another 2.5 GHz? Is it entirely a result of using newer chips with new manufacturing technologies like Silicon-On-Insulator (SOI)? Or did this japan guy do something that Tom's didn't?
You want that render to finish before lunch? Just slide in a brick of dry ice and watch the steam come out the sides as your motherboard's temperature sensor gives the go-ahead to crank the clock up to 7 GHz.

Comment taken from the website:
"18.516 must be wrong. My athlon 2400+ did
1 million places of PI using FASTPI in 4.4 secs.
Maybe the number should read 1.8516 secs.
That would be more in line with factors of
speed differences between my 2400 and
the P4 system."
Cooling and power requirements aren't the only issue, since at those types of frequencies you are likely to be interfering with radio frequencies, unless you have really good shielding.
The real future is asynchronous CPUs, that are actually clockless. They generate much less heat and consume much less power. The only reason that they aren't replacing the current batch of chips fast, is that all chip design and testing processes are built around clocked CPUs.
