Pentium 4 Overclocked to 7.1GHz, Sets World Record

CowboyNeal posted about 9 years ago | from the unstable-mutation dept.

Intel 392

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.

World record? (4, Insightful)

World record for the P4 or for a single x86 processor?

Re:World record? (3, Informative)

Anonymous Coward | about 9 years ago | (#13311159)

Yes.

He overclocked the Intel Pentium 4 670 processor with stock speed of 3.80GHz.

The processor system bus was overclocked to 1520MHz.

processor's voltage was pumped up to 1.70V, significantly higher than default setting; memory latency settings were CL4 3-3-4, memory voltage was set to 2.3V.

Still no word on what his 3dmark2005 score was! (CPU and Total, of course)

The OP suggested that it's a record for calculating Pi, not just for clock speed. That's not for computers in general, obviously, and probably not for single processors either unless you set restrictions on what counts as one processor (one x86 processor with no multi-core technology?).

Re:World record? (3, Informative)

magarity (164372) | about 9 years ago | (#13311246)

Calculating pi is a series of mathematical operations where you can't do the next one without the prior because you need the remainders. Supercomputers are super due to a heck of a lot of CPUs all working on different parts of a problem that can be broken into chunks. How exactly do you break a series of operations that depend on the priors into chunks for a supercomputer to rip through? So anyway, it looks like this calculating pi is a record in general, not for just a PC. It's a speed job for a single CPU.

Re:World record? (3, Informative)

keesh (202812) | about 9 years ago | (#13311305)

Not true. You can get any digit in base 16 of pi without needing to know any other digit. This means you can get groups of digits in any base by only calculating a relatively small (maximum 16 * base) number of other digits in base 16 and converting.

Re:World record? (5, Informative)

pooly7 (892966) | about 9 years ago | (#13311308)

That's not exactly true, you can compute the Nth binary digit of PI without the need of the previous one. Here is the guy who discover it : http://fabrice.bellard.free.fr/pi/ [bellard.free.fr]

BurntNickel (841511) | about 9 years ago | (#13311319)

Calculating pi is a series of mathematical operations where you can't do the next one without the prior because you need the remainders.

That's not entirely true. There exists a digit-extraction [wolfram.com] algorithm for computing pi [wolfram.com] starting at the nth digit, without the need to compute any other digits. The only catch is that it only works on base 16.

Use the BBP Formula [wolfram.com] . Pifast is just a benchark, like all benchmarks it's rather silly. The record is for PCs, the top 500 supercomputers [top500.org] are benchmarked using another silly benchmark (LINPACK).

PsychicX (866028) | about 9 years ago | (#13311216)

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?

world record? maybe in mhz, but not in actual performance. I don't want to start a holy war here, but what is the deal with you overclocking fanatics? I've been sitting here at my freelance gig in front of one of these nitro overlcocks (a 6.5 gighz p4 512 Gigs of RAM) for about 20 minutes now while it attempts to copy a couple of meg of mp3s from one folder on the hard drive to another folder. 20 minutes.

At home, on my Pentium Pro 200 running NT 4, which by all standards should be a lot slower than this overclocked machine, the same operation would take about 2 minutes. If that.

Re:World record? (1, Interesting)

My Powerbook G4 using Mathematica can compute Pi to 1000000 places in about 19 seconds. How can this be any kind of record, or anything to write home about.

Since mathematica's performance for this algorithm is directly related to clock speed, I'd expect to see something like 3 seconds for that clock speed, and even faster for optimised code
