World record 4424.99MHz

Any one know how <A HREF="http://holicho.lib.net/bench/h_clock.htm" target="_new"> this guy </A> done it. How he unlocking the p4 multipiler.

 

[Crashman]

No, he didn't unlock the multiplier, why would you say that?

[sschian]

The multiplier will increase automatically when the FSB increase?

 

[Unolocogringo]

No that is a P4 2.5ghz chip with a 100fsb increased to 177fsb. No multiplyer adjustments can be made on an Intel CPU.

I aint signing nothing!!!

hmm yes, a core temp of -175 (farenheit i'm assuming) on one of the other OC's if you scroll down. that's even lower than my volcano 7+!!!

 

[monkeyspank]

-175 degrees C dude.(on the thermometer).
That's cold.

Absolute Zero is about -270 degrees C and, in theory, impossible to achieve.

These guys are nuts. I'm impressed.

probably with liquid nitrogen and btw absolute zero is -272 i think they've reached it within 100th of a degree but caus of E=mc^2 saying mass is energy it can't be reached caus the electrons in the atoms = mass still move thus prodcing tines amounts of heat

Remember the time You used 20Mb harddrives

Actually, relativity has little to do with it. I believe the correct model would be the Heisenberg Uncertainty Principle. (uncertainty in position)*(uncertainty in momentum) >= (hbar)/2.

Assume a substance IS at absolute zero. That means there is no kinetic energy (the mass energy relation is not important here). No kinetic energy means no particles are moving and we are 100% certain that there are 0 units of momentum, i.e., the uncertainty in momentum is 0. If this is the case, then the Heisenberg Uncertainty Prinicple is violated (NOT GOOD!).

No system that we observe is capable of reaching absolute zero. "Almost" absolute zero we call "Zero-Point Energy" or "Zero-Point Field."

Off topic, I know. I just thought I would reply to something that I actually know a little about.

More O/T...

I'm not impressed at -175C. No way would the PC warm my toosies in the winter.

are you sure it isnt photoshop stunt????

Every point I make has 'n' perspectives!
Boy do I need a <i>disclaimer</i> for my every word?

No. Its not.
He just got a rather rare 100FSB P4 2.5 C1 stepping and cooled it with nice Liquid Nitrogen.

Liquid nitrogen has a BIOLING point of -196C, which explains the cpu temp.
At such low temps resistance is alot lower, and thermal energy produced is dissapated AMAZINGLY quickly and efficiently.

One can do amazing things with Liquid nitrogen, but it aint too practical.
Imagine having a PC in your room that need a huge cylinder of liquid nitrogen to cool it, requiring the cooler to be topped up every 15minutes or so and vapour pouring from your case all the time?
Then there is wear and tear on your components, components cracking and dying due to the temperatures involved and problems with ice formation.

Think ill stick with my MCX-462.

holy jeez.......

 

[HolyShiznit]

I'm impressed. A stupendous job.

I'd like to see someone violently O/C a much weaker initial setup. It'd be cheaper to replace any broken parts that way too.

 

[vagabond]

If this isn't a photoshop stunt like girish says, you still have to give the guy credit for doing it. Yeah it isn't practical for daily use but he did get it up there...4588.49Mhz jeeeeweeeeezzzzzzz!!! :lol:

No matter how short-lived the components are (who knows maybe he's Enuit and doing his OC'ing at the northpole)

The Japanese use LN2 to get those insane overclocks for a few minutes to get the screen shots and run pi for a world record.

I use extreme watercooling to break 4Ghz now, one exception is my CPU has hyperthreading and I can run 24/7

You are limited to what your mind can perceive.

 

[vagabond]

That's what I figured. I mean if they can afford to waste CPUs like that for the sake of setting a record, why not? I couldn't afford it. Not with the economy here in Europe being so shitty!

Not really much difference in TOP-FUELERS. BAD!!! If you can afford it. Know what I'm sayin'?!

Keep in mind it was probably OC'd just long enough to post. LN2 jobs are usually really short (& really expensive).

Also keep in mind that @ -120C theoretically speed should double, so in terms of theory, the LN2 guys are way behind their performance envelope. Whereas guys using phase change (like ChipCon, VapoChill, &c) are getting results "close" to this that are rock stable and don't burn the hardware life.
