CPU-Z world wide #1 score @ 8.1GHz

''Earlier in February, Team Finland reached 6.7 GHz with an early version of the Phenom II X4 955 chip using a similar configuration. However, neither LimitTeam nor Team Finland has overcome to the world-wide #1 score listed by CPU-Z. Clocking in at 8.1 GHz, a user simply named "duck" overclocked Intel's 65nm Cedar Mill Pentium 4 631 processor back on July 20, 2007 using the Asus "Commando" motherboard and 2 GB of DDR2 memory. ''

Just read that over on Tom's in regard to the recent OC of the AMD Phenom II X4 955 Overclocked to 7.1 GHz.

I was only just getting into PC's with the P4. How the hell could you get one up to 8.1 !!!!!!!!

Ln2.

The netburst architecture, in theory, was good up to 10ghz.

I had guessed LN2. I didnt think old architectures were very good at the OCing.

As you say, extreme cooling. The Pentium Netburst based CPU's (particularly from the Prescott and later) could generally hit high frequencies but were only really limited by their rediculous heat outputs. Intel were slowly getting this under control and by the time that they released their refreshed 90nm 2mb L2 Cache Pentium 4 6xx CPU's, heat wasn't so bad and around 4GHz on air was usually the norm. The last of the Pentium 4's were the 65nm die shrunk Pentium 4 6x1's, which were pretty mad overclockers. They didn't get much hype as the Athlon 64's were pretty much blowing them out of the water, but it wasn't rare to see the 65nm Pentium 4's hit in excess of 4.5GHz, some which even made it as far as 5GHz on air cooling.

Don't forget however that clockspeed isn't everything and even at 8.1GHz, such a Pentium 4 wouldn't be anything special at all!

Without going too off topic (sorry) does anyone know what the clockspeed world record is on air cooling?
