The record overclock now stands at an impressive 7104 Mhz on a Pentium 4 system!
This is almost doubling the clock speed of the CPU and represents a real milestone in the world of overclocking…
You can visit their page over at PCtuner.net for loads more photos and more details on the construction of the system
As with the previous projects they use liquid nitrogen as a coolant, but this team from Italy have built a system which introduces liquid nitrogen in exactly the right quantities and with precise timing
This allows them to achieve a much more efficent cooling system than any of the previous attempts
They have also constructed a custom container block for the liquid nitrogen which you can see in the image below
Thanks to Mason Soiza for the tip on this one, as always if you know of a record beater then leave a comment and let us know…
The old record of 5.25ghz has been smashed by a new contender built by coolaler from Taiwan
Their system clocks in at 5.525ghz
Go visit their forum thread over at Xtreme Systems forums for more information on construction and lots of screenshots….
And thanks to Mica for the tip on this one - If anyone knows of any faster overclocks then please leave a comment and let us know!
UPDATE
This post contains the current new record
Following on from our last post on Overclocking, here is someone doing it right! Using an advanced compressor cooling system filled with liquid nitrogen!
They manage to achieve 5255Mhz with a chipset temperature of -38.5 and a heatsink temperature of -196 using the following configuration
- FSB Clock - 309Mhz
- System Bus - 1237Mhz
- Memory Clock - 206Mhz
- CPU Core Voltage - 1.88v
So there you have it, a new world record for overclocking! Looking forward to seeing this go further, it looks like heat transfer between the chip and the heatsink could be improved. We will keep you posted on any developments…..
You can also check out Tom’s Hardware guide who carried out the overclocking for more information
UPDATE
This post contains the current new record
The following video has recently been brought to my attention, it supposedly shows an AMD Duron being overclocked to 4ghz with explosive effects!
Although quite plausible, the resulting explosion is really caused by a gunpowder like substance. If you check out some of their other videos on google video you will see that exploding processors is nothing new to them 
You can check out the website of the videos author at http://www.mtaylor.be/
And after more delving, we discovered this article on Instructables by the same person who made the video. You can pretty much guess where i’m going with this one….
It’s actually quite a funny set of videos, took us a while to realise they were skits because of their accents. But we got there in the end!
Extreme Overclocking!
Get the truth here, first…. before it fills your inbox 
Not a lot of use for anything but check out a HDD spinning up at 15000 RPM!
The constructor has used a CD4070BDC xor gate, a HEF40106BP hex scmitt trigger inverter and a 4AC21 darlington transistor array to drive the 4 phase HDD motor
