Are you linking to the correct article? That just looks like a review of a new P4.
Not much of an OC, 3.4GHz to 3.8GHz, which they shut down because it was so hot.

3.8GHz is nice for a P4E (Prescott) with such a small voltage bump, but a similar P4C can usually hit similar frequency ranges with quality air cooling and a moderate voltage bump.
The temperature is the concern here. Unless Intel revamps its cooling requirements, the traditional forced-air retail cooler shipping with P4C chips will likely fail around 3.4GHz for a P4E.
Even with quality air cooling, I do not see the current Intel thermal design specs allowing scaling beyong 4GHz for the P4E without a change in the cooling approach. Air can be used, but the size of the heatsink area will need to be increased dramatically.

It's the right article, but to run a cpu that hot....My personal knowledge of pentium cpu's is that they run cooler then Athlons, this one seems like it's not worth the money if your into overclocking!

Vr has a 3.2 Prescott at 4200mhz on air http://www.vr-zone.com/?i=424&s=13
Many Anand, Extreme System, OCAU etc users are reporting 3.7+ from 2.8 Prescotts---Vapochill/Prometia reports of 3.2 @ 4.6g's etc
Prescott is cheaper then the Northwood c's atm... | |

I wonder how that would perform against the northwood at that speed???? | |

you will never be able to get a p4c to 4.2 let alone 4.6

Tom's hardware guide got a 3.2C to 5.2 GHz. | |

| P4C at 5125 MHz P4C at 5125 MHz
These were done with radical LN2 cooling, however the P4C can often exceed 4.5GHz with a modified motherboard and vapor-phase cooling.
