Now this is overclocking!!!

anyone gone this high yet????

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.

Wow, that does not look good.

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

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.
