Hi all,

Has anyone got a Pentium 4 EE 3.73GHz Engineering Sample?

If so what are the markings on your chip and how high have you overclocked it? What motherboard and RAM?

For those who have the aforementioned chip but in retail/OEM format it would be good to hear your overclocking experiences also.

Thanks,

can you even get ES cpus for retail?

You would have to get them straight from Intel .. some how.

No you can't get ES's through retail. Despite this some people out there might have one and if so this thread applies to them. If however someone has such CPU but in OEM/retail format then I'm also interested in what they have to say about it in terms of overclocking.

In essence this thread seeks answers from anyone with a 3.73GHz P4 EE CPU.

I have a P4 EE 3.46 ... I read about it and I thought that P4EE's allowed overclocking from the factory

*Edit* here is a snippet from the article I read.. I don't know am I allowed to post another sites link here? ...but just google "pentium 4 extreme edition overclocking" and its the 5th one down

"Introduction

Overclocking socket 775 Pentium 4 processors has some particularities, comparing to overclocking done in other platforms.

The first difficulty is that since the first Pentium 4 the clock multiplier is locked. Only engineering samples (that are made for testing) and the Extreme Edition models have the unlocked clock multiplier. Engineering samples are identified with the letters “ES” and are not available in the market. Some manufacturers, such as ABIT, have created motherboards that can bypass that protection against overclocking."

well, no motherboard manufacturer has ever come up with a way to unlock the multipliers. its not dooable. you can overclock via the front side bus tho.

as far as i know of, only ES's will have the multi unlocked, while regular EE's won't. some motherboards allow you to drop the multi to 14, but this is a function of speedstep, not truely unlocked multipliers.
