Whats a good P4 to OC to 4.0Ghz

I can give you a cpuz verification if desired?

And i dont think mine is the C revision, according to cpuz it's the 2.8 400FSB D1 revision.

So, what's the doubt? I said "C", but anyway, not impossible. Just have to be lucky with the chip.

Oops lol, my bad. I still had morning brain.

I think that the best p4s were the Northwoods. If they just kept the basic Northwood design, gave it 1mb cache and moved it down to 90nm it would have been a MUCH better CPU than the Prescott could ever hope to be. Well, that's my idea. Im most probably wrong.

Im most probably wrong.The Northwood's were the best P4's due to the shorter pipelines. Getting 4GHz out of them was no small feat. Anything over 3.6-3.7GHz was something to be proud of. Don't forget that they suffered form SNDS, which made 4GHz hard to reach with reasonable cooling, as >1.70v was a death sentence for them. There were some lucky chips, notably the M0
stepping which were dubbed the "30 cap" chips, and were basically EE chips binned down.

It wans't the shorter pipelines holding back the Northwood. It was its .13 mircon size, as evidenced by Conroe's short pipeline yet Northwood-like speeds. A Northwood on a successful 90 nm die shrink would have been quite a formidable cpu.

LOL, Conroe is at least 30% better per clock than Northwood, owing not to its die process but to its design.

 

[joefriday]

LOL, I wasn't talking about Conroe's performance, I was talking about Conroe's scalability DESPITE its short pipelines.

 

[Crashman]

Yes, the Northwood probably could have scaled to 4GHz at 90nm, after fixing the problems that arrise from the transition.

I didn't say that the short pipelines held it back. Just that it performed better due to them. I also commented that 4GHz out of Northwood was hard to reach.

ah.... even I can misread a post. Sorry.
