P4 2.4GHz Coming April 2nd!

me too....
my 1.8a is hitting 2.7 no sweat.

but i do wonder if these 2.4's can o/c 50% or more like 1.6a's or 1.8a's.
that'd be crazy..... 3.6ghz
 
I don't think many are likely to hit 3.6GHz with the 2.4.

However, some of those on the Japanese/Taiwanese overclocking boards did report 3.3GHz aircooled results for preproduction/production 2.4 selling on the grey market.

Typical max air cooling results for the 2.2A are 2.9GHz to 3.0GHz, so I expect we'll see the P4 2.4A increase that slightly to 3.0GHz to 3.2Ghz. Perhaps those with watercooling setups will do higher...
 
It remains to be seen if the 2.4 is really much different in terms of chips versus some of the 2.0 and 2.2 now....Many hit that speed easy so naturally it wouldn't take that much....

I think you are getting carried away...in a perfect world maybe...
 
Duvie,

Well, I've seen reports that indicate Intel is and has been "binning" 2.4 parts since January. If true, that means the 2.4 parts can do something that the 2.2 parts can't...
 
Yea thats good to hear .... and then they will have the 2.26Ghz, 2.4Ghz (533Mhz fsb) in a little wile too 😀 Cant wait! I might concider a 1.8a .... I always wanted a P4 till back when they were launched. Now I want one bad and im getting the money up (thank god) 😀

With the 2.4Ghz P4 you may expect 2.93GHz with air cooling (533MHz FSB). Engineering samples are already out there and have been proven to run at this speed. That's at around 1.85V Vcore so a lot of heat and should only be undertaken if you have the head for cooling implementations to keep it stable.
 
At 1.85v heating isn't the only concern....That is too much volatge and can drastically effect the transistors in the cpu itself....If I wanted to go to 1.8v which I coulf with the asus I may be able to get 2.6ghz, but at potentially a damaged cpu...

I don't consider those reasonable oc's to myself becuase I know what I have heard and read and 1.85v would be something I would never run it at...so maybe the 2.4 realistically can do 2.75-2.8ghz aircooled...

I still say this is hogwash.

Electromigration is normal; if it weren't for electromigration, processors might last tens or hundreds of years. The danger of electromigration is that the processor will eventually require more voltage to remain at the same speed, and will need to be reduced to a slower speed at the given voltage to remain stable. Eventually, after a substantial period of time, it may stop working completely. However, this isn't something that could occur to a processor overnight, or even over a period of many months. Even at 1.85V on a P4 (assuming reasonable temps), it will probably take years.

Electromigration occurs just from running processors at 100% usage. It occurs when running processor intensive tasks. Some have suggested that electromigration occurs (on the Athlon, not just the P4) whenever the processor temperature exceeds 50C.

Primary electromigration risk occurs from increased temperatures; failure from electromigration increases exponentially with increased temperatures. That said, the copper interconnects in the P4 can carry ten times as much current as aluminum wire, and serve to allow substantially increased temperatures with minimized electromigration risk to the processor. That's part of the reason why Intel moved from aluminum to copper interconnects with the "Northwood" P4--so they could reach higher clocks, and tolerate more heat, while still preserving long-term (essentially indefinite) reliability.

What's a real world example of electromigration? People who overclocked their Celeron 300A @ 581MHz have begun to find, after two to three years, that their processor no longer runs stable at that speed. Some of those who ran their Celeron 300A @ 581MHz for several years now find that it only runs stable at 450MHz or 462MHz. That's due to electromigration. Actual processor failures due to electromigration are very very very rare, considering that few people keep their processors for more than five years.

What is the worst danger one can realistically expect to face from electromigration with the "Northwood" P4? Well, if you don't have good cooling, you may find in three years that your P4 1.6A will no longer run stable at 2560MHz. Instead, you may have to clock it down to 2400MHz. Big deal. The chance of a P4 processor, with increased voltage and adequate cooling, completely failing in several years is about as close to 0% as you can get.
