To heck with the Prescott going back to a Northwood P4

[SilverBack]

Heat is the biggest factor. I have a 2.8E which does 3.5 easily enough, but it draws so much juice that the motherboard gets hot. ( IC7-G Max3 )
I decided to buy a 2.8C to put back in my machine.

 

[slag]

wanna sell that 2.8?

 

[SilverBack]

Sure, I got it from NewEgg on 2/10 for 185.
$100 sound Ok?

 

[myocardia]

Wouldn't it cost you less, and gain you more, if you just watercooled that Prescott?

 

[Cybercat]

Aren't they known as 2.8E's?

 

[SilverBack]

Yes 2.8e
And it is water cooled
My water system

I didn't complain about the CPU being to hot, but the motherboard. The capacitors get VERY hot when overclocking these chips.

 

[Cybercat]

Yeah, overclocking is generally not encouraged with the Prescotts, seeing as running them at stock speeds alone will put your capitors to extreme temperatures. Obviously current chipsets were never really meant to handle the Prescotts, although they are capable of it, conditions won't be improved until the next chipset is released.

pm me if you would so we can work out the details.

Thanks

Since the subject is P4 2.8E's.....bought a new one from Newegg and installed in system now running a 2.4b. System won't post ....system won't boot......

Any thought hear guy's .....Tried to reset bios to defaults........ still no luck :frown:

Should I RMA the thing or try a different board?

On mine it took a BIOS flash to a BETA release v14 on my IC7 Max3 before I installed the new cpu.
What motherboard are you using?

 

[Soggysocks]

Asus P4PE

 

[Soulkeeper]

definately worth 100 bucks

you want me to test it on a prommy?

still have my p4p800 lying around... need to sell that puppy soon and get some money!

The Asus P4PE spec shows
Front Side Bus
533/400 MHz

This board will not supoort the Prescott ever.
Prescotts are 800Mhz FSB cpu's

Never say never,there will be 2.4ghz prescott cpus , 533 fsb no HT.

Yeh but a 2.8E runs @ 533

 

[slag]

no, a 2.8e runs at 800 mhz fsb.

no 2.8b runs at 533 (i think thats right)

 

[jpetermann]

hehe... got it

 

[slag]

got what?

 

[LouPoir]

2.8e = 800FSB

About the Prescott cpu's

If you look on my web page I had bought two of the Prescott cpu's. To avoid any confusion I'm selling both.
I do have two offers right now.

@.8E's are supposed to backward compatible

 

[Ackmed]

I will buy it for $100... I would like to test it on my IC7 MAX3 with a Mach II on it. Currently my 3.0c is at 3.9gig, 260fsb. Interested to see how the 2.8E fairs. Might even trade CPU's.. if you add some cash.

The Prescott cpu's were designed with a higher wattage in mind than any 400/533 FSB motherboard when they developed.
The power restictions were high enough that only a few chipsets can handle the cpu.

A few of the chipsets were 875,865 and 848. (the intel ones)
The cpu wasn't designed to be backward compatible with any chipset made over a year ago. The motherboards simply can't do it.

If you want a Prescott you'll need to get another motherboard.
