This particular chip has not seen 4GHz even under water. vcore is 1.50 at 255FSB. I think Vcore would have to be 1.65 or 1.70 to get 3.8GHz and thats a bit much for air but I may try

My 2.8E@3.91 would easily make 4.0 GHz with water and probably 4.2 with phase-change cooling. As I'm doing 3.91 already at 1.50 volt, I also don't think it would not need 1.65 to get just 90 MHz more. It's simply a matter of better cooling.

But I agree: anything above 1.60 will probably kill such a CPU sooner than later. It's tempting though because Prescott responds so nicely to additional voltage.

I was speakimg in regards to this particular chip. Not all of them need the same vcore to obtain any given speed. Good O/C you have there. Be proud.

I disagree. Your cpu is exceptional. Others are not getting what you have at 1.5. Most are applying 1.6 or more to get where you are at....

I don't disagree It's anyway not stable (as already mentioned) to benchmark the system. And I would never say that this is what the "average" 2.8E user can expect. But it shows that it is possible to boot with an aircooled 2.8E at 1.50 volt into Windows XP - if you are lucky.

Yeah, but you're the GREAT Chainbolt!

Prescott Overclock results

Just wanted to share my results w/prescott overclocking. I have 2.8E and it runs stable at 3.5Gh. But my computer runs faster when I set it to 3.4gh because then memory runs stable at 1:1 ratio. I use Thermaltake vulcano 12 w/auto speed control to cool it. Idle temp is about ~40C and load is about 50C. I monitor and log temps with asus probe and the highest i've ever seen was 51C.

Thats a good overclock on air! Congratulations!!

I can get my 2.8E to 3.7 stable with Water cooling. Temps were not much lower that what you have even under water.

Always best to do 1:1 if possible. I wish I could find a CPU that could keep up with my memory as I have yet to find it's top end.

Time to go board up whats left of the house and get out of dodge.....Jeanne is almost here and it's going to be nasty! My next post may be on dialup from my laptop because I may not have a home to come back to but at least I'll have my family with me and safe!

To all my Central to Northern Florida buds......Stay Safe!

I have the same mb and memory as you but I can only get my 2.8e to 3.56ghz 255fsb 1:1 stable. Windows will boot up to 3.7 but prime95 fails. I'm also on water and getting 41 celcius idle and 45 celcius load with case temp of 30. bios version 1017. May I ask you what bios settings you have yours at?

I have a P4C800E-D with a Zalman 7000. The case is an Antec Sonata with twin 120mm case fans.

I was running a Northwood 2.8 @ 3.2 and switched to a Prescott 3.2.

I've only experimented briefly last night but getting to 3.6 was a no brainer. I used a Vcore of 1.4.

My Northwood used to run at 26 at idle and 50 at load. The Prescott idles at about 35-40 but at load it seems to stay at 55.

All this talk about Prescott needing water seems to be old baggage. In my experience it isn't radically different than Northwood under a Prime torture test.

I've also have a pretty quiet system. The Zalman runs at about 2200 rpm and the twin 120mm case fans are at about 1500 rpm.



Tonight I'm going to try and get to 3.7 by uping the Vcore to 1.5v.
