Well, up and running with the Asus and the Prescott. No problems so far. I have no idea what to say as far as my issue goes. It is just all working now with no issues. I booted into windows at 260 fsb, but I will have to get back to this testing later on... I have to get off for awhile and get some things done.

PJ I was reading this thread like a suspensful(sp?) novel haha. Good stuff, Ive been waiting for someone who has the balls to buy a Prescott to see if i want one 😀 Does your canterwood board read the vcore right? And damned nice job keep us posted, we are all excited to see what those chips pull out next 😉

Hehe.... Well guys, it is Sunday, and I really am a Pastor, and you know we only work one day a week, and this is it!

Unfortunately from what I've read of the retail chips, I'm beginning to think that the Prescott 2.8 chips won't give very good overclocking results... If people aren't able to overclock the 2.8 by more than 33% then they won't hit the inflection point (3.8 or so) where the same chip-for-chip clock speed gives better results for the Prescott over the Northwood. I think I read over on overclockers.com that perhaps these first chips were rushed out and won't be as good as later steppings. So, it looks like a 3.2 GHz Prescott may be the chip to buy when it becomes available.

Hope it works out well for ya!! :beer:..i got the same board and cooling but i'll wait another week or so before i order a 3.0E ..If i can do 3.8-4.0 with air then im happy 😀 . The Asus P4C800E-DX is one of the few boards that with a bios update fully supports Prescott (bios 1014) and is one of the fastest Canterwood boards (if not the fastest) I've seen benches where its even faster then Intel's own mobos with the Prescott cpu. BUT the Intel mobos produced/consumed less heat wattage!

H|OCP could not get their prescott to run on a p4c800.

Perhaps it was a bad chip? Most review sites prefer the Asus mobos for the Prescott because of the bios update not sure about the Abit though have they released a bios update?

Not a bad chip...

Our Asus P4P800 and P4C800 motherboards would not operate with our 2.8GHz Prescott CPU. Checking the the Asus website for BIOS updates left us high and dry. Interestingly enough, the P4P800S that is based on the single memory channel chipset, the i848, worked just fine with our Prescott CPU at stock speeds. No BIOS update was present nor needed. We did not use this board for overclocking as it is not really marketed for that usage.

Oh..i just checked the review at H|OCP intresting read! Could it have been bad mobos then? I mean it's the first time i read that a P4C800 didnt work with Prescott most reviewer have been using asusboards afaik (P4C800E).

PJ reported an issue with the ASUS/Prescott in this thread. From the looks of things, it appears that there may be trouble ahead for Prescott/Canterwood.... I would speculate that the MOSFETs are not quite up to the task...

I think i will hold on to my Prescott order a little bit longer then..last thing i want is a chip that dosent work with my mobo 🙁
 
This is problematic that HardOCP's chips would not work with Asus boards. In a word - it sucks. Why? Because it means that not all Asus boards will run it well - or you could end up with a smoking motherboard. Urgh.

I think the safe thing to do is not buy a socket 478 prescott and wait until the waffle socket chips arrive.
 
I've seen several reviewers successfully use the P4C800-E, & also saw the |H| review, where the Asus didn't work. This smells to me, almost like a mobo Bios, or cpu VID issue. On thier site, Asus still claims the P4C800-E supports Prescott, when selecting Hot Product/Motherboard/Prescott CPU Support HERE, and also HERE.

But my strongest thought is: I wonder if this could have anything to do w/the release of Ver 2.0 of this board, not too long back. I don't recall seeing mobo version #'s in the reviews, IIRC.

I do mainly DC, using barebones P4C/P4P800 systems. I really want to see how the P4E's 1M L2 cache works w/2 - SETI CLI's. If I DO decide to give a Pressie a go, I'm definitely goin' to toss it in a "stripped down" Ver 2.x P4P800 sys, & NOT even consider my main rig (in sig), ATM.
 
PJ: Please include temp readings of the MOSFETs and caps on either/both the DFI and ASUS.

At this point in time, I am inclined to go along with Ed Stroligo in This Article:
If you think the MOSFETs and capacitors on your motherboard can take care of themselves without serious cooling, you are certainly not serious.

Actually, there's a simpler test to determine whether or not you're serious enough. Are you ready and willing to lose it? CPU and/or mobo?

If the answer is "No," you have no business buying this stuff.

No, didn't give up, just had a paper to write last night, and I had a church member die (I had been at the hospital since 3am yest morning. I was beat and needed some rest! Back to it this evening! And, I have my sp94 now too!

PJ
 
Ok all... I am testing again... got the Prescott on myAsus p4c800e and all is running fine. I installed a Thermalrigth sp-94 and my temps have decreased a little. I have yet to find the max temp, but my idle is 3-4*c lower than with the Zalman. I am using a Panaflo 92mm "M" fan.

Here is my latest work: 260fsb
 
I'll be very interested to see a benchmark comparison between the Northwood & the Prescott when both are clocked above 3.8GHz. Keep going!

What's interesting is that Hard|OCP couldn't get this board to work! They had great luck with the MSI board, maybe that's the one to try next if you have the opportunity.

Yes, I read that as well. I do not have the MSI, and i don't really plan on buying it just to test this chip. Maybe a DFI Infinity will come my way and I might try that, but for now, I am sticking with my old faithful. I thought I lost her the other day, but all is well as of now!
 
:Q now that's impressive PJ!!! do you feel it can go higher? how much headroom is left in there?

Really gr8 results!!! 🙂
