Wheres the P4E's overclocking?

Title says it all. My brother is having me build him a new computer. But I have not been in the OC'ing arena for a long while. How do the P4E's fare out? I am thinking of a 2.8E for him, but it does not seem people are OC'ing the Prescotts... other than the 533 versions.

---editted to add---

Does the SP-94 mount to CPU core properly if I were to remove the IHS? I have not heard of anyone doing a review like that anywhere...
 
From what I've heard some of them overclock pretty well, but heat is of a huge concern. You will need very good cooling. I would stick with the 2.8C...it's a great overclocker BTW. Mine does 3.5 ghz @ stock voltages. 🙂
 
The prescott is not for the novice overclocker. It needs some hardcore cooling, if you aim for the some good O/C results. In otherwords don't bother unless your into water or phase. The northwoods are sweet as wine reaching 3.5 on stock vCore frequently.

The best alternative though is A64 if you're a gamer. They run cool, the 1mb CG steppings will OC to 2500 and at that speed they put a whoopin on p4's.
 
Cooling should not be that much of a problem. He already has a SP-94 and we live in Alaska. House ambient temps are around 62º-72º F during summer as we generally do not run heating. During winter the temps are set to 72º, it is hard to tell actual temps though.

He is not a gamer... well every now and the he will play KOTOR or BF, about maybe once a week or so. His main thing is DivX and MP3 encoding.
I do a mix of both, but the computer is not for me.
 
Alright.

One last ?, do OEM's or Retail OC better? Back b4 I killed my 2.53 CPU be removing the IHS (a proceedure I performed many of times with success, I just happened to sneeze and jerk doing mine). But the OEM's with mVid put all retail CPU's to shame. Is that still the case? A OEM prescott costs less than your $180... then again so does a OEM C
 
That's an awesome overclcoking motherboard (the best maybe?) and I would get retail mearly for the 3yr warranty and a decent HSF included.

The northwood isn't faster past 3.6ghz... So if you could take a prescott 2.8 and get it up another 1000mhz, it would rock the house.
 
Hardocp has gotten a 900mhz o/c on a 2.4 prescott with stock volatge 😉

Another site called madshrimp(I think) has gotten a 900mhz o/c out of a 2.8E and got it up to 4.4ghz with exotic cooling.

You forgot to mention it was not stable.:laugh: Not only that the 2.4s scale better with no HT and smaller die.
 
Uhmmm even Anandtech had a 3.2E running at 3.7Ghz with default voltage on air cooling.

Quote from the article :
"An effortless overclock gave us 3.72GHz; we could POST at 4GHz but we didn?t want to showcase what was ultimately possible with Prescott, rather what was easily attainable without increasing voltages. "

I've had everyone tell me to buy a 3.0C and overclock it, but I really don't think thats right. I personally, at the end of this month will pickup a Prescott CPU, and a Zalman cooler and give it a whirl. Everyone who'se actually TRIED -and actually owns a Prescott- says they are pretty decent overclockers, and once past the 3.6Ghz mark, they pick up where the C's left off.

Hotter yes, but nothing that will make them run unreliably. Just buy a good solid cooler 🙂
 
yeah the current prescott steppings seem to be a lot better than the ones that were being sold the first week or three

on water my prescott don't like to hold 3.5ghz let alone 3.7+
althought i did get it to boot at 3.9ghz before my bios got corrupted (on water)

would you mind backing this up? I remember seeing I forget where two 4ghz p4s one prescott and one northwood the northwood was faster
 
Well, it seems I should be getting a Prescott for him then.

I am not going to be doing it on his computer, but eventually I will be upgrading again. Does anybody know if the SP-94 cooler seats properly on the core if I were to remove the IHS? Or should I stick with my Swifty MCX as I know it will properly mount on a IHSless CPU.
