Highest stable clock for Northwood and Prescott?

Just got a Celeron D 320 (2.4GHz on 533FSB) and like many others, was able to run at 3.6GHz (800FSB) no problem. Seems to be stable all the was up to 3.96GHz (880). My Northwood P4/2.4B seems only able to do 3.2GHz stable and I wonder how my P4/2.4C might do? All with stock cooling and voltage. Wonder also what kind of volt leakage I'm having on the Celery.
 
So this Celery is pretty damn good for $75, eh? I see you have your Prescott up in the same range - any issues? What voltage? Rest of rig looks Kick Ass. Ever do any Distributed Computing, like SETI, FaD, or Folding@Home?
 
Running with Vcore of 1.48, had a lot of heat issues at first, but under control with water cooling. I run Seti, but it's running 24/7 on my other rig(3.2ES @3.6ghz). Celeron D's seem pretty decent, definatly got a nice OC on yours.
 
What's a 3.2ES? I haven't had to adjust vCore yet and using stock cooling. Wonder how high I could go with a setup like yours?
 
I happened to notice the other day that Microcenter was selling P4 Celly-Ds (sounds like "Sunny D", doesn't it? 🙂 ) for something like $70. After seeing that some of them clock as high as 3.8Ghz, and at that speed, perform similarly for some things as a P4 3.2EE, well, that's pretty amazing. I have a mobile P4 2.0Ghz Northwood right now that someone gave me, trying to get it to work in a desktop board, when OC'ed with FSB800, it should run at 2.4Ghz. Trying to decide if I should skip messing with the mobile Northy and just pick up a Celly-D 320 and roll with that, or what. The benches of that CPU's speed were more-or-less about even with a P4 2.4C in XBitLab's benchmarks/article. So I would be spending another almost $100 on a CPU that I don't really need, for the chance that it would be faster, but might also not OC at all and be the same. Are those Celly-D chips usually a sure OC, like the Celly 300A was back in the day? Kind of worried about the power/heat issues if I went with one of those, the mobo I got was that QDI 845PE 800Mhz board from Compgeeks, claims to support Prescott, but the two-phase VRMs look a bit wimpy, is the Celly-D significantly lower-powered than a P4 Northy? Or does it draw more power? Being Prescott-based, I fear the latter.

 
Prescott 3.0E for S478 89W, and Celeron D 2.4 73W. Hard to find Northwood stats, but Celeron D uses less than the P4 478, as you can see
 
If you are trying to get a max oc, why dont you just get a better heatsink. Celly voltage should be lower than a P4, because of lower base speeds.
