I have an Akasa AK 824cu cooler and an XP2200 (can't remember flavour but I have to assume pally). MBM5 is telling me 59-60deg idle. Run up a reasonably modern game and bang it falls over after 5-10mins depending on the game and ambient temperature. BF1942 is BSOD, Mercs4 is CTD. MBM5 at this point is showing a nasty 66 or even 67deg. SETi is another matter all together. It dies at the beginning of the second unit...pass.
Moby-Dick lends me an SLK-800 and 80mm ooomillion rpm mini-vortex generating Delta. Side of case off. Feet now have personnal cooler.
Result is stable SETi, and games doing what games do best. MBM5 is still claiming 56-57deg but this time when SETi and co are all in full swing.
The question is this:
Will a mad hunt for a Bartonesque XP2500 allow me to reallocate the glowing blue Akasa to cooling duties, or will I still need the services of the almightly Delta, SLK in tow?

To get such high temps is very strange fo an XP2200+ which surely is a TbredA, AFAIK all XP2200+ are TbredA. It might not be a true XP2200+, poosibly an o/c'ed Pally which would account for massive temps. TbredB and Barton don't run that much cooler than TbredA but they do o/c MUCH better, Pally's are the REALLY hot ones and you're lucky to get one to XP2200+ speed if that is the case. I would check your case for a sign it's the heat culprit (or part of), it should have good ventilation and case fan mounts (fans located optimally and piinting correct way). The gfx card can be the next big heat producer, a passively cooled one often gives off more heat, esp bad as it rises directly to where the CPU is located.
Anyway you should try an XP2500+ as that way you don't have to battel to verify TbredB as you'll always get Barton and stepping codes etc make no real diff for Barton. At stock it's a cool runner esp if you undervolt it, I'd certainly expect your Akasa to be up to it (without actually checking its stats). If you do get probs then as said try the SLK with a quiet or adjustable fan (like Smart Fan II?) as that should certainly cope ... you could also 7V mod or add a controller to that screaming Delta.
To o/c the XP2500+ all you ideally need is a mobo supporting 400FSB or 333FSB with multiplier control. Of course for 333FSB you'd want PC2700+ and for 400FSB PC3200+.

Regarding stepping codes AGOGA and AGOIA, they are both TbredA not Pally, check the quote you give and you'll see I'm addressing Pally CPUs which are always locked and notoriuosly hot runners. Just because you could get an XP1600+ to XP2100+ does not mean it's a good o/c nowadays esp when you consider prices, TbredB and Barton offerings. What you say about the AGOGA and AGOIA steppings illustrates just how poor the TbredA are at o/c'ing as they rarely can do 2.0ghz (XP2400+), the 8 layer design simply has too much cross-talk.
