e6300 is a 2m Conroe core (half cache disabled). e4300 is a native 2m cache core with supposed other minor differences. There seem to be numerous reports of e6300 and e6400 hitting over ~3.4ghz with air and water but almost no reports of e4300 hitting over 3.4ghz with many people topping out at 3.2ghz

Although it is possible that people are chickening out on making the jump to >400mhz FSB (3.6ghz with a 9x multi)...
 
I know, but people haven't been getting as high clocks even on water as on the conroes, which is why I'd pick the e6300 over the e4300, perhaps the e4400 will bring some improvement to that with a nice 10 mult

It does seem to clock higher, but you have to be able to hit 429mhz FSB just to get 3ghz out of an e6300 and that means a some pretty decent mobo and RAM choices. 3ghz with an e4300 seems achievable with almost any system you wanna slap it into.
 
ahh, so it's not a cpu issue, but that they just don't want to push the chip and don't change straps forcing a wall in overclocking

Possibly. If people start topping out at ~3.5ghz with e4400s then that would verify a FSB wall but would still require more testing to see if it's a CPU limitation or what. I don't know why an Allendale would top out at 355mhz FSB when Conroe can do over 500. But I also don't know why an Allendale would hit a FSB NB incuded FSB wall at ~355mhz when Conroe hits it at ~370mhz. I just don't feel like personally spending the money to find out but if anyone out there wants to bite the bullet and set their allendale to ~1.5v and ~415mhz FSB (with full multiplier) and see if it posts I'd be happy to let you tell me how it went :) Maybe we should recruit someone from the souther hemisphere to try it for us this summer if no one else has... an e4300 + stick of DDR2-900 capable ram out to be fairly cheap by then and Argentina will be nice and cold.
 
It's just a throwaway CPU (quad core in July) but I am expecting 3.2 out of the chip, any more will just be butter on top. I have a Scythe Ninja Rev. B so I think it should be doable. Anyway I should be able to pick the best chip out of five or so computers I'm building for others.
 
The Kentsfields do run hot, but the reason that they run hot enough to destroy heatsinks and other cooling apparatus is that they're able to be overclocked a fair amount. A Q6600 at the stock 2.40 GHz shouldn't run any hotter than an X2 6000+, in fact, it probably will run a tad cooler if the same heatsink is put on the 6000+ and the Q6600. The Q6600 shouldn't be anything to avoid as long as it remains at stock speeds.

The QX6700, Xeon X5355, QX6800, and Xeon X5365 are extremely hot-running CPUs, especially the 2.93 QX6800 and 3.00 GHz Xeon X5365. I'd wait on buying a quad until 45 nm Yorkfield parts ship if I wanted one over 2.4 GHz. Either that or wait for the Agena, <obligatory AMD delay bash> but at least we've seen the Yorkfield benched </obligatory AMD delay bash> 😀
