My E5200 (Costa Rica) does 3.7GHz (11.5 x 321) @ 1.360v (NB, FSB and PCI-e volts at stock, CAS4 RAM that require 'only' 2.0v @ 802MHz). Max FSB would be around 340MHz.
It's also stable at E8500 speeds 3.16GHz with stock volts (set to normal in bios): 9.5 x 333MHz, C1E and EIST enabled for lower power consumption and heat.
In my P35 DS3R BIOS I can set "Performance Mode: TURBO", this way I get ~125MHz more performance (based on SUPERPI 1M), still same vcore required.
Also, awesome to compare Everst Home 4.60's bench "CPU Queen", E5200/3.7GHz isn't far from E8400/3.98GHz (16767 when just tested on E8400) !
