Well I have one (e4500, SLA95) and I have it currently OC-ed to 3GHz with an 375MHz FSB (375x8). That with a Vcore of about 1,3V (1,292 / 1,280 with Vdroop under orthos). All other voltages are stock. Temperatures are roughly 50 degrees celcius under orthos (have a Scythe Mine Sandwich rev B) for the CPU, 38 steady for the motherboard (gigabyte EP45-DS3R). Memory currently clocked at 900MHz (timings: 4-4-4-12) @ 1.94V (dunno if it needs that though, mobo put it there stock ) from 800MHz stock. Runs stable like this (over 3 hours strait with orthos no errors). Thing is I know my chip works perfectly fine with an FSB up to 450MHz (tried 450x6) and the memory works up until 950 at least with the same timings stable (no voltage differences with the above mentioned). Thing is that I can;t seem to get the chip stable when I increase the core clock over 3GHz (nearly instant orthos error: after 20 seconds or so when at 3.1GHz). I don't want to add too much more Vcore voltage. All in all I'm wondering if changing any voltage other then Vcore would help to get a higher core clock. My FSB is pretty much stuck on 375 though as any higher will make me lower the memory clock (due to ratio fbs:mem). I think getting a higher FSB but lowering the memory will only be bad for performance. Also, anyone know how much lower life the chip will have if I go to say 1,35V? Also intel rates it up to 1,5V but that feels like a HELL of a lot to me .
