2500k Owners- What is your Max O/C before a lot of extra voltage needed?

[Kenmitch]

I must have already wiped my 2500k data file as all I can find is images from 4.5ghz and up.

I think the first large bump was going from 4.4 to 4.5ghz but I'm unsure as it was 2 cpu's ago already and I find no images of the baby overclocks.

4.5ghz 1.32v
4.6ghz 1.34v
4.7ghz 1.38v <-- larger bump
4.8ghz 1.43v <-- larger bump
4.9ghz 1.45v
5.0ghz 1.48v

I discovered last night that from 4.6 to 4.7 I require a huge bump in voltage.

I seem to be perfectly fine running 4.6GHz @ 1.35v. I need 1.41v to get Stable @ 4.7GHz. Odd.
