Voltmodded my card to 1.36v so far testing at 850mhz. 850 was my only ever aim since 100mhz on the core is not to be sniffed at.

What's the max reasonable voltage worth putting through these cards before OVP kicks in?

I've seen 1.4v banded about a lot?

the GPU core temps are fine at 65c load with the extra voltage, VRM temps are hot as usual but only ever excessively hot when running something like furmark which stresses GPU above and beyond of what they are ever expected of.
 
gurusan may have been running a 4870 volt modded card, might have been a 4850 recently. Could give him a shout via trust.
