Saphire 5850 Xtreme overvolting?

[brunoshady]

Does anyone tried to overvolt a saphire 5850, or a similar with or without bios flash?

I have some questions about it...

Tried it for myself. It works, but the GPU gets very hot (big cooling problem) and there is much(!) more power comsumption (watts per mhash/s). Only interesting for extreme gamers in my opinion, not for long-time mining, because of the high energy costs.
