Why would you want to run a 5850 at 425mh/s?
You literally earn just a few cents more, but cut the card's effective lifespan to a few months. The stock frequency is 725, it wont last for long OC'ed to something such as 950mhz (or more).
I'd rather take the 0.02BTC less per day and have the card last longer at 380-400 mhash. If mining ever becomes unprofitable you can sell those cards even a year down the road.
Maybe people fail to realize warranty doesn't cover overclocking and volting

Ye I completely agree, besides those last 5-10% ppl get out of their 5850 cards beyond 350-360 MH/s almost doesn't even pay for itself, since they more often than not require so high voltage that the extra power draw almost eats up the extra BTC generated, ppl need to consider that increasing the frequency of a card (without touching the voltage) is a linear increase in power consumption while upping the voltage increases it exponentially. However saying that any 58xx core is perfectly safe running 24/7 for months/years with anything below 1.165V (5870 stock voltage) as long as they are properly cooled, the problem comes to the VRMs since they mostly have under dimensioned cooling and on some non reference cards you cant even find out at what temperature they are running. Just cause your core temp is at a healthy sub 75C level doesn't mean the VRMs aren't being toasted and will be the first part to fail. As a personal rule I never bother to take the cards further than they will do on stock voltage just cause of the diminishing returns.
Yes, I'm worried about my VRM's. I don't know how to find their temperature so they could be frying as we speak.
Honestly, I'm just seeing how far my card will go (and enjoying trying to keep ahead of the reference 5850 guys) while I await the power meter that I ordered.
