Just an update from me:

Powercolor 4830 now running 900Mhz on the core, up from 625 Mhz default.

1.5v hardmod, watercooling.

43'C load temps.



Wondering what to limit core voltage to - they are 55nm, right? I usually figure default voltage + 20% is pretty 'safe'. The 45nm Core2's are generally considered safe at 1.45v, so I wonder if these 55nm chips would be OK to 1.6v...

You know I want to hit 1Ghz on this cheap card, although I don't think even 1.6v would do that - I'm seeing only about 30Mhz increase now with each 50mV... so that puts me around 950Mhz @ 1.6v...
