Ok i just bought sapphier 4850 GDDR4 yesterday..
Stock speed at 650/1100

With no voltage tweak the highest clock i got with 3dmark vantage BUT not stable when playing crysis :

720/1130


DEFAULT CLOCK





@720/1130 normal oc





Quite good eh? maybe it can go more with voltage tweak AND heatsink for ram coz THERES NO HS FOR RAM S@#$

It seem like i cant oc ram at all, stable clock for crysis just at 680/1100... >.<



Edited : New stable clock
