HD4850 to go past 700MHz core Tags: Graphics Cards Core Cooling Overclocking Last response: February 9, 2009 3:16 AM in Overclocking Share CoreOxide January 17, 2009 12:42:39 PM heya, Got an AC Twin Turbo cooler for my card, now it's nice and cool at 700\1170. Now, I want to push the core further, I've seen around the web people who get 800-850. AMD GPU Clock Tool won't work for me, when I try setting new clocks it says "SetClock failed, please check your device configuration". Is there any other tool for OCing the card? or maybe a solution for the problem? Thanks, Alex More about : hd4850 past 700mhz core richardscott a b K Overclocking January 17, 2009 2:20:30 PM yea getting 800-850 core is only on ln2 not air unless you have volt modded it. CoreOxide January 17, 2009 3:07:49 PM I think I can get at least 750 core, but the problem is CCC won't let me get past 700, and AMD GPU Clock Tool doesn't work for me...
