Re: How to O/C your 4850146;s properly = Performance Only
Pretty sure ATI Tool hasn't been updated to support the 4800s yet. What I did was use CCC overdrive which got me up to 690/1183. I then ran Furmark and got artifacts so I kept dropping the memory down until they stopped. Ended up at 690/1135. Since you can't run the CCC at all I would just start at 650/1100 and run Furmark. Then move the core up in 5-10 Mhz increments until you see artifacts and do the same for the memory.

I use this tool:
»www.techpowerup.com/downloads/Tw···ATITool/ 
What I like best about it is it has two buttons that say "find max core" and "find max mem". Those move the sliders up a bit at a time and testing along the way for stability. |

| What are you guys using to O/C your 4850's/4xxx? CCC for me crashes all the time whenever I use overdrive. What do you guys prefer using, CCC or just the Catalyst Drivers and a third part application to over clock? I'm using the latest Cat Drivers 8.7 from AMD with a 500 Watt PSU. I mostly play COD4 and sometimes GOW. |
