need help overclocking

i have a ati radeon 9250 256mb graphics card with the radeon omega drivers catalyst 6.05 (since that is the highest i can get from guru3d or omegadrivers....i want to know how i can overclock my graphics card so it can have a better performance and smoother gameplay on call of duty 2 because im getting realy bad lag when it comes to fog and smoke in the game...anyways my computer is a dell dimension 3000...pretty old, but i added 1 gb of ram and a graphics card...so please help and thanks....plus, i dont want to overheat my computer if its possible....because this is the only computer i have...

 

ATItool would be your best bet. I believe the 9200 and 9600 series are overclock locked but the omaga drivers and ATItool are able to get around the lock. Also have you tried disabling the fog/smoke in COD2? Even overclocked a 9200 is to weak for COD2 (IMO) perhaps a newer/faster card is in order ?

 

i tried disabling the fog and smoke on the game, but it seems to be a cheat on the game because i play multiplayer a lot...but i just want to overclock safely without over doing it

 

If you use ATItool and test for artifacts at your overclocked speeds to be sure its stable it will be fine.

 

with my ati radeon 9250, will i see a big difference after the overclocking?

 

Depends on the rest of your system specs.

 

well i want to know what is the best i can put on the memory and the core....i ahve it on 240 and 200, what should i raise it to?

 

There isnt one universal setting, every single card is unique. Do what ACE said and test it with ATItool at each step; start with either the core or the memory then increase it in small increments, testing at each step. Once you find the max OC then move on to the other (i usually start with the core then do the memory just because the core is generally tougher to tweak) and do the same thing.

You can measure the performance increase by running a program like 3dmark before and after the OC. there is also a nifty little program called video card stability test which is nice (you can tell they took a long time trying to figure out the name lol) http://freestone-group.com/video-card-stability-test.htm

run it before the OC and after to see how it does. dont forget to keep an eye on ur temps! you may want to upgrade the cooler but with that card it may not be worth it. its up to u though
