Hi guys, I want to overclock my Grpahics card, Ati mobility radeon. I downloaded the ati gpu clock tool. It says my memory speed is approx 396 Mhz. I have a laptop (HP) and my question is should i overclock it and if yes by how much and upto how much should i go. Originally my cpu temperatures go to like 40 to 45 c. so if i overclock it a little more they should go up to like 50 to 55. Depending on my temperature i can set the defaults. My specs are: Hp Dv6-1238CA 4Gb ram 2.10 Ghz Dual core (Centrino Processor) Windows 7 OS 512 mb dedicated graphics. Core clock 500 mhz Has anyone ever had any experiences with overclocking GPUs (ati's) if so please reply to this thread !
