Hi all! I am intending to overclock my back-up PC video card (It’s a MSI 9800 PRO). Perhaps, in next months, I will can to buy a better one, but, for the time being, would be good if I could to extract, from it, some more boost… I have read about video card OC in some forums, and I decided to try ATI Tool (V. 0.24), in order to find the “limits” of Core & Mem of my VC. As an information, the default speed of my MSI 9800PRO is: Core = 380 ; Memory = 340 (680) After running this utility, I got it : Max Core (No Artifacts) = 450 [with DEFAULT Mem] Max Mem (No Artifacts) = 402 [with DEFAULT Core] Well, I know that, if I increase the Core speed, I will not can to reach that “Max Mem”, and vice versa, because when we raise the two parameters together, they push the vc a lot! And, as this 9800PRO do not have temp sensor, I cannot control its temps, what is not good. So, the big question is: which parameter should have (at least, in theory), the better impact to FPS? Knowing that: 1) I am an occasional gamer, never play for many hours. 2) I ONLY play racing simulators, as, for instance, GT Legends, FIA GTR, Live for Speed and Richard Burns Rally. 3) I got used to apply the following eye-candies: 4xAA & 8xAF. 4) I do not intend to buy some better cooler solution for my MSI 9800PRO; its stock heatsink is huge and it is good, according to some reviews. 5) I want to make a safe OC, not going to the real “limit”. If I will know which of these 02 parameters could give me some better results, I could push more it than the other, to have a good final result. PS: Sorry, I am a newbie concerning to OC, but, should I to use the option Scan for Artifacts ONLY after that I define these 02 parameters… right? Is there some danger of damage, using this option, if I set, for example, the parameters as Core = 430 & Mem = 370 (740)?. What do this program make when, in this specific option (Scan for artifacts), it find some of them? Does it manage to decrease some (or all) of these parameters, until that it reach the stability? Well, that’s it… Thanks in advance for any help / tip!
