Now, my grandmother's computer has a NVidia Geforce FX5200 AGP Graphics card. The original settings were: Core - 250mHZ Memory - 400mHZ. I clicked "Detect Optimal Frequenices" and the OC results came out to this: Core - 264mHZ Memory - 430mHZ. So far, no problems have occured. Is this a safe OC, or should I return everything to normal and use the tried-and-true method of OCing? For a little extra info, this Comp comes with an Antec Smartpower 500W PSU. The rest is in my profile under System #2.
