my specs are AMD Athlon 2100 1.6 ghz, 512MB PC 2700 RAM, 128MB Geforce 4, and Asus A7V333. I wanted to upgrade to at least 2ghz, but can I go faster? I don't know what to do for the following in the system setup CPU Frequency multiple CPU/PCI freq CPU memory frequency ratio CPU Vcore setting System performance. should I just leave these and change CPU speed? I'm not worried about overheating damaging my CPU because it always shuts down if it gets too hot. please get back to me with any advice, thanks!
