When I overclock my system, I get into Windows fine, and it runs through a couple of hours of Folding@home as well as 3DMark03 and 3DMark01SE with no problems. In games, however, I usually get application crashes within 10 minutes of starting. Here's my current setup in BIOS during OC CPU: 200x11, 1.75 V RAM: 1:1 ratio, 2-3-3-7 Timings, 2.70 V Chipset: 2.70 V AGP: 66Mhz There are no PCI cards installed on my system. Windows XP SP1 and all the latest updates installed. Using Catalyst 4.1 Drivers with Overdrive enabled. PSU - Antec TruePower 480W The rest of the specs should be in my signature. Only time my games run stable is with stock speeds, but I kinda want to try and sync my FSB for the RAM to optimize my setup. My load temps during OC range from 49-54C depending on the ambient temp at the time. Any pointers?
