I have yet another overclocking report for you guys today. A reader comment on my original GeForce 2 Overclocking Experiment suggested that overclocking the video card core had a greater effect when the AGP bus was also overclocked.
Curious, I decided to run the same GeForce 2 overclocking tests again with an overclocked AGP bus.
Word of warning
Before we start, I should warn our readers about overclocking the video card's memory. One of our readers wrote in with his overclocking experience:
You might want to mention the fact that overclocking your video card runs the risk
of blowing the memory. My TNT2 Ultra that previously had the memory
clocked to 200mhz (183 is default) started showing strange screen artifacts.
Eventually, it would show them at default speeds, and now to avoid them I
have to underclock the card below factory defaults. This blows.
I have since replaced it with a GeForce GTS, and will not be overclocking my
video cards any more.
Video card memory is especially susceptible to overclocking damage. Even if overclocked memory seems stable at first, it may fail after extended use. Here in the office, we have a GeForce 256 SDR card that displays artifacts with the default memory settings, and we're pretty sure overclocking killed it. With that said, let's move on to the tests!
