Enabling AGP sidebanding didn't help at all but increasing the clock speeds really helped increase the 3DMark score, especially the increased memory speed.
In the end, the Go5200's performance improved by 22.64%.

Mother Nature	3.29 FPS	3.31 FPS	3.39 FPS	3.85 FPS	4.00 FPS

Significant improvements were only noticed in the Wings of Fury test, and then only with the increase in memory speed.
The increase in core speed and the AGP sideband support didn't do much at all.
In the end, the Go5200's performance improved by 22.84% in that test.

The increased core speed helped boost theGo5200's Vertex Shader and Pixel Shader 2.0 performance
while the Ragtroll test improved more with the memory boost.
