First of all, AGP Aperture memory will not be used until your video card's on-board memory is running low. That means it will usually not impact your gaming performance because developers are trying hard to not exceed the on-board memory limits.
The bigger your video memory, the smaller your Aperture Size could be. However with later games requiring more and more texture memory a good number seems to be 128MB Aperture Size for all cards with 64 MB to 256 MB Video RAM.
Setting the Aperture Size to HUGE values will not increase performance because this merely sets the maximum amount of physical memory that can be used. It only makes the GART Table bigger because every 4K page has its own entry, no matter if allocated or not.
Setting the Aperture Size to too small values could result in running out of available texture memory especially on a low-mem video card. It is also possible that developers make use of the GART's features by creating textures as 'non-local'.

looks like the memory is borked to me. if it was the core it would be coloured dots everywhere and freezing, time for a new card i recon.
It's funny - after being told constantly on many forums to RMA the card or re-install windows, someone clever clogs suggested to just turn off Write Combining in Display Properties > Settings > Advanced > Troubleshoot.
MAGIC, it works! (for the time being!). No artifacts and no system reboots. Give it a try if you're experiencing similar probs with older systems and SIS chipsets.
