Agp Appeture Size

[Livy]

should i set this to the size of the memory on my agp card? the manual doesnt have much bios options in it.

AGP Accelerated Graphics Port. You don't have to coz your CPU will adjust the necessary default of your card.

That second link is the most thorough explanation of BIOS settings that I've run across so far.
It'll help you make decisions on a lot of the more obscure BIOS options.

Very interesting, clocker.

I have some more reading to do. :)

Clocker, although well meant, your first link points to a site which (along with many others) misunderstands the question.

AGP aperture size is nothing to do with the amount of memory used for mapping or anything else. That is controlled completely by the drivers and uses conventional memory.

The AGP aperture size is the size of the interface used to communicate with the AGP card. It is not associated with real memory (if you look at the memory ranges used in the device's resource details, you will see that they are way outside conventional memory ranges).

In some ways, it is similar to the memory ranges used by some early high performance cards when the memory address had to be below 16MB. There was a necessity to open a memory hole for these cards to use. However, the only reason for the current setting of memory size is to determine how much resource should be used (remembering that more resource means more resource management).
