Can AGP aperture size *physically* do damage?

[membreya]

I'm just wondering if setting the AGP aperture size will physically do any damage to your video card/motherboard?

no

All the setting does is allocate and reserve the selected amount of your main system's RAM for video processing just incase your video card's onboard memory runs out. So If you have a card with 128 MB's or over, chances are there is not a game in the world that would actually borrow your system's ram for video processing. Except maybe for D3 and Far Cry above 1600x1200 resolution.

No it doesn't even do that. All it does is reserve an access window in the machine's otherwise empty _address_ space (not memory space). The actual borrowing of system RAM is a dynamic process, done on demand; the graphics card can then use the "aperture" window as a collected view of the various borrowed spots in system RAM.

you would be suprised actually. the 128MB on the 6600GT really cripples its performance on farcry/doom3/halflife2 and most other recent games with AA/AF enabled at >12x10. thats why i got the 6800gt

It's more limited because of the 128bits memory bus than anything.
