An answer please?

Can someone who really does know about AGP read synchronization and side-band addressing finally give me an answer?

Alot of people have found read sync in their BIOS, but no one has been able to explain to me what it does, and whether it effects performance or stability one way or the other.

What about side band addressing? I read somewhere this will allow your system RAM to use textures. But I thought that is what your AGP Aperture Window was for? I don't get it. Does your aperture size just create memory holes in your PCI addresses - and side banding will actually allow your system memory to store textures; instead of your VRAM?

Also, would it even be wise to enable side band if you have a 128MB card? I heard Doom 3 will only use 80MB for textures, and the DDR 266 standard for system memory is way out dated compared to current VRAM (500MHz on a GeForce 4 for example).

So what's the deal experts?
