I have a system with a Mach Speed P4MSD-800 Mobo with a Pheonix Award Bios, and a GeForce FX5200 256MB video card. I was poking around in bios today and I noticed in the "AGP & Bridge Control" section, the "AGP Aperture Size" setting is set to "[128M]". The card is recognized in windows as being a 256MB card. Should the bios setting actually be set to 256M instead or is this setting not related to the size of the onboard memory of the card? Would it make any difference to change this? Also, "AGP Fast write" and "AGP 3.0 Calibration Cycle" are disabled, should these actually be enabled? These settings were set automatically and I didnt change any to see what happens as I dont know what they are. All opinions on the matter are welcome.
