Advanced Chipset Features
AGP Aperture Size
The field selects the size of the Accelerated Graphics Port (AGP) aperture.
Aperture is a portion of the PCI memory address range dedicated for graphics
memory address space. Host cycles that hit the aperture range are forwarded
to the AGP without any translation. Settings: 4MB, 8MB, 16MB, 32MB, 64MB,
128MB, 256MB.
DRAM CAS# Latency
The field controls the CAS latency, which determines the timing delay before
DRAM starts a read command after receiving it. Setting options: By SPD, 3T,
2.5T, 2T. 2T increases system performance whle 3T provides more stable
system performance. Setting to By SPD enables DRAM CAS# Latency
automatically to be determined by BIOS based on the configurations on the
SPD (Serial Presence Detect) EEPROM on the DRAM module.
Note: Change these settings only if you are familiar with the chipset.
