Memory Timings (Optimal)
This item allows you to set the Memory Timings. The following four items be-
come available when this item is set to Expert.
T(RAS) (7)
This item defines the timing delay for DRAM precharge.
T(RCD) (1)
This item defines the timing of the transition from RAS (row address strobe) to
CAS (column address strobe) as both rows and columns are separately ad-
dressed shortly after DRAM is refreshed.
T(RP) (1)
This item defines the numbers of cycles for RAS to be allowed to precharge.
CAS Latency (2.5)
This item defines the timing delay in clock cycles before SDRAM starts a read
command after receiving it.
FSB Spread Spectrum (0.50%)
This item allows you to set the FSB spread spectrum modulation.
AGP Spread Spectrum (0.50%)
This item allows you to set the AGP spread spectrum modulation.
AGP Aperture Size (MB) (128M)
The DRAM timing is controlled by the DRAM Timing Registers. The Timings
programmed into this register are dependent on the system design. Slower
rates may be required in certain system designs to support loose layouts or
slower memory.
AGP 8X Support (Enabled)
This item allows you to enable or disable AGP 8X Support.
AGP Fast Write Capability (Enabled)
This item enables an end sure to manually select the AGP output buffer driver
strength.
