RAS to CAS

Use this feature to set the number of cycles for a timing delay between the CAS and RAS strobe signals, used when DRAM is written to, read from or refreshed. Fast speed offers faster performance while slow speed offers more stable performance. Settings: 3T, 2T, Auto.

Burst Length

This setting allows you to set the size of Burst-Length for DRAM. Bursting feature is a technique that DRAM itself predicts the address of the next memory location to be accessed after the first address is accessed. To use the feature, you need to define the burst length, which is the actual length of burst plus the starting address and allows internal address counter to properly generate the next memory location. The bigger the size, the faster the DRAM performance. Settings: Auto, 4, 8.

DRAMCommandRate

This setting controls the SDRAM command rate. Selecting 1T allows SDRAM signal controller to run at 1 clock cycle rate. Selecting 2T makes SDRAM signal controller run at 2 clock cycle rate. 1T is faster than 2T. Setting options: 2T, 1T.

Current Host (FSB) Clock/DRAM Frequency

These features show the current host clock and DRAM clock frequency. (read only)
