Bank 0/1, 2/3, 4/5 DRAM Timing

The system board designer must select the proper value for these fields, according to the specifications of the installed DRAM chips. Turbo mode reduces CAS access time by 1 clock tick.

SDRAM Cycle Length

This field sets the CAS latency timing.

DRAM Clock

Allows you to set the memory clock speed to either 66MHz or equal to the CPU clock speed, depending on your memory speed.
