  • Page 54: Dram Timing

    DRAM Settings The first chipset settings deal with CPU access to dynamic random access memory (DRAM). The default timings have been carefully chosen and should only be altered if data is being lost. Such a scenario might well occur if your system had mixed speed DRAM chips installed so that greater delays may be required to preserve the integrity of the da ta held in the slower memory chips.

  • Page 55: Dram R/W Leadoff Timing

    DRAM R/W Leadoff Timing This sets the number of CPU clocks allowed before reads and writes to DRAM are performed. Seven clocks leadoff for reads and six clocks leadoff for writes. Six clocks leadoff for reads and five clocks leadoff for writes. 7/6 Leadoff timing is the default.
  • Page 56 DRAM Write Burst Timing This sets the timing for burst mode writes from DRAM. Burst read and write requests are generated by the CPU in four separate parts. The first part provides the location within the DRAM where the read or write is to take place while the remaining three parts provide the actual data.
