This week TechARP tells all about the DRAM Ratio (CPU: DRAM) BIOS setting, you can learn about it over here.
The choice of options in this BIOS feature depends entirely on the setting of the DRAM Ratio H/W Strap or N/B Strap CPU As BIOS feature.

  • When DRAM Ratio H/W Strap has been set to Low, the available options are 1:1 and 3:4.
  • When DRAM Ratio H/W Strap has been set to High, the available options are 1:1 and 4:5.
  • When N/B Strap CPU As has been set to PSB800, the available options are 1:1, 3.2 and 5:4.
  • When N/B Strap CPU As has been set to PSB533, the available options are 1:1 and 4:5.
  • When N/B Strap CPU As has been set to PSB400, the only available option is 3:4.

    The options of 1:1, 3:2, 3:4 and 4:5 refer to the available CPU-to-DRAM (or CPU: DRAM) ratios.
