WARNING: Don't change the parameters inside the BIOS unless you fully understand the meanings and consequences.
Problem:
Motherboard (such as: ABIT NV7-S V2.0) is not displaying DDR400 at startup.
Solution:
The BIOS/CMOS may not be set correctly. Set the CPU FSB/DRAM ratio option in BIOS/CMOS to By SPD, if available.
If DDR400 is still not displayed, you can try manually adjusting the FSB/DRAM ratio. For example, if you change the setting to 4/6, the memory clock will be the processor FSB (Front Side Bus) clock divided by 4 and times 6. Refer to the table below.
