The driving capability of new generation chipset is limited
due to the lack of a memory buffer (to improve
performance). This makes DRAM chip count an important
factor to take into consideration when you install DIMMs.
Unfortunately, there is no way that the BIOS can identify
the correct chip count; you need to calculate the chip count
by yourself. The simple rule is:
.
To identify single-side or double-side DIMM, check golden
finger pin 114 and pin 129. If there are traces connected to
pin 114 and pin 129, the DIMM is probably double side;
otherwise, it is single-side.
To identify 2-clock and 4-clock DIMM, you may check if
there are traces connected to the golden finger pins 79 and
163 of the SDRAM. If there are traces, the SDRAM is
probably 4-clock; otherwise, it is 2-clock.
