Memory error checking is supported by parity check. To use parity check you
need 72 bit DIMM (64+8 bit parity), which are automatically detected by BIOS.
Warning: The driving capability of new generation chipset is
limited because the lack of memory buffer (to improve
performance). This makes DRAM chip count an important
factor to be taking into consideration when you install DIMM.
Unfortunately, there is no way that BIOS can identified the
correct chip count, you need to calculate the chip count by
yourself. The simple rule is: By visual inspection, use only
DIMM which is less than 16 chips.
Tip: The parity mode uses 1 parity bit for each byte, normally it
is even parity mode, that is, each time the memory data is
updated, parity bit will be adjusted to have even count "1" for
each byte. When next time, if memory is read with odd
number of "1", the parity error is occurred and this is called
single bit error detection.
