: thanks in advance,
Most PC's use memory with parity, however the parity check can be
disabled from the cmos setting and memory without parity will also work.
If you have a brand name computer you probably have memory with parity
is you bought your computer from an honest dealer you probably have memory
with parity, however there are some computer dealers that sell PC's with
memory without parity to save money, when this is the case they don't specify
the type of memory that comes with the PC, memory without parity is 10% to
When memory has parity and is the 72 pin type, it has 36 bits, 32 data and
4 for the parity, usually this means you have 2 different types of memory chips.
If you have a PC you should use memory with parity.
