Good luck identifying the RAM. We have been<br>
in the business over 25 years and cannot<br>
identify all RAM, since there is no standard.<br>
Each manufacturer will call them something<br>
different. Start by sorting according to<br>
pin configuration. Within pin configuration,<br>
sort according to chip count or density.<br>
Speed is usually the easiest. Most chips<br>
will have a -6, -7, -8 or -60, -70 or -80<br>
at the end of 1 of the number strings. This<br>
is the speed in nano second access time.<br>
The long number before this is the chip #.<br>
The only sure way to identify all modules<br>
is to first identify the manufacturer's<br>
logo on the chip, then reference the mfg.<br>
documentation to identify the chip. Then<br>
use this information to calculate the<br>
density of the module by adding-up the chips.<br>
Sometimes, we just set-up a slave machine<br>
and start plugging them in then reading the<br>
memory reported by the system. Usually, no<br>
harm can be done, unless you are dealing<br>
with some of the newer 168-pin chips which<br>
can operate at different voltage levels.
