System Memory
System memory is necessary to operate the Tigercat
system board. The Tigercat has four 3.3V unbuffered
64/72-bit, 168-pin DIMM sockets for a maximum of 1GB
of EDO memory and 512MB of SDRAM memory. This
section list the rules for adding memory to the Tigercat,
give some examples of common memory configurations
and show how to physically install the memory.
Adding Memory
The following is a list of rules to follow when installing
DIMMs. If you follow these rules, your upgrade should be
trouble-free:
❏
Use 10ns or faster SDRAM or 60ns or faster EDO
DIMMs.
❏
DIMM memory modules support EDO and SDRAM
(unbuffered) memory types.
❏
Singled-sided and double-sided memory modules are
supported.
❏
Different memory types and sizes in separate banks
will cause the performance of the memory to run at
the speed of the slowest RAM installed, and/or cause
operating system stability problems.
For long
term
reliability,
Micronics
recom-
mends
using
DIMMs with
gold-plated
contacts.
The use of
tin-plated
contacts
may conflict
with the
gold alloy
on the
DIMM
socket.
