M6DPi System Board Manual

Chapter 3: Installing the M6DPi

System Memory

System memory is necessary to operate the M6DPi sys-

tem board. The M6DPi supports DIMM modules for the

main memory. There are four 168-pin 3.3V unbuffered

DIMM sockets for a maximum of 1 Gbyte of memory.

Each socket provides a 64/72-bit wide data path.

The M6DPi also supports SIMM modules for the i960

processor. There are two 72-pin SIMM sockets for a

maximum of 128MB of memory. Each socket provides a

32/36-bit wide data path. These sockets are needed only

when using the i960 processor.

Support is provided for EDO and FPM DRAM memory.

This section lists the rules for adding memory to the

M6DPi, give some examples of common memory con-

figurations and show how to physically install the memory.

Adding Memory

The following is a list of rules to follow when upgrading

DIMMs and SIMMs. If you follow these rules, your

upgrade should be trouble-free:

❏ Use 70ns or faster DIMMs and SIMMs. NOTE: For

long term reliability, Micronics recommends using DIMMs

with gold-plated contacts and SIMMs with tin-plated

contacts.

❏ Both SIMM and DIMM (unbuffered) memory mod-

ules support FPM and EDO memory types.

❏ Singled-sided and double-sided memory modules

supported.

❏ Use the same type and size of memory for every bank.

Different memory types and sizes in separate banks

will cause performance of the memory to run at the

speed of the slowest RAM installed.
