[comp.sys.sun] IPC Memory configurations

srm@unify.com (Steve Maraglia) (11/27/90)

I pulled the below posting for the IPC off comp.sys.sun a few months back.
We have ordered four IPC's and I'm trying to determine how much additional
third party memory to buy.  We would like to put 16MB in each system.

Q1. Is the below statement "memory must be added in increments of 4 SIMM
    modules at time" correct? (if so why? ) or should it say memory must
    be added in increments of 4MB?  (i.e. I would like to add two 4MB simms
    not remove the 8 1MB simms and replace them with four 4MB simms).

Q2. If I have to rip out the 8 1MB simms and replace them with four 4MB
    simms are the 1MB simms the same type used in the SPARCstation 1 & 1+?

			   ** SPARCstation IPC **


HARDWARE AND SOFTWARE CONSIDERATIONS
------------------------------------

Memory Expansion Capability:

SPARCstation IPC has 12 SIMM slots on the CPU board.  8MB is the standard
SPARCstation IPC configuration, filling 8 of the 12 on-board slots.  The
remaining 4 slots can be filled with either 1MB or 4 MB SIMMs resulting in
12 or 24 MB of on-board memory.  As with SPARCstation 1+, memory must be
added in increments of 4 SIMM modules at a time.  If the 8MB of memory
installed in the factory is removed, up to 48MB of memory can be installed
using 4MB SIMMs.
