Appendix E
Installing Additional DRAM Memory
This appendix explains how to install additional DRAM memory into the
HP VXI Pentium Controller.
Caution
It is strongly recommended that a trained computer service
technician installs any memory upgrade, as SO DIMMs are
more flexible than common SIMMs and are also more costly if
damaged. There is also potential for damage to the controller
itself. An HP Service Technician can perform this task for you.
Contact your HP Service and Support Center for assistance.
The HP VXI Pentium Controller has four SO DIMM sockets supporting
from 16 MB to 256 MB of dual-ported, DRAM memory. The standard
controller comes with two SO DIMM modules installed in two sockets. This
leaves two open sockets available for additional memory.
Please note that because the memory is interleaved, the sockets must be
populated in pairs of identical SO DIMM modules. However, memory
module densities of upgrades may be mixed. For example, if two 8 MB SO
DIMM modules occupy the first two sockets, the remaining two sockets may
be occupied by two SO DIMM modules of any other supported density. If
mixed memory module densities are used, there is no dependency on the
order in which the module pairs are loaded into the sockets pairs.
While the HP VXI Pentium Controller can support both 60ns and 70ns
memory speeds, it is not recommend to mix memory of different speeds in
the same unit. If you chose to ignore this recommendation and install slower
speed 70ns memory in a unit which already has 60ns memory pre-installed,
you must set the
DRAM Speed
setting in the BIOS Advanced Chipset Control
Sub-Menu to
70ns
(See Chapter 3, “Using the BIOS Setup Utility”). This
will cause all the memory in the unit to operate at the same, slower 70ns
speed.
