HP Vectra XU 6/xxx PC Series

Main Memory

The PC has four banks on the system board for installing main memory; banks
A, B, C and D. Each bank consists of two sockets. The PC is supplied with 16, 32
or 64 MB of main memory (two memory modules installed in one bank). The PC
uses 60-ns ECC DRAM.
Memory modules must be installed in identical pairs, so that each bank with
memory installed contains two memory modules of the same size and type.
The PC is supplied with one bank of memory modules. This can be a pair of
modules of type "interleave 8" or a pair of type "interleave 16". These can be
replaced or extended with memory modules of the same type.
Main memory on an "interleave 8" type of PC can be extended to a maximum of
128 MB by replacing the 16 MB base memory with four D3555B kits (32 MB each
kit). Main memory can be extended to a maximum of 112 MB without replacing
the base memory.
Main memory on an "interleave 16" type of PC can be extended to a maximum
of 512 MB by replacing the 32 MB base memory with four D3540A kits (128 MB,
"interleave 64" each kit). Main memory can be extended to a maximum of
416 MB without replacing the base memory.
To order the appropriate main memory upgrade kit, check the PC memory
configuration using the "HP Vectra XU 6/xxx & VT 6/xxx Memory Configuration
Utility". This utility will indicate the supported accessories.
