This guide is for experienced technicians who have already
completed the HP Vectra computer family training course.
In particular, it assumes that the reader is already familiar
with the HP Vectra XA 6/xxx and HP Vectra XM 5/xxx
Series 4 PCs, which have a similar structure.

Installing Main Memory Modules
Installing Main Memory Modules
• Each memory bank that you use must contain a pair of identical memory
modules, installed in the pair of sockets for that bank.
• The three memory banks (A, B, C) may be filled in any order, but it is ad-
visable, for performance reasons, to fill them in the order A then B then C.
• Memory can be upgraded in increments of 8 MB, 16 MB, 32 MB or 64 MB
(by installing pairs of 4 MB, 8 MB, 16 MB or 32 MB modules).
• HP does not support PCs in which the user has installed non-HP
memory modules.
Initial Configuration Example Upgrade Paths
Models are supplied with 16 MB or 32 MB
of main memory using a pair of 8 MB or
16 MB, 60 ns, EDO memory modules.
The main memory capacity can be extended
to 144 MB or 160 MB by installing a further
two pairs of 32 MB memory modules.
This can be further extended to 192 MB by
removing the original pair of modules, and
replacing them with a pair of 32 MB
modules.

B2 empty 32 MB
B1 empty 32 MB
A2 8 MB or 16 MB 8 MB or 16 MB
A1 8 MB or 16 MB 8 MB or 16 MB
Banks may be filled in any order, but it is
recommended to fill them in the order of A
then B then C.
Any banks which are occupied must always
be filled with a pair of modules of
identical capacity, type and speed.
Different banks can be occupied by different
capacities of modules, such as a pair of
32 MB modules, a pair of 16 MB modules,
and a bank of 32 MB modules.

C1 empty 32 MB
B2 empty 4 MB
B1 empty 4 MB

MMX Processor
MMX Processor
The new P55C processors, from Intel, are Pentium processors, with the MMX
multimedia extension instructions added to the instruction set.
P55C processors require a different voltage supply. Only use the voltage
regulator model (VRM) that was supplied with the processor.
How to Identify the VRM
The 0950-3188 VRM has the characters “2.8V” marked on it. The 5063-7939
VRM has only the word “Pentium” or a voltage of the form “3.xxV” marked
on it.
How to Identify the Processor
HP Vectra XA PCs exist in two different
forms: one with a system board for a Pentium
or MMX processor, the other with a system
board for a Pentium Pro processor.
All models bear the same front panel logo. Other sources of information
must be sought, in order to ascertain what type of processor is installed.
• The serial label. This is found on the lower front recess of desktop models,
and on the lower part of the right side panel of minitower models. It gives
the following information:
❒Processor type (5/ = Pentium P54 or MMX P55; 6/ = Pentium Pro)
❒Processor frequency (/166 = 166 MHz; /200 = 200 MHz)
❒Product number (D3993A in the example).
The product number is particular useful, since it can be looked up in the
HP Vectra PC Service Handbook.

Precautions When Replacing the Power Supply
• The Intel Inside label. Only models containing an MMX (P55C) processor
have the MMX logo (shown at the top left of the previous page).
• The BIOS version number. This is displayed at the top of the summary
screen (obtained by typing whilst the initial Vectra logo is being dis-
played during the Power-On Self Test phase).
• The ultimate solution is to release the lever on the zero insertion force
(ZIF) socket, and to remove the heat-sink and processor together, as a
single unit. Look at the underside of the processor. Only P55Cs are
marked with the words “MMXTM tech”.
Precautions When Replacing the Power Supply
USB Connector
The HP Vectra XA 5/xxx and VL 5/xxx Series 5 PCs are the first Vectra PCs
to have a pair of USB connectors fitted as standard. When devices become
available on the market, they can be activated from the Setup program.
Model Processor BIOS Version Number
HP Vectra XA 5/xxx PC Pentium P54CS or MMX P55C HA.07.xx
HP Vectra XA 6/xxx PC Pentium Pro GZ.07.xx
With the minitower package, always check the position of the voltage
selection switch.
