Product Features
DRAM Main Memory
Modules
The HP Vectra XU 6/xxx PC and HP Vectra VT 6/xxx PC are supplied with
16 MB of main memory. Upgrade DIMMs can be installed, a pair at a time, to
increase this to a maximum of 256 MB.
There are eight memory sockets, grouped into four banks (labeled A to D on
the system board). Each bank comprises two sockets. The banks can be
filled in any order, but always with pairs of DIMMs of the same capacity and
same type (ECC or non-ECC).
❒
16 MB ECC (a pair of 8 MB ECC modules)
❒
16 MB non-ECC (a pair of 8 MB non-ECC modules)
❒
32 MB ECC (a pair of 16 MB ECC modules)
❒
64 MB ECC (a pair of 32 MB ECC modules).
Error Correcting Code
(ECC)
Although each memory module stores 64 bits of data (8 bytes) at a time, each
ECC memory module is accessed by a 72-bit bus. The extra bits are used for
the error correcting code (ECC). This allows single-bit data errors not only
to be detected, but also to be corrected.
PCI Bus Devices
• video controller
• Fast-20 SCSI-2 interface

• other accessory boards.
Video Controller Board
The HP Vectra XU 6/xxx PC and HP Vectra VT 6/xxx PC are supplied with
a Matrox MGA Millennium video controller on a board that fits in a PCI
accessory slot. The board is fitted with 2 MB of DRAM video memory, as
standard. This is upgradeable to 4 MB by installing a 2 MB video memory
module. Upgrading to 8 MB is also possible, using a 6 MB module (available
from Matrox).
Drivers are not integrated into any of the operating systems. HP provided
drivers must be installed.
