2 System Features

Main Memory

Main Memory
There are two 168-pin DIMM slots on the system board for installing
main memory; DIMM slots 1 and 2. All HP Vectra VEi 8 PC models are
supplied with one memory module (either 32 MB or 64 MB non-ECC
SDRAM) in one of the two slots, leaving the remaining slot free for
memory upgrades. Only HP memory modules are supported.
The slots can be filled in any order. Memory upgrades are available in
single 100 MHz modules of 32 MB, 64 MB, 128 MB or 256 MB modules.
Note that although the 256 MB modules provided by HP as an
accessory are ECC, the ECC feature is not used by this PC.
Replacement of the supplied memory module is necessary to obtain the
512 MB maximum memory.

Processor

The PC is equipped with a single Intel Pentium II (350 or 400 MHz) or
Pentium III processor (450 or 500 MHz). The Single Edge Contact
Cartridge (SECC) packaging includes a dedicated 512K level 2 cache
and heat sink. The processor connects to the system board through a
Slot 1 (SC242) socket.
The Pentium III has the same basic core architecture as the Pentium II
but has an additional 70 multimedia-oriented instructions, bringing
enhanced performance to floating point intensive operations such as
3D and video. To fully exploit this technology, applications have to be
optimized for the Pentium III.
To find out more about Pentium II and Pentium III processors, refer to
the Technical Reference Manual - Vectra Technology.

Setting Bus Frequency Manually

There is a 14.318 MHz crystal oscillator on the system board. This
frequency is multiplied to 100 MHz by a phase locked loop. This is
further scaled by an internal clock multiplier within the processor.
