DRAM Main Memory Modules

• The HP Vectra VL 5/xx series 3 PC has six sockets on the system board. 8 MB or 16

MB of memory is supplied as standard, expandable to 192 MB.

• The HP Vectra VE 5/xx has four sockets on the system board. 4 MB or 8 MB of memory

is supplied as standard, expandable to 128 MB.

Each pair of sockets forms a bank. When two memory modules are installed within the same

bank, they must be of the same size.

The PCs use 70 ns, 32-bit wide, memory modules. When additional memory modules are

installed, the following rules must be applied to get the best performance:

1. Install two identical-size SIMMs in the same bank to enable 64-bit wide access to this

bank.

2. Install four identical-size SIMMS in bank A and B to enable memory interleaving

between the two banks.

The memory upgrades available are:

• 4 MB, 32-bit, 70 ns (D2690A) or 4 MB, 36-bit, 70 ns (D2974A)

• 8 MB, 32-bit, 70 ns (D2691A) or 8 MB, 36-bit, 70 ns (D2975A)

• 16 MB, 36-bit, 70 ns (D2297A)

• 32 MB, 36-bit, 70 ns (D2298A)

When 36-bit SIMMs are installed, it is possible to enable parity checking by enabling the

parity switch (PARIT) on the system board.
