Upgrading main memory
The system board incorporates four locations for installing memory modules in DIMM
format (bank 0 to bank 3). The board supports a maximum of 512 Mbytes. On 333-MHz
processors with extended cache ability only, the maximum memory capacity is 1 Gbyte.
You may use EDO DRAM memory modules of 64, 128 or 256 Mbytes.
Equipping must be performed starting with bank 0 in sequence.
EDO-DRAM = Enhanced Data Output Dynamic Random Access Memory
!
You may only use buffered 3.3V memory modules. Unbuffered memory
modules are not permitted.
EDO-DRAM memory modules must have an access time of 60 ns or less.
Installing memory modules
Ê
Flip the holders on each side of the relevant location outwards.
Ê
Insert the memory module into the location.
Ê
At the same time flip the lateral holders upwards until the memory module snaps in
place.
Removing a memory module
Ê
Flip the holders to the right and left of the location outwards.
Ê
Pull the memory module out of its location.
Replacing the Pentium II
System board D992 dual
The system board can be upgraded with a second Pentium II processor in slot 2. You can
replace the Pentium II processor in slot 1.
If the system board contains only one processor in slot 1, a terminating board must be
inserted in slot 2 and there is no voltage converter for processor 2 inserted.
!
The second Pentium II processor must have the same clock rate as the first. A
suitable multiprocessor operating system must be used if dual operation is
required. On the processor modules you may use only processors of the same
type.
System board D992 mono
The system board can only be operated with a Pentium II processor in slot 2. There is a
terminating board in slot 1. Voltage converter slot 1 is empty.
