Processor Speed Settings

Processor speed for the IntelliStation type 6868/6878
computer is fixed and is determined by the processor.
There are no settings required.

System board memory (2 GB - maximum)

Note: RAMBUS inline memory module (RIMM) is used in the type 6868/6878 computer.
RIMM modules are not compatible with SIMM or DIMM memory modules.

RIMM sizes of 64 MB, 128 MB, 256 MB, and 512 MB are acceptable.
RIMM sockets, within each memory channel, can be filled in any order.
However, both memory channels must be populated the same.
ECC or non-ECC, RAMBUS dynamic random access memory (RDRAM) are supported.
If ECC and non-ECC are installed together, all memory will function as non-ECC.

Note: Mixed RIMM speeds will run at the lower speed.

Supported RIMM memory configuration

Type 6868/6878 has two memory channels with two memory sockets for each channel making a total of four RIMM memory sockets.
RIMM sockets must have a RIMM memory module or a C-RIMM (RIMM Continuity module) installed.
There can be no empty RIMM sockets.
RIMM sockets must contain either a RIMM or a C-RIMM.
At least one socket, from each memory channel, must have a RIMM memory module installed.

Note: Both memory channels must be populated the same.

Each RIMM socket supports a maximum of 512 MB of memory.
