IBM 6866 Personal Computer User Manual


 
System board memory
The following matrix cross-references the name of the
computer (printed on the logo) and the size, speed, and
type of memory modules supported in the computer.
Note
RAMBUS inline memory module (RIMM) is used in the
type 6584/6594 computer. RIMM modules are not
compatible with SIMM or DIMM memory modules.
Refer to the information below regarding RIMM
memory for type 6584, 6594.
Note
For maximum 512 MB configuration, two 256 MB
PC800 memory RIMMs must be installed. PC700
memory RIMMs can not be used.
Supported RIMM memory configuration
Type 6584/6594 has two RIMM memory sockets. RIMM
sockets must either have a RIMM memory module or a
C-RIMM (RIMM Continuity module) installed. There can
be no empty RIMM sockets. At least one socket must
have a RIMM memory module installed.
If new memory is to be added, remove a C-RIMM and
install the new RIMM.
If memory is to be removed, remove the RIMM and
install a C-RIMM.
RIMM sizes of 128 MB and 256 MB are acceptable.
RIMM sockets can be filled in any order. ECC or
non-ECC, RAMBUS dynamic random access memory
(RDRAM) are supported.
Note
Mixed RIMM speeds will run at the lower speed.

RIMM diagnostic approach
Identify any Beep or POST codes. See “Symptom-to-FRU
index” on page 82.
Use the IBM PC Enhanced Diagnostics program to run
memory tests. See “IBM PC Enhanced Diagnostics error
codes” on page 1.
