8–2 Installing/Removing Memory Modules
Publication 6181-UM001D-EN-P
When adding memory to the RAC6181 Pentium processor board, follow
these guidelines:
•
Use only a standard, unbuffered 168–pin DIMM that conforms to
both PC-100 and Serial Presence Detect (SPD) compliance industry
standards.
•
Use only Synchronous Dynamic Random Access Memory (SDRAM)
type DIMMs.
•
BIOS automatically detects memory size and type (i.e., SDRAM vs.
EDO). It does not detect parity, however, so this must be manually
configured by the end-user in BIOS Setup. The RAC6181 Computer
ships with ECC-type memory, and the Memory Parity Check feature
in BIOS Setup is programmed to “ECC” by default.
•
If a non-ECC DIMM is installed, the Memory Parity Check in BIOS
Setup must be changed/saved to “Disabled”. The system will fail to
boot if ECC is enabled in Setup with a non-ECC DIMM installed.
•
Use only gold-plated lead DIMMs.
When adding memory to the RAC6181 Pentium III processor board,
follow these guidelines:
•
Use only a standard, unbuffered, non-ECC 144-pin SODIMM that
conforms to both PC-100/PC-133 and Serial Presence Detect (SPD)
compliance industry standards.
•
Use only Synchronous Dynamic Random Access Memory (SDRAM)
type SODIMMs.
•
BIOS automatically detects memory size and type (i.e. PC100 or
PC133). Either non-ECC or ECC SODIMMs may be used, but ECC
parity checking is not supported on this system board. The ECC
memory will run in non-ECC mode.
•
Use only gold-plated lead SODIMMs.
