Table A-1. Supported Memory SIMM Sizes and Configuration
Note 1: 512K x 32 SIMMs are supported, however, they must be double sided SIMMs
Note: 2 When using Single Sided High Density SIMMs such as 32 MB single sided, 64 MB double sided, or 128
MB SIMMs, SIMMs that have less than 32 MB per side will NOT be recognized in the system.
The Advanced/RH will support both Fast Page DRAM or EDO DRAM SIMMs, but they cannot be mixed within
the same memory bank. If Fast Page DRAM and EDO DRAM SIMMs are installed in separate banks, each bank
will be optimized for maximum performance. Parity or ECC generation and detection are supported when parity
SIMMs are the only SIMMs present on the motherboard. SIMM requirements are 70 ns Fast Page Mode or 60 ns
EDO DRAM with tin-lead connectors.
8 MB is the minimum memory size supported by the Advanced/RH motherboard. 512 MB is the maximum
memory that can be supported in any combination of SIMMs from the table.
REAL TIME CLOCK BATTERY REPLACEMENT
The battery can be replaced with a Sanyo CR2032, or equivalent, coin cell lithium battery. This battery has a 220
mAh rating.
CPU UPGRADE
A Type 7 Zero Insertion Force (ZIF) socket provides users with a performance upgrade path to the P54CTB
OverDrive technology. LPX form factor makes it easier for the end user to replace the processor.
GRAPHICS MEMORY UPGRADE
The ATI-264VT graphics subsystem has either 1 or 2MB of SGRAM soldered down on the base board.
Video memory can be upgraded with a daughter card that is compatible with ATI PCI add in cards.
Information on the memory upgrade can be obtained by contacting ATI Technologies at the numbers listed
below in the HARDWARE MPEG MODULE section.
