Upgrading the System Memory

The Raptor AT allows an upgrade of the system memory with up to 384MB unbuffered SDRAM and up to 768MB registered SDRAM DIMM modules. ECC and non-ECC modules are supported. PC100 memory modules are recommended, but required for PIII or 100MHz FSB operation. The Raptor AT offers 3 DIMM memory sockets. It is very important that the quality of the DIMM is good. Undesirable operation of the system may result if poor quality DIMMs are used. Always purchase your memory from a reliable source.

Upgrading the Microprocessor

The latest revision of the Raptor AT currently supports socket PGA370 architecture Intel Celeron Processors and PIII PGA processors. Please, check the manufacturer’s web site for details and revisions regarding CPU speed.

Since the Raptor AT features CPU auto-sensing device there is only one jumper to be set when changing the CPU, JP11, if it's no set to auto. This jumper is the Clock Speed selector.
