Upgrading the System Memory
The Raptor MicroATX allows an upgrade of the system memory with
up to 512MB unbuffered SDRAM DIMM modules in two memory
slots. ECC and non-ECC modules are supported (Although ECC
modules may be used, the 815E chipset does not have support for
ECC). It is very important that the quality of the DIMMs is good.
Unreliable operation of the system may result if poor quality DIMMs
are used. Always purchase your memory from a reliable source. We
strongly recommend using PC133 memory module for higher
performance when using 133MHz PSB processors, but PC100 memory
modules may be used. PC66 memory modules cannot be used even if a
Celeron 66MHz PSB processor is being used.
Upgrading the Microprocessor
The latest revision of the Raptor MicroATX currently supports full
series of Intel Celeron (FC-PGA 66MHz PSB, FC-PGA 100MHz PSB
and FC-PGA2 (0.13u) 100MHz PSB) and Pentium III (FC-PGA
100MHz PSB, FC-PGA 133 PSB and FC-PGA2 (0.13u) 133MHz PSB)
PGA370 processors. Please, check the manufacturer's web site for
details and revisions regarding CPU speed.
Since the Raptor MicroATX features CPU auto-sensing device there is
no jumper to be set when changing the CPU.
