Memory Installation
The LittleBoard 550 uses a single DIMM in the DIMM slot available on the topside of the board. The
LittleBoard 550 supports PC 133 (133MHz or faster), 3.3V, 8ns, 168-pin, SDRAM DIMMs.
NOTE Ampro recommends using only PC 133 (133MHz), 3.3V, 7.5ns, 168-pin,
SDRAM DIMM, but PC 100 (100MHz, 10ns) will function. PC 133
provides the best performance for the Eden processors.
Tools Required
Use an anti-static service kit (or the equivalent) to remove or install the DIMM. An anti-static service
kit should include a static-dissipating work surface, a chassis clip lead, and a wrist or ankle strap.
Memory Installation Guidelines
• When handling a DIMM, observe anti-static discharge precautions to avoid damage.
• The LittleBoard 550 uses PC 100 or PC 133 (100MHZ, 133MHz, or faster) SDRAM DIMMs,
which are electrically different from EDO DIMMs.
• The following DIMMs sizes are available from Ampro: 32MB, 64MB, 128MB, 256MB, 512MB,
or 1GB.
• The LittleBoard 550 supports up to 1GB of memory in the DIMM slot.
