RAM Installation
The Tiger 100 uses a 64-bit data path from memory to CPU and can accommo-
date up to 1024MB of SDRAM. The 168-pin DIMMs must be of the 3.3V,
unbuffered variety. The position of the notch in the DRAM key position will
tell you whether or not a DIMM is unbuffered (see the figure below). All
installed memory will be automatically detected, so there is no need to set any
jumpers.
Some details of memory installation:
•
One unbuffered DIMM must be installed for the system to POST.
• The mainboard supports 8MB, 16MB, 32MB, 64MB, 128MB SDRAM; and
256MB registered SDRAM DIMM modules.
