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.
