*Note: The image above is used to illustrate a concept and may not represent the actual
image of your motherboard.
The Trinity 400 uses a 64-bit data path from memory to CPU and can accommo-
date up to 768MB of SDRAM. The 168-pin DIMMs (Dual In-line Memory
Modules) must be of the 3.3V, unbuffered variety. The position of the notch in
the SDRAM key position will tell you whether or not a DIMM is unbuffered
(see the Figure 2-7 below). All installed memory will be automatically detected,
so there is no need to set any jumpers.
