The Tomahawk BX/A+ uses a 64-bit data path from memory to CPU and can
accommodate 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 automati-
cally detected, so there is no need to set any jumpers.
