The Thunder X uses a 64-bit data path from memory to CPU and can accom-
modate up to 1024MB of SDRAM (2GB of SDRAM has not been validated).
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 2-5 on the
following page). All installed memory will be automatically detected, so there
is no need to set any jumpers.
