Replacing memory

The version 2.5 BCM1000 comes equipped with 256 MB of Random Access Memory (RAM). The previous version 2.0 release of the hardware contains 128 MB of RAM. In both cases, the memory resides on a Dual In-line Memory Module (DIMM) in center of the main printed-circuit board (motherboard). This board contains space to add a second DIMM, or you can upgrade the existing DIMM.

Figure 130 provides an overview of the process for replacing or adding memory chips.
