Upgrading Memory
Model R1200
To replace or upgrade the memory on the R1200, do the following:
1. Pull the tabs on either side of the memory socket apart to remove the module.
2. Carefully insert the new memory module into the socket, making sure that the
tabs snap inward securing the module in place.
NOTE: Both DIMM slots on the R1200 must be populated with memory modules of
equal size and speed.
Model R2100
The memory upgrade steps for the R2100 PC Blade are the same as above, but
because the memory architecture being interleaved, the memory modules must be
installed in matched pairs on each DDR bus.
DIMM slots U4 and U7 form the outer pair, U5 and U6 form the inner pair. The outer
pair must always be populated. The modules used in the inner pair do not have to
match the modules used in the outer pair, just within each pair.
