Installing And Removing Ram - Power Computing PowerTower Pro User Manual

The DIMM slots are organized into two banks, A and B. Bank A is toward the bottom and
Bank B is above it, as labeled on the motherboard. Each bank has four slots, numbered A1Ð
A4 and B1Ð B4.
DIMMs can be inserted in any order, but to achieve best performance, insert DIMMs of the
same capacity in corresponding slots (A1 with B1, A2 with B2, etc.), to interleave RAM
memory.
All DIMMs must be 168-pin, fast-paged mode, 70-nanosecond RAM access time or faster.
You can install 8 MB, 16 MB, 32 MB, 64 MB, or 128 MB DIMMs up to a total capacity of
1 GB (i.e. 1024 MB).
To increase your systemÕs RAM, install additional DIMM modules in vacant DIMM slots;
if there are no vacant slots, remove one or more lower-capacity DIMMs (see ÒRemoving a
DIMMÓ on page 80) and replace them with modules of higher capacity. (see ÒInserting a
DIMMÓ on page 80.)
