Increasing Memory Capacity - IBM ThinkPad 755CX Manual

Increasing Memory Capacity

IC DRAM card
DIMM
Increasing memory capacity is an effective way to make programs
run faster. You can increase the amount of memory in your
computer by installing either an IC DRAM card or Memory Modules
(DIMMs) . Because the computer has only one slot for a memory
card, you cannot use both an IC DRAM card and DIMMs at the
same time.
The computer has one slot that accepts an IC DRAM card with any
of four capacities: 2MB, 4MB, 8MB, and 16MB. Because your
computer comes with 8MB of memory, the maximum memory
capacity is 24MB if a 16MB IC DRAM card is installed.
You might want to install more memory to maximize the capability of
your computer. Instead of using IC DRAM cards, you can install a
dual inline memory module adapter (DIMM adapter), with one or two
DIMMs, in the same slot you would install the IC DRAM card. The
memory capacity can be expanded up to 40MB. The DIMM adapter
has two sockets for future expansion. Three different capacities of
DIMMs (4MB, 8MB and 16MB) and the DIMM adapter are available
as options.
