The TravelMate 2200 series is a group of laptops manufactured by Acer. The series includes computers with varying technical specifications, but they all have the same memory capacity. When you're upgrading your memory, knowing the exact amount, type and physical size you need helps ensure the upgrade goes smoothly and avoids potential memory-related problems.

Amount and Capacity
The Acer TravelMate 2200 series can use up to 2 gigabytes, or GB, of RAM. The laptop's memory bay has two memory slots. Each of the slots can hold a maximum memory capacity of 1 GB. To reach the system's 2 GB maximum, install two 1 GB modules, one in each bay. Doing so will require you to remove the memory that Acer installed into the laptop in the factory.
Your Acer TravelMate 2200 laptop uses Double Data Rate, or DDR, memory. It's important that you don't confuse this memory type with DDR2 or DDR3 memory, the successors of DDR technology. Though the names are similar, the three types are not compatible, so DDR2 or DDR3 memory won't work in your computer. The DDR memory you buy should also have "PC-2700" in the name. This specification states that the memory's peak transfer rate is 2,700 megabytes, or MB, per second. The memory may also be listed by "DDR-333," what's known as the memory's "friendly name." The number denotes the memory's speed in megahertz, or MHz, per second instead of MB per second.
As a laptop computer, the Acer TravelMate 2200 uses small outline dual inline memory modules, or SODIMMs. Desktops have much more room within the computer for larger internal components, so they use DIMMs, which are 3.5 inches to 4 inches long. SODIMMs, on the other hand, are only 2.5 inches to 3 inches long. If you tried to put a DIMM into your laptop, it wouldn't even physically fit into the slot. Memory modules have a certain number of pins at the bottom where they connect to the memory module. The memory you buy has to have 200 pins.
Ensure you know these memory specifications before purchasing your upgrade. When the name is written together, the TravelMate 2200 uses up to 2 GB of DDR PC-2700 200-pin SODIMM memory. Follow the manual that came with your computer when you perform the upgrade. While general guides are available online, they may not cover all of the specific steps your computer requires for installing new memory.
