Buyer's Guide
Memory Expansion Boards
Memory expansion boards add random access memory (RAM) to your computer system, often increasing the speed, storage, and power of your machine. Some of the boards listed below add other features, such as a ramdisk, serial and parallel ports, and utility software. Looking through the charts, you'll find the name of each board, its features, and its price. Prices are rounded to the nearest dollar and are usually for boards without memory chips, but some boards are sold with chips included. Either way, we suggest that you verify the price before you order because of the daily fluctuations in price and supply.
