Pulled from Dell D600 laptop but should be compatible with laptops that use the DDR PC2100 266mhz chip -- Tested to work on Dell 1100 1150 5150 5160 D400 D600
2 x 128MB = 256MB
This is a versatile memory chip that work with many laptops. very useful for testing some dell laptops to be sure it's not memory problem that the board has.
