Probably. If the 5-5-5-15... timing is the same as your existing RAM and if the 1.8V is the same as your existing RAM. But you will be much better off if you find a matching pair to the RAM you now have. Look on the sticks for the model number and search for 2 of the same kind. It'll give you 4GB instead of 3GB, but if you only have 32 bit Windows it can use most of that anyway.
