Your computer only supports modules made with a specific type of chip. Should you find what seems to be the exact same memory elsewhere for a lower price, be sure to double check that the model number matches exactly and the vendor is selling a quality part. When you purchase memory from 4AllDeals, it comes with a lifetime warranty, fast, telephone technical support by USA-based technicians and a quality product that our company stands behind.
