OWC DDR2 800 MHz SO-DIMM Reviews

New life for my old Mac

By Drury

My 2008 iMac had been running pretty slow with newer operating systems. It had only 2GB of RAM and I was close to getting a new computer, but decided to increase the memory before making that decision. My old iMac runs much faster now after a $20 4GB Memory from B&H and about 10 minutes to install. I expect to get another couple of years of use out of it now.
