Continuously Batch Tested in Actual Machines
Our extensive Test Lab is not just used for preliminary compatibility testing. In addition to the extensive testing each and every OWC memory module undergoes before shipping (other brands just spot check, if they test at all), we also continuously batch test our modules in the actual machines.

We also use the lab to obtain benchmark information to demonstrate how having more memory will deliver higher real-world use performance from your machine.

Now you can enjoy that experience with full confidence knowing our Test Lab assures OWC brand memory upgrades will deliver the best operating performance available.
