Sadly, this RAM won't work in my Mac Mini, which is the same as the one you have kenreau.
The speed (mHz) of what ratso is selling is too fast for the unibody Minis with the DVD/CD drive, and would cause them to be unstable according to OWC.
If you want to use this RAM in a Mac Mini it would need to be in a unibody Mini without the DVD/CD drive.
