Quad-Core Mac Pros to Support 16GB Memory Expansion. really!

Other World Computer is selling 4GB SDRAM memory sticks for the Quad-Core Nehalem Mac Pros that were announced in March. A MacRumors reader emailed the company to confirm that they were in fact successfully tested on the Quad-Core machines.

Apple specifies that the Quad-Core Mac Pros only support up to 2GB memory sticks in either of its four memory slots, which suggests that the limit is 8GB. OWC is offering the ability to increase that limit to 16GB.

This kind of discovery could ensure that the Quad-Cores will be maximized at full capacity. Apple has been known to under-advertise the maximum RAM capacities for their machines.
