I have a Mac Pro 1,1, purchased in 2006 with 2g RAM. In 2009 I added 8g which the computer recognized. I've noticed some performance issues recently, and checked the RAM, which now only shows 2g.

Any recommendations to deal with this?

It sounds like either your RAM isn't properly seated or your RAM modules may be defective.

I opened the "box" and unseated, then reseated the DIMMS. In profile, Riser B correctly shows the original four 512mb boards. Riser A, however shows four empty slots, where it should show the two 4gb DIMMS I installed three yrs ago. I guess I need to decide if it's worth doing anything further with the problem.

Thanks for the response.

I just called OWC, and the tech had me switch the 4g DIMMS to the B riser. Profile did not recognize them, so they're replacing them under the lifetime warranty.

Thanks again.
