Mac Pro RAM upgrade
Tuesday, July 15th, 2008So, the other day I installed some extra RAM into my Mac Pro computer (two sticks of 2GB RAM). Originally, I put one in each riser. After rebooting a couple times only to see that the new RAM still didn’t register, I googled some instructions and discovered something.
Anyone who owns a Mac Pro should know that RAM must be installed in pairs, but what you may not know is that the new RAM must also be installed on the same riser.
There are two platforms of RAM in the Mac Pro called risers. They are generally referred to as the upper and lower risers.
If you install one stick of new RAM on the upper riser, and one on the lower, the computer will not recognize it. They must be next to each other on the same riser.
