Good afternoon. I have a Mac Mini, which came with a 2 Gb 1333 MHz PC3-10600 DDR3 SO-DIMMs but I already tried to upgrade with 2 kits:
- Timetec 8GB KIT(2x4GB) Compatible for Apple DDR3 1333MHz PC3-10600
- Timetec 16GB KIT(2x8GB) Compatible for Apple DDR3 1333MHz PC3-10600 CL9
And after I installed both upgrades, the Mac Mini does the chiming sound repetitively. But when I put the 2 Gb stick back it works. Am I missing any step or just being unlucky with the RAM sticks?
