General Information
Memory Specifications and Upgrades
Mac mini computers have a single memory slot. This slot accepts a standard PC2700 or
PC3200 184-pin DIMM with the following specifications:
• PC2700 or PC3200 Synchronous DRAM (SDRAM)
• 2.5 volt
• 8-byte
• non-parity
• 64-bit wide
• 184-pin module
• maximum of 16 memory devices on the DIMM
• unbuffered—do not use registered or buffered SDRAM
• maximum height of 50 mm
Using PC3200 memory does not provide additional speed benefits. Although the Mac mini
supports PC3200 DIMMs, the PC3200 RAM will operate at PC2700 (333 MHz) speeds.
The Mac mini has a 256 MB base memory configuration, which can be expanded up to a
maximum of 1 GB. The Mac mini can be configured to order (CTO) with 512 MB or 1 GB of
SDRAM. Additional memory should be installed by an Apple Authorized Service Provider.
Video memory
The Mac mini has 32 MB DDR of soldered SDRAM dedicated for video. Video memory
cannot be upgraded.
LED status
The Mac mini has a power light located on the front of the computer in the bottom right
corner below the optical drive slot. The LED displays a steady light, no light, or pulses,
depending on the computer's status. Here's what the Mac mini's LED is telling you.
