Upgrading the Qube 3
Components
Your Qube 3 comes equipped with two Dual Inline Memory Module (DIMM)
slots, one of which is used for existing memory, one available PCI slot, and one
or two hard disk drives. You can add components to enhance your Qube 3.
The Qube 3 automatically detects a new DIMM, PCI card or hard disk drive.
Before you purchase a component to add to the Qube 3, ensure that the
component is of the right type and that it will fit in the allocated space.
• The DIMM modules must be PC100 SDRAM. They must be less than
2.5 inches (63.5 mm) tall and less than 0.4 inches (10.1 mm) thick.
• PCI cards must be less than 5.5 inches (139 mm) long.
• Hard disks must be IDE or ATA and should support UDMA/33. They must
be 3.5 inches (88.9 mm) wide, and 1 inch (25.4 mm) tall. This is commonly
known as a 3.5 inch, half-height drive.
Memory
The Qube 3 comes equipped with two Dual Inline Memory Module (DIMM)
slots, one of which is used for existing memory. The Qube 3 supports a
maximum of 512 MB of memory, using two DIMM modules of 256 MB each.
You can have mismatched sizes of memory modules (for example, you can install
a 128 MB module and a 64 MB module together). If you have mismatched
module sizes, install the larger module in slot 1. See Figure 108.
