Installing Memory DIMMs

Your new motherboard has four 240-pin slots for DDR3 memory. These

slots support 256 Mb, 512 Mb and 1 Gb DDR3 technologies for x8 and x16

devices. There must be at least one memory bank populated to ensure

normal operation. Use the following the recommendations for installing

memory. (See Figure 1 on page 6 for the location of the memory slots.)

 One DIMM: Install into slot 0. You can install the DIMM into any slot,

however, slot 0 is preferred.

 Two DIMMs: Install into either slots 0 and 1 or 2 and 3. The idea is to

not have the DIMMs in adjacent slots.

 Four DIMMS: Install into slots 0, 1, 2, and 3.
