System Memory Configuration - Intel I965P User Manual

2-3 System Memory Configuration

The mainboard accommodates four 240-pin DDR2 DIMM sockets.
• Supports up to 8GB of 533/667/800MHz DDR2 SDRAM.
• Supports unbuffered DIMM configurations defined in JEDEC DDR2 DIMM specification.
Dual Channel interface:
• Dual channel memory access offers increased system performance.
• For dual channel to operate, both channel must be populated with same amount of memory, preferably
of the same type.
• The four DIMM sockets are divided into two colors to help you identify the channel pairs <Figure 1>. Each
dual channel pair has the same color, e.g. DIMM1 and DIMM3. To obtain best performance, simply
mount DIMM sockets of the same color.

* SS: Single-Sided DIMM, DS: Double-Sided DIMM
Memory Installation :
To install, align the notch on the DIMM module with the connector.
Press straight down as shown in the figure until the white clips close and the module fits tightly into the
DIMM socket.
