The motherboard is theoretically designed to support 2.0 gigabytes (GB) of memory based on 512 Mbit technology. However, this technology has not been validated on this motherboard. Gateway and Intel have qualified this board for 1 gigabyte (GB) of memory. Double Data Rate (DDR) memory features include: 2.5-volt (V) only, 184-pin DDR SDRAM DIMMs with gold-plated contacts Unbuffered single-sided or double-sided DIMMs Minimum memory: 64 megabytes (MB) 200/266-megahertz (MHz) DDR SDRAM DIMMs Serial Presence Detect (SPD) Suspend to RAM Unbuffered non-ECC DIMMs only

Note: When reseating any components or working inside the case, unplug the power cord and wait for the green light to turn off (10 seconds maximum). There is more available current supplied to this motherboard than others. Failure to unplug the power cord may cause shorts and hot spots on the motherboard and the component you were working with.

DDR SDRAM Defined

DDR memory is the next generation SDRAM. Like SDRAM, DDR is synchronous with the system clock. The big difference between DDR and SDRAM memory is that DDR reads data on both the rising and falling edges of the clock signal. SDRAM only carries information on the rising edge of a signal. Basically, this allows the DDR module to transfer data twice as fast as SDRAM. For example, instead of a data rate of 133 MHz, DDR memory transfers data at 266 MHz.

DDR modules, like their SDRAM predecessors, are called DIMMs. They use motherboard system designs similar to those used by SDRAM. However, DDR is not backward-compatible with SDRAM-designed motherboards. DDR memory supports both error correction code (ECC), typically used in servers, and non-parity, used on desktop/laptop computers.
