About Memory This system uses a 240-pin memory module called Double Data Rate-2 (DDR-2), not the old 184-pin memory module called Double Data Rate (DDR). The main board can support maximum 2GB in memory. Note Windows 95, 98SE, and ME support maximum 512MB. Installing a memory with higher capacity than 512MB may cause malfunctioning of the system. Before Expanding the Memory When disassembling the computer, wear gloves to protect internal parts of the computer and slot cards from damage. As the memory is sensitive to static electricity, be careful with the static electrici-

ty when removing or installing a memory. Check the specifications of the current memory and the new memory before expanding the memory. Unlike SIMM, DIMM is of 64 bits. Therefore, single DIMM can function, and you can add DIMM by one. Note When expanding the memory, add a memory with the same specification (DDR-2 SDRAM for 1.8V). (The shape of the memory may differ depending on the product model.) The DDR-2 memory provides greatly improved transmission rate than existing memo-

ries, and is differently shaped. 74 System Expansion This computer supports PC3200/4300, DDR-2 specification. When expanding the memory, use only unbuffered DDR SDRAM DMM When inserting two same memories in same-colored DIMM slots, the computer will oper-

ate in Dual Channel mode. FSB Frequency Usable Memory 400/533 MHz PC3200/4300-DDR-2 SDRAM 400/533MHz Preparing a Memory Before purchasing memory, study the specifications and features of the current memory. Specification : PC3200/4300 (240-pin DDR-2 SDRAM) Rate Type
