6-5. Increasing the memory
If you run out of memory while using the computer, you may want to increase the
amount of memory in your computer.
Your computer uses DDR(Double Data Rate) SDRAM DIMM(Dual In-Line Memory
Module) with 184 pins. Your computer supports Unbuffered DDR SDRAM DIMM of
128MB up to 1024MB in size in each socket, and 2048MB total.
ãAlways wear gloves to avoid injury when disassembling the computer
ãStatic electricity can damage memory modules be sure to minimize the static
electricity when replacing memory.
ãMake sure to replace the memory of the same type as the installed memory.
ãDIMM is different from SIMM in that it is configured for 64 bit operation; there
fore, your computer can operate with only one DIMM installed.
About Memory
Before increasing the memory
ãUse a 2.5V DDR SDRAM DIMM.(The shape of the memory may be different depending
on the model) DDR SDRAM enhances the rate of data transmission of the SDRAM and
looks different from SDRAM.
Note
DDR
ãWindows 95, 98SE, ME supports memory up to 512MB total. Increasing the memory
beyond 512MB in these systems may cause errors while using the computer.
Note
75System Expansion
Check the type of memory installed in your computer and refer to the memory config-
uration chart before purchasing a memory.
