Title: C79EGMST CreationDate: 02/10/98 09:24:42 Increasing Memory Increasing Memory Increasing memory capacity is an effective way to make programs run faster. You can increase the amount of memory in your computer by installing a dual inline memory module (DIMM), available as an option. Different capacities of DIMM are available. You can install a DIMM directly in the memory slot on the bottom of the computer. Your computer memory capacity can be expanded up to 160 MB (32 MB base memory and two 64 MB DIMM options). Attention The ThinkPad 600 computer supports the static dynamic random access memory (SDRAM) card only. It does not support the enhanced data output dynamic random access memory (EDO DRAM) card. If you install a DIMM that is not supported by your computer, a 225 error code might appear when the system starts. The appropriate memory option can be purchased through your IBM reseller or IBM marketing representative. To install the DIMM, do the following: 1 Power off the computer; then disconnect the AC Adapter and all cables from the computer. 2 Close the LCD, turn the computer over again and then remove the battery pack.
