Dell Inspiron 630m, 640m Memory Installation Guide


Dell Inspiron 630m, 640m Memory Installation Guide.

Your Dell computer comes equipped with two memory slots/connectors labeled DIMM A and DIMM B. DIMM A (located under the keyboard) holds the primary memory module as configured from the factory. DIMM B (located on the bottom of the computer) holds any additional memory you may have ordered. If you did not order additional memory, DIMM B will be empty.

Generally, if you are adding memory, you will install a memory module in DIMM B only. If you are upgrading the memory, you may need to install memory modules in DIMM A and DIMM B, depending on the extent of the upgrade.

CAUTION: Before you perform any of the procedures in this section, follow the safety instructions in the Product Information Guide.

NOTICE: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface (such as the back panel) on the computer.

1. Follow the instructions in General Safety Guidelines for Working with Notebook Computers.

2. Loosen the two captive screws securing the memory module cover, then remove the cover and set it aside. Remove memory module if installed.

NOTICE: To prevent damage to the memory module connector, do not use tools of any kind to spread the metal clips that secure the module.

  • a. Align the notch in the memory module edge connector with the tab in the connector slot.
