Changing Your Computer Hardware Configuration

Memory Cards

3.Position the memory slots so they face you as shown in Figure 5-45.Note that Figure 5-45also provides the loading sequence for the DIMM cards. This loading sequence must be maintained when you install the DIMM cards, but the size of the DIMM card put in each slot can vary. For example, you can install a 128Mbyte card before a 256Mbyte card and then follow the installation of the 256Mbyte card with another 128Mbyte card. The B1000 and C3000 computers use only 128 Mbyte and 256 Mbyte DIMM cards.

4.Remove the hard disk drive fan as explained in the section “Removing the Fan from the Hard Disk Drive Area” in this chapter, and load the DIMM cards in the slots using the loading sequence provided in Figure 5-45.

NOTE

When installing memory, you need to orient the notches on the bottom

 

edge of the DIMM card so that they are aligned with the keys on the

 

DIMM connector. See Figure 5-46.The keyed DIMM connectors prevent

 

you from installing the DIMM cards backwards.
