5-6 Installing Memory

Memory Support

The X7DCT/X7DCT-10G has six 240-pin DIMM slots that can support up to 48 GB

of registered ECC DDR2-667/533 SDRAM (for a total of 96 GB in the system).

The memory scheme is interleaved, so you must populate two slots at a time,

beginning with slot 1A and 1B, then slots 2A and 2B, and ﬁ nally into slots 3A and

3B if six DIMMs are to be installed. See table below.

Installing Memory Modules

Insert each memory module vertically, beginning with slots 1A and 1B (see

above). Pay attention to the notches along the bottom of the module to pre-

vent inserting it incorrectly.

Gently press down on the DIMM module until it snaps into place in the slot

(see Figure 5-3).

Repeat to install a total of four or six DIMMs if needed.

Note: Due to allocating memory to system devices, memory remaining available

for operational use will be reduced when 4 GB of SDRAM is used. The reduction

in memory availability is disproportional. (Refer to the Memory Availability Table

on the following page for details.)

CAUTION! Exercise extreme care when installing or removing

DIMM modules to prevent any possible damage.

Notes: i. DIMM slot# specified = DIMM slot to be populated; “---“ = DIMM slot not to be

populated. ii. Both 533 MHz and 667MHz memory is supported; however, you need to use

modules of the same speed and type. iii. For memory to work properly, you need to follow

the restrictions listed above.
