8.7.1Installing DIMMs

A single memory module will support DIMM population in various configurations (including empty sockets). However, if fewer than 16 DIMMs are installed on a module, the preferred population order is in groups of four sockets (Jx) (see also figure 32 on page 109):

1

J1-J5-J9-J13

 

 

2

J2-J6-J10-J14

 

 

3

J3-J7-J11-J15

 

 

4

J4-J8-J12-J16

 

 

This recommendation ensures optimum performance, signal integrity and cooling.

IThe maximum capacity is limited to 16 GB if only one module is installed. The capacity increases to 32 GB if two modules are used.

BIOS automatically detects, sizes and initializes memory (conventional and extended memory) according to the type, size and speed of the installed DIMMs and reports memory size and allocation to the system via the configuration registers.

VCAUTION!

Observe the safety information and the information on handling electro- static-sensitive components in the chapter “Important notes” on page 11.

Use extreme care when installing a DIMM. Too much pressure can damage the ejector levers.

The DIMMS are equipped with coded connectors so that they cannot be installed incorrectly.

ÊRemove the DIMM from its antistatic package.
