●
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
●
If the system is populated with two DIMMs it runs at the maximum speed of the DIMMs. However, if a
single DIMM is added to this configuration, DIMM speed may be reduced to the minimum system
memory speed configuration, even if the additional DIMM is specified to run at the higher speed.
Removing and installing DIMMs
IMPORTANT:
You must disconnect the power cord and wait approximately 30 s for the power to drain before
adding or removing memory modules. Regardless of the power state, voltage is always supplied to the
memory modules as long as the computer is plugged into an active AC outlet. Adding or removing memory
modules while voltage is present may cause irreparable damage to the memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, use memory
modules with gold-plated metal contacts to prevent corrosion, oxidation, or both, resulting from having
incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before beginning
these procedures, make sure that you are discharged of static electricity by briefly touching a grounded metal
object.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the
module.
Before removing memory modules, follow these steps:
1.
Prepare the computer for disassembly (
Preparation for disassembly on page 20
).
2.
Remove the access panel (
3.
Remove the front bezel (
).
4.
Remove the drive cage (
).
Remove memory modules:
1.
To remove a memory module, open both latches of the memory module socket (1), and then remove the
memory module from the socket (2).
