Figure 4-8. Removing Memory Modules
Microprocessors
Your system contains up to two Intel® Xeon™ 400- or 533-MHz front-side bus microprocessors. The 400-MHz front-side bus processors provide a minimum
internal operating frequency of at least 2.0 GHz, with a front-side bus speed of 100 MHz, an address bus speed of 200 MHz (doubled address transfer rate),
and a data bus speed of 400 MHz (quadrupled data transfer rate).
The system's DDR SDRAM memory modules, which are rated for 266-MHz operation, run at 200 MHz in a system using a 400-MHz front-side bus processor.
To take advantage of future options in speed and functionality, you can add a second microprocessor or replace either the primary or secondary
microprocessor.
Each microprocessor and its associated level 2 (L2) cache memory are contained in an FC-PGA2 package that is installed in a ZIF socket on the system board.
The secondary microprocessor must have the same operating frequency and cache size as the primary microprocessor.
The following items are included in the microprocessor upgrade kit:
l
A microprocessor
l
A heat sink
l
Two retention clips
The following subsections describes how to remove and install a microprocessor in either the primary or secondary microprocessor connector.
Removing a Microprocessor
1.
Remove the optional front bezel, if present. See "
."
2.
Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.
3.
Open the system covers. See "
."
4.
To remove the two retention clips that secure the heat sink to the microprocessor socket at both ends, press down firmly on the release tab of each
retention clip until it disengages from the socket. See
NOTICE:
The second microprocessor must be of the same type and speed as the first microprocessor.
CAUTION:
Ensure that you install only microprocessors purchased from Dell and intended for this system. Using a different microprocessor could
cause data loss, system damage, or personal injury.
NOTE:
When installing a new microprocessor, always use the new heat sink that is shipped with the microprocessor upgrade kit. Thermal interface
grease on the underside of the heat sink is critical to maintaining optimum contact between the heat sink and the microprocessor. Used or older heat
sinks may not have enough grease remaining on them to ensure proper contact.
CAUTION:
Only trained service technicians are authorized to open the system covers and access any of the components inside the system. See
the System Information Guide for complete information about safety precautions, working inside the system, and protecting against electrostatic
discharge.
NOTICE:
Never remove the heat sink from a microprocessor unless you intend to remove the microprocessor. The heat sink is necessary to maintain
proper thermal conditions.
CAUTION:
The microprocessor chip and heat sink can become extremely hot. Be sure that the microprocessor has had sufficient time to cool
before handling.
