Table 4-1 System speed factors (actual memory speed dependent on processor)
Module configuration Description of configuration Maximum memory speed*
Single DIMM per channel Configurations with only 1 or 2 DIMM
modules installed only in black slots
4400 MHz
Two single-ranked DIMMs in a channel Configurations with 3 or 4 single ranked
DIMMs (8 GB and 16 GB) installed
4000 MHz
Two dual-ranked DIMMs in a channel Configurations with 3 or 4 dual-ranked
DIMMs (32 GB) installed
3600 MHz
Recommendations for upgrading memory
To make sure that the system can run at maximum speed:
● Use the same capacity memory that is already installed in the computer.
● Buy modules in pairs.
Memory features
● Single-bit errors are automatically corrected.
● Detected multibit errors cause the system to immediately reboot and halt with an F1 prompt error
message.
Loading rules
● Load the memory modules in order of size, starting with the largest module and finishing with the
smallest module.
● Each channel includes two DIMM sockets; black and white connector pairs represent a channel.
Load the DIMMs first in the black sockets and then in the white sockets. Load the DIMMs starting
with the DIMM furthest from the CPU, with the first DIMM loaded in the right-most socket and
alternating sides of the CPU.
IMPORTANT: You must disconnect the power cord and wait approximately 30 seconds for the power
to drain before adding or removing memory modules. Regardless of the power state, voltage is always
