3. Remove the memory fan (3) from the computer.
To install the memory fan, reverse the removal procedure.
Memory modules (DIMMs)
To remove the memory modules, use this information and procedures.
The memory sockets on the system board are populated with at least one preinstalled memory module.
To achieve the maximum memory support, you can populate the system board with up to 512 GB of
PC5-4800R, 4800 MHz DDR5, registered, ECC DIMMs configured in a high-performing dual-channel
mode.
NOTE: The system might not operate properly if you install unsupported memory modules.
Sixteen memory sockets are on the system board, with eight channels per CPU, two sockets per
channel.
For maximum memory performance, evenly distribute total desired memory capacity across
all operational channels. Proper individual DIMM capacity selection is essential to maximizing
performance.
Platform capabilities
System speed is determined by several factors:
● For 1 DIMM per channel configurations, the max memory speed is 4800 MHz.
● For 2 DIMM per channel configurations, the max memory speed is 4400 MHz.
Memory will operate at the speed of the slowest rated installed processor or DIMM.
Mixing of DIMMs in a system
● Mixing of x4 DRAMs with x8 DRAMs is not supported.
● 16 GB and 32 GB RDIMMs supported by HP are x8 and can be mixed in a system.
● 64 GB RDIMMs supported by HP are x4 and cannot be mixed with other sized DIMMs in a system.
