● System ECC is supported on unbuffered ECC DIMMs NOTE: The system might not operate properly if you install unsupported memory modules. There are four memory sockets on the system board, with two channels per CPU, two sockets per channel. The sockets are labeled DIMM1, DIMM2, DIMM3, and DIMM4. 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 Although the memory modules can run up to 4800 Mbps, the current platform supports a maximum memory speed of 4400 Mbps. System speed is determined by several factors.

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. ● Move similar modules into the same channel (memory slots 1 and 2) and install new modules together in the second channel (slots 3 and 4). Memory features ● Single-bit errors are automatically corrected. ● Detected multi-bit errors cause the system to immediately reboot and halt with an F1 prompt error message. NOTE: Although HP does support non-ECC memory on this platform, non-ECC memory does not fully detect or correct single-bit or multi-bit errors, which can cause instability or corruption of data in the platform. Loading rules ● Each channel includes two sockets. Load DIMM slots 1 and 3 first, then 2 and 4. Do not load slot 2 unless slot 1 is loaded. Do not load slot 4 unless slot 3 is loaded.

System ECC is supported on unbuffered ECC DIMMs
NOTE:
The system might not operate properly if you install unsupported memory modules.
There are four memory sockets on the system board, with two channels per CPU, two sockets per
channel. The sockets are labeled DIMM1, DIMM2, DIMM3, and DIMM4.
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
Although the memory modules can run up to 4800 Mbps, the current platform supports a maximum
memory speed of 4400 Mbps.
System speed is determined by several factors.

* Actual memory speed is dependent on the processor.
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.
●
Move similar modules into the same channel (memory slots 1 and 2) and install new modules
together in the second channel (slots 3 and 4).
Memory features
●
Single-bit errors are automatically corrected.
●
Detected multi-bit errors cause the system to immediately reboot and halt with an F1 prompt error
message.
NOTE:
Although HP does support non-ECC memory on this platform, non-ECC memory does not fully
detect or correct single-bit or multi-bit errors, which can cause instability or corruption of data in the
platform.
Loading rules
●
Each channel includes two sockets. Load DIMM slots 1 and 3 first, then 2 and 4. Do not load slot 2
unless slot 1 is loaded. Do not load slot 4 unless slot 3 is loaded.
