Notes: For the memory support on the Intel Xeon Max Series, which is with the high
bandwidth memory (HBM), please note the following:
1. CPU Only Mode: This mode is supported when the Intel Xeon Max Series is installed
with no DDR memory module. The feature of "Total Memory" on the Main screen of
the BIOS Setup utility displays the HBM size.
2. Cache Mode: This mode is supported when the Intel Xeon Max Series is installed
with the DDR memory module(s). The processor will be configured in the Two-Level
Memory mode (2LM), which is the default setting. The feature of "Total Memory" on
the Main screen of the BIOS Setup utility displays the size of DDR memory module(s)
installed in your system.
3. Flat Mode: This mode supports the One-Level Memory mode (1LM). Please go to
the BIOS Setup utility (Advanced > Chipset Configuration > North Bridge > Memory
Configuration) to set "Volatile Memory Mode" to 1LM. The feature of "Total Memory"
on the Main screen of the BIOS Setup utility displays the result of adding the HBM
size to the DDR size.
4. The total DDR size must be at least two times of the HBM size for each CPU socket.
