HP ProLiant DL385 - Manual (Page 32)

Memory modules may be installed one at a time per processor, but installing two at a time per processor provides for
additional performance, installing four at a time per processor provides for better performance, and installing equal amounts of
memory for both processors provides for best performance.
Install all memory modules of the same speed on the same processor for best performance.
Install all memory modules of the same voltage on the same processor for best power.
Memory bus speed Memory bus speed Memory bus speed Memory bus speed
Depending on the quantity and native speed of memory modules installed, memory bus speeds can be 1333 MHz, 1066 MHz, 800
MHz, or 667 MHz. Memory bus speeds can be different for each processor.
To determine memory bus speeds, do the following:
Within RBSU, select the Power Management Options Power Management Options Power Management Options Power Management Options menu > Advanced Power Management Options Advanced Power Management Options Advanced Power Management Options Advanced Power Management Options menu > Maximum Memory Maximum Memory Maximum Memory Maximum Memory
Bus Frequency Bus Frequency Bus Frequency Bus Frequency menu.
Select one of the following menu options:
Auto (default) Auto (default) Auto (default) Auto (default) - The memory bus speed is set to what is shown in the following table. If the native speed of the installed
memory module is slower than the memory bus speed, the memory bus speed is set to the memory module native speed
