Population rules
When installing memory modules, observe the following population rules:
Use only HP memory modules listed in this document.
Advanced ECC is not available if x4 and x8 memory modules are mixed in channels (A and B), (C and D), or both, but
standard ECC is still available. Advanced ECC is available if x4 and x8 memory modules are mixed in memory channels (A
and C), (B and D), or both.
While adhering to the memory population rules ("Population rules" - see above), performance can be improved by following the
guidelines below:
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 all 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.
Advanced Memory Protection (AMP) mode Online Spare Memory has further requirements beyond these listed above. Please refer to
the user guide for additional memory configuration requirements
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 menu > Advanced Power Management Options menu > Maximum Memory
Bus Frequency menu.
