Enable Node Interleaving (G6 servers)
Enabling Node Interleaving disables the NUMA architecture properties of the system. All operating
systems supported by this platform support NUMA architectures. In most cases, you can obtain optimum
performance by disabling Node Interleaving. When this option is enabled, memory addresses are
interleaved across the memory installed for each processor. When this option is enabled, some workloads
may see improved performance.
Memory Speed with 2 DIMMs per Channel (G6 servers)
This option configures the system to run DIMMs at 1333 MHz when up to two DIMMs are installed on a
memory channel, if all other requirements for 1333 MHz operation are met. This provides a performance
increase for most workloads. By default, the system will operate at a maximum 1066 MHz when two
DIMMs are installed on any memory channel. HP has validated this functionality with all HP DIMMs.
HP recommends that this setting remain at the default of 1066 MHz maximum when using DIMMs not
manufactured by HP.
