Note: The processor FSB frequency is not altered; only the internal core
frequency is changed. When entering the low power state, the processor first
switches to the lower bus to core frequency ratio and then transitions to the
lower voltage.
While in the Extended HALT state, the processor will process bus snoops.
For more information about power saving modes, refer to the Intel Xeon 7200
and 7300 Processor Series Datasheet:

Important: All changes you make within the BIOS affects the particular local
node only. Any changes you make must also be made on all nodes within a
multinode configuration. Although you may have different settings on different
nodes, it is not recommended.
3.2 Memory subsystem
The x3850 M2 and x3950 M2 systems allow you to add memory DIMMs to a
maximum of four memory cards.
3.2.1 Memory options
All memory modules you want to install in your x3850 M2 or x3950 M2 server
must be 1.8 V, 240-pin, PC2-5300 DDR II, registered SDRAM with ECC DIMMs.
The supported DIMM options are listed in Table 3-3:
