System Memory

Your system supports DDR3 registered DIMMs (RDIMMs) and meets the DDR3 and DDR3L voltage specifications.

NOTE: MT/s indicates DIMM speed in MegaTransfers per second.

Memory bus operating frequency can be 1600 MT/s, 1333 MT/s, 1066 MT/s, or 800 MT/s depending on:

• DIMM configuration (number of ranks)

• maximum frequency of the DIMMs

• number of DIMMs populated per channel

• DIMM operating voltage

• system profile selected (for example, Performance Optimized, Custom, or Dense Configuration Optimized)

• maximum supported DIMM frequency of the processors

The system contains 24 memory sockets split into two sets of 12 sockets, one set per processor. Each 12-socket set is
organized into four channels. In each channel, the release levers of the first socket are marked white, the second socket
black, and the third socket green.

NOTE: DIMMs in sockets A1 to A12 are assigned to processor 1 and DIMMs in sockets B1 to B12 are assigned to
processor 2.

34

Figure 10. Memory Socket Locations

Memory channels are organized as follows:

Processor 1 channel 0: slots A1, A5, and A9

channel 1: slots A2, A6, and A10

channel 2: slots A3, A7, and A11

channel 3: slots A4, A8, and A12

Processor 2 channel 0: slots B1, B5, and B9

channel 1: slots B2, B6, and B10

General Memory Module Installation Guidelines

This system supports Flexible Memory Configuration, enabling the system to be configured and run in any valid chipset
architectural configuration. The following are the recommended guidelines for best performance:

• x4 and x8 DRAM based DIMMs can be mixed. For more information, see Mode-Specific Guidelines.

• Up to two quad-rank RDIMMs and up to three dual- or single-rank RDIMMs can be populated per channel.
When a quad-rank RDIMM is populated in the first slot with white release levers, the third DIMM slot in the
channel with green release levers cannot be populated.

• Populate DIMM sockets only if a processor is installed. For single-processor systems, sockets A1 to A12 are
available. For dual-processor systems, sockets A1 to A12 and sockets B1 to B12 are available.

• Populate all sockets with white release tabs first, then black, and then green.

• Do not populate the third DIMM socket in a channel with green release tabs, if a quad-rank RDIMM is populated
in the first socket with white release tabs.

• Populate the sockets by highest rank count in the following order — first in sockets with white release levers,
then black, and then green. For example, if you want to mix quad-rank and dual-rank DIMMs, populate quad­rank DIMMs in the sockets with white release tabs and dual-rank DIMMs in the sockets with black release tabs.

• In a dual-processor configuration, the memory configuration for each processor should be identical. For
example, if you populate socket A1 for processor 1, then populate socket B1 for processor 2, and so on.

• Memory modules of different sizes can be mixed provided that other memory population rules are followed (for
example, 2 GB and 4 GB memory modules can be mixed).

• Populate four DIMMs per processor (one DIMM per channel) at a time to maximize performance.

• If memory modules with different speeds are installed, they will operate at the speed of the slowest installed
memory module(s) or slower depending on system DIMM configuration.

Mode-Specific Guidelines

Four memory channels are allocated to each processor. The allowable configurations depend on the memory mode
selected.

NOTE: x4 and x8 DRAM based DIMMs can be mixed providing support for RAS features. However, all guidelines for
specific RAS features must be followed. x4 DRAM based DIMMs retain Single Device Data Correction (SDDC) in
memory optimized (independent channel) mode. x8 DRAM based DIMMs require Advanced ECC mode to gain
SDDC.

The following sections provide additional slot population guidelines for each mode.

Advanced ECC (Lockstep)

Advanced ECC mode extends SDDC from x4 DRAM based DIMMs to both x4 and x8 DRAMs. This protects against single
DRAM chip failures during normal operation.

Memory installation guidelines:

• Memory modules must be identical in size, speed, and technology.

• DIMMs installed in memory sockets with white release tabs must be identical and similar rule applies for
sockets with black and green release tabs. This ensures that identical DIMMs are installed in matched pairs ­for example, A1 with A2, A3 with A4, A5 with A6, and so on.

NOTE: Advanced ECC with Mirroring is not supported.

36

Memory Optimized (Independent Channel) Mode

This mode supports SDDC only for memory modules that use x4 device width and does not impose any specific slot
population requirements.

Memory Sparing

NOTE: To use memory sparing, this feature must be enabled in the System Setup.

In this mode, one rank per channel is reserved as a spare. If persistent correctable errors are detected on a rank, the
data from this rank is copied to the spare rank and the failed rank is disabled.

With memory sparing enabled, the system memory available to the operating system is reduced by one rank per
channel. For example, in a dual-processor configuration with sixteen 4 GB dual-rank DIMMs, the available system
memory is: 3/4 (ranks/channel) × 16 (DIMMs) × 4 GB = 48 GB, and not 16 (DIMMs) × 4 GB = 64 GB.

NOTE: Memory sparing does not offer protection against a multi-bit uncorrectable error.

NOTE: Both Advanced ECC/Lockstep and Optimizer modes support Memory Sparing.

Memory Mirroring

Memory Mirroring offers the strongest DIMM reliability mode compared to all other modes, providing improved
uncorrectable multi-bit failure protection. In a mirrored configuration, the total available system memory is one half of
the total installed physical memory. Half of the installed memory is used to mirror the active DIMMs. In the event of an
uncorrectable error, the system will switch over to the mirrored copy. This ensures SDDC and multi-bit protection.

Memory installation guidelines:

• Memory modules must be identical in size, speed, and technology.

• DIMMs installed in memory sockets with white release tabs must be identical and similar rule applies for
sockets with black and green release tabs. This ensures that identical DIMMs are installed in matched pairs ­for example, A1 with A2, A3 with A4, A5 with A6, and so on.

Memory Configuration

The following table shows the supported memory configuration for a two processor configuration that follows the
appropriate memory guidelines stated in this section.

Power Supplies

Your system supports two 750 W power supply modules.
When two identical power supplies are installed, the power supply configuration is redundant (1 + 1). In redundant

mode, power is supplied to the system equally from both power supplies to maximize efficiency.

NOTE: If two power supplies are used, they must be of the same type and have the same maximum output power.

68

Power Supply Hot Spare Feature

Your system supports the Hot Spare feature that significantly reduces the power overhead associated with power
supply redundancy.

When the Hot Spare feature is enabled, a redundant power supply is switched to a sleep state. The active power supply
supports 100% of the load, thus operating at higher efficiency. The redundant power supply in the sleep state monitors
output voltage of the active power supply. If the output voltage of the active power supply drops, the redundant power
supply in the sleep state returns to an active output state.

The active power supply can also activate a sleeping power supply if having both power supplies active is more efficient
than having the redundant power supply in a sleep state. The power supply defaults are to wake both power supplies if
the load on the active power supply is greater than 50% and to sleep the redundant power supply if the load falls below
20%.

You can configure the Hot Spare feature using the iDRAC settings. For more information on iDRAC settings, see the

iDRAC7 User's Guide

at dell.com/support/manuals.
