CAUTION: AC power supplies support both 220 V and 110 V input voltages with the
exception of Titanium power supplies, which support only 220 V. When two identical
power supplies receive different input voltages, they can output different wattages, and
trigger a mismatch.

Page 18
You must select the boot mode in the Boot Mode field of the Boot Settings screen of System Setup. Once you specify the
boot mode, the system boots in the specified boot mode and you then proceed to install your operating system from that
mode. Thereafter, you must boot the system in the same boot mode (BIOS or UEFI) to access the installed operating
system. Trying to boot the operating system from the other boot mode will cause the system to halt at startup.
NOTE: Operating systems must be UEFI-compatible to be installed from the UEFI boot mode. DOS and 32-bit
operating systems do not support UEFI and can only be installed from the BIOS boot mode.
NOTE: For the latest information on supported operating systems, go to dell.com/ossupport.

System Memory
Your system supports DDR3 unbuffered ECC DIMMs (ECC UDIMMs), registered DIMMs (RDIMMs), and load reduced
DIMMs (LRDIMMs). It supports DDR3 and DDR3L voltage specifications.
NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
Memory bus operating frequency can be either 800 MT/s, 1066 MT/s , 1333 MT/s, 1600 MT/s, or 1866 MT/s depending on
the:
• DIMM type (UDIMM, RDIMM, or LRDIMM)
• 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 48 memory sockets split into four 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, B1 to B12 to processor 2, C1 to C12 to processor
3, and D1 to D12 to processor 4.

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:
• UDIMMs, RDIMMs, and LRDIMMs must not be mixed.
• x4 and x8 DRAM based DIMMs can be mixed. For more information, see Mode-Specific Guidelines.
• A maximum of two UDIMMs can be populated in a channel.
• Up to two quad-rank RDIMMs and up to three dual- or single-rank RDIMMs can be populated per channel.
• Up to three LRDIMMs can be populated regardless of rank count.
• Populate DIMM sockets only if a processor is installed. For dual-processor systems, sockets A1 to A12 and B1 to
B12 are available. For four-processor systems, sockets A1 to A12, B1 to B12, C1 to C12, and D1 to D12 are available.
• 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, to mix quad-rank and dual-rank DIMMs, populate quad-rank 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 must be identical. For example, if
you populate socket A1 for processor 1, then you must populate socket B1 for processor 2.
• 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 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.
46
Page 47
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.
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 levers 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.

The following tables show sample memory configurations that follow the appropriate memory guidelines stated in this
section.

Power Supplies
Your system supports either:
• Two 750 W or 1100 W AC power supply modules
• Two 750 W Titanium efficiency power supply modules
• Two 1100 W DC power supply modules
NOTE: Titanium power supply is nominally rated for 200 VAC to 240 VAC input only.
NOTE: When two identical power supplies are installed, power supply redundancy (1+1 – with redundancy or 2+0
– without redundancy) is configured in system BIOS. In redundant mode, power is supplied to the system equally
from both power supplies when Hot Spare is disabled. When Hot Spare is enabled, one of the PSUs will be put into
standby when system utilization is low in order to maximize efficiency.
When only one power supply is installed, the power supply configuration is non-redundant (1 + 0). Power is supplied to
the system only by the single power supply.
NOTE: If two power supplies are used, they must be of the same type and have the same maximum output power.
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
88
Page 89
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.
