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 1866 MT/s, 1600 MT/s, 1333 MT/s, 1066 MT/s, or 800 MT/s depending on:

???DIMM type (UDIMM, RDIMM, or LRDIMM)

NOTE: PowerEdge R720xd with 3.5 inch hard-drive configuration does not support LRDIMMs due to thermal limitations.

???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.

Figure 17. Memory socket locations

Memory channels are organized as follows:

???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.

???Up to three LRDIMMs can be populated regardless of rank count.

???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 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 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.

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.

Sample memory configurations

The following tables show sample memory configurations for one and two processor configurations that follow the appropriate memory guidelines stated in this section.

NOTE: 16 GB quad-rank RDIMMs are not supported.

NOTE: 1R, 2R and 4R in the following tables indicate single-, dual-, and quad-rank DIMMs respectively.

NOTE: To ensure proper system cooling, you must install a processor blank and a heat-sink blank in any empty processor socket.

Removing A Processor

1.Before upgrading your system, download the latest system BIOS version from support.dell.com and follow the instructions included in the compressed download file to install the update on your system.

NOTE: You can update the system BIOS using the Lifecycle Controller.

2.Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet. When disconnected from the power source, press and hold the power button for three seconds to fully drain the system of stored power prior to removing the cover.

3.Open the system.

4.Remove the cooling shroud.

WARNING: The heat sink and processor are hot to the touch for some time after the system has been powered down. Allow the heat sink and processor to cool before handling them.

CAUTION: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper thermal conditions.

5.Using a #2 Phillips screwdriver, loosen one of the heat-sink retention sockets. Wait 30 seconds for the heat sink to loosen from the processor.

6.Loosen the second heat-sink retention socket.

7.Lift the heat sink away from the processor and set the heat sink aside.

NOTE: After removing the processor, place it in an antistatic container for reuse, return, or temporary storage. Do not touch the bottom of the processor. Touch only the side edges of the processor.

Installing A Processor

NOTE: If you are installing a single processor, it must be installed in socket CPU1.

NOTE: You can update the system BIOS using the Lifecycle Controller.

3.Open the system.

4.Remove the cooling shroud.

WARNING: The heat sink and processor are hot to the touch for some time after the system has been powered down. Allow the heat sink and processor to cool before handling them.

CAUTION: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper thermal conditions.

5.Remove the heat sink/heat-sink blank and processor/processor blank, as applicable.

NOTE: The procedure to remove the heat-sink blank or processor blank is similar to removing a heat-sink or processor.

6.Unpack the new processor.

7.Align the processor with the socket keys on the ZIF socket.

CAUTION: Positioning the processor incorrectly can permanently damage the system board or the processor. Be careful not to bend the pins in the socket.

CAUTION: Do not use force to seat the processor. When the processor is positioned correctly, it engages easily into the socket.

8.With the release levers on the processor socket in the open position, align pin 1 of the processor, using pin 1 position guide on the socket, as reference and set the processor lightly in the socket.

9.Close the processor shield.

10.Rotate the socket-release lever near the lock icon until it is locked in position.

11.Similarly, rotate the socket-release lever near the unlock icon until it is locked in position.

12.Using a clean lint-free cloth, remove the thermal grease from the heat sink.

CAUTION: Applying too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket.

13.Open the grease applicator included with your processor kit and apply all of the thermal grease in the applicator to the center of the topside of the new processor.

14.Place the heat sink on the processor.

15.Using a #2 Phillips screwdriver, tighten the heat-sink retention sockets.

16.Install the cooling shroud.

17.Close the system.

18.Reconnect your system and peripherals to their electrical outlets, and turn on the system.

19.Press <F2> to enter the System Setup and check that the processor information matches the new system configuration.

20.Run the system diagnostics to verify that the new processor operates correctly.

Power Supplies

Your system supports either:

???Two 495 W, 750 W, or 1100 W AC power supply modules or

???Two 750 W or 1100 W DC power supply modules

NOTE: Titanium power supply is nominally rated for 200 VAC to 240 VAC input only.

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.

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 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.

Removing An AC Power Supply

CAUTION: The system requires one power supply for normal operation. On power-redundant systems, remove and replace only one power supply at a time in a system that is powered on.

NOTE: You may have to unlatch and lift the optional cable management arm if it interferes with power supply removal. For information about the cable management arm, see the system???s rack documentation.

1.Disconnect the power cable from the power source and the power supply you intend to remove and remove the cables from the strap.

2.Press the release latch and slide the power supply out of the chassis.

Installing An AC Power Supply

1.Verify that both the power supplies are the same type and have the same maximum output power.

NOTE: The maximum output power (shown in Watts) is listed on the power supply label.

2.If applicable, remove the power supply blank.

3.Slide the new power supply into the chassis until the power supply is fully seated and the release latch snaps into place.

NOTE: If you unlatched the cable management arm, re-latch it. For information about the cable management arm, see the system???s rack documentation.

4.Connect the power cable to the power supply and plug the cable into a power outlet.

CAUTION: When connecting the power cable, secure the cable with the strap.

NOTE: When installing, hot-swapping, or hot-adding a new power supply, allow several seconds for the system to recognize the power supply and determine its status. The power-supply status indicator turns green to signify that the power supply is functioning properly.
