BIOS Memory Configurations

The server supports the following Advanced Memory Protection (AMP) options in the system BIOS to optimize serveravailability.

Advanced ECC supporting up to 16 GB of active memory using 2-GB FBDIMMs.
Online Spare Memory providing additional protection against degrading FBDIMMs supporting up to12 GB of active memory and 4 GB of online spare memory utilizing 2-GB FBDIMMs.
Mirrored Memory providing protection against failed FBDIMMs supporting up to 8 GB of activememory and 8 GB of mirrored memory utilizing 2-GB FBDIMMs.

Maximum memory capacities for all AMP modes will increase with the availability of 4-GB and 8-GBFBDIMMs, including a maximum of 64 GB in Advanced ECC mode. For the latest memory configurationinformation, refer to the QuickSpecs on the HP website.

The Advanced Memory Protection option is configured in ROM Based Setup Utility (RBSU). By default, the server is set to AdvancedECC mode. For more information, refer to HP ROM-Based Setup Utility information on page 68 of the Proliant DL360 G5 User Guide.

NOTE: If the configuredAMP mode is not supported by the installed FBDIMM configuration, the system boots in Advanced ECCmode.

The following configuration requirements apply to all AMP modes:

FBDIMMS must be ECC Registered DDR-2 SDRAM FBDIMMs.
FBDIMMs must be installed in pairs.
FBDIMM pairs in a memory bank must have identical HP part numbers.
FBDIMMS must be populated as specified for each AMP memory mode.

The memory subsystem for this server is divided into two branches. Each memory branch is essentially aseparate memory controller. The FBDIMMs map to the two branches as indicated in the following table:

Branch 1
FBDIMM 5B
FBDIMM 7B
FBDIMM 6D
FBDIMM 8D

This multi-branch architecture provides enhanced performance in Advanced ECC mode. The concept ofmultiple branches is important for the operation of online spare mode and mirrored memory mode.

If the server contains more than 4 GB of memory, consult the operating system documentation aboutaccessing the full amount of installed memory.

Advanced ECC memory configuration requirements

Advanced ECC memory is the default memory protection mode for this server. In Advanced ECC, theserver is protected against correctable memory errors. The server provides notification if the level ofcorrectable errors exceeds a pre-defined threshold rate. The server does not fail because of correctablememory errors. Advanced ECC provides additional protection over Standard ECC because it is possibleto correct certain memory errors that would otherwise be uncorrectable and result in a server failure.

Whereas standard ECC can correct single-bit memory errors, Advanced ECC can correct single-bitmemory errors and multi-bit memory errors if all failed bits are on the same DRAM device on theFBDIMM.In addition to general configuration requirements, Advanced ECC memory also has the followingconfiguration requirements:

FBDIMMs must be installed in pairs.
FBDIMMs must be installed in sequential order, beginning with bank A.

In Advanced ECC mode, FBDIMMs must be populated as specified in the following table:

Bank A	Bank C
1A and 3A	2C and 4C
1	-	-
X	-
3	X	-
X	X

Online spare FBDIMM configuration requirements

Online spare memory provides protection against degrading FBDIMMs by reducing the likelihood ofuncorrectable memory errors. This protection is available without any operating system support.

An understanding of single-rank and dual-rank FBDIMMs is required to understand memory usage inonline spare mode. FBDIMMs can either be single-rank or dual-rank. Certain FBDIMM configurationrequirements are based on these classifications. A dual-rank FBDIMM is similar to having two single-rankFBDIMMs on the same module. Although only a single FBDIMM module, a dual-rank FBDIMM acts as twoseparate FBDIMMs. The purpose of dual-rank FBDIMMs is to provide the largest capacity FBDIMM for the current DRAM technology. If the current DRAM technology allows for 2-GB single-rank FBDIMMs, a dualrankFBDIMM using the same technology would be 4-GB.

In online spare mode, a single rank of memory acts as the spare memory. For single-rank FBDIMMs, theentire FBDIMM acts as the spare memory. For a dual-rank FBDIMM, only half of the FBDIMM acts as thespare memory while the other half is available for operating system and application usage.

If one of the non-spare FBDIMMs receives correctable memory errors at a higher rate than a specificthreshold, the server automatically copies the memory contents of the degraded rank to the online sparerank. The server then deactivates the failing rank and automatically switches over to the online spare.Because FBDIMMs that experience a high rate of correctable memory errors also have a higherprobability of receiving an uncorrectable memory error, this configuration reduces the likelihood ofuncorrectable memory errors that would result in server downtime.

Each branch is made up of two banks:

Branch 0 contains banks A and C
Branch 1 contains banks B and D

Online spare is performed per branch of the memory controller. For a server with both branchespopulated, two ranks are used for online spare memory. One branch can fail over to the associatedonline spare while the other branch is still protected.

Online spare FBDIMM configuration requirements (in addition to general configuration requirements)

When only bank A is being used, it must be fully populated with dual-rank FBDIMMs.
If banks A and C are being used, they must be fully populated.
If installed, bank A and bank C must contain FBDIMMs with identical part numbers.
If installed, bank B and bank D must also contain FBDIMMs with identical part numbers.

In online spare mode, FBDIMMs must be populated as specified in the following table:

Bank A	Bank C
1A and 3A	2C and 4C
1*	-	-
X	X
3	X	X
* Configuration 1 is only supported if using bank A, populated with dual-rank FBDIMMs.

NOTE: After installing FBDIMMs, use RBSU to configure the system for online spare memory support

Mirrored memory FBDIMM configuration requirements

Mirroring provides protection against uncorrectable memory errors that would otherwise result in serverdowntime.Mirroring is performed on the branch level. Branch 0 and branch 1 mirror each other.

Each branch maintains a copy of all memory contents. Memory writes go to both branches. Memoryreads come from only one of the two branches (unless an uncorrectable error occurs). If a memory readon one branch returns incorrect data due to an uncorrectable memory error, the system automaticallyretrieves the proper data from the other branch. A branch is not necessarily disabled (thus losingmirroring protection) because of a single uncorrectable error. Mirroring protection is not lost because oftransient and soft uncorrectable errors, resulting in systems that maintain mirroring protection (and thusimproved uptime) unless there is a failure of both branches.

Mirrored memory FBDIMMs configuration requirements (in addition to general configuration requirements)

Banks A and B must be fully populated.
Bank A and bank B must contain FBDIMMs with identical part numbers. If installed, bank C and bank D must also containFBDIMMs with identical part numbers.

When using mirrored memory mode, FBDIMMs must be populated as specified in the following table:

Bank A	Bank C
1A and 3A	2C and 4C
1	X	-
X	X

NOTE: After installing FBDIMMs, use RBSU to configure the system for mirrored memory support.

DDR3 memory population guidelines

NOTE: Memory configurations listed do not apply to Factory Integrated Models.

Click here to use Online DDR3 Memory Configuration Tool for detailed memory configuration rules and guidelines.

Some DIMM installation guidelines are summarized below:

For servers with eighteen (18) memory slots:
- There are three (3) channels per processor; six (6) channels per server
- There are three (3) DIMM slots for each memory channel; eighteen (18) total slots
- Memory channel 1 consists of the three (3) DIMMs that are closest to the processor
- Memory channel 3 consists of the three (3) DIMMs that are furthest from the processor
DIMM slots that are white should be populated first
Do not mix Unbuffered memory (UDIMMs) with Registered memory (RDIMMs)
Do not install DIMMs if the corresponding processor is not installed
If only one processor is installed in a 2CPU system, only half of the DIMM slots are available
To maximize performance, balance the total memory capacity between all installed processors
It is not required, but it is recommended to load the channels similarly if possible
If any Quad rank DIMMs are installed, all channels are limited to only 2 DIMMs per channel.
You can only install two quad-rank DIMMs per channel
You can only install two UDIMMs per channel; if available, the third slot in the channel must remain empty
Populate DIMMs from heaviest load (quad-rank) to lightest load (single-rank) within a channel
Heaviest load (DIMM with most ranks) within a channel goes furthest from the chipset
For memory mirroring mode, channel 3 must be unpopulated. Channels 1 and 2 are populated identically
For lock-step mode, channel 3 must be unpopulated. DIMMs in channels 1 and 2 will be installed in pairs. The paired slotswill be 1,4; 2,5; 3;6 on a 3DPC system or 1,4; 2,5; on a 2DPC system
If mixing DIMM voltage is a requirement, please note that the DIMMs will run at 1.5V since all 1.35V are capable ofsupporting 1.5V operations

DIMM Type		Unbuffered with ECC DIMMs(UDIMMs)
SingleRank (1R)	Quad Rank (4R)		Dual Rank (2R)
4GB	4GB	8GB	16GB	2GB

LV/Reg	Reg	LV/Reg	Reg	Reg
Slots that can be populated
18	18	18	12	12
Maximum capacity (GB)

1 DIMM Per Channel	1333	1067	1067	1333	1333
1333¹	1333¹	1333¹	800	1333
3 DIMM Per Channel	800	800	n/a	n/a	n/a
NOTE: supported with ROM update via ROM Based Setup Utility (RBSU). UDIMM support is only on 12-slot servers

NOTE:

Mixing DIMM speeds is allowed, but the system processor speed rules always override the DIMM capabilities
If you do mix DIMM speeds, the memory bus will default to the minimum clock rate of all DIMMs in the system - even if theslower DIMM is on the other processor
If you install 1x 1066 MHz DIMM in channel 1 and 1x 1333 MHz DIMM in channel 2, you still run at 1066MHz
If you install 1x 1066 MHz DIMM in channel 1 and 5x 1333 MHz DIMMs with 1 DIMM Per Channel (DPC) in each of the otherchannels, you run at 1066 MHz
If you install 3DPC in one channel (if applicable) and 1DPC in all other channels, you run at 800 MHz
95 Watt CPU's are required for 1333MHz DIMM speeds. All other CPU's are capable of up to 1067 MHz
References to the above MHz speeds are for the various speeds of DDR3 DIMMs; 1333 refers to DDR3-1333, etc.
