compatibility, performance, and reliability. Most third-party memory vendors

simply don’t do this or aren’t capable.

• HP Qualified Server Memory’s stringent requirements specifies only the

highest quality components from tier 1 suppliers. DRAM chips that don’t meet

HP standards get sold elsewhere.

DDR3 Memory population rules – Intel

General guidelines • Install DIMMs only if the corresponding processor is installed. • If only one processor is installed in a two processor system, only half of the DIMM slots are available. • To maximize performance, it is recommended to balance the total memory capacity between all installed processors

and load the channels similarly whenever possible. • When two processors are installed, balance the DIMMs across the two processors. • White DIMM slots denote the first slot to be populated in a channel. • Place the DIMMs with the highest number of ranks in the white slot when mixing DIMMs of different ranks on the same

channel. • Do not mix UDIMMs, RDIMMs or LRDIMMs. • Quad rank RDIMMs are not supported in HP ProLiant Gen8 servers. • LRDIMMs are capable of up to three DIMMs per channel. • RDIMMs operating at either 1.35V or 1.5V may be mixed in any order, but the system will power them at the higher

voltage. • DIMMs of different speeds may be mixed in any order; the server will select a common optimal speed. • The maximum memory speed is a function of the memory type, memory configuration, and processor model. • The maximum memory capacity is a function of the memory type and number of installed processors. • To realize the performance memory capabilities listed in this document, HP SmartMemory is required.

• There are four (4) channels per processor; eight (8) channels per server

• There are three (3) DIMM slots for each memory channel; eighteen (24) total slots

• Memory channels1 and 3 consists of the three (3) DIMMs that are furthest from the processor

• Memory channel 2 and 4 consists of the three (3) DIMMs that are closest to the processor

For more recommendations and guidelines visit:

Online configuration tool; www.hp.com/go/ddr3memory-configurator

For optimal performance, balance

DIMMs equally across all four

channels, starting farthest from the

CPUs.

• When one processor is installed, install DIMMs in sequential alphabetical order (A,B,C,D,E,F) and so forth.

• When two processors are installed, install DIMMs in sequential alphabetical order (P1-A, P2-A, P1-B, P2-B, P1-C, P2-C)

Reduce unplanned downtime

HP Advanced Memory Error Detection

• Average GB per server has grown by more than 500% over the last five years

• DRAM technology has evolved to support up to 4Gb (4 gigabit) per chip

• Ability to determine a system’s vulnerability to future memory errors has remained

unchanged for over 10 years

• New algorithm pinpoints error that may cause uncorrectable errors and unplanned

downtime

Memory technology cheat sheet

DDR3 is the third generation of Double Data Rate (DDR) SDRAM memory. It is a continuing evolution of DDR memory technology

that delivers higher speeds, lower power consumption and heat dissipation. It is an ideal memory solution for bandwidth hungry

systems equipped with multi-core processors.

Capacities available include 2, 4, 8, 16 & 32GB. HP DDR3 option kits consist of single DIMMs

DIMM type

• UDIMMs with ECC offer lower latency and power consumption than RDIMMs, but are more limited in capacity. Unbuffered with ECC identified with an E in

the manufacturer’s module name (example PC3-10600E).

• RDIMMs also have ECC and offer larger capacities than UDIMMs and include address parity protection. Registered identified with an R in the module

manufacturer’s name (example PC3-10600R).

ECC indicates Error Correct Code capabilities. Can correct single bit errors. Can detect but not correct multi-bit errors. Advanced

ECC allows correction of certain multi-bit errors.

Speed indicates the data rate of the DRAM chips and the Memory Module that uses those chips. Current Gen8 Memory offers two

base speeds;

• DDR3-1066 DRAM operates at 1066 Mbits/s. A DIMM with DDR3-1066 DRAM is called PC3-8500 (1066 x 8 Bytes ~= 8500 MBytes/s)

• DDR3-1333 DRAM operates at 1333 Mbits/s. A DIMM with DDR3-1333 DRAM is called PC3-10600 (1333 x 8 Bytes ~=10600 MBytes/s)

• DDR3-1600 DRAM operates at 1600 Mbits/s. A DIMM with DDR3-1600 DRAM is called PC3-12800 (1600 x 8 Bytes ~= 12800 MBytes/s)

• System realized speeds will depend on how the server is populated with memory.

28



Memory technology cheat sheet cont’d

Rank – DDR3 supports Single, Dual and Quad rank DIMMs. Rank refers to DRAM chips that are ganged together to provide 64

bits (8 Bytes) of data on the memory bus. All chips in a rank are controlled simultaneously by the same Chip Select, Address and

Command signals.

Data width – x4 and x8 indicate the number of data outputs per DRAM. Eight x8 DRAMs make one rank. Sixteen x4 DRAMs

make one rank. 64 bits in each case. For Gen8 memory, all RDIMMs are x4 only. UDIMMs are x8 only.

• Unbuffered ECC and Registered DIMMs will have: 9 DRAMs (x8) or 18 DRAMs (x4) per rank, with the additional DRAMs used for ECC.

Density – Describes the number of storage locations in a DRAM chip. DDR3 will launch with 1Gb and 2Gb-based DRAM. No

512Mb in DDR3.

Voltage – Over time, DDR3 memory will consist of three voltage ratings;

Standard at G6 announce (1.5V); G7 launched with Low Voltage (1.35V). Future: Ultra Low Voltage (TBD; ~1.25V)

DDR3 has lower power architecture, due to lower core voltage

• >25% power savings over DDR2 (DDR2-800 vs. DDR3-800)

• DDR3-1066 consumes less power than DDR2-800.

CAS latency – Column Address Strobe latency refers to the DRAM read response time in number of bus clocks from the Column

Address to the DRAM providing data on the memory bus. A lower number will yield a performance increase for most applications.
