Oracle Sun 7064941 Memory Riser Board

Description

The Oracle Sun 7064941 is a Memory Riser Board designed specifically for the SPARC T5-2 enterprise server. It provides the physical and electrical interface required to connect DIMMs to the server’s processor memory subsystem.

Oracle’s SPARC T5-2 documentation states that each memory riser contains four DIMM slots. In a two-processor T5-2 configuration, the system uses eight memory risers, while a one-processor configuration uses four memory risers. Four memory risers are associated with each CPU.

The 7064941 is listed in the T5-2 component documentation as the Memory Riser, while 7064940 is identified as the corresponding Memory Riser Assembly. The assembly includes the 7049156 riser carrier, whereas 7064941 refers to the riser board itself.

The memory riser is designed to accommodate compatible DIMMs used by the SPARC T5-2. Oracle’s supported memory options include 8GB DDR3L-1600/PC3L-12800, 16GB DDR3L-1600/PC3L-12800, and 32GB DDR3L-1066/DDR3L-1333 modules, depending on the system configuration.

Oracle specifies strict memory population rules for the T5-2. Each memory-riser position must contain a riser, and all risers in a configuration must use DIMMs with matching rank, size, and type. In a half-populated configuration, two DIMMs are installed in the black connectors on each riser; in a fully populated configuration, all four DIMM connectors are populated.

Key Specifications

*Supported memory capacity and DIMM configuration depend on the specific SPARC T5-2 system configuration.

Key Features & Benefits

• Genuine Oracle/Sun SPARC server component
• Designed specifically for SPARC T5-2
• Provides four DIMM slots
• Supports the T5-2’s DDR3/DDR3L ECC memory architecture
• Enables high-density server memory configurations
• Designed for enterprise server environments
• Suitable for replacement of a damaged or failed memory riser
• Ideal for server refurbishment and maintenance
• Supports memory expansion when installed with compatible DIMMs
• Platform-specific design for reliable integration with the T5-2 motherboard

Memory Architecture

The SPARC T5-2 uses memory risers to connect system memory to its processor memory controllers. Oracle documents four memory risers per CPU, with the two-processor configuration containing eight risers in total. Each riser provides four DIMM connectors.

Oracle also specifies that the T5-2 cannot boot unless the required memory-riser slots are populated according to the supported configuration. All memory risers must contain DIMMs of the same rank, size, and type within the supported configuration.

Compatible Memory

The SPARC T5-2 supports several Oracle-qualified memory options, including:

• 8GB DDR3L-1600 / PC3L-12800
• 16GB DDR3L-1600 / PC3L-12800
• 32GB DDR3L-1066 / DDR3L-1333

The exact memory population must follow Oracle’s configuration rules for the target T5-2 system.

Assembly and Part Number Information

For inventory and purchasing purposes, it is important to distinguish the individual riser from the complete riser assembly:

• 7064941 — Memory Riser
• 7049156 — Riser Carrier
• 7064940 — Memory Riser Assembly
• 7306028 / 7312442 — Later memory-riser assembly configurations
• 7306029 — Memory Riser used with later assemblies

Oracle’s T5-2 component documentation confirms these relationships.

Recommended Applications

The Oracle 7064941 is suitable for:

• Oracle SPARC T5-2 servers
• Enterprise data centers
• Oracle Solaris environments
• Database servers
• Business-critical applications
• Server memory expansion
• Memory-riser replacement
• Server repair and refurbishment
• Enterprise hardware maintenance

Compatibility

Primary Compatible Platform:
Oracle Sun SPARC T5-2

Before installation, verify the existing FRU/part number, riser revision, carrier configuration, and DIMM compatibility. The 7064941 is the memory riser board, not the complete 7064940 memory-riser assembly.
