Memory Module Hewlett Packard Enterprise DDR3 4GB 1600Mhz

The Hewlett Packard Enterprise DDR3 4GB 1600Mhz memory module (MPN: B4U36AA-RFB, EAN: 5712505063637) is a single 4GB DDR3 DIMM operating at 1600MHz designed for use in compatible HP/ HPE systems. It provides additional system memory to improve multitasking and data access speed for servers and workstations that accept DDR3-1600 modules. The module is intended as a direct memory upgrade or replacement component and supports typical DDR3 signaling and form factor standards used in compatible systems.

Advantages

This 4GB DDR3-1600 module offers a balance of capacity and speed for systems limited to DDR3 memory, delivering consistent performance for standard server and workstation workloads. The module’s 1600MHz operating frequency helps reduce memory-related bottlenecks compared with lower-frequency DDR3 parts, while the 4GB capacity is suitable for adding modest additional RAM without major system changes. The HP/HPE part identification ensures compatibility guidance for systems supported by that manufacturer.

Suitable for

• Upgrading memory in servers or workstations that accept DDR3 1600MHz DIMMs
• Increasing available RAM for multitasking and application responsiveness
• Replacing a faulty or missing 4GB DDR3 module in compatible HP/HPE systems
• Use in environments where DDR3 memory is specified by the server or motherboard vendor

How to use

Before installation, power down the system and disconnect all power sources. Consult the system or motherboard manual to confirm supported memory types, maximum capacity, and slot population rules. Ground yourself to avoid electrostatic discharge and insert the module into a compatible DDR3 DIMM slot until the retention clips engage. After installation, reconnect power and enter the system BIOS/UEFI to confirm the new memory is recognized and operating at the expected speed. Follow any vendor-specific procedures if installing in a server platform that requires memory population compliance or firmware updates.

Usage recommendations

Use this HP-branded DDR3 4GB 1600MHz module in systems explicitly listed by the system or motherboard vendor as supporting DDR3-1600 DIMMs. Match module specifications (speed, voltage, ECC/non-ECC, buffered/registered) to existing modules when installing multiple sticks to maintain system stability. For critical servers, follow HP/HPE guidance on memory configuration, mixing rules, and warranty considerations.
