Dell DIMM, 16GB, DDR4, 2400MHz, 2RX8, 8G, HNDJ7 JJD1D-RFB

Dell DIMM, 16GB, DDR4, 2400MHz, 2RX8, 8G, HNDJ7 JJD1D-RFB is a 16GB DDR4 memory module designed for use in compatible Dell systems. The module operates at a data rate of 2400 MHz and uses a dual-rank (2RX8) organization. It is intended to provide increased memory capacity for multitasking, server or workstation workloads and to maintain stable system performance when installed in supported Dell platforms.

Advantages

This Dell 16GB DDR4 module offers a balance of capacity and frequency suitable for mainstream servers and workstations. The 2400 MHz speed provides reliable data throughput for typical business and productivity tasks while the 2RX8 dual-rank design can improve memory access efficiency in systems that support rank interleaving. The module is manufactured to Dell specifications (MPN: JJD1D-RFB) and carries the EAN 5715063003015, ensuring compatibility tracking and inventory identification.

Suitable for

• Increasing system memory in Dell servers and workstations compatible with DDR4-2400 modules
• Improving multitasking capacity for business applications and virtual machines
• Replacing or upgrading existing DIMMs with matching DDR4-2400, 2RX8 modules
• Deployments requiring 16GB capacity per memory slot for balanced memory configurations

How to use

Power down the system and disconnect it from the power source before handling memory modules. Consult the Dell system documentation to identify compatible DIMM slots and supported configurations. Ground yourself to prevent electrostatic discharge and insert the DIMM into the appropriate slot until the latches engage. After installation, reconnect power and start the system; verify that the BIOS/UEFI recognizes the new 16GB module and that system memory reporting matches the expected capacity and configuration.

Usage recommendations

For optimal performance, install memory modules in matched pairs or according to the server/workstation manufacturer’s channel population guidelines. Use modules with the same capacity, speed and rank characteristics to avoid configuration conflicts. Check Dell support documentation or system compatibility lists to ensure firmware and platform support for DDR4-2400, 2RX8 modules before deployment.
