## Long description

The Dell 16 GB DDR5 6400 MT/s 1 x 16 GB 288-pin DIMM (AD277158) is a server-grade memory module designed to increase system bandwidth and responsiveness in compatible servers and workstations. This single-module configuration provides 16 GB of DDR5 memory on a 288-pin DIMM platform running at an effective data rate of 6400 MT/s, delivering higher transfer rates and improved power efficiency compared with previous DDR generations. The module is intended for system upgrades, capacity expansion, and replacement of faulty memory to maintain stable operation in multi-user and high-throughput environments.
Advantages
This DDR5 memory module offers increased data transfer speed and higher bandwidth at 6400 MT/s, which helps reduce latency in memory-intensive applications. Built to server standards, it provides improved power efficiency and stability compared with older DDR modules. The 288-pin DIMM form factor ensures compatibility with standard DDR5 server slots, and the single 16 GB module allows flexible memory expansion without replacing existing modules.
Suitable for
Upgrading server or workstation memory to improve multitasking and throughput
Replacing a defective DDR5 DIMM in compatible systems
Expanding memory capacity for virtualization, databases, or compute-intensive workloads
Key specifications
Capacity: 16 GB
Memory type: DDR5
Data rate: 6400 MT/s
Form factor: 288-pin DIMM
How to use
Power off the server or workstation and disconnect all power sources before installation. Open the system chassis according to the manufacturer’s service instructions to access the memory sockets. Align the notch on the 288-pin DIMM with the corresponding slot keyed in the memory socket, insert the module firmly until the retention clips engage, and ensure it is seated evenly. After installation close the chassis, reconnect power, and start the system. Verify that the BIOS/UEFI recognizes the new 16 GB DDR5 module and that the system reports the correct frequency and capacity.
Usage recommendations
Install memory modules in matched pairs or according to the server motherboard’s recommended population guidelines to maximize performance and enable multi-channel operation. Check system documentation for supported DDR5 speeds and capacity limits, and update firmware or BIOS if necessary for full compatibility with 6400 MT/s operation.
