16 GB DDR5 4800 memory module

This 16 GB DDR5 DIMM runs at 4800 MT/s with a CAS latency of 40 and operates at 1.1 V. It uses a 2Rx8 unbuffered non-ECC design on a 288-pin form factor. The module is intended for desktops or workstations that require a single stick of DDR5 system memory. It is sold as a one-piece kit under part number CM2048644800DIMM.

Check motherboard DDR5 support and slot layout

Verify that your platform accepts DDR5 memory and that a free 288-pin DIMM slot is available. The board must be able to run at 4800 MT/s or will down-clock the module automatically. A 64-bit operating system is required to address more than 4 GB of memory. Mixing this stick with existing modules will force all memory to run at the speed of the slowest installed module or the CPU limit.

Upgrade from slower DDR5 or add capacity

This module replaces a lower-speed DDR5 DIMM or adds 16 GB to a system that has an empty slot. The jump is worthwhile when the current memory runs below 4800 MT/s or when total capacity limits multitasking performance. It does not suit builds that need ECC error correction or registered modules for server platforms.

Questions about this item

Does the single 16GB DIMM ship alone or do I need extra parts?

The box contains one 288-pin DIMM; no cables, brackets or additional modules are included.

Should I pick this 4800 CL40 1.1V module or a different speed kit?

Choose this CM2048644800DIMM when your platform specifies DDR5-4800 non-ECC unbuffered memory; all installed sticks will run at the slowest speed present.

What does the 4800 MT/s rating mean once the stick is installed?

It sets the maximum data rate; the system will operate at this speed or lower depending on the CPU memory controller and any slower modules already installed.
