Server DDR5 RDIMM for workstations

This 16 GB DDR5 4800 module is a JEDEC-standard registered ECC DIMM built for select servers and workstations. It runs at 1.1 V with CL40 latency and a 1Rx4 organisation across 288 pins.

Suits ECC registered platforms only

It fits systems that require registered ECC DDR5 and cannot be used in standard desktops or mixed with unbuffered or load-reduced modules. Buyers needing non-ECC consumer memory should look elsewhere.

16 GB single-module capacity

One DIMM adds 16 GB of registered ECC memory for multi-tasking and larger datasets in compatible servers. Capacity scales by populating additional slots with identical modules; a single stick cannot exceed 16 GB.

Soalan tentang produk ini

What type of server or workstation motherboard slot does this 16GB DDR5 4800 CL40 RDIMM require?

The module installs in a 288-pin DDR5 RDIMM slot on a motherboard that supports ECC registered memory at 1.1V.

Can I mix this 1Rx4 ECC registered module with unbuffered or load-reduced DIMMs already in my system?

No. The manufacturer states it cannot be mixed with unbuffered or ECC load-reduced memory; all DIMMs should match in type, capacity and speed.

How can I verify the module is running at its rated DDR5 4800 speed and CL40 latency after installation?

Check the BIOS memory information or a system utility such as CPU-Z to confirm the operating frequency shows 4800 MT/s and timings match CL40.
