128GB DDR4 2933 ECC RDIMM Kit

This 128GB kit contains four 32GB DDR4 2933 MHz registered DIMMs with ECC. It is built for servers and workstations that require registered memory and can use dual-rank x4 modules. The kit runs at 1.2V with a CAS latency of 21.

Compatibility Check Before Ordering

Your system must support DDR4 registered ECC RDIMMs in a 288-pin DIMM form factor. Desktop and laptop computers cannot use these modules. Confirm that your motherboard or server manual lists PC4-23400 2Rx4 registered memory and provides quad-channel population rules.

Upgrading from Smaller Registered Kits

The kit replaces smaller-capacity DDR4 registered ECC kits when your workload demands more memory bandwidth and capacity. The jump is worth it when your current configuration hits memory limits during virtualization, database or compute tasks and your platform can populate four slots in quad-channel mode.

Questions about this item

What is included in the 128GB kit and do I need anything else to install it?

The kit contains four 32GB DDR4 2933 ECC Registered DIMM modules. No extra parts are required if your server or workstation has four free 288-pin DDR4 RDIMM slots.

Should I choose this 2Rx4 quad-channel kit or look for a different rank or channel configuration?

This 2Rx4 quad-channel kit suits systems that support dual-rank x4 registered memory and can populate four channels. Match the rank and channel count to your platform's memory guide.

What does the 2933 MHz rating mean for real-world server performance?

The modules run at DDR4 2933 (PC4-23400) with CL21 latency at 1.2V, delivering the rated throughput when the CPU memory controller and BIOS are configured for that speed.
