128 GB DDR5 ECC RDIMM kit

This 128 GB kit contains four 32 GB DDR5 RDIMM modules rated at 4800 MT/s with CL40 latency and 1.10 V operation. It targets servers and workstations that require registered ECC memory for data integrity and high capacity.

Suits ECC registered platforms only

The modules are registered ECC RDIMMs, so they will not function in consumer desktop boards or laptops that accept only unbuffered non-ECC DIMMs. Buyers who need standard DDR5 UDIMMs for a regular PC should look at a different product line.

Fills four 288-pin DDR5 slots

Each module uses the 288-pin DDR5 RDIMM form factor and draws 1.10 V, leaving other DIMM slots free for further expansion if the motherboard supports more than four channels. No heat spreader is fitted, so airflow across the PCB must be provided by the chassis.

Questions about this item

Will my motherboard need DDR5 slots to accept these 288-pin RDIMMs?

Yes, these are DDR5 4800 modules with a 288-pin RDIMM form factor, so the board must provide DDR5 RDIMM slots.

Can I mix these 2Rx4 registered modules with unbuffered DIMMs already in the system?

No, registered ECC RDIMMs cannot be mixed with unbuffered memory; the motherboard requires all slots to use registered modules.

How do I confirm the kit is running at the rated 4800 MT/s and CL40 after installation?

Check the BIOS memory information or a tool such as CPU-Z; it should report DDR5-4800, CAS 40, 1.10 V and 128 GB total across the four 32 GB modules.
