128GB DDR4 ECC RDIMM Kit

This 128GB kit contains four 32GB DDR4 3200 registered DIMMs with ECC and a CL22 latency. It is built for the ASUS KRPA-U16 motherboard running AMD EPYC 7002 processors in the LGA 4094 socket. The modules operate at 1.2V using a 2Rx8 organisation and carry no heat spreaders.

Installation Notes

The 288-pin RDIMMs seat in standard DDR4 server slots and require no tools beyond normal anti-static precautions. Because they are registered ECC modules, the system BIOS must support registered memory; consumer boards that accept only unbuffered DIMMs will not post. Mixing these sticks with different ranks, voltages or speeds can prevent the server from completing memory training.

Who Should Buy

This kit suits administrators upgrading or populating the ASUS KRPA-U16 platform where 128GB of validated ECC capacity is required. Buyers needing higher densities, faster speeds or unbuffered DIMMs for workstation or desktop platforms should look at something else.

Questions about this item

How do I verify the 128GB kit is running at 3200MHz with CL22 after installation?

Enter the BIOS on the ASUS KRPA-U16 and confirm the memory frequency shows 3200MHz, CAS latency reads CL22, voltage is 1.20V, and all four 32GB modules are detected as 2Rx8 registered ECC DIMMs.

What ships in the box and do I need extra parts for the ASUS KRPA-U16?

The box contains four 32GB DDR4 3200MHz CL22 1.2V 288-pin ECC RDIMM modules (part MR25600-328K4). No additional components are required for the compatible ASUS EPYC 7002 LGA 4094 server motherboard.

Which capacity version should I choose for the ASUS KRPA-U16?

This kit is a single 128GB (4x32GB) configuration validated for the ASUS KRPA-U16 with AMD EPYC 7002 processors. Select this exact part number when you need the full 128GB registered ECC capacity.
