64GB DDR4 3200 ECC RDIMM kit

This 64GB kit contains four 16GB DDR4 3200 modules built to PC4-25600 spec. Each stick is a 288-pin registered DIMM with ECC and a CL22 latency running at 1.20V. The memory uses major OEM chips from Samsung Micron or Hynix and is validated for the ASUS KRPA-U16 motherboard with AMD EPYC 7002 processors in LGA 4094 servers.

Suited for EPYC 7002 server builds

This kit targets administrators upgrading or populating the ASUS KRPA-U16 platform where registered ECC memory is mandatory. It will not work in systems that require unbuffered non-ECC UDIMMs or in boards that do not support DDR4 3200 registered modules. Buyers needing higher densities per slot or lower latency timings should look elsewhere.

Four modules give 64GB total capacity

The 4x16GB arrangement fills four DIMM slots and delivers 64GB of registered ECC memory for multi-threaded server workloads. Headroom ends when the platform's maximum supported memory per channel or total socket limit is reached. Further expansion requires higher-density RDIMMs or additional memory channels not addressed by this kit.

Questions about this item

Will my ASUS KRPA-U16 motherboard with an AMD EPYC 7002 processor accept these 288-pin DDR4 RDIMM modules?

Yes, this kit is built for the ASUS KRPA-U16 platform with AMD EPYC 7002 CPUs and uses the 288-pin DDR4 RDIMM form factor required by that board.

Can I mix these CL22 registered ECC sticks with older unbuffered non-ECC DDR4 DIMMs I already own?

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

How do I confirm the kit is running at the rated 3200 MT/s with CL22 timings after installation?

Enter the system BIOS or use a tool like CPU-Z to verify the memory operates at DDR4 3200 (PC4-25600) with a CAS latency of 22.
