Capacity and Compatibility

This 256GB kit contains eight 32GB DDR4 3200 RDIMM modules built for the ASUS KRPA-U16 motherboard. It targets administrators expanding EPYC 7002 servers that require registered ECC memory at 1.20V.

Build and Connectors

Each module uses a 288-pin DDR4 RDIMM form factor with 2Rx8 organisation and CL22 latency. The registered design adds a buffer for signal integrity in high-density configurations, while the lack of heat spreaders keeps the profile low for dense server chassis.

Upgrade Path

The kit replaces lower-capacity DDR4 RDIMM sets or fills empty slots on the KRPA-U16 platform. The jump is worth it when workloads exceed the current memory ceiling and the board supports the full 256GB population.

Questions about this item

What bandwidth does the DDR4 3200 PC4-25600 interface deliver in practice?

The DDR4 3200 PC4-25600 interface delivers up to 25600 MB/s theoretical bandwidth; actual throughput depends on the ASUS KRPA-U16 platform and EPYC 7002 memory controller.

What physical slot and module dimensions are required for these 288-pin RDIMMs?

Each module uses a standard 288-pin DDR4 RDIMM form factor without heat spreaders; the ASUS KRPA-U16 motherboard must provide registered DIMM slots supporting 2Rx8 organisation.

How are the eight 32 GB modules installed on the ASUS KRPA-U16, and which step is commonly missed?

Populate all eight slots per the motherboard's population rules for EPYC 7002; the step often missed is verifying the BIOS recognises all 256 GB at 3200 MT/s with CL22 timings after seating.
