512GB DDR4 ECC LRDIMM Kit

This 512GB kit contains eight 64GB DDR4 3200 ECC LRDIMM modules built for the ASUS KRPA-U16 motherboard with AMD EPYC 7002 processors. Load-reduced design lowers electrical load on the memory controller at high density. CL22 latency and 1.2V operation match the platform specification. Modules use major OEM Samsung, Micron or Hynix chips.

Suited for maximum-capacity EPYC 7002 servers.

Builders populating every DIMM slot on a compatible ASUS KRPA-U16 board for virtualization, database or HPC workloads will use the full 512GB. Systems that do not support LRDIMM, DDR4 3200 or the EPYC 7002 memory controller cannot use this kit. Buyers needing standard RDIMM or non-ECC memory must choose a different product.

4Rx4 rank configuration decides compatibility

Each module is organised as 4Rx4, a requirement for the KRPA-U16 memory topology at this density. The motherboard and CPU memory controller must explicitly support 4Rx4 LRDIMM population rules. Verify the platform qualified-vendor list before purchase; an incompatible rank structure will prevent boot or reduce usable capacity.

Questions about this item

What does the 3200 MHz speed mean when the modules are installed in the ASUS KRPA-U16?

The memory runs at DDR4 3200 with CL22 timing, delivering the rated PC4-25600 data rate once the EPYC 7002 processor initialises the LRDIMM modules.

How does the 288-pin LRDIMM interface affect bandwidth on this platform?

The 288-pin DDR4 LRDIMM load-reduced design presents a single electrical load per rank, allowing all eight 64 GB modules to operate at the full 3200 MHz without signal degradation.

What physical clearance does the 8-module kit need inside the EEB chassis?

Eight 288-pin LRDIMMs occupy every DIMM slot on the ASUS KRPA-U16; each module is standard height with no heat spreader, so only the motherboard's slot spacing and CPU-cooler clearance apply.
