ASUS EPYC 7002 server memory kit

This 128 GB kit contains two 64 GB DDR4 LRDIMM modules validated for the ASUS KRPA-U16 motherboard with AMD EPYC 7002 processors. It targets administrators upgrading memory capacity in compatible enterprise servers.

Load-reduced ECC at 1.2 V

The modules run at DDR4 3200 with CL22 latency and 1.20 V, using load-reduced buffering to lower electrical load on the memory controller. ECC protection corrects single-bit errors during sustained workloads.

4Rx4 organisation for high density

Each module uses a 4Rx4 rank structure to deliver 64 GB per DIMM within the 288-pin form factor. Systems requiring lower-rank configurations or non-ECC memory cannot use this kit.

Questions about this item

How do I install the 288-pin LRDIMM modules in the ASUS KRPA-U16 motherboard, and what step is often missed?

Align the notch on each 288-pin LRDIMM with the slot key, press down firmly until both retention clips click, then verify in BIOS that all 128GB are detected at 3200 MT/s; the step often missed is seating both clips fully on each module.

What maintenance or replacement will the 4Rx4 ECC LRDIMM kit need over time?

The modules have no heat spreader and no moving parts, so no routine maintenance is required; replacement is only necessary if a module fails, which is covered by the manufacturer lifetime replacement warranty.

What limit appears first when the 1.2V DDR4 3200 CL22 kit runs sustained workloads on the EPYC 7002 platform?

The CAS latency of CL22 at 3200 MT/s sets the timing boundary, and the 1.2V operating voltage limits further frequency scaling; thermal throttling is unlikely without a heat spreader under normal server airflow.
