256GB DDR4 ECC RDIMM kit

This 256GB kit contains sixteen 16GB DDR4 3200 registered DIMMs with ECC and a CL22 latency. It is built for the ASUS KRPA-U16 motherboard using the AMD EPYC 7002 platform in LGA 4094 servers. The modules run at 1.2V and use a 2Rx8 organisation.

Registered DDR4 3200 interface limits

Registered DIMMs add a clock cycle of buffering that stabilises heavy loads but prevents use in consumer boards that expect unbuffered memory. The DDR4 3200 standard caps transfer rates at PC4-25600, so faster modules will downclock to this speed. ECC function requires a compatible chipset and BIOS.

Sixteen-module population requirement

The kit delivers exactly sixteen 16GB sticks, matching the full slot count of the target motherboard. Builders needing fewer than sixteen modules or a different capacity per DIMM cannot use this kit as supplied.

Questions about this item

Should I choose the 16x16GB kit or a smaller capacity for my ASUS KRPA-U16?

The 256GB kit provides 16 modules of 16GB each, filling all 16 DIMM slots on the ASUS KRPA-U16 for maximum supported capacity with dual-rank 2Rx8 modules.

What does the 3200 speed rating mean when installed in an EPYC 7002 system?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V, delivering the rated transfer rate when the EPYC 7002 memory controller is configured for that speed.

How does the 288-pin RDIMM interface limit performance on this motherboard?

The 288-pin DDR4 RDIMM interface connects to the EPYC 7002 LGA 4094 memory controller, capping transfer rates at the DDR4 3200 specification with registered buffering for signal integrity.
