ASUS K14PA-U12 DDR5 RDIMM kit

This 192GB kit contains twelve 16GB DDR5 4800 ECC registered DIMMs built for the ASUS K14PA-U12 motherboard. It targets administrators scaling memory on 128-core AMD EPYC 9004 platforms.

Registered ECC limits at DDR5 4800

Registered DIMMs add a buffer that stabilises heavy loads but introduces one cycle of latency versus unbuffered modules. The JEDEC DDR5 4800 standard caps this kit at 4800 MT/s and CL40 timings.

Verify twelve-slot population rules

Confirm the K14PA-U12 supports twelve 1Rx8 modules per processor and that your BIOS revision enables full-speed operation with all slots filled. Check maximum capacity per channel before ordering.

Questions about this item

Should I choose the 12-module 192GB kit or a smaller capacity for my ASUS K14PA-U12?

The 12-module kit provides 192GB total using 12x16GB RDIMMs, matching the 128-core AMD EPYC 9004 platform's memory channel count for balanced bandwidth across all channels.

What does the 4800 MT/s speed mean once installed in the server?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V, delivering the rated transfer rate when the motherboard firmware configures the memory controllers for that speed.

How does the DDR5 288-pin RDIMM interface limit performance in this system?

The registered DDR5 RDIMM interface operates at 4800 MT/s with ECC enabled, and the 1Rx8 organisation on each 16GB module determines the maximum rank density the memory controller can address per channel.
