Server memory kit

This NEMIX RAM kit supplies 64 GB of DDR4 ECC registered memory across eight 8 GB modules. It targets administrators expanding ASUS KRPA-U16 platforms built around AMD EPYC 7002 processors. The registered design and error correction suit workloads that demand data integrity over raw latency.

Registered DDR4 3200 modules

Each 288-pin RDIMM runs at 3200 MT/s with CL22 timing at 1.20 V and uses a 1Rx8 organisation. Major OEM DRAM from Samsung, Micron or Hynix is stress-tested before shipment. The lack of heat spreaders keeps module height low for dense server chassis, while registration buffers address and command signals for electrical stability.

Upgrade path for EPYC 7002 systems

The kit replaces smaller or slower DDR4 populations on the KRPA-U16 motherboard, filling all eight channels when maximum capacity is required. It is not suited for unbuffered consumer boards, laptops or any platform that cannot accept registered ECC DDR4. Builders needing higher frequencies or non-ECC operation should look elsewhere.

Questions about this item

What DDR4 standard does this PC4-25600 kit run at, and what speed does that cap at?

It operates as DDR4 3200 PC4-25600, so the data rate is capped at 3200 MT/s in practice.

What physical slot and module count are needed to install this 64GB kit?

Eight 288-pin DDR4 RDIMM slots are required, one for each 8GB module in the kit.

What installation step is often missed when seating these registered ECC DIMMs?

Align the notch, press firmly until both side clips click, then verify the motherboard detects all 64GB at 3200 MT/s in BIOS.
