Server Memory Kit

This NEMIX RAM kit delivers 256GB of DDR5 memory across four 64GB modules running at 6400MHz with CL52 latency. The registered ECC RDIMM design operates at 1.10V and uses a 2Rx4 rank configuration. It is built for the ASRock Rack GNRAPD12DNO motherboard where full-capacity population and error correction are required.

Suited for registered ECC platforms

The 288-pin registered form factor and ECC function suit servers that demand data integrity and stable operation with all slots filled. Systems needing unbuffered UDIMMs, non-ECC memory, SODIMM modules, or a different DDR generation will not accept this kit.

Build integration

Four modules populate the board's DDR5 RDIMM slots at the rated 6400MHz speed and 1.10V voltage. The registered architecture reduces electrical load on the memory controller when fully populated, while ECC corrects single-bit errors in flight. Verify the motherboard manual for approved population order and maximum supported capacity before installation.

Domande su questo articolo

Must my ASRock Rack GNRAPD12DNO motherboard already support DDR5 6400 PC5-51200 registered ECC RDIMMs for this 256GB kit to work?

Yes — the board must accept 288-pin DDR5 RDIMMs at 6400 MT/s with registered ECC; this kit is spec-matched to that exact requirement.

Can I keep any existing DDR5 6400 registered ECC RDIMMs installed while adding these four 64GB 2Rx4 modules?

Only if the motherboard manual approves mixing 2Rx4 ranks in the same channel population; otherwise the board may not train at full 6400 speed.

How do I confirm the system sees all 256GB at DDR5 6400 CL52 1.1V after installation?

Enter BIOS or run a tool like dmidecode — each slot should show 64GB, 6400 MT/s, CL52, 1.1 V, registered ECC, 2Rx4 organisation.
