Exact-match DDR5 server upgrade

This 32 GB DDR5 6400 RDIMM carries a 1Rx4 registered ECC layout at 1.10 V and CL52, matching the memory controller expectations of the ASRock Rack GNRAPD12DNO motherboard. The 288-pin form factor is the only module type that fits the board's DDR5 slots.

Builders needing registered ECC stability

The registered architecture offloads the memory controller so every slot can run fully populated at rated speed while ECC corrects single-bit errors on the fly. Buyers who want unbuffered UDIMMs, non-ECC modules or SODIMM form factors will not be able to use this kit.

Fits DDR5 RDIMM slots on the target board

The module slots directly into the 288-pin DDR5 RDIMM sockets on the ASRock Rack GNRAPD12DNO without adapters. Its 1.10 V operation leaves headroom within the platform's power budget and the single-rank design simplifies population rules for full-capacity configurations.

Questions about this item

What motherboard and DDR5 generation must I already have for this 288-pin RDIMM to work?

You need an ASRock Rack GNRAPD12DNO motherboard that supports DDR5 6400 PC5-51200 Registered ECC memory. The board must accept 288-pin RDIMMs at 1.1V with CL52 timing.

Can I mix this 1Rx4 Registered ECC module with older UDIMM or non-ECC DDR5 sticks?

No. Registered RDIMMs cannot be mixed with unbuffered UDIMMs, and ECC modules require a platform that enables error correction. Population rules in the motherboard manual dictate supported combinations.

How do I verify the module runs at 6400MHz CL52 1.1V after installation?

Enter the BIOS or use a hardware-info utility to confirm the DIMM reports DDR5-6400, PC5-51200, CL52 latency, 1.1V voltage, and Registered ECC status with 32GB capacity.
