Exact-match server upgrade

This 128 GB DDR5-6400 module is built for the ASRock Rack GNRAPD12DNO motherboard. It uses a 288-pin RDIMM form factor with registered ECC architecture and a 2Rx4 rank layout. The 1.1 V operating voltage and CL52 timing match the board's memory controller requirements exactly.

Replaces non-ECC or slower DDR5

The jump is worth it when your workload demands full-slot population without signal degradation and on-the-fly single-bit error correction. Unbuffered DIMMs or lower-speed modules cannot deliver the same stability at maximum capacity across every channel.

Fits registered-DIMM platforms only

The board must support registered ECC RDIMMs and the specific population order listed in its manual. No heat spreader is included, so airflow across the modules must be provided by the chassis. This kit frees you from mixing ranks or voltages that cause boot failures or reduced throughput.

商品問答

Will the 288-pin RDIMM fit the ASRock Rack GNRAPD12DNO motherboard DIMM slots?

Yes, the 288-pin Registered RDIMM form factor matches the DDR5 slots on the ASRock Rack GNRAPD12DNO motherboard; it is not a UDIMM or SODIMM.

What is the correct population order when installing this 2Rx4 Registered ECC module?

Follow the motherboard manual for the approved DIMM population sequence; registered modules must be installed in the specified slot order for full capacity recognition.

Does the lack of a heat spreader affect long-term reliability of this 128GB DDR5 module?

The module operates at the standard 1.1V DDR5 voltage without a heat spreader; adequate chassis airflow is recommended for sustained server workloads.
