  • 288-pin RDIMM form factor fits the ASRock Rack GENOA2D16NQM3-2Q motherboard exactly

Exact-Match Server Upgrade

This 192GB kit contains two 96GB DDR5 RDIMMs rated at 6400MHz with CL52 latency and 1.1V operation. The modules use a 2Rx4 registered ECC design that matches the memory controller requirements of the ASRock Rack GENOA2D16NQM3-2Q motherboard.

Suited For Specific Platforms

The kit is built for administrators upgrading that exact ASRock Rack board where registered ECC RDIMMs are required. Builders needing unbuffered UDIMMs, SODIMM form factors, or non-ECC memory for workstation or consumer platforms should look elsewhere.

Sustained Enterprise Operation

Registered buffering reduces electrical load on the memory controller so all slots remain stable at full population and rated speed. On-die ECC corrects single-bit errors continuously, preventing silent data corruption during long-running workloads.

Questions about this item

Which motherboard must I already have for this NEMIX RAM kit to be a verified fit?

The kit is validated for the ASRock Rack GENOA2D16NQM3-2Q motherboard that requires DDR5 6400MHz PC5-51200 registered DIMMs.

Will these 2Rx4 registered ECC modules run alongside any existing RDIMMs I keep in the server?

Mixing ranks or registered ECC DIMMs can break the memory controller's population rules; consult the motherboard manual for approved slot order before adding them.

How do I confirm the 192GB kit is running at its rated 6400MHz CL52 after installation?

Check the BIOS memory information or run a hardware utility such as dmidecode to verify speed shows 6400 MT/s and latency CL52.
