32GB DDR4 ECC RDIMM kit

This NEMIX RAM kit provides 32GB of DDR4 2400 memory in two 16GB registered DIMMs. It is built for servers and workstations that require error-correcting code and registered signal integrity. The modules operate at 1.2V with a CAS latency of CL17 and use a 288-pin 2Rx8 layout. They are validated for the ASRock Rack ROMED8-2T motherboard supporting AMD EPYC processors.

For registered ECC server upgrades

This memory suits administrators expanding capacity in compatible ASRock Rack platforms that demand registered ECC DDR4 RDIMMs. It will not work in systems that only accept unbuffered non-ECC UDIMMs or require a different pin count, voltage, or speed grade. Builders needing consumer desktop memory or laptop SO-DIMMs should look elsewhere.

2400MHz CL17 registered ECC specification

The decisive specification is the DDR4 2400MHz CL17 registered ECC RDIMM standard. Only motherboards qualified for this exact speed, latency, voltage, and registered ECC protocol will support the kit. Verify the platform memory QVL matches PC4-19200 2Rx8 1.2V 288-pin requirements before purchase.

Questions about this item

Should I choose the 2x16GB kit or a single 32GB module for my ASRock Rack ROMED8-2T?

The 2x16GB kit populates two channels for higher bandwidth on the EPYC platform, while a single 32GB module would run in single-channel mode.

What does the 2400MHz speed mean once installed in the server?

The modules run at DDR4 2400 with CL17 latency at 1.20V, delivering PC4-19200 throughput when the motherboard sets the correct JEDEC profile.

Is the 288-pin RDIMM interface compatible with standard DDR4 UDIMM slots?

No, the 288-pin RDIMM is a registered ECC form factor that requires a server or workstation motherboard with RDIMM support; it will not work in consumer UDIMM slots.
