Server-grade DDR5 upgrade

This NEMIX RAM kit delivers 576 GB across twelve 48 GB RDIMMs built for the Supermicro H14DSG-O-CPU motherboard. Each module runs at DDR5 6400 with CL52 latency at 1.1 V using 2Rx8 registered ECC chips. The exact rank, voltage and timing match the board's memory controller so the full capacity is recognised and operates at its rated speed.

Registered ECC architecture

Registered buffering offloads the memory controller allowing every slot to be fully populated without signal degradation. ECC corrects single-bit errors on the fly preventing silent data corruption and unplanned reboots. The 288-pin RDIMM form factor is mandatory for this platform; UDIMM or SODIMM modules will not fit or function. System manuals must be consulted for approved population order and maximum supported capacity per channel.

Capacity and headroom

Twelve 48 GB modules provide 576 GB total, suited to virtualisation hosts, in-memory databases and large-scale simulation workloads. Headroom exists until the motherboard's per-channel or per-socket limits are reached; exceeding those limits will prevent boot or reduce operating speed. Workloads that demand more memory than the platform supports will require a different server configuration.

Questions about this item

Should I buy the 576GB kit or a smaller capacity for my Supermicro H14DSG-O-CPU?

The 576GB kit provides 12 modules of 48GB each. Choose it if your workload needs the maximum supported capacity and you can populate all 12 slots following the motherboard's population rules.

What does the DDR5 6400 CL52 rating deliver inside the H14DSG-O-CPU?

The modules run at 6400 MT/s with a CAS latency of 52 cycles at 1.1V. Registered ECC buffering lets all 12 slots operate at this rated speed without downclocking when fully populated.

Does the 288-pin RDIMM interface limit how many modules I can install?

The 288-pin RDIMM form factor is required by the H14DSG-O-CPU. The registered design allows all 12 slots to be filled at full 48GB per module, but you must follow the board's specific population order.
