  • 288-pin RDIMM form factor fits the Supermicro H14DSG-O-CPU memory slots precisely

Server-grade DDR5 ECC RDIMM kit for Supermicro

This 768GB kit contains six 128GB DDR5-5600 registered ECC modules built to the exact rank, voltage and timing the Supermicro H14DSG-O-CPU memory controller expects. It targets administrators who need maximum supported capacity in every slot for virtualization, database or compute workloads.

DDR5-5600 registered interface limits

The DDR5-5600 (PC5-44800) standard delivers 5600 MT/s at 1.1V with CL46 latency, but full-speed operation requires the motherboard to support 2Rx4 registered DIMMs in a six-module population. If the board's qualified-vendor list restricts maximum capacity per slot or total channels, the kit will down-clock or fail to post.

768GB total capacity across six registered DIMMs

The single specification that decides fitment is the 768GB (6×128GB) 2Rx4 registered ECC configuration; the Supermicro H14DSG-O-CPU must explicitly support this exact population and capacity in its memory-reference guide, otherwise the system will not recognise the full amount or will not boot.

Questions about this item

Should I choose the 768GB 6×128GB kit or a different capacity for the Supermicro H14DSG-O-CPU?

The 768GB kit uses six 128GB DDR5-5600 RDIMMs at 1.1V with CL46 timing. It matches the board's required 2Rx4 rank, registered ECC design and 288-pin form factor so the memory controller recognises full capacity at rated speed.

What does the DDR5-5600 CL46 rating deliver once installed in the server?

The modules run at 5600 MT/s with a CAS latency of 46 cycles at 1.1V. Registered buffering offloads the memory controller, allowing all six slots to operate fully populated while ECC corrects single-bit errors on the fly to prevent silent data corruption.

How does the PC5-44800 DDR5 interface limit real-world throughput?

The PC5-44800 designation means a peak transfer rate of 44800 MB/s per module. With six 2Rx4 RDIMMs the memory controller can sustain near-peak bandwidth across all channels, capped by the DDR5-5600 clock and the board's population rules.
