768GB DDR5 RDIMM kit for Supermicro H13DSG-O-CPU

This NEMIX RAM kit delivers 768GB across twelve 64GB DDR5-4800 registered ECC modules. Each stick runs at 1.1V with CL40 latency and a 2Rx4 organisation. The 288-pin RDIMM form factor matches the Supermicro H13DSG-O-CPU motherboard exactly.

Suited for servers needing maximum registered ECC

Ideal for administrators populating every slot on a compatible Supermicro board with validated DDR5 RDIMMs. Not for systems that require unbuffered UDIMMs, SODIMMs, or a different DDR generation. Builders without the motherboard manual's population rules should verify before ordering.

Twelve-module kit enables full-channel population

The 12 x 64GB configuration lets you fill all supported channels at once, ensuring the memory controller sees the full 768GB at rated speed. No extra software or accessories are included; the modules themselves provide the registered buffer and ECC correction that keep data integrity intact under sustained load.

Questions about this item

My Supermicro H13DSG-O-CPU board has 12 DDR5 slots — will this 12-module kit fill every slot?

Yes, the kit provides exactly 12 modules at 64 GB each, matching the board's 12-slot layout so every DIMM socket is populated.

If I keep a few of my existing DDR5 4800 RDIMMs, can I mix them with these 2Rx4 modules?

Mixing ranks can change the memory controller's addressing; the board manual specifies the approved population order for 2Rx4 modules and should be followed to avoid reduced speeds or unrecognised capacity.

After installing all 12 sticks, how do I confirm the system sees the full 768 GB at 4800 MHz with ECC active?

Enter the BIOS or run a hardware inventory tool — it should report 768 GB total, DDR5-4800 operating speed, CL40 timings, and ECC enabled for each channel.
