SuperMicro DDR5 4800 ECC RDIMM Kit

This 512GB kit contains eight 64GB registered DDR5 modules rated at 4800MT/s with CL40 latency. It is built for SuperMicro SuperWorkstation SYS-751A-I and Super X13DAI-T platforms that require ECC registered memory. The modules operate at 1.1V and use a 2Rx4 organisation with major OEM chips.

Installing eight 288-pin RDIMMs in a server chassis

Installation follows the motherboard manual slot population rules for registered memory. The kit includes no heat spreaders, so airflow across the DIMM area must be adequate. Mixing these modules with different ranks, speeds or voltages can prevent the system from posting. Always populate identical kits per channel for stability.

Suited for memory-intensive server workloads

This capacity targets virtualisation hosts, database servers and compute nodes that need maximum registered ECC density. Builders using consumer motherboards, non-ECC platforms or boards limited to lower densities should look elsewhere. Systems that require unbuffered UDIMMs or speeds above 4800MT/s cannot use this kit.

Questions about this item

How can I confirm the 512GB kit is running at DDR5 4800 CL40 after installation?

Check the BIOS or UEFI memory information screen — it should report 4800 MT/s speed, CL40 latency, 1.10 V voltage and 512 GB total across eight 64 GB modules.

What does the kit contain and do I need any extra parts for a Supermicro SYS-751A-I?

The box holds eight 288-pin DDR5 64 GB ECC RDIMM modules (2Rx4, 1.10 V). No additional components are required for the listed Supermicro systems.

Which capacity version should I choose for a Supermicro X13DAI-T workstation?

This 512 GB (8 × 64 GB) kit matches the maximum supported capacity per processor on the X13DAI-T; select it when you need the full 512 GB per CPU.
