1 TB DDR5 ECC RDIMM kit

This kit provides 1 TB of DDR5 server memory across eight 128 GB registered DIMMs. It targets enterprise servers and workstations that require error-correcting code for data integrity. The modules operate at 1.1 V and use 4Rx4 organisation. Buyers needing non-ECC or unbuffered memory should look elsewhere.

DDR5 4800 registered interface

The DDR5 4800 standard sets the electrical and timing envelope for these modules at CL40 latency. Registered buffering adds a clock cycle to command paths, so the memory controller must support registered DIMMs. ECC capability depends on a platform that can enable and use the extra parity bits. Systems limited to unbuffered or lower-speed DDR5 cannot use this kit.

Platform verification before ordering

Confirm that your motherboard or server chassis lists 288-pin DDR5 RDIMM support with 4Rx4 population rules. Check the qualified vendor list for 128 GB per slot density and 1 TB total capacity. Verify that the BIOS or firmware revision enables ECC at 4800 MT/s. Without these confirmations the modules may not post or may run at reduced speeds.

Questions about this item

How many 128GB modules make up the 1TB kit?

The kit contains eight 128GB modules, giving a total of 1TB capacity.

What does the DDR5 4800 speed rating mean for actual throughput?

The PC5-38400 designation indicates a peak transfer rate of 38,400 MB/s per module.

Does the 288-pin RDIMM form factor limit which servers can use this memory?

It fits any server board with DDR5 RDIMM slots; the registered design and ECC require chipset support for those features.
