1.5 TB DDR5 RDIMM kit

This kit provides 1.5 TB of DDR5 server memory across twelve 128 GB registered DIMMs. It targets enterprise servers and workstations that require ECC protection and registered signalling for large-capacity configurations. The modules operate at 4800 MT/s with a CAS latency of 40 and a standard 1.10 V supply. Buyers needing non-ECC or unbuffered memory for consumer platforms should look elsewhere.

Registered ECC 288-pin modules

Each module uses a 288-pin RDIMM form factor with 4Rx4 organisation and on-die ECC for data integrity. The registered buffer reduces electrical load on the memory controller, allowing all twelve slots to be populated without signal degradation. No heat spreaders are fitted, so airflow across the DIMM rows must be sufficient for sustained server workloads. Systems that cannot supply 1.10 V or that lack RDIMM support will not accept these modules.

Verify DDR5 RDIMM platform support

Before ordering, confirm that your motherboard or server chassis supports DDR5 RDIMM memory at 4800 MT/s and can address 128 GB per slot across twelve slots. Check the qualified vendor list for 4Rx4 registered modules and ensure the BIOS revision enables the full 1.5 TB capacity. Platforms limited to UDIMM, lower densities or earlier DDR generations will not work with this kit.

Questions about this item

What does the PC5-38400 rating mean for the DDR5 interface speed?

PC5-38400 is the JEDEC designation for DDR5 4800 modules, confirming the kit operates at 4800 MT/s with CL40 latency at 1.10V

What physical slot and module dimensions are required for this 12 x 128 GB kit?

Each module is a 288-pin DDR5 RDIMM; the server board must provide 12 DDR5 RDIMM slots with matching keying and registered-buffer support

What is the correct installation sequence for a 12-module 4Rx4 registered kit?

Populate all 12 slots following the motherboard's population chart for 4Rx4 RDIMMs; the common error is mixing ranks or skipping the prescribed slot order
