128GB DDR4 3200 ECC RDIMM kit

This 128GB kit contains four 32GB DDR4 3200 registered DIMMs with ECC and a 2Rx8 organisation. It is built for servers and workstations that require registered memory and cannot accept standard unbuffered modules. The quad-channel kit delivers 128GB total capacity for memory-intensive workloads.

Registered DDR4 3200 interface limits

The modules run at DDR4 3200 (PC4-25600) with CL22 latency at 1.20V. Registered DIMMs add a clock cycle of buffering, so they only work in platforms designed for registered memory; they will not function in desktop or laptop systems that expect unbuffered DIMMs. ECC provides error detection and correction for data integrity.

Upgrade from smaller registered kits

This kit replaces lower-capacity registered DDR4 sets when a server or workstation needs more memory for virtualisation, databases or large datasets. The jump is worthwhile when the platform supports quad-channel population and the workload exceeds the current memory ceiling. It does not fit systems that require unbuffered or non-ECC memory.

Questions about this item

Should I choose the 4×32 GB kit or a smaller capacity for my server?

The 128 GB quad-channel kit uses four 32 GB modules; select it when your workload needs the full capacity and your platform supports four DIMM slots in quad-channel mode.

What does the DDR4 3200 speed mean once the modules are installed?

The modules run at 3200 MT/s with CL22 latency at 1.20 V, delivering PC4-25600 bandwidth when the memory controller is configured for that data rate.

Is the 288-pin RDIMM interface compatible with standard DDR4 server boards?

Yes, the 288-pin registered DIMM with ECC and 2Rx8 organisation fits DDR4 server and workstation platforms that require registered memory; desktop and laptop systems are not supported.
