128 GB DDR5 ECC R-DIMM kit for servers

This V-color kit provides 128 GB of DDR5 memory in four 32 GB registered DIMMs. Each module runs at 4800 MT/s with CL40-39-39-77 timings at 1.10 V and uses SK Hynix ICs in a 1Rx4 configuration. The registered design and on-die ECC target data integrity in multi-socket platforms.

Workstations and servers needing registered ECC

The 288-pin R-DIMMs fit server and workstation motherboards that require registered DDR5 with error correction. Desktop boards that accept only unbuffered non-ECC UDIMMs cannot use these modules. Buyers who need unbuffered ECC or consumer UDIMMs should look at a different product line.

Registered DDR5 with on-die ECC at 4800 MT/s

The combination of registered buffering and ECC at the standard DDR5-4800 data rate determines whether the kit matches the motherboard's qualified vendor list. Verify that the platform supports 1Rx4 registered modules at this speed and voltage before ordering.

Questions about this item

What is the CAS latency and timing that limits sustained throughput?

The kit runs at CL40 with 40-39-39-77 timings, so the CAS latency of 40 cycles is the first limit you hit under sustained load.

How much heat and power should I expect when the modules run all day?

Operating at 1.10 V without a heat spreader, the DDR5 ECC R-DIMMs draw minimal power and run cool enough for continuous server workloads.

Which motherboard slot and platform do I already need for these 288-pin modules?

You need a server or workstation motherboard with DDR5 RDIMM slots; desktop boards will not accept this memory.
