Server-grade DDR5 ECC RDIMM kit

This V-color STANDARD ECC R-DIMM kit provides 64GB of DDR5 memory across four 16GB modules. It operates at 4800MHz with CL40 latency and 1.10V voltage. Registered ECC design with Hynix ICs targets server and workstation platforms requiring error correction and stability.

Registered design for multi-module scaling

The 288-pin RDIMM format uses a register to buffer address and command signals, reducing electrical load on the memory controller. This allows the four 1Rx8 modules to populate slots without overdriving the bus. ECC functionality corrects single-bit errors to maintain data integrity in critical workloads.

Upgrade from lower-capacity DDR5 RDIMM kits

Replacing smaller registered kits with this 64GB set increases total memory for virtualisation or database tasks. The jump is worthwhile when workloads exceed current capacity or when moving from non-ECC memory to gain error correction. Desktop platforms cannot use these modules.

Questions about this item

How much memory bandwidth does the DDR5 4800 speed provide?

The modules run at DDR5 4800 which equals PC5 38400 bandwidth for sustained throughput.

Will the registered DIMMs run hot or loud without a heat spreader in continuous server use?

Operating at 1.10 V with no heat spreader keeps thermals low; the registered buffer adds negligible heat so standard chassis airflow is sufficient.

Does my motherboard need to support ECC registered DIMMs for this 4 x 16 GB kit to work?

Yes, the kit requires a server or workstation board with 288 pin DDR5 RDIMM slots and ECC registered support.
