Server DDR4 kit for ECC workloads

This 8 GB kit contains two 4 GB registered DIMMs built for DDR4 servers and workstations that require error-correcting memory. Each module is a single-rank 1Rx8 design running at 2133 MHz with CL15 latency. The kit is not compatible with desktop or laptop platforms.

Sustained operation with registered buffering

The registered buffer reduces electrical load on the memory controller, helping stability during continuous multi-threaded workloads. ECC circuitry detects and corrects single-bit errors without halting the system. Standard 1.2 V operation keeps power draw predictable under load.

288-pin DDR4 ECC RDIMM form factor

Only systems that accept DDR4 288-pin registered ECC modules can use this kit. Buyers whose motherboards require unbuffered UDIMMs or a different DDR generation cannot install these modules.

Questions about this item

Will the 1.2 V registered ECC modules add noticeable heat or fan noise when the server runs continuously?

The kit operates at the standard DDR4 voltage of 1.20 V and has no heat spreader, so thermal output stays within normal DDR4 limits for registered DIMMs.

My motherboard has 288-pin DDR4 slots — is anything else required for these RDIMMs to work?

You need a server or workstation platform that explicitly supports DDR4 ECC registered memory; desktop and laptop boards will not accept these modules.

Can I mix this 1Rx8 CL15 kit with existing single-rank DDR4 ECC RDIMMs of a different capacity?

Mixing ranks and capacities is possible only if the system manual approves the specific population rules for your server or workstation.
