8GB DDR4 2133 ECC RDIMM for servers

This 8GB DDR4 2133 registered DIMM provides error-correcting memory for compatible server platforms. The module operates at 1.20V with CL15 latency and a 1Rx4 organisation. It is built for systems that require registered ECC memory rather than unbuffered consumer modules. Buyers who need higher capacities or faster speeds should look elsewhere.

Check motherboard qualification

Verify that your motherboard appears in the validated list such as MBD-X10DAC, MBD-X10DAL-i, MBD-X10DAX or other X10 series boards. The module uses 288-pin DDR4 SDRAM and requires registered DIMM support with ECC enabled in the BIOS. Ensure free DIMM slots exist and that the platform accepts 1Rx4 registered modules at 2133 MT/s.

Registered design maintains signal integrity under

The on-board registers buffer clock, command and control signals to reduce electrical loading on the memory controller during sustained operation. ECC parity detection corrects single-bit errors that can accumulate during long-running workloads. The 1.20V operation keeps power draw stable across extended duty cycles in qualified server chassis.

Points forts

  • ECC protection prevents data errors with built-in parity check
  • Registered design stabilises signals through on-module registers
  • 8 GB capacity adds memory headroom for server workloads
  • DDR4 2133 speed delivers 17000 MB/s bandwidth at CL15
  • 2 V operation reduces power draw per module

Questions sur cet article

What comes in the box and is anything else needed to install the module?

The box contains one 8 GB 288-pin DDR4 RDIMM. No extra parts are required; the module plugs directly into a compatible server motherboard slot.

How do I decide between the listed part numbers such as CT8G4RFS4213, HMA41GR7MFR4N-TF and KVR21R15S4/8?

Those numbers are cross-references from other brands for the same 8 GB DDR4-2133 CL15 1Rx4 ECC registered specification. Choose the one that matches your vendor preference or existing stock.

What does the DDR4-2133 PC4-17000 rating mean for real-world server performance?

It indicates a maximum data rate of 2133 MT/s and a peak bandwidth of 17000 MB/s per module, with CL15 latency and 1.20 V operation, suitable for validated X10-series motherboards.
