  • Validated across a wide range of server motherboards

8GB DDR4 2133 ECC RDIMM for servers

This 8GB DDR4 2133 ECC RDIMM is built for servers and workstations that require registered memory with error correction. The module runs at 2133 MT/s with CL15 latency at 1.20V. A single 1Rx4 rank uses 288-pin DDR4 packaging.

Upgrade from non-ECC or slower DDR4

Replacing non-ECC UDIMMs or lower-speed DDR4 with this registered ECC module adds data-integrity protection and signal buffering for multi-DIMM configurations. The jump is worth it when the platform validates M393A1G40DB0-CPB and the workload cannot tolerate silent data corruption.

Limited to DDR4 2133 registered channels

The DDR4 2133 interface caps bandwidth at the PC4-17000 rate and requires a memory controller that supports registered DIMMs. Systems that only accept unbuffered memory or that lock speeds below 2133 MT/s cannot use this module at its rated specification.

Points forts

  • 8GB capacity expands server memory headroom
  • DDR4 2133 speed delivers reliable data throughput
  • ECC registered design detects and corrects memory errors
  • CL15 latency at 1.2V balances responsiveness with efficiency
  • Validated across a wide range of server motherboards

Questions sur cet article

Will the 30 mm module height fit inside my 1U server chassis?

The module measures 30 mm tall, which is the standard height for 288-pin DDR4 RDIMMs and fits typical 1U server memory slots.

Which slot orientation and alignment step avoids a bent pin when installing this 288-pin DDR4 RDIMM?

Align the off-centre notch on the module with the key in the slot, press straight down until both side clips click, and do not rock the module.

How do I verify that ECC correction is active after installing this 1Rx4 registered module?

Enable ECC in the BIOS, then check the operating-system memory report or IPMI logs for corrected-error counters to confirm operation.
