4GB DDR4 2133 ECC UDIMM for Servers

This 4 GB DDR4 2133 module adds error-correcting memory to compatible servers and workstations. It runs at 1.20 V with a CL15 latency and uses a 1Rx8 unbuffered layout. The 288-pin DIMM fits standard DDR4 slots in systems that support ECC unbuffered memory.

DDR4 2133 speed and ECC limits

DDR4 2133 sets the maximum data rate at 2133 MT/s, so the module cannot run faster even if the platform supports higher speeds. ECC unbuffered memory requires a chipset and CPU that both enable error correction without registered buffering; consumer platforms typically disable this feature. The single-rank 1Rx8 organisation caps density per module at 4 GB.

Replaces Kingston KVR21E15S8/4

This A-Tech module is a direct replacement for the Kingston KVR21E15S8/4 part number. The upgrade is worthwhile when a system has empty DDR4 ECC UDIMM slots and the workload benefits from extra capacity or from replacing a failed stick. It is not suited for platforms that require registered or load-reduced DIMMs, nor for boards that only accept non-ECC memory.

أسئلة حول هذا المنتج

Should I pick the 4GB 2133MHz CL15 module or a higher-capacity stick?

Choose the 4GB module when your server has limited DIMM slots and you only need a small capacity increase; add another identical 4GB stick later if the board supports dual-channel.

What does the 2133MHz rating deliver in a live server?

The module runs at 2133MHz with CL15 timing, giving a peak bandwidth of 17000 MB/s; actual throughput depends on your CPU memory controller and the number of populated channels.

Is the DDR4 288-pin ECC UDIMM interface compatible with registered DIMM slots?

No — this is an unbuffered ECC UDIMM (288-pin) and will not work in slots that require registered or load-reduced DIMMs; verify your motherboard accepts unbuffered ECC before buying.
