A-Tech 16GB DDR4 2933MHz ECC RDIMM 1Rx4 for IBM-Lenovo 4ZC7A08707 4ZC7A08740 Server Memory

16GB DDR4 ECC RDIMM for IBM-Lenovo servers

This 16GB DDR4 2933MHz ECC registered DIMM is built for IBM-Lenovo systems using part numbers 4ZC7A08707 and 4ZC7A08740. It targets administrators who need validated server memory that meets OEM specifications for data-integrity workloads. The module uses major-brand chips and runs at standard 1.2V DDR4 voltage.

Replaces slower DDR4 or non-ECC modules

Upgrading from lower-speed DDR4 or unbuffered non-ECC memory adds error correction and registered signalling that multi-socket servers require. The jump is worth it when your platform demands registered DIMMs and you need the 2933MHz data rate to match the CPU memory controller. Systems limited to lower speeds or unbuffered DIMMs cannot use this module.

16GB single-rank capacity with CL21 latency

The 1Rx4 organisation delivers 16GB in one 288-pin module at CL21, giving dense capacity per slot for virtualisation, databases and compute tasks. Headroom exists until the memory controller reaches its maximum supported rank count or total capacity per channel. Workloads exceeding the platform's DIMM-slot limit or total memory ceiling will need higher-density modules or additional channels.
