16 GB DDR4-2933 ECC registered RDIMM with 2Rx8 organisation and 1.2 V operation
This 16 GB DDR4-2933 registered DIMM is built for Lenovo servers that require ECC error correction. It operates at 1.2 V and uses a 2Rx8 organisation with 288 pins. The module suits administrators who need guaranteed compatibility with OEM part 01AG631.
Running at the JEDEC-standard 1.2 V, the module draws typical DDR4 power without extra cooling demands. The registered buffer reduces electrical load on the memory controller, helping stability in multi-DIMM configurations. Acoustic impact is negligible because the part has no moving components.
Orders are fulfilled with identically matched modules from Samsung, SK Hynix or Micron so that multi-channel populations stay in step. The lifetime warranty covers the memory for as long as the system remains in service. No additional software or accessories are included.

Align the notch on the module with the key in the slot, press down until the side clips snap shut, and verify the registered module is seated in the correct channel order for your server.
No routine maintenance is required; if a correctable error count rises or an uncorrectable error appears, replace the 16 GB module with an identical 2Rx8 part.
The thermal and timing envelope of the 2933 MT/s registered DIMM is reached before voltage or capacity limits under continuous server workloads.
