Know before you buy
No, this is a Registered DIMM (RDIMM) designed specifically for server and workstation motherboards. It is not compatible with standard consumer desktop motherboards that require unbuffered memory.
Registered ECC memory includes a register between the memory modules and the system's memory controller, which helps stabilize high-capacity memory configurations. The ECC (Error Correction Code) feature automatically detects and fixes data corruption, ensuring higher reliability for critical server tasks.
For optimal stability, we recommend matching the speed, capacity, and rank of your existing memory modules. Mixing different types or speeds can lead to system instability or force the memory to run at the speed of the slowest module.
This module has been pulled from a working environment, thoroughly tested for performance, and verified to meet original manufacturer specifications. It is fully functional and backed by a 3-year warranty to ensure long-term reliability.
No, this module is designed to operate within standard thermal parameters for server environments without a heat spreader. Ensure your server chassis has adequate airflow to maintain optimal operating temperatures.
