Lenovo 4X77A77495 16GB DDR4 3200 ECC Desktop RAM

16GB DDR4 3200 ECC DIMM for servers

This Lenovo TruDDR4 module delivers 16GB of dual-rank memory at 3200 MHz with ECC protection. It is built for server platforms that require registered-style reliability in a standard 288-pin DIMM form factor. The 1.20V operating voltage keeps power draw low while maintaining the rated PC4-25600 bandwidth. System builders targeting data-integrity workloads will find the specification a direct match.

Single 288-pin module with XMP 2.0 profile

The stick occupies one DIMM slot and presents an Intel XMP 2.0 profile so the platform can configure the rated 3200 MHz speed automatically. Dual-rank organisation means the memory controller sees two logical ranks per channel, which can improve utilisation on compatible server chipsets. ECC circuitry corrects single-bit errors without halting the system, freeing the OS from silent data corruption. No additional cooling or voltage adjustment is required beyond the rated 1.20V.

ECC and XMP 2.0 change error handling and setup

With ECC enabled the firmware logs and corrects single-bit flips, reducing unplanned downtime for always-on services. The bundled XMP 2.0 profile lets the BIOS apply the validated 3200 MHz timing set in one step, removing manual frequency and latency tuning. Builders who need non-ECC consumer memory or speeds beyond 3200 MHz should look elsewhere, as this module is fixed at the rated specification.
