32GB DDR4-3200 ECC UDIMM for Lenovo servers

This 32GB DDR4-3200 module uses a 2Rx8 ECC UDIMM layout to provide error-correcting memory for compatible Lenovo systems. It operates at the PC4-25600 standard and is built with major-brand chipsets. The part is fully equivalent to Lenovo part number 4X77A77496.

Fits UDIMM slots that accept 2Rx8 registered ECC

Installation requires a motherboard with UDIMM slots supporting DDR4-3200 ECC memory and a 2Rx8 rank configuration. The module frees the system from single-rank density limits by delivering 32GB in a single slot. Compatibility is validated against the Lenovo 4X77A77496 specification.

Sustains 3200 MT/s throughput

The 2Rx8 organisation allows the memory controller to interleave accesses across two ranks, maintaining bandwidth during extended workloads. Error-correction runs on every cycle without reducing the rated 3200 MT/s data rate. The major-brand chipset ensures stable operation at the PC4-25600 timing grade.

Questions about this item

Does the 2Rx8 organisation limit how many of these 32GB modules I can populate per channel?

The 2Rx8 rank presents two logical ranks per DIMM, so each channel can accept fewer modules than a single-rank part before hitting the platform rank limit.

What is the typical power draw and thermal output when the kit runs at 3200 MT/s continuously?

Standard DDR4-3200 2Rx8 ECC UDIMMs draw roughly 3 to 5 watts each under sustained load and run warm but within JEDEC thermal limits.

Which motherboard feature must already be present for this ECC UDIMM to function?

The board must support unbuffered ECC DDR4 memory and have a compatible UDIMM slot population.
