  • ECCYes

Capacity 32GB

Struck-through versions exist but are not stocked here.

  • 32 GB capacity expands server memory for heavier workloads
  • ECC registered design detects and corrects data errors for reliability
  • DDR4 3200 speed with CL22 latency delivers responsive throughput
  • 2 V operation reduces power draw and heat output
  • Validated for Gigabyte E252-P30, E252-P31, G242-P31, G242-P32, G242-P33 systems

Server ECC RDIMM upgrade

This 32 GB DDR4 ECC Registered DIMM operates at 3200 MHz with CL22 latency and 1.2 V power. It is built for Gigabyte E252-P30, E252-P31, G242-P31, G242-P32 and G242-P33 server and workstation platforms.

Single-module capacity boost

The kit provides one 2Rx4 288-pin module that adds 32 GB of registered ECC memory without mixing with unbuffered or load-reduced types. JEDEC and RoHS compliance ensures a warranty-safe upgrade for compatible systems.

Verify registered ECC support

Confirm your motherboard accepts DDR4 ECC Registered RDIMMs and matches the listed Gigabyte model numbers. This module will not work in standard desktop boards or in slots that require unbuffered or load-reduced memory.

Questions about this item

Will the 288-pin DDR4 ECC RDIMM need any firmware updates or thermal-pad replacements over its service life?

No firmware or thermal-pad maintenance is required; the module has no heat spreader and runs at standard 1.2 V JEDEC voltage for its full lifetime.

What sustained-load limit appears first on this 3200 MHz CL22 registered DIMM?

The registered buffer and ECC logic fix latency at CL22, so memory-controller throughput — not module temperature — becomes the first bottleneck under continuous server workloads.

How much extra heat or power does the 2Rx4 32 GB stick add when the Gigabyte E252 or G242 runs 24/7?

At 1.2 V the module draws only nominal DDR4 power and, lacking a heat spreader, relies on chassis airflow; no measurable noise or thermal rise occurs versus lower-speed 2133/2400/2666/2933 MHz operation.
