Capacity and Compatibility

This 64GB kit delivers two 32GB DDR5 5600 ECC unbuffered UDIMMs built for SuperMicro BH4SR2-25G and BH4SRG motherboards. The modules run at 1.1V with CL46 latency and use a 2Rx8 organisation on a standard 288-pin interface. They provide error-correcting memory for workloads that require data integrity.

Suitability and Limits

Builders upgrading or repairing the listed SuperMicro platforms can install this kit directly. Systems that need registered DIMMs, non-ECC memory, or a different DDR generation will not accept these modules. The 32GB per module density also means boards limited to lower single-DIMM capacities cannot use the kit.

Deciding Specification

The key figure is the DDR5 5600 (PC5-44800) ECC unbuffered UDIMM standard at 1.1V with CL46 timing. Match this exact specification against the motherboard memory QVL before purchase to confirm compatibility.

Questions about this item

Does my SuperMicro BH4SR2-25G or BH4SRG motherboard need to support DDR5 5600 ECC unbuffered UDIMMs for this kit to work?

Yes, the motherboard must accept DDR5 5600 ECC unbuffered UDIMMs at 1.1V with 288-pin layout; the kit is validated for those exact SuperMicro models.

Will the CL46 2Rx8 modules run at their rated 5600 speed if the board only officially supports a lower DDR5 data rate?

The modules will operate at the highest speed the motherboard allows; if the board caps DDR5 below 5600, they will downclock automatically while keeping ECC and 1.1V operation.

How can I confirm the kit is running as intended after installation?

Check BIOS or OS memory reporting for 64 GB total, DDR5 5600 (PC5-44800), CL46 timings, ECC active, and 1.1V voltage on both 2Rx8 modules.
