64 GB DDR5 ECC UDIMM kit for SuperMicro servers

This 64 GB kit contains four 16 GB unbuffered DDR5 modules rated at 5600 MT/s with CL46 latency. ECC protection detects and corrects single-bit errors, making it suitable for SuperMicro BH4SR2-25G and BH4SRG motherboards in server or workstation roles. The 1.1 V operating voltage matches the DDR5 baseline for these platforms.

No heat spreaders or extra software included

The modules ship without heat spreaders, relying on chassis airflow for cooling in dense configurations. No additional software, drivers or firmware utilities are bundled; the memory operates at JEDEC-standard timings once installed and recognised by the system BIOS.

288-pin UDIMM form factor fits compatible

Each module uses the standard 288-pin DDR5 UDIMM edge connector and a 1Rx8 organisation, so it seats directly in the memory slots of the listed SuperMicro motherboards. Builders who need registered DIMMs, higher capacities per slot, or support for other server platforms cannot use this kit.

Questions about this item

Will the 1Rx8 DDR5 modules need any firmware updates or reconfiguration after a BIOS change?

The kit runs at 1.1 V with standard JEDEC timings, so no firmware updates or manual reconfiguration are required after a BIOS change.

What limit appears first when the four 16 GB sticks run continuously at DDR5 5600?

The CL46 latency at 5600 MT/s is the primary timing constraint; sustained throughput is bounded by that CAS figure.

How much heat and power should I expect from the unbuffered ECC UDIMMs running all day?

Each module draws 1.1 V with no heat spreader, so thermal output stays low and total power scales with the four 1Rx8 sticks at 5600 speed.
