128GB DDR5 kit for Supermicro BH4SR2-25G

This 128GB kit contains four 32GB DDR5 5600 modules built for the Supermicro BH4SR2-25G motherboard. Each stick runs at 1.1V with CL46 timings in a 2Rx8 unbuffered UDIMM layout. The PC5-44800 rating matches the board's native memory specification.

Suited for memory-heavy workloads on the target

Workstations and servers using the BH4SR2-25G that need maximum capacity per slot will use this kit directly. Systems requiring ECC protection or registered modules cannot use this non-ECC unbuffered memory. Builders needing lower-density sticks or a different pin layout should select another product.

Steady throughput at rated voltage and timings

Under sustained load the four modules operate at the specified 1.1V and CL46 without thermal throttling from a heat spreader. The 2Rx8 organisation keeps bandwidth consistent across all populated channels during long compute or virtualisation tasks.

Questions about this item

Does this 128 GB kit require a Supermicro BH4SR2-25G motherboard to work?

The kit is validated for the Supermicro BH4SR2-25G; other boards need DDR5 5600 UDIMM support, 288-pin slots, and 1.1 V operation.

Will my current DDR5 4800 modules run at their rated speed if I add this 5600 CL46 kit?

All installed DDR5 memory runs at the lowest common speed, so the 5600 CL46 modules will downclock to match 4800.

How can I confirm the system is using the full 128 GB at DDR5 5600 CL46 after installation?

Check BIOS or an OS tool such as Task Manager or dmidecode; it should report 128 GB, 5600 MT/s, and CL46 timings.
