NEMIX RAM 48GB DDR5 5600 ECC UDIMM SuperMicro memory upgrade

SKU CH-QB9A-QEJZS

A 48 GB DDR5 ECC UDIMM running at 5600 MHz with CL46 latency and 1.1 V operation for SuperMicro BH4SR2-25G and BH4SRG motherboards

  • Total capacity48 GB
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Buffer typeUnbuffered
  • Rated voltage1.1 V
  • 48 GB capacity expands server memory headroom for demanding workloads
  • DDR5 5600 speed delivers high bandwidth for data-intensive applications
  • ECC protection detects and corrects single-bit errors to maintain data integrity
  • 10 V operation reduces power draw compared to higher-voltage modules
  • Validated for SuperMicro BH4SR2-25G and BH4SRG motherboards for reliable compatibility

Capacity and platform fit

This 48GB DDR5 ECC UDIMM module is built for SuperMicro BH4SR2-25G and BH4SRG motherboards. It targets administrators expanding memory capacity in compatible server or workstation platforms.

Upgrade path from lower-capacity or slower DDR5

The single 48GB stick replaces smaller DDR5 modules or slower DDR5 speeds to raise total system memory. The jump is worthwhile when workloads exceed current capacity or when 5600 MT/s bandwidth better matches the platform's supported data rate.

Sustained-load behaviour with ECC and 1.1V operation

Error-correcting code protects data integrity during continuous operation. The module runs at 1.1V with CL46 latency and a 2Rx8 organisation, delivering stable throughput under prolonged server workloads without a heat spreader.

Questions about this item

Will the 288‑pin DDR5 module fit the DIMM slots on my SuperMicro BH4SR2‑25G motherboard?

Yes, the 288‑pin DDR5 ECC UDIMM matches the slot layout of the BH4SR2‑25G and BH4SRG boards.

What is the correct way to seat this single 48GB stick, and what step do people often miss?

Align the notch with the slot key, press down firmly until both side clips click, then verify in BIOS that the module runs at 5600 MT/s and 1.1 V.

Does the lack of a heat spreader mean I will need to add cooling or replace the module sooner?

No, the module is rated for 1.1 V operation without a spreader; standard case airflow is sufficient and no scheduled replacement is required.
