Four bare green DDR5 UDIMM sticks in a kit

NEMIX RAM

NEMIX RAM 192GB (4×48GB) DDR5 4800 CL40 1.1V 2Rx8 UDIMM memory upgrade

SKU CH-AM73-BF4RR

A 192 GB DDR5 kit of four 48 GB UDIMM modules running at 4800 MT/s with CL40 latency and 1.1 V operation

  • Total capacity192 GB (4 × 48 GB)
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeUnbuffered
  • Rated voltage1.1 V

Capacity 192GB 4X48GB

  • 192 GB total capacity from four 48 GB modules
  • DDR5 4800 MT/s speed rated at PC5-38400 bandwidth
  • CL40 CAS latency at 1.10 V operating voltage
  • 2Rx8 dual-rank unbuffered UDIMM architecture
  • 288-pin DDR5 form factor validated for Gigabyte B650 motherboard

Capacity and platform fit

This kit delivers 192 GB of DDR5 memory in four 48 GB modules. It is validated for the Gigabyte B650 AORUS Elite AX motherboard and similar AM5 platforms. Builders who need eight DIMM slots or registered ECC modules cannot use this unbuffered UDIMM kit.

Thermals noise and power

Each module runs at the standard 1.1 V DDR5 voltage with CL40 latency at 4800 MT/s. The low voltage and lack of a heat spreader keep power draw modest and the sticks silent under typical desktop workloads. Sustained server-style loads may require additional case airflow because no thermal hardware is included.

Installed experience

The package contains only the four UDIMM sticks; no software, RGB controllers or extra cables are supplied. Installation is a straightforward seat-and-click process that takes minutes. Once fitted the system sees the full 192 GB capacity at the rated speed without further configuration.

Questions about this item

How do I install the 288-pin DDR5 UDIMM modules in the four slots on my B650 motherboard, and what step is often missed?

Align the notch on each 48 GB module with the slot key, press down firmly until the retention clips click on both sides, then confirm in BIOS that all 192 GB are detected at 4800 MT/s; the step often missed is fully seating both ends so the clips engage.

What maintenance or replacement will the 2Rx8 DDR5 4800 CL40 kit need over time?

No scheduled maintenance is required; keep the interior dust-free and ensure the CPU cooler clears the modules, and if a module fails it is replaced individually under the lifetime replacement warranty.

What limit appears first when the four 48 GB modules run sustained workloads at 1.1 V?

The CAS latency of CL40 at 4800 MT/s is the primary timing constraint; thermal throttling is unlikely without a heat spreader, so stability depends on the memory controller maintaining the rated voltage and timings under load.
