NEMIX RAM MD44800-328K1 32GB DDR5 5600MHz CL46 2Rx8 1.1V UDIMM memory upgrade

SKU CH-128Q-N2KR2

32GB DDR5-5600 UDIMM with CL46 latency and 1.1V operation, built from major OEM chips for the ASRock B650M-C motherboard

  • Total capacity32 GB
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V

Size 32GB

  • 32 GB capacity doubles multitasking headroom for demanding workloads
  • DDR5 5600 MHz speed feeds data to the CPU at rated bandwidth
  • CL46 latency and 1.1 V voltage match the memory controller's exact timing
  • 2Rx8 288-pin UDIMM form factor fits the ASRock B650M-C motherboard slot
  • Major OEM chips from Samsung, Micron or Hynix tested for stability at rated specs

Exact-match upgrade for ASRock B650M-C

This 32 GB DDR5 module runs at 5600 MT/s with CL46 latency at 1.10 V. The 2Rx8 unbuffered UDIMM layout matches the memory controller expectations of the ASRock B650M-C motherboard so the system recognises the full capacity at rated speed.

Thermals noise and power draw

Operating at the standard 1.10 V DDR5 voltage keeps power draw low and heat output minimal during typical desktop workloads. With no heat spreader fitted the module relies on case airflow which is sufficient for its rated specification.

Lifetime support and verified fitment

The kit is validated for the target board using major OEM chips from Samsung Micron or Hynix and includes a lifetime replacement warranty plus free US-based technical support. Buyers needing ECC registered DIMMs or SODIMM form factors should look elsewhere.

Questions about this item

How do I install this 288-pin DDR5 UDIMM in my ASRock B650M-C motherboard, and which slot order do people often get wrong?

Align the module's notch with the slot key, press firmly until the latches click, and follow the manual's population sequence — usually slot A2 first, then B2 — rather than filling slot A1 alone.

What maintenance or replacement will this 32GB DDR5 5600MHz kit need over its service life?

No scheduled maintenance is required; keep the contacts clean and ensure airflow. If a module fails, the lifetime replacement warranty covers a direct swap for an identical 2Rx8 1.1V CL46 kit.

What limit appears first when this CL46 1.1V memory runs sustained workloads?

The CL46 latency at 5600 MT/s is the primary bottleneck; the fixed 1.1V operating voltage leaves no headroom for higher frequencies, so throughput plateaus at the rated PC5-44800 bandwidth.
