NEMIX RAM 8GB DDR4 3200 CL22 1.2V 288-pin UDIMM for MSI B550 memory upgrade

SKU CH-BFEV-2WN5S

8GB DDR4 3200 CL22 1.2V UDIMM module validated for MSI B550 motherboards

  • Total capacity8 GB
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Buffer typeUnbuffered
  • Rated voltage1.2 V
  • 8 GB capacity adds responsive multitasking headroom
  • DDR4 3200 speed feeds data to the CPU faster
  • CL22 latency keeps timing tight for smooth operation
  • 20 V operation reduces power draw and heat
  • 288-pin UDIMM fits MSI B550 boards directly

Targeted DDR4 upgrade

This 8 GB DDR4 3200 module is built for the MSI MAG B550 Tomahawk MAX WiFi motherboard. It delivers a straightforward capacity increase for desktop users who need more memory for everyday workloads.

Single-slot UDIMM fit

The 288-pin unbuffered DIMM installs in one standard DDR4 slot and runs at 1.2 V with CL22 timing. No heat spreader is fitted, so clearance around larger CPU coolers remains unaffected.

Replaces slower or smaller DDR4

Swapping out lower-speed DDR4 or a 4 GB stick raises bandwidth to PC4-25600 and doubles capacity in a single slot. The jump is worthwhile when current memory limits multitasking or forces frequent paging.

Questions about this item

How does the CL22 latency affect sustained throughput on the NEMIX DDR4 3200 module?

The CL22 timing sets the minimum delay between column accesses, so sustained bandwidth is limited by the 22-cycle wait at each row activation.

Does the 1.20 V UDIMM run hotter or louder than lower-voltage DDR4 when installed in an MSI B550 board all day?

At 1.20 V the module draws standard DDR4 power and has no heat spreader, so it relies on case airflow and produces no audible noise.

What motherboard slot and chipset must already be present for this 288-pin DDR4 3200 kit to work?

The kit requires a 288-pin DDR4 UDIMM slot on an MSI B550 chipset motherboard such as the MAG B550 Tomahawk MAX WiFi.
