NEMIX 16GB DDR4-3200 UDIMM for ASUS B550-F

This 16GB DDR4-3200 module targets desktop builders upgrading an ASUS ROG Strix B550-F Gaming WiFi II motherboard. It delivers standard PC4-25600 performance at 1.2V without ECC or a heat spreader. The single-rank 2Rx8 organisation fits the board’s four DIMM slots. Buyers needing ECC, registered buffering or speeds beyond 3200 MT/s should look elsewhere.

DDR4-3200 CL22 practical limits

The module runs at the JEDEC DDR4-3200 base speed with CL22 latency and 1.2V operation. No XMP profile or higher frequency bin is specified, so the memory will not exceed 3200 MT/s without manual tuning. Maximum system capacity remains defined by the motherboard’s four-slot design and chipset memory controller. Builders requiring lower latency or overclocking headroom cannot rely on this part.

Tool-free DIMM installation

Installation follows the standard 288-pin UDIMM procedure: align the notch, press firmly until the retention clips click. The low-profile bare PCB clears most CPU coolers, but very large tower coolers may overhang the first slot. Common issues include seating the module incompletely or mixing ranks across channels, which can prevent the system from posting at the rated speed.

Questions about this item

Should I choose the 16 GB 3200 MHz CL22 module or look for a different capacity or speed?

This module provides 16 GB at DDR4 3200 with CL22 timing; select it when your board supports DDR4 3200 and you need a single 16 GB stick, otherwise match the capacity and speed your motherboard specifies.

What does the 3200 MHz rating actually deliver once installed in my desktop?

The memory runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2 V, giving the rated transfer rate when the motherboard enables the corresponding JEDEC profile.

Does the 288-pin UDIMM interface limit the speed or features I can use?

The 288-pin DDR4 UDIMM form factor carries the DDR4 3200 signal unbuffered and non-ECC; it does not add extra limits beyond the DDR4 standard and the motherboard's memory controller.
