48GB DDR5 5600MHz NZXT N7 B850 upgrade

This 48GB DDR5 5600MHz kit is built as an exact-match upgrade for the NZXT N7 B850 motherboard. It delivers the precise rank, voltage, and timing the board's memory controller expects for full-capacity recognition at rated speed. The 2Rx8 non-ECC unbuffered design suits desktop workloads from content creation to multitasking. Builders needing ECC or registered modules should look elsewhere.

288-pin UDIMM 1.10V CL46 no heat spreader

The 288-pin UDIMM form factor matches the NZXT N7 B850 slot requirements without adapter or converter. Major OEM chips from Samsung, Micron, or Hynix are tested at 1.10V and CL46 for stability at the specified data rate. Absence of a heat spreader keeps the module low-profile for tight cooler clearances. Systems requiring taller modules or active cooling on the DIMM will not be served by this design.

DDR5 5600MHz PC5-44800 capacity and speed step

Replacing slower DDR5 or lower-capacity kits with this PC5-44800 module raises both bandwidth and total memory headroom in a single step. The jump is worthwhile when the board's population rules allow the 48GB density and the workload benefits from the higher transfer rate. Builders constrained to lower speeds or smaller DIMM counts by their specific motherboard revision will not gain the full uplift.

Questions about this item

What DDR5 speed and PC5 bandwidth does this 48GB kit run at?

This kit operates at DDR5 5600, which is the PC5-44800 standard. The memory controller on the NZXT N7 B850 will recognise the 2Rx8 modules and run them at the rated 5600 MT/s without manual tuning.

Will the 288-pin UDIMM modules fit the NZXT N7 B850 motherboard slots?

Yes. The board uses standard 288-pin DDR5 UDIMM slots, and these modules are the exact unbuffered non-ECC form factor the manual specifies. No heat spreader means they clear most CPU coolers without height issues.

How do I install the kit so the board sees the full 48GB?

Power off, open the case, and insert the module into the primary slot indicated in the NZXT N7 B850 manual — usually the slot nearest the CPU. Press down until both retention clips click. A common mistake is seating only one side; verify both clips are locked before closing the case.
