NEMIX RAM 48GB DDR5 4800 CL40 1.1V 2Rx8 UDIMM ASUS Z890 APEX memory upgrade

SKU CH-6AF1-P3CFB

A 48 GB DDR5 module running at 4800 MHz with CL40 latency and 1.1 V operation for ASUS ROG Maximus Z890 APEX motherboards

  • Capacity48GB
  • SpeedDDR5 4800 (PC5 38400)
  • ECCNo
  • Buffered/RegisteredUnbuffered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V

Capacity 48GB

  • 48 GB capacity doubles memory headroom for heavy multitasking
  • DDR5 4800 speed moves data at PC5-38400 bandwidth
  • 10 V operation reduces power draw versus higher-voltage modules
  • 2Rx8 dual-rank layout increases density inside a single slot
  • 288-pin UDIMM form factor fits the ASUS Z890 APEX motherboard

Compatibility Scope

This 48GB DDR5 UDIMM is validated for the ASUS ROG Maximus Z890 APEX motherboard. It targets builders and IT professionals who need a single high-density module for that specific platform. The unbuffered, non-ECC design matches the board's consumer memory architecture.

Fit and Exclusions

The module suits users upgrading the named Z890 APEX system with one 48GB stick at 4800 MT/s. Buyers whose boards require registered or ECC memory cannot use this part. Systems that only support lower maximum density per slot or a different DDR generation are also incompatible.

Deciding Specification

The 48GB capacity in a single 288-pin 2Rx8 UDIMM running at 1.10V CL40 determines whether this upgrade fits the target board. Matching that exact density, rank structure, voltage and latency to the motherboard's qualified vendor list is the single check that confirms compatibility.

Questions about this item

What does the 4800 MT/s rating mean once this module is installed in the ROG Maximus Z890 APEX?

The board will run this kit at DDR5-4800 with CL40 timings at 1.1 V, delivering the rated PC5-38400 bandwidth without manual tuning.

Which DDR5 standard and pin layout does this 48 GB stick use?

It follows the JEDEC DDR5 specification as a 288-pin unbuffered UDIMM, so it fits any consumer DDR5 slot keyed for non-ECC memory.

What physical space and slot type are needed to mount this module?

A single 288-pin DDR5 UDIMM slot on the motherboard; the module has no heat spreader, so it fits under standard CPU coolers.
