Overview

The NEMIX RAM 128GB kit targets a specific buyer: someone running an ASUS Prime AM5 motherboard who needs the most unbuffered memory the platform will accept. It bundles four 32GB DDR5 modules rated at 5600MHz (PC5-44800), each using a 2Rx8 layout, a modest 1.10V, and CL46 timings. These are 288-pin UDIMMs, the unregistered form factor consumer boards use, which distinguishes this from registered memory intended for enterprise servers despite the "server memory" label. The appeal is straightforward. Rather than cross-referencing spec sheets, buyers get a kit NEMIX has matched to the rank, voltage, and timing its listed boards expect.

On the practical side, the kit is built and tested to run at its full rated speed and capacity in the systems it is spec-matched for, and NEMIX names them explicitly, from the X870-P-CSM to the B650EM-A WIFI-CSM. Ownership details are reassuring: a lifetime replacement warranty and free US-based technical support come standard. NEMIX is candid that memory support varies by model, urging buyers to consult their motherboard manual for supported capacities, approved DIMM population order, and installation steps before purchase. That caution is worth heeding with any four-module, dual-rank configuration, where BIOS revisions and controller behavior can affect whether every kit reaches its rated speed.

Key Features

EXACT-MATCH UPGRADE — 128GB (4X32GB) kit DDR5-5600 (PC5-44800), 2Rx8 Non-ECC UDIMM, 1.10V, CL46, 288-pin. The precise rank, voltage, and timing your system's memory controller expects, so it's recognized at full capacity and runs at its rated speed.

VERIFIED FITMENT — Compatible with the ASUS PRIME X870-P-CSM / PRIME B850-PLUS WIFI-CSM / PRIME B850M-A WIFI-CSM / PRIME B850M-A-CSM / PRIME B840-PLUS WIFI-CSM / PRIME B840M-A WIFI-CSM / PRIME B650EM-A WIFI-CSM motherboards. Unbuffered non-ECC UDIMM — the memory type and form factor these boards natively support. Spec-matched to your board's memory-population rules.

THE RIGHT MEMORY TYPE — This is unbuffered non-ECC UDIMM, not ECC, RDIMM, or LRDIMM. Consumer and workstation chipsets are specified for unbuffered modules, and installing a registered or error-correcting module where the platform expects UDIMM is a common cause of a no-POST. Match the memory type your board calls for.

CHECK YOUR CONFIG — System and motherboard memory support varies by model. Consult your system or motherboard manual for supported capacities, approved DIMM population order, and installation steps before purchase.

LIFETIME SUPPORT — Backed by a lifetime replacement warranty and free US-based technical support.

Frequently Asked Questions

NEMIX lists compatibility with ASUS Prime models including the X870-P-CSM, B850-PLUS WIFI-CSM, B850M-A WIFI-CSM, B840-PLUS WIFI-CSM, B650EM-A WIFI-CSM and related CSM boards.
It is unbuffered UDIMM memory in the 288-pin form factor. Despite the server memory label, it uses the unregistered modules that consumer ASUS Prime boards require, not registered DIMMs.
The kit runs at DDR5-5600 (PC5-44800) with CL46 latency, a 2Rx8 rank layout, and 1.10V operating voltage across all four 32GB modules.
Yes. NEMIX advises consulting your motherboard manual for supported capacities, approved DIMM population order, and installation steps, since memory support varies by model.
It is backed by a lifetime replacement warranty and free US-based technical support, so assistance is available for the life of the modules.
