Overview

The NEMIX RAM 256GB kit is aimed squarely at operators building or upgrading a server around the GNR2D16-2T motherboard. It arrives as four 64GB modules, DDR5-6400 rated (PC5-51200), in the 2Rx4 ECC Registered RDIMM format at 1.10V with CL52 timing. This is not a general-purpose desktop upgrade. It is a spec-matched set intended to be recognized at full capacity and to run at its rated speed, because the rank, voltage, and timing line up with what a compatible memory controller expects. For anyone populating all the slots on this specific board, the appeal is a single, exact-match purchase.

On the practical side, the registered (buffered) architecture is what makes fully populated, high-capacity configurations viable, offloading the memory controller so every slot can be filled. ECC adds a further layer, correcting single-bit errors before they surface as corrupted data or unexpected reboots — the kind of stability enterprise deployments are built around. NEMIX is clear that memory support varies by system, so the manual should be consulted for supported capacities and the approved population order before purchase. Ownership is backed by a lifetime replacement warranty and free US-based technical support, a meaningful cushion given the cost and role of server memory at this tier.

Key Features

EXACT-MATCH UPGRADE — 256GB (4X64GB) kit DDR5-6400 (PC5-51200), 2Rx4 ECC Registered RDIMM, 1.10V, CL52, 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 GNR2D16-2T motherboard. The RDIMM form factor this board requires. Spec-matched to your board's memory-population rules.

ENTERPRISE STABILITY — Registered (buffered) architecture offloads the memory controller so every slot runs fully populated at full capacity, while ECC catches and corrects single-bit errors on the fly — stopping silent data corruption and unplanned reboots before they reach production.

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

No. This is a 2Rx4 ECC Registered RDIMM kit that requires a server board supporting registered memory, such as the GNR2D16-2T it is spec-matched to. Standard desktop boards use unbuffered DIMMs.
The kit ships as four 64GB DDR5 RDIMMs (4x64GB), letting you populate all four slots on a compatible board in a single matched purchase rather than mixing separate sticks.
CL52 is the rated timing for this DDR5-6400 registered server module. Enterprise ECC RDIMMs prioritize stability and capacity at rated speed over the tighter latencies marketed for desktop kits.
Likely yes. NEMIX advises consulting your system or motherboard manual for the approved DIMM population order and supported capacities before installation, since these rules vary by board model.
It is backed by a lifetime replacement warranty and free US-based technical support, which is meaningful reassurance for a high-value server memory purchase of this capacity.
Each module runs at 1.10V in the 288-pin ECC Registered RDIMM form factor, matching the electrical and physical spec a compatible server memory controller expects.
