Overview

The NEMIX RAM 128GB kit targets a specific buyer: someone populating a Supermicro H13SSW server board and unwilling to gamble on mismatched memory. It arrives as four 32GB modules of DDR5-6400 (PC5-51200), each a 2Rx8 dual-rank DIMM running at 1.1V with CL52 timing on the 288-pin Registered ECC form factor. The pitch is precision. Rather than a generic stick that merely fits the slot, this kit is spec-matched to the rank, voltage, and timing a server memory controller expects, so the system recognizes the full capacity and runs it at rated speed.

Construction follows enterprise conventions. The Registered (buffered) architecture places a register between the controller and the DRAM, offloading the controller so every slot can run fully populated without instability. ECC support adds another layer, catching and correcting single-bit errors before they surface as corrupted data or a surprise reboot in production. Practical ownership comes with a caveat NEMIX states plainly: memory support varies by model, so you should consult your motherboard manual for supported capacities and approved population order before installing. A lifetime replacement warranty and free US-based technical support round out the package, which matters when the hardware in question is meant to stay online.

Key Features

EXACT-MATCH UPGRADE — 128GB (4X32GB) kit DDR5-6400 (PC5-51200), 2Rx8 Registered ECC, 1.1V, CL52, 288-pin. The precise rank, voltage, and timing your server's memory controller expects, so it's recognized at full capacity and runs at its rated speed.

VERIFIED FITMENT — Compatible with the Supermicro H13SSW motherboard. The 288-pin Registered (RDIMM) form factor this board requires — not a UDIMM or SODIMM. 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 — Server 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 288-pin Registered ECC (RDIMM) memory designed for server boards. NEMIX specifies it is not a UDIMM or SODIMM, so it requires a board that accepts RDIMM modules.
Yes. NEMIX lists the kit as compatible with the Supermicro H13SSW, matching the 288-pin Registered form factor that board requires for its memory slots.
CL52 is the rated timing for this DDR5-6400 registered ECC kit. Relaxed latencies are a common tradeoff for reaching higher DDR5 data rates on buffered server memory.
The buffered Registered architecture offloads the memory controller so slots can run fully populated, while ECC detects and corrects single-bit errors on the fly to help prevent silent data corruption.
Yes. NEMIX advises consulting your system or motherboard manual for supported capacities, approved DIMM population order, and installation steps, since support varies by model.
It is backed by a lifetime replacement warranty and free US-based technical support, according to NEMIX.
