Samsung 128GB DDR5 4800MHz PC5-38400 ECC RDIMM 4Rx4 2S2Rx4 (EC8 10x4) Quad Rank 1.1V Review & Specifications
The Samsung 128GB DDR5 4800MHz PC5-38400 ECC RDIMM 4Rx4 2S2Rx4 (EC8 10x4) Quad Rank 1.1V from Samsung is a RAM module, identified by part number M321RAGA0B20-CWK. This module offers a total capacity of 128 GB and utilizes DDR5 ECC Reg memory type. It comes in a (1X128GB) kit configuration and features a DIMM form factor. It supports ECC (Error-Correcting Code), making it suitable for servers and critical systems.
Performance
Operating at 4800 MT/s with highly conservative ECC timings of 40, this memory module is engineered for maximum compatibility and data integrity. With a benchmark performance of 71.5%, it is best suited for legacy platforms, low-power server environments, or systems where stability and longevity take absolute priority over performance.
Cost-Effectiveness
From a cost-efficiency perspective, this RAM module offers low value, priced at $29.6 per gigabyte. The overall combined performance-to-price ratio, which evaluates both speed and cost per GB, is 28.4%. This makes it a relatively poor value in this category. Given that its performance is not top-tier, users might find better-performing alternatives at a similar or even lower price point, making this module less appealing in terms of overall value.
