# 长鑫存储 Advances DDR5 Chips to 32Gb, Lists 12,800Mbps MRDIMMs By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/55504 Published: 2026-11-12T14:29:55.000Z Updated: 2026-11-12T14:29:55.000Z Section: Technology > RDIMMs cover 32GB to 128GB, with rates from 5,600Mbps to 8,000Mbps. The MRDIMM line covers 128GB and 192GB capacities, with rates up to 12,800Mbps. 长鑫存储 has advanced its DDR5 memory chips from 24Gb to 32Gb, while its registered DIMM (RDIMM) and multi-ranked DIMM (MRDIMM) lines span capacities up to 192GB and rates up to 12,800Mbps. RDIMMs cover capacities from 32GB to 128GB, with data rates ranging from 5,600Mbps to 8,000Mbps. The MRDIMM line covers 128GB and 192GB capacities, with rates reaching 12,800Mbps. That top rate matches the rating for SMART Modular’s [DDR5-12800 MRDIMMs](). The design treats two physical memory ranks as one logical rank and is designed to increase bandwidth compared with standard RDIMMs. ## Links in this article - [DDR5-12800 MRDIMMs](https://www.tokenpost.com/news/technology/47658)
