128GB DDR5 Server Memory

Key takeaways

• 285 listings match this collection right now.
• 128GB DDR5 modules use 3D-stacked (3DS) die construction to reach that capacity within a standard dual-rank or quad-rank module footprint.
• Fourth-generation Xeon Scalable and EPYC 9004 platforms both qualify 128GB RDIMM, but the maximum number of these higher-rank modules per channel is set by the platform, not the module.
• A 128GB module's higher rank count means it has to match the rank of any other module sharing its channel, since mismatched ranks are not supported by the memory controller.
