64GB DDR4 Server Memory

Key takeaways

• 1,349 listings match this collection right now.
• A 64GB RDIMM reaches that capacity using higher-density DRAM die on a dual-rank module, while a 64GB LRDIMM reaches it with a data buffer chip across a quad-rank design.
• Third-generation Xeon Scalable and EPYC Rome platforms qualify 64GB RDIMM at 3200, while earlier DDR4 platforms need the buffered LRDIMM version to reach the same capacity.
• Populating every channel with 64GB modules pushes a two-socket DDR4 platform toward its maximum per-socket capacity, so slot count on the board becomes the practical limit, not budget.
