64GB DDR5 Server Memory

Key takeaways

• 529 listings match this collection right now.
• 64GB DDR5 modules run as dual-rank parts built from 16Gb DRAM dies, since no single-rank 64GB build exists yet the way it does at the 32GB capacity below it.
• Fourth-generation Xeon Scalable and EPYC 9004 platforms both list 64GB RDIMM as a supported capacity, though the maximum modules per channel differs between the two processor families.
• 64GB exists only as registered RDIMM in the DDR5 lineup; unbuffered UDIMM options stop at the 32GB capacity below it, since single-socket boards do not yet support that density unbuffered.
