  • 64GB capacity supports demanding server workloads

  • 2Rx4 organisation improves rank-level parallelism
  • RDIMM form factor fits registered DIMM slots
  • New condition ensures full manufacturer specification compliance

Hynix 64GB RDIMM 3200MT/s module

This Hynix module provides a single 64GB 2Rx4 RDIMM operating at 3200MT/s. It is intended for servers or workstations that support registered DIMMs and need high-density memory in one slot. Buyers looking for unbuffered UDIMMs for consumer desktops cannot use this part.

Installing the RDIMM in a compatible slot

Align the notch with the keyed slot, press down evenly until both retention clips click, and confirm the system recognises the full 64GB at 3200MT/s. A common issue is installing registered memory in a motherboard that only accepts unbuffered DIMMs, which prevents the system from posting.

Registered DIMM form factor with 2Rx4 organisation

The module uses a registered DIMM form factor with a 2Rx4 rank arrangement, which determines compatibility with the memory controller. Verify that your platform supports registered memory and this rank configuration before purchase.
