Support level key:
  • S = simulation support
  • C = compilation support
  • T = timing support
  • H = hardware support

  • X = supported feature.
  • * = Intel no longer supports custom-built DIMMs.
    • Intel® Agilex™ devices do not support custom DIMMs.
    • Intel does not provide support for customer-built DIMMs.
    • Intel does not provide support for memory down where components are laid out with a registered clock driver (RCD) chip for clock/address/command buffering or data buffering.
    • Intel continues to provide support for off-the-shelf JEDEC-compliant DIMMs and memory down without RCD or data buffering, as well as clamshell topology, supported subject to Intel's board design guidelines.
  • An empty table cell indicates that the feature is not currently supported.

  • 1 = No hardware validation for x16 DRAM module UDIMM.
  • 2 = 3DS 2H is not hardware validated. 3DS 4H is hardware validated.
  • 3 = x16 twin-die and dual-die package (DDP) is not currently supported; support is planned in a future version of the Intel® Quartus® Prime software.
  • 4 = Dual-rank x8 DDP is not currently supported; support is planned in a future version of the Intel® Quartus® Prime software.
  • 5 = Clamshell dual-rank x16 is not currently supported; support is planned in a future version of the Intel® Quartus® Prime software.
  • 6 = Support is planned in a future version of the Intel® Quartus® Prime software.
  • 7 = Configuration with x8 is not hardware validated.
  • 8 = No hardware validation in this release of the Intel® Quartus® Prime software.
