OWC Memory for Mac Pro 2013 fully meets Apple's specifications with special attention to proper thermal specifications.

Important Compatibility Note:
This RAM is exclusively designed for the Late 2013 Mac Pro (Model Identifier: MacPro6,1).

  • It is NOT compatible with Windows PCs, iMac, MacBook, Mac Mini, or any other Mac models.
  • Please confirm your device's model and year of release before purchasing.
  • Note: Although this RAM is rated at 1866MHz, Mac systems read it as 1867MHz due to system rounding. This is completely normal and does not affect performance.

If you're unsure about compatibility, contact us for assistance.
