Good to know
  • Intel: Core desktop processors (12th-14th Gen, LGA1700) and Core Ultra desktop processors (Series 2, LGA1851) are not cross-compatible.
  • Core Ultra 200S processors support DDR5 only.
  • Intel: LGA1700 and LGA1851 mounting holes are in the same locations, so LGA1700 thermal solutions fit LGA1851 without modification. Intel says this covers mounting only; confirm thermal/power suitability with the cooler maker.
  • Noctua: all LGA1700-compatible Noctua coolers and mounting kits are also compatible with LGA1851.
  • Optional offset mounting (e.g. Noctua NM-IMB8 bars listed for the NH-D15 G2 on Core Ultra 9 285K / 7 265K) is a performance accessory, not required for fitment.
