- Vintage Laptop Hardware Only: Compact 200-pin laptop SO-DIMM architecture. Please cross-reference your specific legacy notebook or mobile workstation requirements before purchasing. These are classic mid-2000s modules operating at a native 667MHz clock speed, making them ideal for high-end Windows XP or early Windows Vista retro gaming notebooks (such as vintage Apple MacBook Intel Core 2 Duo eras, classic Dell Latitude D620/D630, or HP Compaq platforms). They require a motherboard chipset that explicitly supports 2GB high-density modules per slot. They are physically and electrically incompatible with standard 240-pin desktop DIMM slots, newer DDR3/DDR4 laptop tracks, or low-voltage layouts.
