Compatibility Note:
- Vintage Legacy Desktop Hardware Only: Full-size 240-pin desktop DDR2 DIMM architecture. Please cross-reference your specific legacy motherboard and processor requirements before purchasing. These are classic mid-to-late 2000s desktop modules operating at a native 800MHz clock speed, making them ideal for high-end Windows XP or early Windows Vista retro gaming platforms like Intel Socket 775 or AMD Socket AM2 configurations. They require a motherboard chipset that explicitly supports 2GB high-density modules per slot. They are physically and electrically incompatible with older 184-pin DDR1 slots, newer 240-pin DDR3 layouts, or laptop SO-DIMM tracks.
