6 ounces!! I have a 3 gram tube and it should last at least 20 applications for an Athlon chip. Just a dab will do ya. Spread it with a razor thinly on the processor die only (the center of the chip), just enough to leave a thin coat you can almost see through. Then dab a bit on the heatsink and rub it in, then off with a clean lint-free cloth. It's called tinning and you may see a hint of silver on the heatsink when you're done. It's only meant to fill in the microscopic pits and valleys on the heatsink.
