Sockets 754 and 939 are used by Sempron socket 754, Athlon 64, Athlon 64 FX and Athlon 64 X2 processors.

First make sure both surfaces – of processor and cooler - are clean and free from impurities, as we show in Figure 20.

Using a small spatula (which can be made out by cutting a piece of the hard transparent plastic from the processor box), apply some thermal grease on the center of the processor. Don’t worry about covering the whole processor area because the cooler pressure will make it uniform. See Figures 21 and 22.
