Socket 775 Processors

Socket LGA775 is used by Pentium 4, Pentium D and Celeron D processors. The way of attaching it is very different from other types of processors. In socket LGA775, the pins are on the motherboard and not on the processor. That’s why the motherboard officially supports only 20 installation and removal operations. After that, there’s no guarantee that the board will work properly. So, don’t unnecessarily remove your socket LGA775 processor from the motherboard!

First make sure both surfaces of the processor and the cooler are clean and free from impurities and that the processor is well-installed.

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

Next, install the processor cooler, as we’ll show in the next page.
