I’ve been using this Dell Optiplex for awhile now. It acts as my spare rig to use while I’m benching my other one, and I also use it for word processing and other simple tasks.

I was just looking at the CPU-Z screen out of curiosity today, when I realized that an overclock on this machine is potentially possible. I was reminiscing on my A64 4200+ X2 HP days, when I managed to overclock the CPU 300MHz over stock using nothing but software (my very first overclock). Eventually I went on the net and grabbed SetFSB and started going through each PLL one by one, until I found on that worked on this particular chipset.

Its sort of lucky that it worked, considering Dell computers are built using proprietary components. The possibility of overclocking these in the first place are because the motherboards are based on retail market chipsets, and utilize some of the same PLL’s as a few boards out there.

I basically did this for all the people who thought OEM clocking wasn’t possible. I assure you, it can be done. Maybe some people using Dell’s will find this helpful as well.
