Yes! I give this Pentium III another spot on my channel. I tried to fix it before - and failed! Today, we will lift the core, clean it, and resolder the BGA chip - and then we hope for the best. To this day, nobody knows the frequency of this chip. Today we will get one last chance to reveal its secrets!

Disclaimer: I am not an expert when it comes to BGA rework, nor do I have the best equipment! But I try my best...
