Successful upgrade

First of all I apologize for not posting in the forum.

The upgrade went successful from a Celeron 700Mhz to the above PIII chip. Of course it is recognized as 750Mhz because it's running at 100 FSB instead of 133. I could overclock but is this really wise when using the old heat sink and case fan?

I am planning to upgrade to the chip above(SL52R) from my Celeron 700MHZ. Its on a HP Pavilion XG823. Everything seems to match up can someone tell if this will work?

Response: Plase post upgrade questions in the forum.

Here is my Pentium III runing at 1.3GHz with homemade watercooling, the CPU stays in 30C, the bad part is that the onboard sound, vide, ethernet are not working at this FSB so I'm using a PCI sound, and network cards

My CPU looks like this, is there any diference?

Diferent look

Response: Your CPU has 1.75V core voltage, higher maximum operating temperature and higher power dissipation than the pictured one.
