I bought a Celeron 566 supposed to be guaranteed to run at 850 but I never could get it to run stable on BE6 II and Iwill Slocket II no matter the voltage. I then bought a PIII 800 fcpga and installed it into the Iwill slocket and Abit BE6-II. At default voltage I still can't get this to run stable. All the jumpers are set to auto and set to FC-ppg on the slocket. I was wondering if some of these pentium III chips require higher than default voltage or is there a problem with the slocket or compatability problem with the Iwill slocket and the Abit BE6 II.
