The 366@550 is running on an old BH6 rev 1.03. It has been a great processor, this is it's third home, and it
always overclocked to 100Mhz FSB at default voltage. Steady as a rock. This just went into a system I threw
together for my brother out of odds and ends I had laying about.
The 900 celeron is on a BX6-Rev2. It's running only slightly overclocked, FSB is 106. The processor
was about $50 at newegg, and with a $5 slocket, I went way up on speed for little dinero.
This box used to have the 366@550 in it. Not sure how this slocket does FCPGA, as there
is no jumper to differentiate between PPGA and FCPGA, but it worked both ways.
