Found some info.
My board has a CY2220-PVC-1 PLL
As for the Supermicro I860 boards I don't know any way to set the FSB to 533Mhz either through normal means. However, my P4DC6 (and I assume the P4DCE, P4DCE+, and P4DC6+) use the Cypress CY 2220 PVC-1 clock generator chip. According to it's datasheet, it is capable of a 133Mhz CPU clock. According to the datasheet the way to set the CPU clock to 133Mhz is by pulling sel133, which is pin 23 on the CY 2220, high. So, in theory if you connected this pin to +3.3v your board should run at 533Mhz FSB. Of course that would require cutting the pins existing connection (as it may be grounded at 100Mhz cpu clock) and soldering a jumper from it to +3.3v or one of the other pins on the chip that is already +3.3v. Keeping in mind that the pins are very small and delicate and these boards cost a bit more than your average board, most people are unwilling to try such a modification to a board like this but for someone who's brave enough and can afford to take the risk it might be worth a try.
This would be nuts!. I could try it....but it would be very hard.
BTW, for ****s and giggles
This was the temp during that run...ran it fanless...hahahaEdited by Slappa - 12/13/11 at 12:25am
