I.E. would you be likely to be able to >successfully raise 33mhz to 40 mhz, and with a DX2-66 have 80mhz internally? Very doubtful. Remember, when you're pushing a 33 to 40 you're pushing a chip that was actually designed to run at 50 Mhz but this particular part didn't make the cut (at 50). The real question to ask would be... "Has anyone successfully pushed a DX50? And to what speed. Of course the inherent problems with this scheme is that most motherboards are only designed to run at a maximum of 50 Mhz so it would be difficult to tell if the CPU is failing or if the motherboard is inducing the failure. Be sure to change the bus clock speed divider when pushing the CPU speed or you may notice a failure due to the increased speed of peripheral cards. -Carl- --
