I've recently acquired a Pentium MMX 233 chip in very good operational and aesthetic condition, for the bank-breaking price of $2.50. I thought I might try experimenting with overclocking of this CPU... I have a K6-2 400, so I'm not doing this just to get raw speed, moreso as an experiment. Everyone on this forum seems keen on overclocking AMD chips, but not so much mention of overclocking Intel chips. I've read elsewhere that overclocking MMX chips is entirely feasible with good success.
My initial plan is to simply change the FSB speed from 66Mhz to 75Mhz, keeping the 3.5 multiplier (which should get it to 262Mhz), maybe upping the voltage from 2.8V to 2.9V. And before anyone freaks out, the motherboard has a jumper for PCI clock speed ratio, so it can be set to either 1/2 (66/2 = 33) or to 2/5 (75*2/5 = 30, or 83*2/5 = 33) so no worries about overclocking the PCI bus. My concern, however, is that this particular CPU package has Intel's stock heatsink and fan epoxyed to the chip, and I'm not sure I'm comfortable enough to attempt removing it.
Thoughts? Has anyone else tried to overclock their MMX? Is this a bad idea? I think if I were to have and be able to use a heavier duty heatsink and fan I might just say screw it and go for it, but alas...
