I have an older Compaq Presario 4505, I recently upgraded the Pentium 166mmx cpu with an OEM Pentium 233mmx. This is the fastest chip my motherboard will support. A friend of mine said I could overclock the new 233mhz cpu to 266mhz. Is this true? If there are no adverse consequences in overclocking, any tips on how to do it would be appreciated.
