My mac computer is a 400MHz PowerPC G4, is that possible to upgrade the MHz? If can, how can I do? Thanks.

More info is needed. If it is a PowerMac then you can most likely pull that processor out and put a new one in. Otherwise your luck may not be so great. There are some upgrades for other computer, but the PowerMac is the easiest to upgrade. So if it is a PowerMac, probably yes. If not, then maybe. But I don't think that you can overclock the processor that is in it, but someone else might be able to provide a better answer here.

Goto OWC (http://eshop.macsales.com/Accelerators/index.cfm) and select your model from the list on the right (below the blue bar), and you'll see what's available.

I would go here http://www.sonnettech.com/product/cpu_upgrades.html and check into some options. I upgraded my G3-400s to G4-800s and they are more than twice as fast. ;)

You should check on http://www.xlr8yourmac.com/ to see what otheers have done and recommend. Then i'd go to www.otherworldcomputing.com to purchase.

Well, your warranty is over, so you can also try to rearrange the jumpers next to the processor, that could give you an extra 50 mhz, and if you are lucky it will stay stable. There are threads about this at www.xlr8yourmac.com
Else get a new processor upgrade card from Sonnet or the likes.
