Need some advice on upgrading a Sawtooth CPU...

So, I was looking around for a cheap upgrade CPU for a Sawtooth. I noticed that on Ebay there are many processors from later G4 models that are fairly cheap. After doing some searching, I realized that there seems to be a problem with the differences in bus speeds (Mine is 100 Mhz, Later models are 133 Mhz). Would this be a major issue in installing a CPU from a MDD or Quicksilver? If so, what can I do to fix it?

As far as I know, the MDD processors won't fit into a Sawtooth (they have separate upgrade processors as well). The Quicksilver processors may work fine, but you may just want to buy an aftermarket processor that you know will work.

Nopey dopey :)

Sawthooths have a ZIF-drop in cpu w/ a 100mhz bus, the Digital Audio & later models have a totally different, socketed cpu @133mhz or higher.

I used the DP/500 cpu card from a Gigabit Ethernet as a direct replacement for my old Sawtooth's SP/450 notta problemo....

No, sir, you are incorrect. Only the Yikes! had a zif, the Sawtooth and above all had daughtercards (Yikes!=ZIF and PCI graphics, Sawtooth=daughtercard and AGP graphics). The Sawtooth is, however, a 100mHz bus machine, so I don't think anything above that will work without some motherboard mods (which I think are possible). I could be wrong on that, though.

But going back to my original point, by the time you sort all that out, it's probably just cheaper to pick up an aftermarket upgrade (which are generally designed to operate on bus speeds at either 100 or 133mHz). I've seen the 1.0gHz upgrades go for under $75 on ebay.

Yep, my bad :p........I was thinkin of my beloved smurfbox at first..........but, you're right, the bus speed does limit the swap possibilities, but aftermarket upgrade cards are plentiful 4 sure :)
