CPU Upgrade Compatibility?

[sambapati87]

I'm possibly interested in upgrading the CPU in my Sawtooth (500mhz now).

I don't want to buy one of the 3rd party upgrade cards -- I'd prefer to buy a stock CPU that was pulled when it's original machine was upgraded or parted out for price reasons.

My question is, since the Sawtooths max'ed out at 500mhz (from what I can tell), which processors from the newer models of PowerMac G4s can I use?

Thanks

the main problem you have with a sawtooth and dual CPUs is that most of the boards don't support Dual CPUs. If you have a revision newer than Rev 3, you can do it. I am hoping the Sawtooth I have coming can do it. I already bought a Dual 450 CPU Module and I hope it will work :-S

Anyways, there is a simple way to

Thanks for the link -- I guess what I'm really asking is:

Can I put this

In a Sawtooth?

I have the same question and for the same reasons, but mine is 400mhz.

The Quicksilver uses a 133mhz bus, the Sawtooth only uses a 100mhz one. The Quicksilver 800 CPU would have a multiplier of 6, so it would only run at 600mhz on a Sawtooth, if it worked at all. You would also need to be able to run an additional power line to the Quicksilver CPU because it normally draws power from one of the posts it rests on in the Quicksilver case which isn't in the earlier models. Sometimes you can find overclocked CPU's on ebay if you think you can trust that sort of thing. If you really need a faster CPU, though, and your motherboard supports it, go for a dual 450 or 500. They are dirt cheap. Otherwise you can save for a faster aftermarket CPU upgrade, which might be a good idea to do since they seem to be drying up.

This Q is quite FA around here. Perhaps we need a FAQ page.

My short answer is go to xlr8yourmac.com under articles->systems->g4 from their front page navigation bar

Wow. I hate it when the thread I'm asking a question on is in the top 5 google results when I search for info on my question.
