An excellent page on compatibility of G4 CPU modules between different models.

 

From theos911's post here.

Hello Bunsen....

 

Would the above link include Zif socket G4 CPUs like one might find in the Yikes! motherboard?

If not, do you know of a URL that covers this odd ball CPU?

Thanks

Are Quicksilvers really restricted to just Quicksilver CPU modules and rare and obscenely expensive 3rd party upgrades? That's unfortunate, I'd like dual CPUs or a faster single in my QS'02 but 933MHz is the fastest single and the 1GHz dual module is pretty hard to find...

I know it’s been nearly a year since this question was posed without a reply, but since I bought my own single-CPU Quicksilver G4 today (800MHz) I’m really curious about what my options are for CPU upgrades. Does anyone have a good answer to this one?

It would be really great if it were possible to stick an MDD processor into a QS. I've read that it doesn't work, but I'm not sure why: bus-speed incompatibility (133MHz vs 166MHz), physical incompatibility (processor & heatsink is simply the wrong shape), pin/processor incompatibility (this shouldn't be, they both PPC 7455s).

I am also a big fan of Arctic Cooling, now upgraded to MX4.  I have used it in rebuilding laptops, Macs and PCs.  For novice users, the big problem is that they use far too much.  Follow the directions!  Thank you for the post Bunsen.

It's not bus speed as they made a couple of MDD models with 133 mhz bus speed. If it was otherwise hardware compatible then some of the aftermarket suppliers would have made their cpu upgrades for all G4s

Physically fitting is one thing, working is another. The MDD has been out for over 15 years and in that time I haven't seen a single person demonstrate a MDD processor in anything else.

The opposite also. All those processor upgrades for the QS, DA and so forth and none of those work in the MDD. I'd love it if I could move the 1.8ghz module from my DA to my MDD.

Well, aren't MDD processors interchangeable with the Xserve?

 

I see your point, though; the Xserve-MDD swap works because the Xserve is basically an MDD in 1U rack-mount form, so it doesn't really count.
