Powermac digital audio upgrade to 1ghz?

A few years ago I upgraded a 466 DA with a 1 GHz Sonnet card. IIRC, it was a very strait-forward job with no complications. The upgrade was well worth doing, the difference in speed being very impressive. I don't believe I even had to patch the firmware.

It is a very good idea, however, to read the instructions for your particular upgrade card and to ensure that you use the correct tools for the job, especially where it comes to cross-point screwdrivers. The manual should be downloadable from the manufacturer's web site.

A useful resource for these sorts of projects is the CPU database at XLR8yourmac.com. It's full of actual user reports as to what fits what.

Then it's not gonna work. Different CPUs using different sockets.

You need something for a DA or Quicksilver. Using MDD parts will not work. And no, there is no way to make it work.

I don't know. You really need to check the database that I linked to in my previous post. If it's going to work, you'll probably need the 12 V mod as detailed here.

Re MikeL's post. It could be from a FW800 MDD model but it could also be from an earlier quicksilver. If it's from an MDD, you can forget it. If it was from a quicksilver, you should be golden! I'd say it's worth pulling your original chip to compare connectors.

It's not going to work. It's that simple.
