Well, there is two issues...

1: The PLL settings will have to be changed if the processor came with an MDD with a 167MHz bus, as the DA has a 133MHz bus. So the processor will run slower in the DA without a change.

2: You need to supply 12VDC to the 4th leg on the CPU module, otherwise the machine will not boot.

Problems...

Submitted by KeithNDSU on January 19, 2005 - 1:38am.

1. The MDD proc will not physically fit in anything besides a MDD or XServe.

2. See #1, Stuka is thinking of a quicksilver proc.

hmm, could have sworn the MDD

hmm, could have sworn the MDD needed a 12VDC feed as well. I didnt think of the card size itself.

I'd be curious for a final ruling on this issue. Is it simply the size of the card that is a problem? I thought the connector was different, too. That would be great for me if it was just a size issue since I planned on using it in a different case.

Size Issue

Submitted by KeithNDSU on January 20, 2005 - 4:15pm.

It isn't a case size issue, one of the RAM DIMM connectors is in the way as I recall. I don't have both pieces to check, but that is what superdork Tycho originally stated when he had MDD parts for sale and pictures agree.

doubt it's possible

Submitted by dankephoto on January 20, 2005 - 7:02pm.

I scoped out putting an MDD CPU into my QS. While the connector is the same for QS and MDD, it's a no go as the MDD CPU would overhang the ram . . . or the AGP slot . . . or something, I forget the exact problem just now, I'd look up the earlier AF thread but I'm too lazy.

However, it appears a more serious problem is that the earlier AGP G4s are based on the UniNorth chipset and the MDD is not. (Do I have that right?) Puzzled

It seems unlikely one could ever get past that lil' issue.
