Subject: fw800 dual 1.42 Processor card in a non- fw800 MDD?

Can I install a dual 1.42 Processor card that came out of a MDD FW800
onto a non-FW800 logic board? inside a non-FW800 MDD Powermac? Jeff
Yes, you just have to match the system bus speed.

I had a Dual-1.0 GHz MDD (original, non-FireWire-800), which has a
167 MHz
system bus and now it's running a Dual-1.42 GHz (out of a FW800)
without any
problems -- and without the need of modifications aside from the
processor
card swap.
The only importaint thing is to use the correct heat sink, because
the one
from the Dual-1.0 GHz doesn't have the capacity to offload enough
heat, so you
definitely need the one from the Dual-1.42 GHz out of the FW800 it
came with.
Cheers,
Andreas
I did the exact same thing. I managed to score a dual 1.42 GHz card
and heat sink for what was a single 1.25 GHz machine. All I did was
swap out the old, and install the new. Worked without issues the
very first time. Although, even with the correct heatsink, the fans do
run louder, but I've gotten used to it, so it doesn't bother much
anymore. And I don't know if the dual card came from a FW800 or FW400
box. I was just glad I had the 167 MHz bus speed so I didn't have to
mess with that.
And while I had the machine open, I cleaned it out, carefully, and
swapped one of the installed 120 GB HDD's for a 250GB drive and
(finally) upgraded to Leopard. I debated the worth of doing any
upgrading on a four year old {{C machine, but it has served me well,
and my current uses don't demand an Intel box, yet.
