I have a Pentium D 820 (poop I know) and a Intel branded 945P mobo lying around and might try building a "InMac" with it if I knew that OSX would see both cores as individual processors. I read in a HCL somewhere that Pentium D's show up as one core thats hyper-threaded. I'm also interested to know if any AMD X2 users out there have OSX running and showing their system as having 2 processors; anybody have any luck? I'd much rather go AMD dual-core than build on the Intel poop I have

On 10.4.3, a Pentium-D shows up properly, under 10.4.1 I had that weird way. Nothing wrong with that Pentium-D, either. It is a bit hot and not as fast in games, but 90% of people would never know.

Thanks for reply I'm glad that 10.4.3 properly identifies the two cores. You using sata hds? Know if the 945P chipset sata control is suported?
As a side note I got my Pent D 820 and Intel Branded 945P motherboard for $225 so I guess I shouldn't complain too much

Yes, SATA works just fine on ICH7. Not sure about RAID on ICH7-R though.

There are no RAID kexts for ICHs yet.
