Re: PCI question

These are 64bit PCI slots, not PCI-X, there is a huge difference. There was an early G5 PowerMac that had PCI-X slots but no G4 ever did. > > Picture of a G4 MDD showing the PCI-X slots on the left hand side: > > http://guide-images.ifixit.**net/igi/YU2gIgVCdH1L3hSa

Re: PCI question

I ran into this recently trying to get a ppc G5 MOTU audio card. even with a long detailed conversation on teh phone with a MOTu tech advisor, we STILL got teh wrong card shipped to me. PCI-X - its fully backwards compatible with regular PCI, but can operate at 64bit and 66mhz or higher

According to this from Apple, no G4 has PCI-X: http://support.apple.com/kb/ht3082 From: Valter Prahlad To: g3-5-list@googlegroups.com Sent: Wednesday, November 16, 2011 11:45 AM Subject: Re: PCI question Il giorno 16-11-2011 18:41, Brielle Bruns ha scritto
