Hi all, first of all, I know this question was addressed a while back, but I can't find it in a search (the search engine on this site is awful). Anyway, here goes. I'm ready to buy a refurb dual 1.8 (after MWSF...but I'm not holding my breath about new g5's), and I have a major concern. PCI vs PCI-X. I don't care about the speed of the bus or whatever....it's just that there seems to be a lot of misinformation about the standard and compatibility specs on the internet and I thought maybe I could get a definitive answer here. I've already had to sell my g4 desktop and digi 001 because of PCI compatibility issues with the g5's. As I understand it, the voltage is different. If I buy a new dual 1.8, will most future PCI-X cards be incompatible with the PCI on the DP 1.8? If it's just a regular PCI slot, why couldn't my digidesign PCI card work with it? The only thing I can think of is that it may be a higher voltage PCI slot and thus NOT a normal PCI slot but also NOT pci-x???? I am looking into buying a lynx 2 mastering converter PCI interface soon. Assuming it works with the dual 2.0 and 2.5 (I know it does), will it work with the dual 1.8? sorry for the confusion.... Thanks for the reply and if someone is an archive digger and has found a prior thread discussing this topic, please point me to it.
