sosofm: Thank you for your response, but it is not answering what I put into my original follow up question. I do understand what you are saying, however. I just figured out how to copy the post I put into my original question. So, I am copying it here for you to review. It was written to furry_roadkill, but you can read it too. Again, thank you for your assistance.
furry_roadkill:
A quick follow up question: Given the fact that there are 7 PCIe slots on this MB and that select configurations of a graphics card or cards will utilize one or two slots and that there are headers (which I think are better named female connectors, but then I didn't name them) for the USB3_34 and ESATA, then what are the remaining five PCI slots for? Why do I need them?
For example, if I am using a PCIEX16 card in slot #7, using either the Auto or X1 mode then why would I want to put another PCIEX1 card in Slot #1? Furthermore, why would I want to use USB3_34 and ESATA cards (they do exist according to my local computer retail representatives), using the Auto mode? Or two additional PCIE1 cards in slots #1 and #3 and an ESATA card in some other available open slot?
All these questions come up because ASUS tech people put forth this chart in the manual.
Needless to say, furry_roadkill, you have been helpful. Thank you.
