I was looking at my specs, I have mobos that have 16x pcie same with a video cards .
4770k Expansion Options
PCI Express Revision 3.0
PCI Express Configurations ‡ Up to 1x16, 2x8, 1x8/2x4
Max # of PCI Express Lanes 16
This processor has pci express 4x4
Intel® Xeon® Processor X5450
(12M Cache, 3.00 GHz, 1333 MHz FSB)
When I was looking at xeon processors and some other old ones it does not have specs for the Expansion Options how do I know the cpu can do the full 16x speeds and would the X5450 just run 4x speed even if it was on a 16x mobo and how can I see those specs if not listed for I can tell if the process can do 4x or 8x or 16x at 1.0 or 2.0 or 3.0 revision.
