Question about SuperMicro X7DAL-E Motherboard
Is there a problem with the PCI-Express interfaces on this board that would casue the computer to crash when I perform a particlar action on one of my PCI-Express cards
The problem is not the board, it is the implementation and the limit of the PCI-e lanes in the CPU.
Solution, Do not use slot 4.
For add in cards use old PCI-X cards at 133MHz.
They are cheap used, 64 bit, and are 8 times faster than PCI.

Yeah, but it's not the slot; it's the northbridge chipset or a PCI bridge driving it that's perhaps overheated or set funny. If you use 2 CPUs they can fall out of step several ways, or your clock circuits can age badly by themselves! Got fresh CMOS batteries in there? It could be that PCIe was merely asked to run at a frequency it won't run. You should carefully make sure the board is nice and clean, reflash or at least clear settings on the BIOS, confirm the PCI videocard boots, make sure all the chips are cooled well, and again see if you can get a PCIe card to work without complaint.

No. There is no software to change pci-e speeds. You would need a board already set up for pci-e2 to get the top speeds. Most pci-e2 graphics cards are backwards compatible but they will run at the slower speed. Hope this helps.
