Running BOINC Milkyway project it shows at 3.0.


One thing I'd mention is this is my first build and I have't done any tweaking/OCing yet. I did run the new OC Scanner utility on the cards, but that's it. As you noticed I'm also on V1.20 of the board BIOS. I'm probably as close to "fresh out of box" as I could be.

To run pci-e in 3.0 mode or 16x, you must connect molex power to the board located on bottom. Sorry for my bad english. with out it I can run only 2.0 or 1.1 standard, bios is beta 1.31

Thanks, that actually would not make any difference connecting the molex or not in this case. I did however fix the issue anyway by once again re-seating the card.

PCI-e can go into power-saving mode and lower its "displayed" active mode within an OS can therefore vary from x16 to x8 or x4 depending on system load so sometimes when you initialize a hardware monitoring piece of software it may be inaccurate at displaying whats actually going on since it only has direct access to the firmware to read certain sensors and information off of your device on launch. Not every attribute listed is real-time in displaying updated information accurately, especially on pci-e video cards that are always adjusting clock-speed and power draw based on usage%.

If you're worried about lost potential performance then I would get a different board with dedicated PLX chips for true x16 to every slot without digital interpolating of electron traffic when multiple slots are occupied. Very few boards actually run x16 24/7 on more than one slot at a time, especially on an AMD.
