Made the upgrade from the GTX 680 to the K20c, and I see that PCI-E 3.0 is not supported by this card? I installed the driver and it sees that card, but maybe something still is not configured correctly? I did download and install the driver.
My bandwidth speed test is half of what is was with the 680, and am surprised that it wants to use PCI-E 2.0 when I have been using PCI-E 3.0 with the 680. Both cards are installed but for calculations it wants to use the K20 (device 0) which is running at a much lower speed than the 680
I really had things configured perfectly with the 680… Is there any resource out there which at least get this to a similar performance level?
Operating system is Windows 7 64 bit, and the motherboard supports PCI-E 3.0, which still works for the 680 alone.
