Per the title, my new ASRock Z77 Extreme 4 is not detecting a new Sapphire 7850 in PCIE 3.0 x16. It will not find the card at all in the top PCIE x16 3.0 port unless I manually set the card to Gen1. It will detect the card in the bottom PCIE 3.0 x16 port in Auto, but according to GPU-Z the card only runs in x8 3.0.

This looks similar to an issue on these boards here: http://forums.tweaktown.com/asrock/4...850-gpu-2.html
However, the card tested there looks different from my card in GPU-Z: http://download.asrock.com/Z77%20Ext...e%20HD7850.jpg
Specifically, different clock and memory, and different bios and Catalyst versions. My card's SKU is 11200-07-20G.
I am just trying to determine if it's a Sapphire card problem (already submitted a ticket, no response), an ASRock z77 extreme 4 issue, or if there's something I can do to try to fix this problem--ideally sooner rather than later in case I need to RMA or return a part within a certain period.
Thanks for any help you all can offer.
For parts, I'm using:
ASrock z77 Extreme 4
8 GB RAM
Sapphire 7850 2GB GDDR5
1TB Barracuda HD
i5 3570k (not overclocked)
750W Silencer MK2
