Thanks for the additional info
Try DriverMax and see if it suggests any alternative drivers http://www.innovativ....com/drivermax/
Please ensure that if you had any other drivers installed for the card that they were completely uninstalled before installing the newer drivers, you must also do the same with any drivers that DriverMax may suggest or you will end up with the drivers conflicting and causing display issues - also avoid using beta drivers at all costs.I am only suggesting the free driver downloads and in no way suggesting that you use any other product or service at the link.
For removing any earlier drivers http://www.revounins...e_download.html
I note one small difference in the Ram details that you have provided which is F3-10666CL9S-8GBXL, this Ram is not on the MBs QVL (see below) but this model is F3-10666CL9D-8GBXL, the difference being CL9S and CL9D.
For the best and most stable performance you should where possible purchase a CPU and Ram that have been tested and approved by the motherboard manufacturer, this is referred to as the QVL ( qualified vendors list ) understand though that there are too many products released for them all to be tested so other hardware will be compatible but not proven to be.
Your MBs QVL, see the Memory Support List to the upper left http://www.asrock.co...8 Extreme3 Gen3
Do not worry about the Ram at present as it is most likely ok with your board and this is a driver issue.
Where your video card slot is concerned as nothing is specified you have acted correctly, the slots are PCI-E 3.0 capable but also backwards compatible and should not cause this.
Let us know how you get on with the above but if needs be there is other Free system testing software available for you.
