Question about one option in Sabertooth Z77 Bios

Thread Starter 
I've got a question regarding the PCIe Express x16_3 (black) bandwidth setting in UEFI.

I can run it in x1 mode or x4 mode. It's default to x1.

At x4 mode the PCIe x16_3 the PCIe_3 slot runs x4 mode for high performance support. PCIe_1, PCIe_2, PCIe_3 are disabled.

At x1 mode the PCIe)_3 run at x1 mode with all slots enabled.

If I've only got the one dual GPU card which setting is best for me to run it at?



What will be if i change to 4x?

Unless you're doing tri-SLi, you don't really want to be using that slot unless you have too.
