F7 or F6? GA-Z68X-UD5-B3

In the DSDT Database, GA-Z68X-UD5-B3 is designated as F7 or F6. How can I tell which one I have? I just purchased the Gigabyte motherboard but I don't know what F7 and F6 mean.

Thanks

F6 or F7 refers to the BIOS revision you are using. When you boot it should show up briefly, but you should also be able to find the information by entering your BIOS (not at my hack right now, so can't check specifically where the info is at).
If it shows something else, ie. F4 or something, you need to flash your BIOS with a new version - get it at the Gigabyte website

Hope this helps
