The Q-Flash utility seems to be the only feature making the work with Gigabyte GA-P35-DS3R mainboard easier. Other innovations introduced in the BIOS Setup are quite arguable, in my opinion. One of the most frustrating one is the fact that some important memory controller configuration settings are “hidden” in the BIOS Setup. You can see these settings and get access to them only by pressing a “secret combination” of keys in the main menu of BIOS Setup. The combination is Ctrl+F1, but unfortunately, there is no mention of it anywhere, even in the mainboard user’s manual.
