Gigabyte’s Motherboard Intelligent Tweaker menu opens to reveal a few key status readings and a short list of submenus.
The Advanced Frequency Settings submenu might have otherwise been called a CPU menu, if not for the redundant memory multiplier setting. We reached a stable 4.66 GHz at our target 1.25 V. A submenu there reveals further CPU settings, including per-core and all-core multiplier options.
Setting Intel Turbo Boost technology to Disabled doesn’t completely disable it, but instead disables the CPU’s ability to manage its own clock speed in response to CPU load. This allowed us to more easily seek the maximum stable frequency for four-core loads without worrying about how much further the CPU would try to scale on its own in less demanding tasks.
The Advanced Memory Settings submenu contains the memory multiplier plus a few timing mode settings. Changing DRAM Timing Selectable from Auto enables the two Timing Settings submenus at the bottom of the page, where "Quick" links the timings of both channels and "Expert” enables per-channel timing settings.
An individual Auto option for each memory timing allows tuners to change only the timings they're familiar with. Setting an XMP profile on the previous menu causes each Auto timing to change from its original SPD to the corresponding XMP value.
Gigabyte’s Advanced Voltage Settings menu appears to be its biggest step toward inflating menu complexity. It merely contains three sub-submenu links.
Advanced Voltage Control is the one menu in Gigabyte’s UEFI structure with enough settings to justify its extra page. Of these, we found setting Vcore Loadline Calibration to High kept our CPU voltage stable under changing loads.
While CPU and DRAM voltage levels could have been incorporated into the CPU and DRAM settings menus, Gigabyte could have satisfied our drive for simplicity by at least combining these into one extra page rather than two. The Vcore setting is fairly accurate for low-load conditions, and Loadline Calibration can be used to keep voltage stable at higher CPU loads.
After experiencing some extremely good two-DIMM memory overclocks, we stuck a voltage meter on the board and found that the actual voltage is 0.03 V higher than both the settings and readings from the board. That is to say, setting 1.62 V got us our desired 1.65 V, even though both the firmware and Gigabyte’s monitoring utility reported 1.62 V.
