The Motherboard Intelligent Tweaker section of the BIOS is where you can do all of your performance management. Setting clock speeds, multipliers, and memory timings - it's all here. Gigabyte has delivered an easy to use overclocking section of the BIOS that gives you the tools to reach your overclocking goals. The MIT section on the GA-P55-UD3R is exactly like that used by the top-of-the-line UD6, so if this looks familiar there is a reason. Once you open the M.I.T. section, you are greeted with a total of five submenus to work with, as well as top level information on what the current clock speeds, temperatures, and voltages are. By choosing the MIT current status tab, the information is more granular! Under this tab, you have the ability to view, but not change, any of the information that is presented.
The Advanced Frequency Setting tab is the part of the BIOS where you set the bclock, QPI clock, CPU bclock multiplier, view the memory multiplier and speed, PCIE clock, and work with the advanced CPU features. The maximum CPU clock and memory multipliers are going to be limited by the CPU you choose to use in the board. Even so, memory speeds above 2000MHz are even achievable with the i5 750! Under the Advanced CPU Core Features tab, you are able to enable or disable all of the Intel CPU performance and economy options, such as Turbo Boost technology, EIST, Multi Threading (If using an 8 series i7), C1E, as well as enabling all or some of the cores. The bclock setting is adjustable from 100-1200, not that it will go that high, but the adjustment is there. XMP memory profiles are supported for modules that carry this certification so that setting the memory up is simple, since all the back end work has been done. Th PCIe frequency can be adjusted for more graphics performance and has a limit of 150MHz. This setting helps with an increased bclock but is best used sparingly.
Tweaking the memory is done under the Advanced Memory Settings tab. The first option you have is to enable or disable the X.M.P. profile. The second option allows you to set the memory multiplier, but this is limited to the options available with your CPU. Performance Enhance has three levels that you can set with varying effects on performance. Extreme being the highest. This usually involves setting the memory sub timings a bit tighter to increase performance, at the cost of stability. One item that is quite a bit different than other manufacturers BIOS' is the ability to change the memory sub timings by memory channel instead of having a global setting to change both channels.
Under the Advanced Voltage Settings tab you get the pleasure of tweaking the voltages to get the most clock speed you can get from your hardware. Load Line calibration offsets the voltage droop Intel has specified, to try and keep the voltage closer to what you set manually. There are three levels to choose from: Standard, Level 1, and Level 2. Voltages that can be tuned include Vcore, QPI/VTT, PCH Core, CPU PLL, DRAM, DRAM Termination, and the reference voltages by channel.
The Miscellaneous Settings tab only has two options that can be either enabled or disabled, Isochronous Support and Virtualization Technology.
