BIOS Setup

Gigabyte GA-EP45T-Extreme mainboard uses BIOS based on Award Software code that Gigabyte engineers have seriously modified and adapted for their products. Some differences can already be noticed in the very first screen. For example, “MB Intelligent Tweaker (M.I.T.)” section containing almost all the settings for computer enthusiasts and overclocking fans is now the first in the list:

This is a totally right thing to do! A regular user accesses the mainboard BIOS only once during the initial configuration process. He or she may have to get there once again to make a few changes and corrections and that’s about it. And when you overclock, you have to access the BIOS over and over again, often on every system reboot, and having the right section on top of the list is definitely great help. A small thing, a little improvement, right? Yes, it is. But contemporary mainboards often offer similar functionality and a combination of several small advantages like that may distinguish a good board from a not very good one and turn a good board into an excellent solution.

“MB Intelligent Tweaker (M.I.T.)” section turned out simply gigantic, you will have to go through at least three screens to see everything it has to offer. However, the user is very unlikely to get lost in there, because it has very well thought-through structure. All parameters are split into groups referring to CPU, chipset, memory and voltages. They used several different colors to make navigation more illustrative, introduced context help and a number of informational parameters, so using “MB Intelligent Tweaker (M.I.T.)” section is very easy and convenient.

I don’t think I need to tell you about each and every parameter. Let me just point out a few peculiarities. For example, note that some parameters dealing with chipset fine tuning are singled out into “Advanced Clock Control” subsection.

The memory frequency is set with multipliers. The letter will indicate what bus frequency this multiplier refers to and context help in the right-hand side of the window will break down the terms for you. You won’t need to calculate the resulting memory frequency, as the informational “Memory Frequency” parameter will display it for you. It is very convenient that the “Memory Frequency” value will change once the bus frequency changes, i.e. you will always know the actual memory frequency.

You can correct the main memory timings if necessary. If this is not enough and you need to access additional timings, you have to open a large nested sub-menu called “Advanced Timing Control”:

Here we can configure a number of general purpose timings and in the next sub-menu we can set individual parameters independently for each memory channel. Among them are a very important parameter called “Performance Level” that can be set directly using “Static tRead Value” setting:
