Next up we're going to take a look at the most important section of the BIOS, the MB Intelligent Tweaker. In this section, we'll be able to adjust everything needed to push our hardware to it's full potential. Our first option is something we don't usually see on motherboards. It is called M.I.T. Current Status, and it shows you the current status of your hardware. You'll be able to view information such as BCLK and QPI frequencies, as well as your multiplier and memory speeds.
The next section is titled Advanced Frequency Settings. You should be able to guess what you'll be able to adjust in this section, but just in case you can't, you'll be able to adjust settings needed to control hardware frequencies. Most of your overclocking will be done in this section. In it you'll be able to adjust the Multiplier, the BCLK, the QPI Clock Ratio, and a few other vital settings. Right under the Advanced Frequency settings are the Advanced Memory settings. Here you'll be able to adjust the memory multiplier and timings. Next up, we've got the advanced voltage control which, you guessed it, allows you to adjust voltages. Under voltage control is a section labeled Miscellaneous Settings you'll be able to enable Isochronous Support, and Virtualization Technology.
Now let's take a more detailed look at how we can adjust these settings. Right at the top of the list is the CPU multiplier. This can be adjusted by entering a number with your keypad. Under the multiplier is the Advanced CPU Core Features. This section isn't as important as the voltage and frequency controls, but it will prove to be an important section when overclocking. Here you'll be able to Enable Turbo Boost, C1E, EIST, the Thermal Monitor, and a few other features. You'll also have the ability to enable/disable CPU cores.
You won't be able to do much in terms of changing the QPI clock ratio. You'll have the choice of setting it at X32 or X36. Another feature that doesn't give you a whole lot of options is the BCLK Control. You'll be able to Enable/Disable the ability to adjust the BCLK, however, I'm sure most of the members here would leave it enabled. The next two settings up are the Extreme Memory Profile, and the System Memory Multiplier. The Extreme Memory Profile will allow you to select a memory profile, and the System Memory Multiplier will allow you to set the memory multiplier. Seems simple enough!
Like most boards, the P55A-UD4P and UD6 will let you set the PCI Frequency. You won't be able to manually enter the numbers, but rather select from a list. Some users may find the C.A.I.2 to come in handy. It will allow you to select from a few different profiles. After you've made your choice, it will "automatically adjust computing power to maximize performance". If what we've seen so far isn't enough tweaking for you, why not adjust the CPU and PCI Clock Drives? You will once again be able to select from a list of settings.
The last setting we'll be able to mess with in the Advanced Frequency Settings is the CPU Clock Skew. Once again you'll be able to select from a list of settings. Now let's get into the Advanced Memory Settings. Our first option up is the X.M.P. which you will be able to Enable or Disable. I find that I have more control of the memory when the X.M.P. is set to disabled, however, other users might enjoy using it. You'll find that you're once again given the option to adjust the System Memory Multiplier, but if you don't want to do that you could always set the performance to Standard, Turbo, or Extreme.
The last setting in the Advanced Memory Settings is the Selectable DRAM Timings. Your options will be AUTO, QUICK, or EXPERT. Now let's move on to the voltage control. Every setting in this section will allow you to select from a list of settings. The only exception to this is the Load Line Calibration, which can be enabled or disabled. The two Miscellaneous settings can also be disabled or enabled.
Now let's take a look at how these babies perform!
