However, the ordinary appearance of the Gigabyte 890GPA-UD3H conceals advanced software tools that can be used to overclock the CPU and fine-tine system performance. Most of them can be found on the MB Intelligent Tweaker page of the BIOS Setup.
Like any Socket AM3 platform for enthusiasts, the Gigabyte 890GPA-UD3H offers all the options for controlling the clock generator's frequency and the accompanying multipliers (of the frequencies of the CPU, CPU-integrated North Bridge, HyperTransport bus and system memory). It is handy that when you change any of these values, the mainboard shows you what resulting frequencies of the different system components you are going to have.
Voltage tweaking is just as good here. You can change the voltage on the CPU and its North Bridge, on the memory chips, on the AMD 890GX chip and on the Sideport Memory. The CPU voltages are set as relative rather than absolute values, so all the power-saving technologies keep on working even when the system is overclocked. By the way, the settings are all accompanied by information fields that show the current values of the voltages to make it simpler to see the big picture for the whole computer.
Despite the lack of any BIOS option to counteract a voltage drop under load, this effect does not show up on the Gigabyte 890GPA-UD3H because the power circuit of this mainboard is governed by a new linear feedback scheme that adjusts the voltages automatically. Thanks to it, the voltages do not fluctuate much under different loads.
Memory latency parameters can be found on a separate page. You get a full selection of adjustable timings here while the information about recommended values shown nearby makes it easier to manually configure the memory subsystem.
There is a special BIOS page for overclocking the integrated graphics core. You can change the clock rate of the Radeon HD 4290 as well as of the Sideport memory.
CPU technologies can be accessed through the Advanced BIOS Features page. Unfortunately, you can only enable Cool'n'Quiet and virtualization technologies here. The Gigabyte 890GPA-UD3H cannot unlock disabled CPU cores like the ASUS mainboard.
The hardware monitoring section of the Gigabyte mainboard is inferior to that of the ASUS M4A89GTD PRO/USB3. There are no options to control the CPU cooler and system fans here.
Well, the lack of such options in the BIOS of the Gigabyte 890GPA-UD3H is made up for by Windows-based utilities. Gigabyte's handy and functional EasyTune 6 tool is included with the mainboard for that.
This utility can overclock the CPU and graphics core from Windows and offers extensive hardware monitoring options. You can also use it to set up the operation of the CPU cooler.
