AMD FX8350 BE / Gigabyte HD7970 / ASUS Sabertooth 990FX R2 Review

The ASUS UEFI Bios is fantastic, defaulting to the basic mode for inexperienced users. This mode allows for easy adjustments to basic settings, such as dragging drives into position. The rest of this page will focus on the advanced panels however.

The Main interface tab which gives an overview of the system. We have 8GB of memory running at 1,600mhz. We updated the BIOS to the latest version for this review – ASUS supplied this just before testing commenced.

The AI Tweaker panel, which is used for overclocking and adjusting the settings. We will look at this in more detail shortly.

The Advanced panel allows control over various motherboard settings, including North Bridge and South Bridge.

The Monitor panel highlights component temperatures, voltages and fan speeds.

If you have multiple drives installed then the Boot menu is very important as you can tailor boot priority here.

The Tool menu can be used to flash the BIOS, as well as loading and saving various profiles.

System validation at default speeds is available here.

To overclock, we used the AI Overclock Tuner menu and selected the D.O.C.P option. We are using 2,133mhz Patriot memory so we know we wont have a problem pushing the CPU bus frequency higher without forcing speeds down.

At 228 bus frequency, the AMD FX8350 was running at 4.4ghz. We had no problems at this speed and decided to push a little harder. It is worth bearing in mind that we didn’t have time to reinstall with a high end cooler for this section of the review, so we used a £16 Arctic Cooling Freezer 7 Pro Rev. 2 – available from Amazon over here. We like using these coolers, as they are easy to fit, quiet and very inexpensive considering their decent capabilities.

We increased the CPU Ratio to x20, at 228 CPU Bus Frequency, translating to a 4,600mhz clock speed. The System was perfectly stable at these settings.

Any higher than 4.6ghz with this cheap cooler and the system would become unstable, but we are positive that 4.8ghz+ would be possible with high end coolers.

CPU validation at 4.6ghz is available over here.
