ASRock's BIOS is very similar is design and layout to the ASUS BIOS setups. After seeing the main screen you are greeted with when first entering the BIOS, you may think you actually do have an ASUS board. This BIOS has been used for quite some time and is pretty easy to navigate around.
The bulk of the overclocking features are located under the OC Tweaker menu. It is here you can adjust the CPU FSB, memory ratios, HT Link dividers and widths, integrated AMD Northbridge clock ratios, voltages as well as the clocks for the IGP and the Sideport memory speed.
There are a few more features to tweak under the CPU Configuration and the Chipset Configuration menu however not alot compared to the OC Tweaker area.
Our overclocking adventures weren't as good as we hoped. Using our 965 based CPU we only managed to get 220 MHz FSB out of the board. It didn't matter if we lowered the CPU ratio or not, this board would not run past 220 MHz FSB.
You can see the validation here.
As all overclocking results are dependent on the hardware you use your results may vary. Results of our overclocking tests are included in the performance section with the stock scores.
Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.
