The BIOS on the ASRock 890GM Pro3 follows the same lines as all of the other ASRock boards we have tested. It is still an AMI BIOS format with the extra features common to ASRock products thrown in. As ASRock is still a subsidiary of ASUS, you will also notice that the BIOS is very similar to the way ASUS lays their BIOSes out.
Almost everything you need to worry about is on the OC Tweaker pages. Here are all of the options for kicking your AMD CPU into high gear. If you are into playing with the IGP, there are even options to adjust that as well.
There are one or two places to drill down and tweak additional performance settings. Like the memory timings for example.
But as with most BIOSes, you are not going to get away with just hitting up this area of the setup. There are more places to hit before you can get up and running. Places like the CPU configuration, Chipset Settings, etc.
The overclocking on the ASRock 890GM Pro 3 was not that great. We were able to push it some, but things got very touchy once we went over 242MHz on the bus. There was nothing we could do to get things stable. We even clocked the RAM down to an extremely low setting, but that did not help. In the end I would guess that the odd tracing layout hurts the system at those speeds. Most of the blue screen errors were memory related or related to Southbridge functions.

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.
