The K8V-X BIOS is loaded with plethora of tweaks that you are accustomed to from tier-one companies. The ability to tweak the system bus and sufficient voltage settings are also present in various degrees. The CPU voltage of up to 1.450v is more than enough to satisfy even the most die-hard overclocker. Considering that Athlon 64 microprocessors are considerably cooler than Intel’s Prescott chips and KT800 chipset have limited overclocking features, the CPU voltage doesn’t even come into play majority of the time. Of course there are instances when you need to push the voltage a little bit to stabilize the system even at mediocre overclocks around 225Mhz or less.

Asus has kindly provided the AGP and V-Link voltages as well for truly pushing the system forward, however, there are two major problems that plague this board. The first one, clearly, is the lack of AGP/PCI lock on the K8V-X. Even though you can increase the voltage on the AGP voltage, it won’t help when you are really trying to move ahead with overclocking. In today’s times, an AGP/PCI lock is a must. The second issue is the lack of high-end memory voltages. A maximum offering of 2.8v just isn’t enough to push the board to its limits. This is especially the case with the latest TCCD, low-latency chips that require a recommended voltage of 2.75v to operate, but we have found them to run perfectly fine at 2.65v as well, so they may or may not cause issues.

Although the BIOS offers superb tweaking options, the board is hindered due to the lack of features for even the slightly interested overclocker. That being said, you will be able to alter and improve the performance of the board at stock settings. The BIOS is a mixed bag of treats at best.
