As for the BIOS Setup of our ASUS K8N-DL, it is very similar to the BIOS Setup of many other ASUS mainboards, even though the features list is different in our case. Among these differences I would like to specifically point out the memory subsystem configuring options in the first place.

Among the common frequency and latency settings of the on-die memory controller, there are quite a few ECC configuration options.

Other than that the BIOS Setup of ASUS K8N-DL features pretty common settings.

Hardware monitoring implemented in ASUS K8N-DL mainboard doesn’t boast anything outstanding. Its only remarkable peculiarity is the ability to monitor and control the temperature and fan rotation speed for each CPU independently. They also offer special Q-Fan technology that allows adjusting both CPU fan rotation speeds depending on the CPU temperature.

The BIOS Setup also offers a few overclocking friendly options. First, the mainboard allows changing the clock generator frequency from the nominal 200MHz up to 400MHz with 1MHz increment.

Also, the mainboard allows adjusting numerous voltages.

The memory voltage can be increased up to 2.9V (with 0.1V increment), the chipset voltage can be raised from the nominal 1.5V to 1.8V with 0.1V increment, the HyperTransport voltage can also be raised above the nominal 1.2V to 1.35V with 0.05V increment. As for the processors core voltage, the choice is quite limited. The BIOS Setup only allows either setting the nominal Vcore value or raising it by 50mV.

However, the mere fact that this dual-processor workstation platform offers any overclocking friendly features at all it already very valuable. Although we couldn’t really enjoy all this overclocking fun to the full extent. The thing is that we only had the top dual-core Opteron processor models at our disposal that worked at 2.2GHz nominal frequency. Since ASUS K8N-DL doesn’t allow reducing the CPU clock frequency multiplier, the overclocking is limited by the processor potential in our case. The best we managed to achieve without losing the system stability was the 212MHz clock generator frequency. The CPUs worked at 2.33GHz in this case. However, even this relatively modest result indicates that ASUS K8N-DL is suitable for overclocking. So, it can turn into a very attractive platform when used with younger AMD Opteron models with relatively low clock rates.
