The CPU voltage regulator located right behind the Socket754 is designed according to a widely spread three-channel scheme. The processor Vcore is not increased, the temperature monitoring system used the thermal diode integrated into the processor. Here we should definitely give credit to Leadtek engineers: Leadtek K8N Pro supports Cool’n’Quiet technology, which allows to reduce the heat dissipation and CPU power consumption really significantly.

BIOS Setup of this mainboard is based on Award code. Note that it is organized in a bit unusual way, which differs from what we usually see. In a few cases it even strikes as somewhat illogical, however, no options are missing in the BIOS Setup. For memory settings configuration BIOS Setup of Leadtek K8N Pro offers the opportunity to fine-tune major memory timings and adjust the memory bus working frequency. Leadtek decided not to include the whole bunch of strange options for memory controller adjustment, and provides only the basic set of parameters: CAS Latency, RAS# to CAS# Delay, RAS# Precharge and Active to Precharge Delay. Moreover, the BIOS Setup also doesn’t allow to enable/disable ECC support.

As for overclocking friendly features, Leadtek K8N Pro looks much more attractive than the other testing participants. First of all, I would like to draw your attention to the fact that the BIOS Setup of this board allows changing the CPU clock frequency multiplier. Today this feature is not that valuable any more, to tell the truth, because AMD Athlon 64 3200+ allows setting the multiplier only up to 10x, i.e. you cannot actually overclock this processor by increasing the clock frequency multiplier. However, in the future, when new Socket754 CPU models arrive, this feature of Leadtek K8N Pro may turn out very useful.

The bus frequency of Leadtek K8N Pro can be adjusted from 200MHz to 300MHz with 1MHz increment. The AGP/PCI frequency, which is changing independent of the processor bus frequency on any NVIDIA nForce3 150 based mainboards, can be adjusted within 66MHz-120NHz interval. The Voltages adjustment page is very convenient and easy to use. When you adjust processor Vcore, Vdimm or any other voltage, you immediately see the new parameter value. This certainly allows to reduce the risk of accidental mistakes, when these potentially dangerous parameters are adjusted. The processor Vcore can be set to 2.5V, 2.6V, 2.7V or 2.8V. Moreover, K8N Pro also allows changing the Vagp (the available options are: Default, 1.6V, 1.7V, 1.8V) and the chipset voltage (the available parameter values are: Default, 1.7V, 1.8V, 1.9V). If the mainboard wouldn’t boot up in case of over-overclocking, the CPU and memory settings would automatically be reset to default values.

As a result, I have to admit that if it hadn’t been for the bad PCB layout, the overall impression made by Leadtek K8N Pro could have been highly positive, despite the problems we had with the BIOS at first. However, I have to stress that the mainboard is highly inconvenient to use although its boasts a few unique features, which are a big advantage, for sure. Although, if you are ready to put up with assembly problems and not very rich set of accompanying accessories, Leadtek K8N Pro may appear a pretty good choice for your system. Especially, since it is included into the list of mainboards recommended by AMD for use with their Athlon 64 3200+ CPUs.
