Asus K8N Motherboard Features
Extraordinary Motherboard for Everyday Computing
The K8N is all about the flexibility of hardware choices and the availability of hi-end specs. The K8N not only offers everything you need, but we insist on providing everything you will need : Serial ATA ports, 8-channel audio, optical S/PDIF out, advance RAID options, even professional-grade native firewall to take care of the security concerns! Make your smartest choice for everyday computing with the K8N!
The K8N Supports AMD Athlon64 and AMD Sempron processors: The AMD Athlon 64 processor is based on AMD64 technology, which represents the landmark introduction of the industry's first x86-64 technology. The AMD Sempron is designed to give everyday computing compelling performance at an incredible value
Serial ATA ports
K8N integrates 2 Serial ATA ports for your storage needs. Serial ATA is the next generation ATA specification that provides scalable performance for today and tomorrow. With up to 150MB/s data transfer rate, Serial ATA is faster than current Parallel ATA, while providing 100% software compatibility.
NV Firewall is a high-performance, network-level firewall integrated into K8N. It has professional grade traffic inspection capabilities and advanced management features. In addition, NV Firewall also has unique anti-hacking features not found in other PC firewalls! Because it's native, NV Firewall eliminates interoperability issues, improves throughput and protection, with no extra cost to your pocket or CPU resources!
AI Audio (8-channel Audio)
The ALC850 has eight channels of 16-Bit DAC, a stereo 16-Bit ADC, and an AC97 2.3 compatible multi-channel audio designed for PC multimedia systems. The CODEC can also automatically detect and identify what types of peripherals are plugged into the audio I/O jacks and notifies users of inappropriate connection. No more confusion of Line-in, Line-out and Mic jacks.
Whenever BIOS gets corrupted, ASUS CrashFree BIOS 2 allows users to reboot the computer and perform an smart auto-recovery procedure through the motherboard support CD.
ASUS K8N offers robust overclocking options to maximize your system performance.
SFS (Stepless Frequency Selection) from 200MHz up to 300MHz at 1MHz increment
CPU, Memory and AGP voltage adjustable
ASUS C.P.R.(CPU Parameter Recall)
You can convert your favorite photo into a color boot logo for a more colorful and vivid image on your screen.
Instant Music Lite
Through this unique feature, K8N is conveniently designed to allow users to enjoy their favorite music without the need to enter Windows.
ASUS EZ Flash
With ASUS EZ Flash, you can update BIOS before entering operating system. No more DOS-based flash utility and bootable diskette required.
C.P.R.(CPU Parameter Recall)
When the system hangs due to overclocking failure, there is no need to open the case to clear the CMOS data. Just simply restart the system, the BIOS would show the previous setting and then users can amend the CPU setting again.
8 USB 2.0 ports support
USB 2.0 is the latest connectivity standard for next generation components and peripherals. Backward compatible with current USB 1.1 peripherals, USB 2.0 delivers transfer speeds up to 40 times faster at 480Mb/s, for easy connectivity and ultra-fast data transfers.
