CPU Ratio Selection: CPU Ratio is the multiple that times the frontside bus frequency will equal the core speed of the installed processor. Whether the option is open or locked is determined by the installed processor. SDRAM Frequency: If [Auto] is selected, the motherboard will detect the memory module(s) inserted and assigns appropriate frequency automatically. Hyper-Threading Technology (for P4i45GV only): To enable this feature, it requires a computer system with an Intel Pentium®4 processor that supports Hyper-Threading technology and an operating system that includes optimization for this technology, such as Microsoft® Windows® XP. Set to [Auto] if using Microsoft® Windows® XP, or Linux kernel version 2.4.18 or higher. This option will be hidden if the current CPU does not support Hyper-Threading technology. 22
