Last night I reflashed my bios using the MSI live update to bring my driver version up to 5.8. 1st thing I noticed when rebooting all the bios settings had been changed back to the default & the system was now recognizing the chip as a 1800 XP From what I have read the FSB should be set @ 166 & the multiplier @ 15. However when I am in my CPU Ratio settings the highest you can select is 13. Is anyone else running this chip & mobo & can tell me what their BIOS seetins are under Frequency / Voltage & Under Advanced Chipset features? I am also wonder what the FSB spread spectrum should be set at? Any help at all would be greatly appreciated. Thank you!
