Hello. Sorry, but the experts out there will probably groan at another 'no nothing newbie' but here go's. I have an XP2600+ 166FSB on a version 2.0 A7N8X-X with Crucial DDR PC3200 512K RAM. I have been experimenting at trying to overclock and frightened myself to death. I had read on another forum that it would be OK to up the FSB to 200 (Default 166) and vcore to 1.7 (Default 1.65), but when I tried to save BIOS, PC would not finish boot. It just hung and told me CPU speed was incorrect, boot was in safe mode and to reset CPU speed to correct setting. Can I safely OC my system without wetting myself and thinking I've fried something? Any advice/useful links greatly appreciated. Thanks.
