guys just one question, i have this dfi nf680i lt with 4CTST521 bios and a Q6600 B3 but i'm not able in any way to set the multiplier to 8x...... i only need to low the multiplier from 9x to 8x for more testing to understand if mine is a cpu frequency problem or a bus problem..... but can't find out how to change it.... i've seen some of you in here are using it at 8x..... could you tell me how (if you have my same board of course)?
