Ok, so i've got an AMD 6000+ dual core sitting on a Gigabyte GA-MA69VS-S2. I've lowered by DDR2 speeds to 667 instead of 800 (default for my ram), Changes FSB from 15x200 to 15x215, stepped of course letting each 5 extra FSB "burn in" for 2-3 days before stepping up another 5... so started off at 205, then going to 210, then 215... But as soon as I try to go to 220... I get BSOD after 5 minuets. This happened on both Windows XP MCE SP3 and the new Windows 7 RC. All voltages are at default values. It's not a heating problem as i'm still not poping 40C under load at my current OC. I would like to get this chip up to 3.4 in the long run, but I can live with 3.3. So, any suggestions?
