I have problem with voltage on my sempron 3000+. I can't pass 1.7v vcore voltage, system wont boot, its freeze after win xp welcome window. Cooling is not problem, TT BT vx, PSU is ok, like they have some kind of overvoltage protection or something similar. I try increase vdimm voltage up to 2.5v and work fine, no problems.
I'am not OC rookie, i try several different combinations, low/high htt, 2x,3x,4x htt link, different mem dividers but still nothing, cant pass 1.7v vcore.
My 24/7 rock stable settings is [email protected], 3x htt link, mem [email protected]
