Hi,

I've got a 2600K overvlocked to 4.5 Ghz. It seems to be stable at load at 1.23v, but at idle, the vcore drops back to 1.19v and occassionally I get BSODs when nothing's happening.

I've always been used to the vcore reducing on load rather than increasing on load. Is this normal on sandy cridge processors? It's on a msi P67 GD 55 mobo.

Thanks.
 
it happens. mostly because load line calibration (LLC) typically only activates during full load. just increase the voltage to 1.25, will most likely solve the idle voltage problem.
 
Thanks.

I think I have it on auto.

Maybe then it's better to disable it? That way I actually get vdroop and vcore at load is not higher than needed (i.e.lower load temps). It may mean I need to set the bios vcore higher, and it will stay high at idle (so higher idle temps - which is fine right?)

Right now it's 63 degs with a Prime 95 load, with 27 deg ambients. Problem is that the ambients here can easily get up to 35, and I have no idea how much temp these chips can take long run.
