Joshwaa,
I poked into my bios to check settings. There are 3 different "MCH" settings. All on [Auto]. Are you referring to the MCH Core setting which looks to be at 1.100V on [Auto]? Is that what I should change to 1.200V taking it off [Auto]?
Also, I installed SpeedFan 4.40 and it shows Vcore1 at 1.36V (same as CPU-Z) and 1.90V for Vcore2 (which really freaks me out given CPU-Z doesn't show Vcore2). I haven't changed any settings yet. I'm still at FSM 358 and memory multiplier at 2.00B with everything else on Auto/Enable (e.g., power saving settings).
Please confirm if MCH Core is the setting you were referring to change to 1.200V, and if I should be freaking out about Vcore2 reading 1.9V which is way above Intel recommended max I think for an E6300.
Many thanks.
