My E6400 is 100% stable at 375FSB with only 1.35V but to get stability at 400FSB requires 1.475V. Intel states that the absolute max Vcore is 1.55V but that reliability and longevity will be greatly reduced. IMO <1.5V should be safe for long term use with sufficient cooling but I sure don't like the way my load temp runs 60C at 1.475Vcore vs <50C at 1.35V. If Core Temp truly is more accurate than the bios, that would add ~10C to those temps. :eek:
I know to expect any cpu to hit a 'wall' at some point and Vcore demands to rise quickly but with so many people hitting 3.2G+ with ease at less than 1.475V, I wanted to get some opinions.
I can actually run Windows and BM at 3.2G with only 1.4V and it is Orthos stable for small FFTs and Gromacs but it kept failing large FFTs until I bumped the Vcore to 1.475V. I can't help but wonder if my OCZ Rev. 1 ram isn't somehow responsible but I can't for the life of me figure out what raising the Vcore could possibly do for ram instability or why the CPU is failing large FFTs which I thought was more geared towards testing ram. :confused:
TIA
