Default Re: 3.40 GHz Causing issues?

I need 1.36v for 3.2 and can prime 3.6GHz on 1.46v. 1.5v for 3.4GHz or lower seems kinda high. Sometimes folks believe they have stability problems with their CPU when it is often the memory. They run it at high speed with tight timings and not enough voltage to keep it stable.

You fellows with high voltage on the CPU @ a lower clock might want to try setting your ram and CPU to a 1:1 ratio with average timings like 5-5-5-15 then see if your CPU can hold it's current clock with less voltage. If you really want to remove ram from the equation while you experiment go even more sloppy, like 5-6-6-18.

I always find my max CPU OC on a 1:1 ratio and sloppy timings then tighten up as much as I can while maintaining stability.

I don't need to increase any motherboard voltage on P35 other than vcore until I hit a 423 FSB on a 9x multi with Quad core, then I need to increase CPU VTT to keep it stable. That one is crucial for me @ 3.8.
