Lastviking! Hey man! how are you doing?

Well using more volts than the sticks like doesnt make sense, you only get worse results. The more tight the timings the higher the sweet spot, but even for 665 the highest sweet spots are 2.25v. Well im using a p5k3 so i cant use more than 2.25v...
So i guess with cas665 the max that makes sense for some sticks is probably 2.35v, for cas5 maybe up to 2.45v but i dont think cas5 is worth it and cas6 and 7 make most sense. so the max voltage that makes sense to use is 2.3v and i doubt it will die at that voltage, unless it runs hot of course...

You have a lot of experience with mem, have you ever experienced something like this before? I never had any mem that had a sweet spot for voltage and didnt like more. if it ran too hot it oced worse or gave errors, sure, but thats not the case here.
