Hey guys, I'm trying to squeeze a bit more out of my Ivy Bridge 3770k and G.Skill 1600 DDR3 before I upgrade. If I bump up the multi to say, 40 as opposed 35, I can run stable at 4.0ghz, I can even bump it up to 4.2 using the multi. As soon as I increase the CPU frequency, even just a tiny bit, the PC doesn't boot. My guess is the RAM doesn't like the jump in CPU frequency, but I'm no expert. I thought the G.Skill modules were fairly good overclockers. It's not a heat issue or anything, if it was then surely it would boot long enough for the heat issue to arise? Is there something I am missing?
