What's XMP for the ram? Your sig still has a w3690 and DDR3 listed.
Sounds about right for your OC, you could maybe get another 100MHz out of her without going too high (I think mine will hit around 4150MHz, but I don't remember if that was at 1.4V or 1.45V) .With your cooling I'm sure you could handle a little more vcore (may go up to 1.4V), but according to AMD it does increase the risk or likelihood of degradation. Totally understandable if that's not worth it to you. I don't run an all core OC for daily driving, just enable PBO and Go.
