Just posting my results since i have virtually the same build as you guys
I ran my Vcore at 1.25 stock.
Ram is 1555Mhz i think
All other settings are stock.
Cpu is currently doing 3.7ghz on stock voltage and is running in prime 95 for hours stable as ever.
I'm very happy with the ability of this chip to overclock over a ghz of speed on stock volts.
