I'm running my 920 at 3.8 (19x200) on 1.18 vcore and 1.2 qpi. OCCT temps stay between 68-72c. I've tried for 4ghz a coupe times, but never got it stable without a huge voltage bump, so I focused on 3.8 and lowering my voltage. I keep wanting to get more speed out of this chip, but it feels like the voltage difference is too much for another 200mhz. Should I just call it good at this point?
