    I need help getting the most out of my i7-4790K

    I have a stable 4.7MHz @1.27V overclock with 16GB RAM @2400 on a 15min realbench stress test. Realtemp core temps were:
    core1: min 33C-max 74C
    core2: min 32C-max 75C
    core3: min 33C-max 76C
    core4: min 31C-max 66C

    I tried to go to 4.8MHz started @1.30V and increased .01 up to 1.39V, I couldn't get stable and core3 hit 89C and I stopped the test! (cre4 never got above 76C). Should I be happy with 4.7 or is there something else to try to hit 4.8 or higher?

    It seems your cpu hit the wall at 4.7GHz so yep you should be happy with 4.7GHz.

    Thanks Nate, it runs great at 4.7GHz, just making sure I was doing everything I could. Any reason why core 4 is running so much cooler than the rest?

    It's normal for a core to run cooler than another.

    It's not unusual for one or two cores to run cooler than the rest.

    Plot twist...

    ...everybody has a ****ed CPU and is experiencing the same issue when in reality the cores should run just as cool as the other.
