    Hay gurus so recently a friend got a I5 3470 and i thought i would test it.
    And compare it to my old I3 2100 and new 3570k.

    I read ages ago you could play around with the cpu ratio in the bios or overclocking software like Asrock ETU.I was surprised at when i started my pc first boot the cpu was @ 3.2 then i rebooted with 3.6 and 4.0 and both seem to work and i see almost no temp chance with a Hyper 101.

    I did a video to show how to overclock hope its okay to post it.Would love to here your thoughts and opinions on this.

    Me unboxing it and installing it

    Yes, i5 3470 can be overclocked to 4 GHz on all cores with ASRock Z77/Z75 motherboards. And to 3.6 GHz on all cores on other manufacturer motherboards, also probably plus 100MHz for each core disabled/inactive.

    I just added that 4 GHz for i5 3470 requires ASRock motherboard and on other moatherboards it won't OC that much. You didn't mention this in video or OP.

    But, yeah, i5 3470/3570 with ASRock Z75/Z77 motherboards is great value.

    Intel allows you to overclock 4 bins above turbo on "locked" processors....which means it should overclock to 4.0ghz seeing as it has a 3.6ghz turbo clock. Doesn't matter which motherboard you have, 4.0ghz is the maximum clock for an i5 3470.

    Are you sure it does it on all cores?

    Basically, i5 3470 on non-ASRock boards should go up to 3.7 GHz GHz on all cores and 4.0 GHz on single active core.

    Yes I'm sure, called multicore enhancement. Asus was first to implement it in X79, gigabyte after. As rock was the last and implemented it in Z77

    MCE boosts all cores' clock to TurboBoost's maximum. That's 3.6 GHz for i5 3470, 3.7 GHz on i5 2500/2500K, for example. But does it allow to boost it to maximum Turbo AND add +400 MHz OC on all cores?

    Anyone here with non-K CPU and MCE compatible MB can confirm or deny this?

    Mine has MCE and it does.
    Also, gigabyte has it in their z68 sniper

    Sorry to bump this old thread, But I had to add this, I bought a i5 3470 about 5 moths ago, And The board that I got with it in a deal is a Biostar TZ77A, And it goes up to 4ghz on 2 cores and 3.9ghz on 3 cores, And 3.8ghz on all 4 cores. So that is what the chip will do on it's own. I have not heard of any motherboards allowing any non K chip to allow the chips max multiplier on all 4 cores. All non K chips have a limit on all 4 and a limit on 3 and a limit on 2 with each 1 bin higher than the other. But you can up the bclk a tad to allow it to go to 4ghz on all 4 cores. But that is it.

    ASRock Z75 and Z77 boards allow max multiplier on all cores. Biostar and probably other vendors don't have this feature.
