    Note: this thread is about overclocked i7-3770 processors, not the 3770K. If you have a 3770K there's a thread for that.

    The ability of some motherboards to slightly overclock some 3770 CPUs (we haven't run an exhaustive survey) has been discussed in some other threads:

    If you do manage to overclock your i7-3770, share the info here.
    And make sure you supply adequate cooling!


    Using my experience overclocking a 3770K, I tweaked the turbo ratio and voltage of this 3770 and quickly got to a stable 4.1 GHz setup. My result:

    i7-3770 in GA-Z77-D3H (see build post)
    Cooler: stock Intel cooler
    Clocked to 4.1 GHz, with a V[sub]core[/sub] offset of -0.100V.
    Temps:
    (Ambient: ~25C)
    Idle/general: 33-45C
    Prime95/large: 74-79C
    Prime95/small: 79-82C​
    64-bit Geekbench: 15180

    As far as I can tell that's right in line with reported results for a 4.1 GHz i7-3770K.

    The fan on the Intel cooler goes up to 2140 rpm under load and if I put my ear near the back of the machine I can hear it, but that requires crawling under the desk. There's enough background aircon hum here that the noise is a non-issue.

    Yeah, your RAM is lifting your overall score a bit over my CL10 Ripjaws.
    But a Geekbench tryout in 64-bit mode? What's the trick?

    I mainly reduced the voltage to shave off some heat under load (without it my temps were peaking close to 90C). What cooler are you using?

    I have a Scythe Mugen 2 and I'm very happy with it. After a night with prime95 running, the temps were under 70°C.

    In idle the tems are usually under 30°. I have a Fractal Design Define R3 tower with 4 case fans and the cpu fan. All fans are on 7V, it's very quiet and super cool.

    @DBP I'm using a GA-Z77X-UP5 TH with the 3770 (non-K). I was wondering what settings you used in bios to get to stable 4.1 overclock? Thanks for any info.

    The basic info was actually in the first post.
    Increased all the turbo multipliers to 41, and in the voltage controls set V[sub]core[/sub] to Normal (instead of Auto) and input an offset of -0.100V. I could do more experimentation and tweaking with different values, but this has turned out to be stable.

    Thanks, I'll mess a bit when I have time and let you know how it goes.

    Here's mine. I tried lowering vcore, but wasn't stable, so I did as HaxXxus did and just changed turbo ratios to 41. I get 15654!

    I have 32GB Corsair Vengence. Highest temp in short testing time was 81C with stock cooler.

    Congrats. Main reason I tweaked the offset was to reduce the temps slightly.

    From your Geekbench scores I'm guessing you're using 1600 MHz CL9 RAM?
