Intel 3570K HD 4000 overclocking

With Intel Extreme Tuning Utility I was overclocking my HD 4000 to 1500 mhz with additional 187,5 mV, according to this article:

They say 1600 mhz = additional 425,8 mV...
But I found another review on:
where they managed to overclock to 1600 mhz just with additional 226,6 mV!

My question is: How can I calculate the additional voltage for my 1600 overclock?
Currently, I run on 1500 mhz @ +187,5 mV, but isn't it too much?
Help :!

  1. why? a $50 video card would offer more performance than any OC'd hd4000.
  2. I don't know, HD 4000 is pretty good and better cards starts from $150 in my country.
  3. Every chip is different. They'll all need to have different voltages to run even at the same frequencies.
  4. So how can I find the correct voltage?
  5. Best answer
    By testing it out, like any other type of overclocking.
  6. Okay, thanks.
  7. No problem!
  8. HD4000 graphics is actually very capable. It can run 90% of the games out there with no problem. People think games like Crysis 3 are the rule for games. When they are actually the exception to the rule because most games don't require that much HP to run.

    New games like Transformers: Fall of Cybertron have great graphics and can run on MAX settings with HD4000 graphics. I've had HD4000 graphics on a laptop of mine with a i7 to go along with it. And I had no problem running games like Borderlands 2 and CODII Black Ops on lowest settings. Even MMO's like World of Tanks ran quite fine with low-medium settings and this games fairy graphics intensive.

    So by overclocking HD4000 graphics it'll only get even better performance. I was gaming on a 1600x900 screen, but I imagine that a 1920x1080 screen won't be much different and could still play the games I've mentioned. Although games like Crysis 3, Far Cry 3, Metro 2033, and Battlefield 3 probably won't be playable even at low settings. I'm sure you could still play them at 1200x800 resolution at lowest settings with 25-30FPS. So either way, you can enjoy almost every game. And for integrated graphics that's pretty good.
  9. Yep, and 3570K is a great cpu.
