Intel Ivy Bridge Processor Hits 7GHz Overclock Record

Posted by timothy on from the who-ordered-this-keg-of-nitrogen? dept.

MojoKid writes "Renowned Overclocker HiCookie used a Gigabyte Z77X-UD3H motherboard to achieve a fully validated 7.03GHz clock speed on an Intel Core i7 3770K Ivy Bridge processor. As it stands, that's the highest clockspeed for an Ivy Bridge CPU, and it required a steady dose of liquid nitrogen to get there. HiCookie also broke a record for the highest memory speed on an Ivy Bridge platform, pushing his G.Skill Trident X DDR3-2800 memory kit populated in four DIMM slots to 3,280MHz. Not for the faint of heart, the record breaking CPU overclock required that HiCookie pump 1.956V to the processor, according to his CPU-Z screenshot. The CPU multiplier was set at x63."

  1. One core, two threads? by ZeroSumHappiness · · Score: 5, Interesting

    Can someone explain why it's reporting one core, two threads?

    Is this:
    1. Set to one core to get a better heat profile?
    2. Only using one core for the test?
    3. Using all cores for the test but only reporting one core's results?

    Because if it's 1 or 2 I think I see some problems with this benchmark.

      Generally they disable all cores but one to achieve these clock speeds.

      I don't think you really understand the purpose of this. He's not "running" anything, so it doesn't matter how many threads. An overclock like this is only done to say that it can be done and that you did it, it's not practical in any way shape or form. You would never try to run an actual application on this, odds are you couldn't maintain system stability for more than a few minutes, and even if you did the cooling and power requirements are well beyond reasonable.

      It's the same performance as a 1.6Ghz quadcore with just air cooling

      Except that it's not. For some theoretical computations that could be made perfectly parallel, this might be nearly true. However, in most cases (presently), the limiting factor in computation speed is the clock speed of an individual core.

    This is essentially the only way to run this experiment, if you run all the cores at this speed, fusion is initiated, a black hole forms and time runs backwards!

    7 GHz processor speed and it still takes 10 seconds to load Windows. . .
