Intel Ivy Bridge Processor Hits 7GHz Overclock Record

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.

      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.

      So... what's the advantage to having one core running at 7GHz versus four at standard clock speeds, assuming that whatever you're running takes full advantage of all the threads?

      No, these with these types of overclocks you can normally only run the system long enough to run CPU-Z and get a screenshot. The majority of windows services are not running, only one CPU core is running, and you are cooling it with liquid nitrogen that tends to boil away rather quickly.

      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.

  13. My middling, mostly working UD5H. by game+kid · · Score: 2

    I own the mentioned UD5H motherboard used for the record memory speed; I bought it to replace a very old P5B Deluxe. I am in no way jealous or unappreciative of HiCookie's feat, and the board definitely looks like something that can handle such a thing, but my experience with the board has been middling.

    I haven't had the freezes that people have mentioned on its Newegg page (thank the gods!) and things generally work, but Windows 7 64-bit simply refuses to hybrid sleep or hibernate, and after a non-hybrid standby to RAM, things subtly fuck up (no audio, and other devices I forget at the moment mess up), which means I have to fully reboot (really fun when waiting for big programs like Catalyst) or leave the rig on at FULL POWAH through the night or whatever. Arch Linux was working well at first (RAM standby and even disk hibernate if properly configured and I choose to boot from the Linux drive after the suspend), but updates seem to have made it less compatible with my audio (audio out works except through the standard green line-out...odd) and TV tuner (not detected), for whatever reason. (I left a few more details on a review on the Newegg page, minus the less-compatible part.) The P5B had no such problems: its audio had lots of RF interference through headphones (the UD5H has beautifully clear onboard audio when it works) but it suspended, automatically resumed from the suspended drive, and otherwise worked nicely.

    For me, a "middling" board is worse than a "horrible" one, because at least a horrible would be bad enough for me to undo all the cable connections and screw placements and attachments and all that to trade for something better (a very old backup PC I had started getting POST errors as I built the new one so combined with other factors it made referring to the internet kinda impossible...that was fun). With a middling one I simply tolerate the few problems because it mostly works. *shrugs*

    Sorry if that came off as a dumb ramble; just my experience with it.

    Actually, you are wrong. I'm not speaking for overclockers and in fact, I'm not even one. However, extreme overclocking is very valuable. It tells normal overclockers how much headroom they can expect (at least relative to another chip), it gives an indication of how robust the chip design and the process technology is.

    Your car analogy is completely wrong as well. A ricer analogy would be someone who uses a fancy case but does nothing to improve the internals. The analogy would be someone who takes a stock engine and tries to rev it to the maximum possible rpm by using any means. I imagine that many people would find this a valuable metric especially when they are comparing various engines, especially for specialized needs such as drag racing.
