Intel Ivy Bridge Processor Hits 7GHz Overclock Record 144

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."

    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.

        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?

          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, what you're seeing is how fast one core can go, given that all 4 running would quadruple the thermal requirements.

          Generally the purpose of doing this is for shits and giggles, you would not be able to actually use the computer configured that way since the cooling solution would run out pretty quickly. The most you can do for a functional system is to immerse in mineral oil, with SSD drives and not submerge the PSU.This is generally a non

            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.

              The main culprit there is Flash and a normal clocked single core is more than adequate for that.

          Nothing. but it does prove that with adequate cooling you can get to 7ghz on current generation silicon.
      • Thank you for confirming my suspicion. Obviously I have more interest in using rather than record breaking so I'd have liked to also see what it can do on all four cores under liquid cooling.

      AMD did better with 2 cores, now I would like to see a side by side comparison of actual tasks.

      • Except that AMD's 2 cores aren't actually 2 cores. They're 1 instruction fetch unit, 1 instruction decode unit, 1 floating point unit, and 2 integer units, so this is a very similar result, it's one CPU core that is able to do a bit of stuff at the same time as it does some other stuff, not really 2 cores.

      The point is that the CPU and the motherboard are all manufactured in such a way that the processor can work at a clock cycle so damn fast. That is precision. Not everything is about work/time. To your analogy, it's more like saying "We can have the engine do ten bazillion RPM! That's a quality engine! However, if you try to drive at that RPM, any flaw in the system can cause a huge amount of damage, so don't expect to drive it at that speed."

              NASCAR started with liquor running during Prohibition, so speed was more important than handling. Given that, I can kind of excuse the initial use of an oval track. But once the speeds got too high, they started restricting the cars and so the oval track was sort of an anachronism... very hard for me to get

            As with realistic overclocking, Rally racing has some relevance to the real world. They're driving on real roads, in varying weather conditions, unlike the stupid NASCAR bullshit.

        I know my P4 isn't as fast..... I know that every time I try to play an HD-quality movie, and it runs at quarter speed. The CPU is fast in cycles but slow in calculations.

    • Oh wait, no it can't. It also isn't quad core, and does about 20% of the work per clock.

      There are limits to GHz scaling. It isn't a situation of "Oh just make it faster," particularly if you want to hit a power budget. What has happened is that CPUs have gotten much more parallel, much more efficient per clock, and have gotten much better at vector math. My Sandy Bridge processor pulls like 80 Gflops on Linpack using AVX. Try that on a P4, let me know how it goes.

    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.

  • I don't have any liquid nitrogen, but I really, really like french toast. On a MacBook Air with an Ivy Ridge CPU, how many slices would I need to cook simultaneously to match the effects of using LN2?
