I tried to beat an overclocking robot and failed
Extreme overclocking is hard. I had my first taste of this delicate hobby at last year's Computex, in which, with a lot of back and forth between pouring liquid nitrogen and torching, I managed to push Intel's 4.2GHz Core i7-7700K processor to an epic 7GHz. Still, I had it easy. Professional overclockers from G.SKILL and HWBOT had set everything up in the first place. Even the pros can find this all a little mundane. EVGA's Vince "Kingpin" Lucido and Illya "Tin" Tsemenko are well-known for their GPU-overclocking records over the years, but they, too, grew tired of the tedious "monkey work," to the point where they decided to build a rig that could overclock itself. The result is the Roboclocker, a PC that can intelligently and efficiently pump liquid nitrogen to both its CPU and GPU. While this may not be the first automatic liquid-nitrogen-overclocking rig, it's the first of its kind to actually break records.
Overclocking to 7GHz takes more than just liquid nitrogen
Over the years, I've been fascinated by two kinds of events at Computex: esports and extreme-PC-overclocking competitions. I doubt I'd ever make it as a professional gamer (I'm more of a Counter Fight kind of guy than a Counter-Strike man these days), but I'd jump at any opportunity to pour liquid nitrogen onto a PC motherboard, because even if I screw something up, chances are I'd still look cool doing so. It just so happened that at this year's Computex, gaming-accessory maker G.SKILL invited me to its extreme-overclocking workshop behind its contest stage. As a total newbie with absolutely zero knowledge of overclocking, I quickly took up this offer.

Visualized: Intel's Haswell Core i7 overclocked to 6.88GHz on an ASUS motherboard
After winning yesterday's Corsair Overclocking competition at Computex, the same folks were brought over to ASUS' ROG event earlier today, where they overclocked an Intel Haswell Core i7-4770K from its typical 3.5GHz to a staggering 6.88GHz -- just a tad less than yesterday's 6.98GHz -- on an ASUS Maximus VI Extreme motherboard. As a bonus, the DRAM frequency was also pushed to 4.1GHz, which is believed to be the fastest yet on Haswell. As usual, the overclockers poured liquid nitrogen onto the chip every now and then to keep it cool, thus giving us the above photo opportunity. %Gallery-190236%
AMD Trinity APU overclocked at 7.3 GHz, kept cool with liquid nitrogen
AMD's Trinity APUs have only been in the wild for a few days, but some have already taken on the challenge of pushing the new desktop silicon to its limits. By giving the A10-5800K model 1.956 volts, disabling two of its cores and cooling it with liquid nitrogen, overclockers were able to push the chip to 7.3GHz. Air-cooling and 1.616 volts squeezed out 5.1GHz without sacrificing any cores. If you're a mere mortal who's fresh out of liquid nitrogen (or never had any to begin with), you should be able to comfortably bump CPU performance by roughly 10 percent and GPU speeds by 15 to 17 percent.

Bulldozer world record re-broken by Andre Yang with a 8.58GHz victory lap
There you have it, folks. Floating over this text is the CPU-Z record that proves it: four days after Andre Yang broke the chip speed overclocking record with AMD's Bulldozer, he's done it again. The chip maker was eerily prescient when it said it expected others to beat the record and that unnatural confidence in the silicon has paid off. Last time, Yang managed to push only 30MHz over the previous record, this time he's found a further 123.3MHz -- making the total chip speed 8.58GHz. The secret to his success was in increasing his chip voltage (2.076v compared to 1.992 last time) and over-liberal use of liquid nitrogen. Maybe he could convince Sunnyvale to loan him a massive vat of liquid helium to get ever closer to the goal of 9GHz -- just make sure you don't pick up the check for the shipping and handling, okay?
Federal Excess: FedEx introduces liquid nitrogen-cooled biotech shipping, we can envision other uses
Just think about this the next time a FedEx van comes speeding past you -- that four-wheeled transporter could be carrying containers equipped with liquid nitrogen cooling that keeps its innards at a chilly -150 degrees Celsius. Don't worry, though, says FedEx, the use of dry vapor is actually safer than the currently used dry ice and classifies this new methodology as non-hazardous. While we may like to poke fun, it sounds like a pretty legitimate boon for healthcare and biotechnology shipments, which can now be maintained at a deeply frozen temperature for up to 10 days at a time. FedEx will provide the self-sufficient container and collect it upon delivery of the goods, while also monitoring its condition during transit. No word on whether or when DiGiorno will be signing up for the service. [Thanks, Pavel]
TweakTown slathers four Radeon HD 5870s in liquid nitrogen, crushes some benchmarks (video)
The PC hardware community recently discovered that quad-SLI was a huge waste of cash, so when we heard that TweakTown were stringing together four Radeon HD 5870s in a similar CrossFireX configuration, we figured they were about to throw away their time, too. Boy, were we wrong, because the hardware site never intended to seriously benchmark the rig as a viable gaming PC -- their intent was to make our jaws drop, and right now they're somewhere around our ankles. The contraption brought 3DMark03 to its knees with a soul-shattering score of 200,000 and achieved average framerates approaching a ludicrous four digits in Devil May Cry 4. How? Liquid nitrogen, of course. By attaching LN2-filled copper pots to each of the four already-powerful graphics cards and physically tacking on extra capacitors to direct the voltage, they bumped the Core i7-980X CPU clock to 5.8GHz and each GPU to 1250MHz, in what we think you'll agree is a healthy jump from 3.06 3.33GHz and 850MHz, respectively. Watch them build the mean machine after the break, and remember kids, don't try this at home. Update: The Core i7-980X runs at 3.33GHz, or 3.6GHz in Turbo Mode, not 3.06GHz. Our bad!
OU professor submerses laptop in liquid nitrogen, smashes it to prove a point (video)
Hey, students -- pay attention. Not to us, mind you, but to the syllabus provided by your professor. Kieran Mullen, a physics professor at the University of Oklahoma, has a fairly strict rule about gadgets in class: there won't be any, ever, under any circumstances. Balk all you want (understandable given his own clipped-on cellie), but if you sign up for this guy's class, you'll be flipping your phone to "off" and leaving your laptop in the dormitory. And if you try to blaze your own path and slip that netbook into the back row, you might leave bitterly disappointed. As you'll see clearly in the video past the break, Mr. Mullen sought to make a visual point that laptops weren't allowed in class (he calls them "a distraction"), and while it seems that the whole stunt was premeditated, most students acknowledged that his point was driven home. In short, he took a defunct machine, submerged it in liquid nitrogen, and proceeded to make the following statement: "This is just liquid nitrogen, so it alone won't hurt the computer. But this will." Find out exactly what "this" was by hitting that 'Read More' button there on the lower left. [Thanks, studentatOU]
Liquid helium trumps liquid nitrogen at AMD's Phenom II overclocking love-in
Remember late last year, when AMD poured out the liquid nitrogen to boost its new Phenom II X4 to a ridiculous 5GHZ? The company's factory overclockers apparently had a lot of leftover LN2, so they invited a crew of others to come over and splash some around on a set of new Phenom II X4 955 Black processors. After burning through a ridiculous 80 gallons of the stuff they rolled out the even colder liquid helium, which led to a maximum benchmark of 6.89GHz -- more than twice the quad-core processor's 3.2GHz rated speed. In these tough economic times it's good to see that one company at least is still willing to take things to great excesses at the expense of Earth's natural resources.
Liquid nitrogen-cooled MSI Wind U100 overclocked to 2.3GHz
When MSI rolled out its v1.09 BIOS, we're willing to wager it absolutely did not have anything like this in mind. The mad scientists in Team Australia are at it again, this time overclocking a netbook to the point (almost, anyway) of implosion. The unafraid members grabbed hold of a hopeless Wind U100 with 2GB of RAM, hooked up a little liquid nitrogen and proceeded to push the poor 1.6GHz Atom N270 CPU to an amazing 2.385GHz. No telling how quickly the whole thing was over, but still, this is pretty ridiculous, mate.
AMD overclocks the snot out of Phenom II processors
No, you're not looking at some high-precision, multimeter-laden kegerator; the above is a picture from a recent AMD event in which things apparently got a little out of hand. The company started by talking up its upcoming Dragon platform (Phenom II X4, Radeon 4800 graphics, and 7-series chipset), took a few moments to discuss how its new 45nm chips will use 30-50 percent less power than their predecessors, and then threw all notions of sensibility out the window in an attempt to see just how fast the darned things could go. A Phenom II X4 managed 4GHz with air-cooling, 4.4GHz with a refrigerated setup, and finally a "stable" 5GHz on liquid nitrogen. That's mighty fast, but will the chips be quick enough to tackle Intel's mighty Core i7 when stripped of their fancy-pants cooling appendages? We'll see when they ship early next year.

OC Team Italy takes P4 to 8.18GHz
Nah, 8,180MHz can't hold a candle to 500GHz, but on the long road of overclocking Intel's Pentium 4 where there is an increasingly brief amount of time available to brag before being trumped, the zany Italians have crowned themselves champs once more. Not content with just hitting 8GHz with a "Cedar Mill" Pentium 4 631, OC Team Italy managed to push that very model an additional 179MHz by tweaking the FSB. The final results yielded a 173-percent overclock, and while this here setup may run stable for a continued period if placed at the depths of Antarctica, we can't imagine this being too feasible for the common man to replicate and actually utilize.
