SpaceX’s Starship rocket prototype collapsed on itself this weekend
Another SpaceX test ended in failure this past weekend. A prototype of the company's Starship rocket, SN1, imploded in a pressure test late Friday night. Elon Musk acknowledged the incident on Twitter, sharing a video and writing, "It's fine, we'll just buff it out."
Pushing a 28-core CPU to its limits: 6GHz and beyond
I'm mesmerized by the way liquid-nitrogen vapor flows across the motherboard. There's something oddly therapeutic about extreme overclocking, especially when the cold air gently touches my skin, making even the tiniest bumps in clock speed the more worthwhile. There's probably no better place to see it in action than Taipei's Computex, where gaming PC memory maker G.Skill gathers the world's best overclockers for its OC World Cup event (with a $10,000 top cash prize). Our previous attempt to tame the 18-core Intel Core i9-7980XE was already rather ambitious, but this year, we decided to go all the way with the massive 28-core, 255W Intel Xeon W-3175X, a rare CPU gem that costs at least $3,000 -- if you can even find one. Our goal was to break the chip's records at the time: pushing it from its 3.1GHz base frequency to beyond 5.68GHz on Cinebench R15, or at least beyond 6.5GHz via the more lightweight CPU-Z validation. With this many cores, it posed a much bigger cooling challenge to run at higher speeds, especially compared to the quad-core i7-7700K I tinkered with the year before.
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.
