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.
Apple's slim MacBook Pro design could be holding back its i9 CPU
The 2018 15-inch MacBook Pro lets you crank up the processor power by swapping in an Intel 2.9GHz six-core Core i9 CPU for an extra $300. But the chip seems to be struggling when it's handling power-hungry tasks, to the point where the average clock speed is vastly below the advertised performance of the CPU. Some tests even showed that it fared worse than the i7 model.
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.
How to build a high-end, overclocked PC (as written by an idiot)
This is not an article from a PC virtuoso who builds water-cooled, quad-SLI gaming rigs with not a wire out of place. Nope, it's by a guy who's fantastic at buying stuff on Amazon, but more likely to start an electrical fire than build a sophisticated PC. But that's never stopped me before! So, with a screwdriver in one hand and unmerited self-confidence in the other, I set out to build an overclocked Intel Haswell-E Core i7 machine for video editing, 3D animation and light gaming. Whatever could go wrong?
Intel leak reveals 8-core Haswell-E series desktop CPU for late 2014
Now that Haswell's available in consumer-grade laptops, it's time to look at what's next on Intel's to-do list. A leaked slide-deck is claiming that Haswell-E, the enthusiast version of the chip, is coming in the second half of 2014. The documents also promise that Intel will axe the 4-core base model in favor of 6-and-8-core editions of the CPU, which can pack up to 20MB of L3 cache. At the same time, the company is likely to release the Wellsburg motherboard chipset, which can support DDR4 RAM with a clock speed of up to 2,133MHz. If it's all to be believed, then we have one word of advice to the overclocking community -- best start stocking up on liquid nitrogen.
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. For the full specs on this particular overclock, hit the source links below.
Raspberry Pi's new turbo mode boosts performance by roughly 50 percent, doesn't void warranties
Giving a Raspberry Pi extra voltage is a quick way to squeeze out additional processing power and void its warranty, but the folks behind the tinker-friendly board have devised a turbo mode that boosts performance by roughly 50 percent while keeping warranties intact. After studying the effects of temperature and voltage on the hardware's lifespan, the team found that dynamic overclocking and overvolting doesn't affect the Pi's health appreciably. As a result, speeds can be pushed from 700MHz to 1GHz only when additional horsepower is needed, and things are reined back in when the CPU grazes 185 degrees Fahrenheit (85 degrees Celsius). Benchmarks show the extra computing oomph makes the Pi 52 percent faster on integer, 64 percent speedier on floating point and 55 percent snappier on memory tasks. The new mode is available in the latest firmware update, which also includes temperature and frequency widgets, better analog audio, improved USB performance and support for WiFi dongles out of the box.

Digital Storm unveils X17E gaming laptop, pushes your CPU to 4.5GHz for frenzied fragging
Specialist gaming outfit Digital Storm has busted out its new X17E gaming laptop, designed to keep you entertained without too much grunting. The 17-inch unit comes with a 1,920 x 1,080 display, a choice of GeForce GTX 680M or Radeon 7970M and an Intel Core i7-3910XM, which the company's engineers reckon can be stably overclocked to a whopping 4.5GHz. It's got the usual raft of features you'd expect in a high end unit, including support for 32GB RAM, USB 3.0, eSATA, Blu-Ray and a backlit keyboard you can tweak to your needs. The base model will be out at the end of September, setting you back $1,753, while a signature edition with a custom paint-job will come later, and cost you more.
Google Nexus 7 overclocked to 2GHz, punches well above its weight
The stock Nexus 7 peaks at a 1.3GHz clock speed when it's at full burn. That's certainly good enough for the $199 price tag, but eager adopters have just hit a new record in trying to wring out even more of a bang for the buck. Courtesy of a custom Elite kernel from XDA-Developers' Clemsyn, the Tegra 3 in the mini tablet will scale all the way to a heady 2GHz. You'd be right in suspecting that it leads to some dramatic speed boosts: the Nexus 7 at this pace can put a Transformer Prime to shame in common benchmarks, let alone most smartphones. Reaching the loftier heights of performance does require nerves of steel, however. The Elite kernel is very much a rough build that the creator doesn't yet trust with the public, and NVIDIA's processor is already known to get toasty under significantly added stress. There's hope a refined kernel will make for a safer venture into unknown territory. If you can't wait to throw at least some caution (and the warranty) to the wind, though, hit the second source link for code that will reach a slightly less melt-prone 1.8GHz.
AMD Radeon HD 7970 could get 'GHz Edition', put the hurtz on NVIDIA
AMD's Radeon HD 7770 and 7870 reference cards already sport 1GHz clock speeds, but so far the high-end flagship 7970 has been stuck at 925MHz. That'd be no big deal, perhaps, were it not for rival NVIDIA's benchmark-stealing GeForce GTX 680, which autonomously adjusts its clock speed on the fly and easily hits 1.2GHz under the right conditions. But while NVIDIA has yet to roll out its full stack of 28nm cards, AMD is finding plenty of time to play catch-up. According to Australian site Atomic MPC, the company has revealed that the manufacturing process of its next-gen GPUs has improved to the point where the same average voltages can yield much higher clock speeds. Recent chips can reach 1.25GHz without struggling, which means a conservative "GHz Edition" of the 7970 can now safely be rolled out, of course with scope for much higher overclocking on third-party boards with more robust coolers. By the time the battle between Red and Green reaches full-swing, it might not be so easy to call a winner.
Origin PC EON15-S and EON17-S gaming laptops available now, priced from $1,525
In the market for a beastly portable gaming rig that won't break the bank? Origin PC today announced availability of its EON15-S and EON17-S gaming laptops, with pricing starting at $1,525 and $1,576, respectively. You'll of course still be able to hand over an arm and a leg depending on how you opt to build out your system, but considering that the base model is priced at nearly half the amount its predecessor was when it was announced this time last year, we imagine additions will wield a softer blow than they did in 2011. Both systems include Intel HM77 Ivy Bridge chipsets, NVIDIA GeForce GTX 660M, 670M or 675M graphics with Optimus power-conservation technology, and a 5.1 ONKYO surround sound system. Both cases offer unique designs, with black, red, silver or custom finishes, and a colorful backlit keyboard. What else could you possibly need? Perhaps a press release and a few more pictures -- and we've got both for you right here.
Digital Storm launches Aventum range with Cryo-TEC cooling system
The last thing you want when things are getting hot in the battlefield, is for things to start heating-up under your desk too. Digital Storm's been back in the lab, looking for ways to prevent just that, and thinks it's cracked it with the new Aventum system. It's the first to be kitted out with the PC-maker's Cryo-TEC liquid cooling mechanism, and boasts a thermal exhaust, five software-regulated "zones" and no less than 13 configurable fans. The range starts with an Intel i7 2700K core, 16GB RAM, 120GB SSD (1TB HDD) and a GeForce GTX680 for $3,859. If your pockets are even deeper, then you might fancy the 2x dual Xeon E5-2630 hexacore-totin' system with 32GB DDR RAM, and three-way SLI (with the same GeForce GTX680) for a jaw dropping $7,856. With a price like that, however, it's probably your credit card that'll need cooling down. Digital Storm is taking orders as of today, and full details of the range in the PR after the break.
Origin PC boosts Genesis factory clock to 5.7GHz, reveals new EON gaming laptop design
Origin PC has been spitting out 5.2GHz Genesis desktops for a few months already, but apparently some people wanted more. Thanks to a new 'Phase Change' cooling system that'll be available from late Q1, they're about it get it: a Core i7 2700K system factory clocked to 5.7GHz. Cooling controls and temperature displays will help you to establish the proper balance of power and pollution, while lifetime technical support (which now applies to all Origin PCs in the US) is just a phone call away in case you need to share the rush. There's even an X79 mobo inside, offering scope for a Sandy Bridge E upgrade, plus NVIDIA's GeForce GTX 580 in four-way SLI. Origin has a little something for portable gamers too: a refreshed A-panel on the EON17-S and EON15-S laptops to help you strike the right note of grinning malice in front of your LAN victims. It's not yet clear how these updates will affect pricing, but there are plenty of clips on YouTube that'll show you how to smear thermal paste on your credit cards. Full PR after the break.
MSI launches Big Bang-XPower II motherboard for militant overclockers

The Big Bang-XPower II comes packing the features you'd expect of any gamer-friendly MoBo, including four-way SLI and CrossFire support, PCIe 3.0, eight DDR3 slots and plenty of extra power connectors for hooking up your high-powered parts. And the company is taking care of overclockers too with military grade components and features like Direct OC, which lets you tweak your CPU's frequency with the push of a button. Check out the PR after the break and hit up the source for a few more pics.
Core i7 gets pushed to new heights, overclocked to 5.6GHz (video)
Sure, it's not quite the 8.58GHz achieved by a liquid nitrogen-cooled Bulldozer, but professional overclocker Hicookie did manage to set a new record for a Core i7 3930K by reaching 5.6GHz -- with the help of the aforementioned Dippin' Dots refrigerant, of course. Hicookie unlocked the insane overclocker achievement with the help of an X79 motherboard from Gigabyte, which also gets some recognition for being the first such board to reach a multiplier of 57. For a rather long and dull video of the super-speedy i7 getting pushed to the brink of destruction, head on after the break.
Microsoft leak reveals hotfix for underperforming Bulldozers
AMD's Bulldozer silicon is enormously powerful, but most software isn't configured to schedule threads for the faux-16 core design. Windows can only see the chip as a quad-core CPU and will randomly assign threads, which ruins the point of Bulldozer's "Turbo Core" design. Microsoft inadvertently revealed it had teamed up with the chipmaker to fix the problem when it prematurely released a hotfix for Windows 7 and Windows Server 2008 R2. Initial tests showed that it could improve performance by up to seven percent, before it was pulled -- Microsoft conceding that it wasn't quite ready for prime-time.
Zalman reportedly entering the graphics card market, merging GPUs with cooling solutions
Recently leaked slides suggest Korean computer outfit Zalman will soon jump into the ever-expanding graphics card market, initially partnering with AMD on its Radeon series. Known best for its quiet computing technologies, the company's move to infuse GPUs with cooling solutions could enhance the performance of the cards, making overclocking a lesson in simplicity. The slides only show the AMD 6870, 6850, and 6770, but it's feasible more models will appear when official news is released. Given AMD's many board partners, differentiation is important to remain competitive and on their payroll -- graphics cards and their overheating habits is Zalman's cup of tea. Hopefully this brings more innovative products in the coming future (heck, we've already got GPU / NIC hybrids), perhaps as early as CES. Check past the break to view the specifications breakdown for the aforementioned cards.
Maingear brings Intel i7-3960X Extreme Edition chip, Epic Audio Engine to desktops, extreme gamers
Looking to add a dash of extremity to your gaming existence? Maingear's got you covered, now that it's added a second generation Intel Core i7 CPU to a handful of its desktop offerings. Today, the company announced yet another upgrade to its SHIFT, Quantum SHIFT and F131 desktops, with the addition of the Intel Core i7-3960X Extreme Edition processor. According to Maingear, this extra horsepower will provide gamers with a 34 percent improvement in performance at normal speeds, while offering similar enhancements in video editing and 3D rendering capabilities.
