NVIDIA makes GeForce GTS 450 official, promises beastly overclocking
Say hello to NVIDIA's GF106 core (please pretend you've never met before). The company's third Fermi desktop iteration is described as "a little more than half of the GF104 implementation," which in real terms means 192 CUDA cores versus the GTX 460's 336, reduced memory bandwidth with a 128-bit-wide bus and a lower number of ROPs at 16. These disadvantages are ameliorated by 783MHz graphics and 1566MHz processor clock speeds as well as a much more forgiving power profile -- the new GTS 450 cards will require just the one 6-pin power connector for auxiliary juice. Pricing is aimed squarely at conquering the market currently occupied by ATI's HD 5750, which, as we saw over the weekend, plants the 450 around the $130 mark. You'll have to read the reviews below for confirmation, but NVIDIA promises "awesome" overclocking headroom on its new card, going as far as to suggest stable 900MHz graphics clocks aren't out of the realm of possibility.

Overclocked, liquid-cooled Mac Pro trades noise for speed
I wonder if it's only a matter of time before Apple decides to go to a liquid-cooled solution rather than keeping with bigger and faster fans. In any case, one technically adept person over at Asetek didn't want to wait for that day. He went about not only water cooling an older 8-core Mac Pro, but overclocked it as well. The result was a much quieter system, with the same speed as a newer Mac Pro and at lower cost. I haven't noticed a Mac Pro to be all that noisy, but the quieter the system the better, especially when it's on or under your desk. What this guy didn't explain, though, was how much time and money it cost to outfit the older Mac Pro with water cooling. Would the time, effort and cost there still make it a worthwhile mod? Check out his full video after the jump.
Palm Pre hits 1.2GHz courtesy of SR71 Blackbird kernel, not for the faint-hearted
Whoa! After breaking the 1GHz barrier just three weeks ago, dauntless modder unixpsycho is back with yet another insane hack for the aging Palm Pre. What's new? Why, this "SR71 Blackbird" custom kernel, which simply pushes the poor little OMAP3430 processor up to 1.2GHz -- that's twice the original clock speed, just so you know. As glamorous as it sounds, potential users are triple-warned about this mod potentially failing the webOS device in one way or another, despite the built-in speed-scaling mechanism to cap the device at 55 degrees Celsius (131 in Fahrenheit). And needless to say, don't expect your stock battery to hold up for more than a few blinks once implemented. Good luck, pilgrims.
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!
Intel Core i7-875K and Core i5-655K unlock multipliers, better performance
Intel's back in its familiar saddle today with the unveiling of a pair of new CPUs, marking the start of a new K-series that will cater to the overclocker inside all of us. The Core i7-875K is a 2.93GHz quad-core unit, which can scale heights of 3.6GHz via Turbo Boost, or even higher if you have the patience, tenacity and appropriate cooling to make it happen. Review action for this chip shows it to be Intel's premier offering short of the enthusiastically overpriced and overpowered Core i7-980X. Even more affordable will be the Clarkdale-based Core i5-655K, which trots along at 3.2GHz (with a 3.46GHz gallop option), but response to it was a little more muted. It's a dual-core CPU, after all, and if you don't plan on exploiting that unlocked multiplier to achieve some madness above 4GHz, you might be better off looking elsewhere. In amidst all the mad benchmarking, we've also found a review of a Falcon Northwest i7-875K rig as well, so give it all a read if you're mulling over a desktop upgrade.

Overclocked ATI Radeon HD 5870 shootout: HIS, MSI and Gigabyte trade blows
ATI's Radeon HD 5870 first saw the (official) light of day in late September of last year, but the GPU has managed to age well. In the months since that original debut, we've seen an Eyefinity 6 Edition hit the market for multi-monitor maniacs, and quite a few factory overclocked options have also made their way out. The benchmarking gurus over at Hot Hardware scrounged up three of the latest and greatest, all priced just below the $500 mark, which have core clock speeds that are 100MHz higher than standard and memory clock speeds that are up 50MHz above the norm. Cards from MSI, HIS and Gigabyte were represented, and while each of 'em put up a better-than-average fight, the latter card came out on top in nearly every single test. Gigabyte's Super Overclock technology tended to outperform the other OC'ing solutions, but the whole lot managed to show up the non-overclocked alternatives by a good bit. Still, you'll be forced to pay a 25 percent premium for an 11 to 16 percent boost in performance, so these are still probably best for enthusiasts who can't stand to leave a single frame behind. Peep that source if you're in need of more coaching before pulling the trigger either way.
Super PreKernel is the one-touch way to make your Pre or Pre Plus fly (video)
If you're a Pre or Pre Plus owner who has been watching longingly as we've covered the recent spread of overclocking hacks for the thing, but didn't quite feel up to wading through page after page of forum discussions to figure out just how to apply them, the process just got a easier. Like, a whole lot easier. Super PreKernel enables you to go to 550, 600, 720, and even 800MHz with just a single tap. And, when it's time to put on those fake glasses and play Clark Kent, you can drop back down to 500MHz just as easily. It's all thanks to a number of Palm-loving hackers who have put together a truly moving video demonstration of the whole process that's embedded below. We encourage you to enjoy it now, because the selection of copyrighted musical accompaniment for the clip will probably result in it surviving about as long as a bottle of Superman's chosen hair product. Update: We got a note from caj2008 that an updated version has been released, this one fixing a few issues and offering better compatibility with OS 1.4.0, 1.4.1, and 1.4.2.
Nokia N900 overclocked to 1GHz in bid to outrun obsolescence (video)
Given all the Cortex A8 processor clock tweaking going on we admit to being just a little surprised to be reading the first overclocking reports on the eminently hackable N900 only now. Nevertheless, owners are seeing significant speed improvements after updating their stock 600MHz QWERTY sliders with recompiled kernels (no CPU voltage hacks required). Although speeds in excess of 1GHz have been tested (1,050MHz still boots), it looks like 900MHz is the maximum stable clock speed you can expect before the doors rattle off -- but that's only after a weekend of testing. If things continue to go well then you'll see tweaked kernels of various clock speeds released for download soon enough -- something that should keep the device humming right through the commercial launch of MeeGo whether Nokia likes it or not. Check the video after the break and then follow the latest developments in the maemo.org forums by hitting up the source link below.
Palm isn't hot on Pre overclocking, indicates warranties are at risk
You know the hacked Pre firmware releases that have been coming out lately, first for 1.3.5.1 and then recently for 1.4? We tested out that later one and found the results to be good, and indeed one of the creators, caj2008, sent us plenty of data from early testers showing minimal heat gains and battery losses. Still, Palm isn't exactly thanking these guys for their hard work, going so far as to issue a warning: While we appreciate the effort the webOS community has put forth to try and help us along that path, the use of this application is neither endorsed nor recommended by Palm and will likely result in a voided warranty. Frankly you can't be surprised that Palm isn't thrilled about users cranking up the clock multiplier on their phones, nor can you think less of the company for indicating that those doing so might face some warranty issues going forward. And, as we've said before, despite all data that these mods are safe users should exhibit caution before dialing up the megahertz. After all, you wouldn't put a manual controller on your turbo'd car, double the PSI, and then try to get your blown headgasket warrantied... right?
Origin PC stuffs 4.4GHz Core i7-980X, Fermi-based GTX 470 and 480 into Genesis desktop
Hope you didn't just pull the trigger on a new Origin PC Genesis, else you'll be forced to know that your rig was made obsolete in record time. Okay, maybe not obsolete, but there's precisely no doubt that you'd rather be rocking a new Fermi card than whatever you've got now. Right on cue, NVIDIA has launched its latest pair of powerhouse graphics cards, and as of right now, prospective Origin PC buyers can opt for either the GTX 470 or GTX 480 on the Genesis desktop. Better still, you can buy 'em in single, dual or triple SLI configurations, and in case you're down for paying the premium, a 4.4GHz overclocked Core i7-980X Extreme Edition CPU can sit alongside of it (or them).
Pre gets a nasty 800MHz overclock patch for all 1.4 users to enjoy (at one's own risk) (updated)
Looking to harness the real power inside of your Pre (or Pre Plus) -- and you've upgraded to webOS 1.4? If that's the case, you're going to love what a couple of Palm-loving hackers have come up with. Namely, a major overclock kernel patch for the device which boosts the CPU speed from a measly 500MHz all the way up to a finger-searing 800MHz (there's also a more tame 720MHz variation available). The two phone magicians, unixpsycho and caj2008, had previously tapped into the power of the Pre's CPU on webOS 1.3.5 with a small file that can be semi-easily installed using WebOSQuickInstall and a tiny bit of Linux command-line activity, and now it's on for 1.4. So far, it looks like phones being tested with the somewhat risky tweak haven't experienced too much of the normally expected issues (crashes, freezing, phones exploding). Also a surprise is the fact that the creators of the hack say battery life drain is only an additional 2-4 percent hit... though if you're already struggling to make it through a day, this could be the nail in the coffin. We installed the patch on a Verizon Pre Plus, and we definitely observed a noticeable bump in app load times and improved fluidity when working with the phone -- though we've already had one major crash. If you don't mind possibly destroying your phone and must have a faster device right now, you can check out the patch in action and learn how to get it yourself in the video after the break. Update: From the looks of things, that crash we experienced early on is likely due to a bug in webOS 1.4 and not related to the overclock. Actually, we haven't experienced any further problems... in fact, the phone is seeming super speedy, and battery life has not taken a substantial hit, verifying caj2008 and unixpsycho's claims (so far). Someone at Palm should take note -- these guys have some good ideas! [Thanks, G. Scott]
Overclocked Palm Pre is just what the doctor ordered
Is your Palm Pre feeling a bit down? In the dumps? Not as snappy as it used to? Maybe what you need is a megahertz boost! This custom kernel, demonstrated in a video below, comes courtesy of two hackers called unixpsycho and caj2008. One quick install will make your dull and lifeless 1.3.5.1 Pre come alive. Warning: use of this software may "frakk" your Pre if deployed on a 1.4 device. Side effects include reduced battery life and increased pocket warmth. If your Pre develops excessive heat see a doctor immediately -- or just turn it off for awhile. Update: caj2008 dropped us a note to point out that battery life is "not significantly affected" by this patch, but we're still waiting on the FDA ruling on that one. [Thanks, Darren]
Origin PC offers overclocked 4.3GHz Core i7-980X Extreme Edition on Genesis desktop
You know what's better than a stock 3.33GHz Core i7-980X Extreme Edition CPU? Not much, but we're guessing that a 4.3GHz overclocked version of the same chip just might be. If you're thinking the same, and you've got $1,044 to spare in order to find out, upstart gaming rig maker Origin PC has the means to get it to you. The outfit's Genesis desktop can now be ordered with Intel's freshest slab of silicon for $895, or you can snag an extra gigahertz for another $149. We know you'll make the right call.
ATI Radeon HD 5970: world's fastest graphics card confirmed
ATI just announced its latest greatest polygon cruncher on the planet: the previously leaked Radeon HD 5970. The new card card is also one of the first to support Microsoft DirectX 11 and Eyefinity multi-display (driving up to three displays at once for a 7680x1600 maximum resolution) with ripe potential for overclocking thanks to the card's Overdrive technology. Instead of relying upon a single GPU like the already scorching Radeon HD 5870, the 5970 brings a pair of Cypress GPUs linked on a single board by a PCI Express bridge for nearly 5 TeraFLOPS of computer power, or a mind boggling 10 TeraFLOPS when setup in CrossFireX. Naturally, the card's already been put to the test by all the usual benchmarking nerds who praise the card as the undisputed performance leader regardless of game or application. It even manages to keep power consumption in check until you start rolling on the voltage to ramp those clock speeds. As you'd expect then, ATI isn't going to offer any breaks on pricing so you can expect to pay the full $599 suggested retail price when these cards hit shelves today for retail or as part of your new gaming rig bundle.
Origin launches custom gaming rig shop, starts with Genesis and EON18
Does the world really need another high-end gaming PC shop? Looks as if we'll soon find out, as Origin has just launched itself into the mix with a pair of new rigs catering to those with specific (and pricey) demands. Poised to take on the likes of Falcon Northwest, this boutique outfit has ushered itself into the sector with the new Genesis desktop and EON18 laptop. The former gets going at $1,699, and if we're reading this right, Origin allows buyers to select "any chassis on the market, any color and design" and pretty much any other hardware they can dream of. The lappie is an 18.4-inch beast with a 1080p panel, limitless color and design options, twin GeForce GTX 280M GPUs, 8GB of RAM, a trio of HDDs, dual-layer Blu-ray burner and a starting tag of $2,599. So, who's up for celebrating the real end of the recession?
MSI takes the pain, fun out of overclocking with OC Genie
If you thought MSI's obsession with motherboard implants was over after it unveiled Winki to a nearly nonexistent amount of fanfare, think again. The company has just taken the wraps off its latest mobo addition, the OC Genie. In essence, this is the one-touch overclock button that laptop owners have long enjoyed, but for desktops. Right now, the OC Genie is custom built for the company's own P55 motherboard, though it insists that all sorts of mainboards will be supported in due time. If you're curious about the details, you'll have to remain that way for now; all we're told is that activating the module automatically pushes your system to a safe brink within a second, giving even the newbies in attendance the ability to squeeze more from their current rig. In related news, MSI also added yet another model to its growing Classic laptop series, the 17.3-inch CX700, which gets powered by a Core 2 Duo processor, ATI's Mobility Radeon HD4330 GPU and 4GB of RAM.[Via HotHardware]
AMD Phenom II TWKR Black Edition CPU up for auction, sure to fetch a bundle
Remember that AMD Phenom II X4 TWKR processor that we saw overclocked and reviewed just over a fortnight ago? Don't you recall reading and wondering why you were even wasting your time given the scarcity of said chip? It took awhile, but it seems the justification you've been searching for has finally arrived. AMD only manufactured a smattering of these chips in order for select media outlets to showcase the company's potential, and somehow one has found its way onto eBay. Best of all, 100 percent of the proceeds will benefit a charity (Family Eldercare), so you can feel good about spending way, way too much on a slab of silicon. Tap the read link if you care to drive the price up even further (and you know you do).[Thanks, Alex]
Video: AMD's Phenom II X4 TWKR CPU for extreme overclocking lunatics
AMD has recently cooked up a little something they like to call the Phenom II X4 TWKR Black Edition, a hand-picked, limited edition processor that is designed to be overclocked "to the extreme." Currently labeled "Not for Sale," with no serial numbers and only one hundred of these bad boys in existence, just a few lucky folks have got their hands on one, so we've dug up some reviews (and previews) so you can see what the fuss is all about. According to the company, one of these guys could be pushed by 100MHz with air cooling, which doubles to about 200MHz with "extreme cooling." As far as impressions go, the reviewer at Neoseeker quickly decided that the units aren't meant to be overclocked on air only, and that dry ice isn't much better. Hot Hardware says pretty much the same thing. Though they weren't able to test with liquid nitrogen or liquid helium (the only way to get real speed) they did put a Koolance LN2 pot (and about 20lbs of dry ice) to the test for 4.73GHz. For best results, according to Tom's Hardware Guide, bench the processor at -190°C or cooler. But for the real overclocking experience you simply must check out the video of the "world renowned overclockers" K|ngp|n, chew*, and Gomeler as they run the gamut of "extreme overclocking techniques" after the break.

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.
ASUS introduces ROG OC Station for all your on-the-fly overclocking needs
ASUS is doing what it can to bump up its gaming cred a few notches with its Republic of Gamers (ROG) OC Station. The bay-mounted overclock assistant lets you tweak parameters on the fly, even in the middle of a game, without ever having to dive into the BIOS. It's got a 3-inch LCD display, too, for keeping an eye on things or, apparently, showing your pictures in a slideshow. All this power comes at a cost, and not just financially: you're gonna have to give up two 5.25-inch bays to install this bad boy. It also looks like it only works with ROG motherboards, which is gonna limit the market even further. If you are, however, an anxious and willing member of that demographic, we hate to say you're gonna have to wait an undisclosed time before you can pick one up for an undisclosed number of Benjamins.
