Motherboard manufacturers are well-versed in marketing, and over-engineering. And when those two aspects combine, enthusiasts get some really cool feats of hardware overkill. Computex brought us two radical motherboard designs, for example. Gigabyte is at it again, and this time it is showing off the prowess of the company’s power phase design.
Using one of the company’s upcoming Z77 motherboards, Gigabyte was able to deliver 2,000 Watts of power through the LGA 1155 socket--did I mention overkill was the name of the game for this demonstration?
Specifically, Gigabyte paired its Z77X-UP7 motherboard with two Corsair 1200W power supplies and some laboratory gear to measure the power delivery. Using the 32 power phases in its “Ultra Durable 5” design, it was able to draw 300.6A, 300.7A, and 236.3A on three DC load testers. While drawing the total 837.6 amps, Gigabyte used a voltage meter to measure the current at 2.42 volts. Gigabyte then determined that the Z77 motherboard was able to deliver up to 2026.992 watts of power! The company claims that this would be enough power to support 25 Intel Core i7 3770K processors. It would also easily allow you to permanently destroy your processors, and really put that Intel overclocking warranty to the test (heh).
Needless to say, the board has some serious power phase and VRM hardware on board, and should easily handle the most extreme of overclocks. Granted, it is a marketing stunt, but it is a very cool one at that. As one area where motherboard companies heavily market, Gigabyte has quite the record for the others to beat. Here’s hoping that they attempt to break the record so that we can see more interesting tech demos. Maybe ASUS will bring out the Wolverine from the R&D lab, and see what its 40 power phases are really capable of!
What do you think about the Gigabyte claims? Below is the video that the company used to show off the Z77X-UP7 motherboard.

If you've ever wondered if it was worth hitting that 'Report to Microsoft' button after you experienced a BSoD then perhaps this paper from Microsoft Research will enlighten you. After studying reports from 1 million machines that suffered CPU or memory problems, Microsoft broke down all of the data into both failure types and machine types so that they can contrast the results of overclocking laptops and desktops from both major CPU vendors as well as breaking the desktops into ones assembled by a major vendor and ones assembled either by the owner or by a small business.
The basic results are easy to sum up laptops are less likely to crash than desktops, CPU errors are more likely than memory errors and underclocking will indeed make your system less prone to crashes. You are also less likely to see crashes on machines purchased from a major vendor than one assembled yourself or by a small business. Of course the whitebox versus brand name ratings cannot differentiate between someone who just built a PC for the first time and one assembled by a veteran so it is possible that that rating is a little skewed.
As for overclocking, you can see that the results are split between Vendor A and Vendor B as opposed to being labelled Intel and AMD but most readers will be able to make an intelligent guess as to which is which. TACT represents Total Accumulated CPU Time, which does not have to be contiguous and could represent quite a few weeks of ownership if the computer in question is only run for a few hours a day and then shut off. Whether this time was accumulated quickly or spaced out, it shows that overclocking either vendors chips will have a significant impact on the stability of your system. Again, there is no division into experienced overclockers and neophytes nor between those who overclock manually or with software or hardware included with the motherboard they chose. Even still the impact on stability is very large regardless of vendor and if you crash once you can be almost guaranteed to crash a second and third time. The table only focuses on the first three crashes as by the time that third crash occurs it is obvious they will continue until something is changed. Check out the abstract here or just head straight to the bottom of that page for the full PDF of results.
"Researchers working at Microsoft have analyzed the crash data sent back to Redmond from over a million PCs. You might think that research data on PC component failure rates would be abundant given how long these devices have been in-market and the sophisticated data analytics applied to the server market — but you’d be wrong. According to the authors, this study is one of the first to focus on consumer systems rather than datacenter deployments."

Introduction and Features
Courtesy of ASUS
ASUS continues to optimize their hardware for the overclocking and PC gaming crowds, but they are also catering to a niche audience looking for ultra stable and durable PC components. ASUS's Sabertooth X79 motherboard is their one of their latest products to bear the TUF series label and sport customized hardware and thermal components as well as a desert camo color scheme to complete the military look. This $329 motherboard comes with a five-year warranty, digital power management system, rugged chokes, solid capacitors, and MOSFETs that have been certified through third party, military-grade testing.

The Sabertooth X79 also comes with a host of other features to improve SSD caching and give users quad GPU support for CrossfireX and SLI graphics card configurations. This board also includes a unique UEFI BIOS and natively supports 2TB hard drives with 64-bit operating systems. The USB BIOS "Flashback" feature also helps new users update their motherboard BIOS without entering the BIOS. ASUS states that users can use any USB storage device with the latest BIOS, push the BIOS button located on the back I/O panel for three seconds, and the board will automatically update the BIOS using standby power. Very cool!

The back I/O panel on the Sabertooth X79 is no slouch either as it gives users a healthy amount of USB 2.0, USB 3.0, and eSATA 6GB/s ports for greater performance and expandability options. They also added a small fan over the back I/O panel as part of their "TUF Thermal Armor" feature that will help cool and exhaust heat from ther motherboard out the back of the chassis. Let's move on to the rest of the Saberbooth X79's features where we will get our first out-of-the-box look at this motherboard.

G.Skill will host an overclocking event at Computex 2012 with seven overclockers in an attempt to break world overclocking records. The company is teaming up with ASUS, EVGA, Gigabyte, and MSI for the event, which will be held in Taipei, Taiwan from June 5th to June 9th 2012.
Enthusiast RAM manufacturer G.Skill has announced that they will be hosting an overclocking event at Computex 2012 in Taiwan. The company is partnering up with motherboard manufacturers ASUS, EVGA, Gigabyte, and MSI who will provide several high end motherboards for the overclocking invitational.
G.Skill has further invited seven professional overclockers to attend the event and try to break world records for processors and DDR3 memory using LN2 and a combination of high end motherboards, graphics cards, and G.Skill’s DDR3 RAM. The overclockers in question are Elmor, Fred Yama, Hiwa, Young Pro, Kingpin, HiCookie, and Dinos22. HiCookie was covered by us recently when he pushed a Core i7 3770K to 7.03 GHz and DDR3 memory to an impressive 3.28 GHz. The G.Skill event will push for even higher overlcocks.
The overclocking event will run from June 5th, 2012 to June 9th, 2012 from 11am to 5pm. It will be located at Computex 2012 in the Nangang Exhibition Hall at booth L0118. The event schedule will be as follows:
|Date||Motherboard Brand||Platform||G.Skill Overclockers||Motherboard Overclockers|
|June 5th||MSI||Z77 & X79||
Young Pro (Australia)
Young Pro (Australia)
|Fred Yama (Japan)|
|June 7th||EVGA||Z77 & X79||
Young Pro (Australia)
Young Pro (Australia)
As G.Skill's first overclocking invitational, they will need to push hard for success, and they made sure to have the best record-breaking chance possible by inviting some of the world's best overclockers. As a personal fan of G.Skill, I'm rooting for them to break the RAM overclocking record!

Tagged: asus, maximus v gene, p8z77-V deluxe, overclocking, smackdown
Earlier this week, we and several other sites reported that a Gigabyte Z77X-UD3H motherboard managed to take the Ivy Bridge i7-3770 with a single core enabled all the way to 7.03GHz and ASUS would like to know what all the fuss is about. It seems that on January the 5th, ASUS took the i7-3770 to 7.06GHz on a P8Z77-V Deluxe which not only beats Gigabyte's overclock but did so long enough ago we needed to be reminded of it.
That was not even the best overclock that ASUS managed, the tiny Maximus V Gene could support a speed of 7.07GHz. That speed was hit yesterday by Andre Yang and seems to demonstrate that for extreme overclockers it is ASUS' Z77 boards which you should be counting on.
Hopefully this little correction will start an overclocking war between the two manufacturers, as both host events for overclockers as does MSI who have not chimed in to this contest yet. LN cooling is not for the faint of heart but it is what you need to practice in order to compete at this level. Gigabyte does seem to have one record which does still stand, DDR3-3280 MHz is quite spectacular.
ASUS master overclocker Andre Yang has managed another benchmarking world record, once more using the Intel Z77-based ROG Maximus V GENE mATX. Utilizing a quad-core/eight threaded Intel i7-3770 Ivy Bridge processor, Andre was able to overclock the CPU to an impressive milestone frequency of 7074.7MHz, again breaking the fabled 7GHz processor threshold and overtaking the previous record of 7.06GHz ( which was previously set and held by ASUS with the P8Z77-V Deluxe ). The CPU multiplier and BCLK were set to 112.69 x 63. The Maximus V GENE had 4GB of G.Skill DDR3 RAM, clocked to 1197.8MHz. The graphics card used was an ASUS GeForce GTX 680, set to 705MHz/3004MHz. Keep in mind quad-core and eight-threaded overclocking presents a much tougher challenge than more traditional single-core and double-threaded tuning in terms of stability and consistency, making the feat even more impressive.

Tagged: hyperthreading, Intel, overclocking, fud
In the past there have been two arguments against using Intel's HyperThreading to create two threads per core. The first is specific to overclockers who found that previous generations of Pentium and Core architecture chips could remain stable when pushed to higher frequencies when they disabled HyperThreading. There is still a lot of testing to be done on Ivy Bridge overclocking before a definitive answer is found for this generation of chips, which may fall victim to power issues before HyperThreading becomes a major limiter.
The second issue is more serious and deals with the fact that in some cases enabling HyperThreading reduces the total performance of the chip on certain, usually single threaded, applications and by disabling it you will see performance improvements from your processor. SemiAccurate felt that this needed to be revisited in light of the release of Ivy Bridge and so took an i7-3770K through a battery of 7 tests once with HyperThreading enabled and once without, including a run through CineBench with multithreaded processing disabled. Drop by to see if there is any noticeable benefit to disabling HyperThreading on this generation of Intel processor.
Yes, that was 11 years ago
"We decided to explore the effects of Hyper-Threading on the performance of the Ivy Bridge based Core i7-3770K by running our CPU benchmarking suite on it twice. Once with Hyper-Threading enabled, and once with Hyper-Threading disabled. As such we set-up our results table to look for applications that perform better with Hyper-Threading disabled, rather than enabled."

Tagged: tDCS, overclocking, DIY, brain, augmentation
The new Extreme Tech (RIP ET Classic) recently ran an article that talks about turbo boosting, overclocking goodness, but with a twist. Instead of the typical CPU or GPU hardware, the article talks about overclocking some wetware in the form of the human brain. More specifically, a DIY kit called the GoFlow is in the works to enable affordable tDCS, or transcranial direct-current stimulation, to stimulate the brain into a "state of flow" enabling quicker learning and faster response times.
The GoFlow β1 will be a $99 do it yourself tDCS kit that will direct you in placing electrodes on the appropriate areas of your scalp and then pumping some direct current from a 9V battery at 2 milliamps through your brain, enticing the neurons into a state of flow. This makes them more malleable to creating new pathways and increasing learning speed as well as allowing them to fire more rapidly, bolstering thought processes. The kit, which is not available for purchase yet, will not require any knowledge of soldering, and will be housed a plastic case along with wires, schematics, and a potentiometer to dial in the right amount of power.
The company behind the GoFlow β1 has further referenced cases of successful tDCS short term testing including tests of UAV Drone pilots and professional gamers all learning their respective trades more quickly than the average. Extremetech also mentions that tDCS can have therapeutic effects for people effected by Parkinson’s or post stoke motor dysfunction.
Right now, the kit is still in the works, but interested users can sign up to be notified when it becomes available on their website. At $99, is this something work a shot, or do you prefer not to void the warranty on your brain? (heh) Personally, statements such as "our tDCS kit is the shit" and "get one of the first β1's and will help us develop β2" on the webstie are not exactly instilling confidence to me, but if you're big into the early adopter adventure, GoFlow may have something for you to test.

It would be quite the feat to find a case to contain the system below, with four HD7970s powered by two 1200W PSUs plus other assorted components, not to mention the heat this system will produce. Not even the ASUS MARS 2 in SLI can keep up with this monstrosity and the scaling from a pair of HD7970s is rather impressive as in the past adding the third and fourth card did not lead to large gains. The Core i7-3960X @ 4.8GHz simply can't keep up with the GPUs, implying that this system could actually be more impressive. If you want to see $2200+ of GPUs in action then head to OC3D.
"In combination with ASUS we're rerunning our Quadfire HD7970 test with the benefit of overclocking. Roll up, roll up."

Tagged: tuning plan, processors, overvolting, overclocking, cpu
Intel relatively recently started producing unlocked "K" series processors that enabled easy overclocking by way of increasing the multiplier. This is a feature that was traditionally reserved for the thousand dollar Extreme Edition products. AMD then followed suit with its own line of "K" series APUs (despite having FX and Black Edition branding already, but that's another story). Well, it is now Intel's turn to leap frog AMD who has traditionally been the overclocker friendly company. Yesterday Intel launched a new pilot program that overclockers and enthusiasts are sure to enjoy. The new Performance Tuning Protection Plan is a program aimed at users of "K" and "X" (unlocked and extreme edition) processors who are adventurous enough to overclock and overvolt their chips to wrangle the best possible performance from them. While the company has stressed that they still do not officially endorse overclocking or otherwise running their CPUs out of Intel specifications, the Performance Tuning Protection Plan is an additional service that can be added in addition to (though seperate from) the existing warranty wherein Intel will furnish a free replacement processor to any users that (unintentionally) damage their processors as a result of overclocking or increasing the voltage. Read on for more details.
The new Performance Tuning Protection Plan will be offered directly from Intel as well as various resellers and can be purchased for any of Intel's K series, X series, or Socket 2011 processors. Only one plan can be applied per processor, and once the CPU has been replaced with a replacement processor through the plan, the insurance does not "roll over" to the replacement part. This means that a second chance is all you get. If the replacement CPU fails as a result of overclocking or overvolting you're out of luck. The Protection Plan is further an additional expense that will applied in addition to the standard 3 year manufacturer's warranty. It only covers damage caused by running the processor out of spec. After purchasing the processor, users can buy the protection plan for a one time fee, and it will kick in within approximately 30 days of buying the plan. Intel says the delay is caused by the time needed for the various plan supporting databases to sync up and for payment to clear.
Prices vary depending on which processor you want to protect with the plan. The Performance Tuning Protection Plan pricing for currently supported processors is listed in the chart below.
|Processor||Price (USD) per CPU|
|Core i5 2500K||$20|
|Core i7 2600K||$25|
|Core i7 2700K||$25|
|Core i7 3930K||$35|
|Core i7 3960X||$35|
Intel is currently offering the new overclocking insurance for a limited time-- a six month trial run to be more specific. Starting January 18th, the company will begin selling the plan directly to customers on their website as well as through several resellers. Initially these resellers include CyberPower, Canada Computers and Electronics, Scan Computers, and Altech Computers. On February 13th, Intel will add additional resellers to the list. The pilot phase will last for six months; after which the company will "decide whether or not to proceed" with the plan. Obviously there is a slight risk for early adopters that after buying the plan, Intel will discontinue it at the six month mark; however, there is also a solid opportunity to overclock the heck out of the chips and have an official safety net for the next few months at the least. Are you running an unlocked processor, and if so will you be checking out the Tuning Protection Plan?
