The AMD Closed Loop System
Closed loop water cooling is not new, but it certainly is a pretty hot topic now. Some of the first units out there had some interesting issues (like internal corrosion clogging everything up), but once those teething problems were solved the closed loop systems turned out to be pretty effective and easy to install. Initially these units had the performance of a top end air cooler, but with a lot lower noise. The latest generation of liquid cooling systems (LCS) is now further improved and provides performance approaching that of larger, more complex cooling systems. These products will not replace exotic systems like phase change, but they provide a lot of cooling in a fairly decent sized package.
Clean lines and graphics give this box a striking look without being tacky.
Last year with the introduction of the AMD FX-8150, AMD decided to create a SKU which not only included the CPU, but also a fairly robust LCS. This unit is based on an Asetek design which features a double wide cooler/reservoir with the push-me/pull-ya fan combination. Other manufacturers offer this particular product under a variety of names, but this is simply an AMD FX branded unit with some small cosmetic changes to differentiate it from other units.
AMD will eventually offer this cooler with the new Vishera based FX-8350 CPU (or at least we assume they will), and we wanted to take this combination out for a spin. In our FX-8350 review we did not hit the overclocking targets that AMD had set. In most literature that we were provided AMD stated that most FX-8350 parts would be able to hit around 5 GHz with some aggressive cooling. In our review I was able to get to around 4.6 GHz max and around 4.5 GHz stable with better than average cooling. The results were not as impressive as we had hoped, but we again did not have a top end cooling solution such as what AMD provides with this particular LCS.
With a brand new LCS in hand, I retested the FX-8350 to see how hard it could be pushed. I also wanted to see how this particular unit performance in terms of thermal properties. The results were quite surprising for me, as this is my first real experience with a LCS.

Gigabyte and Cooler Master have teamed up to host the Winter OC Whiteout overclocking competition. Enthusiasts are encouraged to push their systems as far as possible to achieve the highest 3D benchmark scores. Cooling methods like LN2 and liquid helium are encouraged to break existing records and grab the top spots, with certian hardware restrictions put in place over three classes to reportedly level the playing field.
The overclocking stages are as follows:
- Stage One: 3DMark11 DX11 “No X79” single GPU only
- Stage Two: 3DMark Vantange Dual Core, single GPU only
- Stage Three: Heaven DX11 “Full Out” Any CPU, single GPU only
The stages are fairly self-explanatory. For stage one, users are not allowed to use any Intel X79 hardware (motherboards or processors). In stage two, the limits are that users can only use single or dual core processors. Stage three opens up the system such that you can use any processor and graphics card combination. Further, all three stages are limited to a single graphics card per system.
The contest is being run by HWBot, and overclock submissions need to follow the site’s validation rules. You will need to use a specific HWBot desktop background and submit screenshots of the overclock that include the benchmark score as well as screenshots of CPU-Z’s CPU, Memory, and Mainboard tabs. Also, you will need to include a photo of your computer hardware.
The photos of your computer hardware will also be used for a bonus contest where Gigabyte and Cooler Master will pick ten of the most festive submission photos on January 10th. Those ten photos will be placed on the Gigabyte Tech Column facebook page. The photo from that page receives the most Facebook likes by January 20th will win a bonus prize.
The prizes for the three main overclocking stages include a Gigabyte Z77X-UD4H motherboard and a Cooler Master Seidon 120mm CPU cooler. On the other hand, the bonus prize is a Gigabyte Z77-UD4 motherboard and a Cooler Master Sirus S-5.1 gaming headset.
The contest will run from December 21st to January 20th, 2013. You can find more information over at the HWBot contest page.

Tagged: amd, APU, A10 5800K, overclocking, LN2
It is worth remembering the AMD A10 5800K for a number of reasons, a mere $120 gets you not only a relatively decent CPU, the onboard 7660D will function quite effectively for streaming HD video or light gaming. As well it is unlocked which means you can overclock both processors; MadShrimps hit 1186MHz on the 7660D from the 800MHz base clock and could easily reach 4.5GHz on the CPU cores. Make sure to pick up memory of 1600MHz or more to feed that GPU and don't expect to see these overclocks on air, but perhaps a good liquid cooler might get you close to some of these scores. If you know someone who needs a new multipurpose PC and looks at you blankly when you ask if it needs to be able to play Crysis, you could do worse than AMD's A10 5800K.
"Who hasn't heard about the following phrase? The Future is Fusion! Unless you have been living under a rock for the last years, this AMD marketing slogan was pretty much everywhere. AMD wanted to create a platform that was mainly very affordable, where a dedicated graphics card was not a must, while being power efficient, especially for the mobile market and up to the task to satisfy our multimedia, digital desires/needs. One option already existed in the form of an integrated graphic chips solutions on the motherboard. However the latter had non-conforming performance for todays standards. This all lead to the creation of the APU, Accelerated Processing Unit. The first steps to make Fusion a reality. The FM1 socket Llano CPUs was AMD's first succesful try in this new market. As usual the competition caught up, so time for a new revision of the AMD APU. Hello world this is platform Virgo calling... Time to have a look at AMD's latest Trinity socket FM2 APU."

Tagged: Raspberry Pi, overclocking, arm
The Raspberry Pi has proved a popular – if difficult to get a hold of – low-cost computer. The Pi is powered by a Broadcom BCM2835 ARM system on a chip that features a VideoCore IV GPU and ARM1176JZFS CPU core. By default, the processor runs at 700MHz, but enthusiasts put it through its paces and found there to be more than a bit of headroom. Unfortunately, if your particular chip required a bit of extra voltage to run at higher frequencies, it would mean voiding your warranty in order to get the extra performance – until now, that is.
In a bit of good news for overclockers, the Raspberry Pi Foundation has announced that official overclocking will now be supported even when the processor has been over-volted. In the raspi-config file, you will be able to choose from one of five overclocking presets where the highest overclock will run the processor at 1GHz.
Interestingly, the overclocked frequency is managed by the cpufreq driver and can be dynamically adjusted. The processor will run at up to the frequency defined in your chosen preset as long as the temperature of the chip does not reach 85 °C. Also, the overclocked frequencies will only be applied when the SoC is under load. When idling, it will happily use less power by turning the clockspeed down. Further, when applying the higher clocks, you are also adjusting the GPU Core, SDRAM, and system bus speed.
When combined with other software fixes (below), the Raspberry Pi Foundation is claiming various performance improvements. According to the site, Linux benchmark nbench reports 52% better integer performance, 64% increased floating point performance, and a 55% improvement in memory.
Left: default clockspeeds, right: 1GHz overclock
Should your particular Raspberry Pi not boot after applying a higher overclocking preset, you can hold down the Shift key during boot to force the Raspberry Pi to revert to default clockspeeds. Then, you can back down to the next-highest preset to see if the Raspberry Pi is capable of running at that (though it would be a better idea to start at the lowest preset and work your way up). The Raspberry Pi Foundation recommends playing through a bit of Quake 3 as it is a good indicator of a stable overclock.
In addition to the new turbo mode, a fix has been applied to the USB driver to reduce the USB interrupt rate, which improves performance approximately 10%. Because even the LAN port is on the USB bus, reducing CPU load should help a lot in freeing up the limited resources of the ARM processor for other tasks. If you have Wi-Fi devices based on the RTL8188CUS chipset or is otherwise supported by Linux, it should now work with the Raspberry Pi out of the box.
In order to get all of the above improvements (among a couple of other minor tweaks), you can run the following command to update to the latest image:
“sudo apt-get update && sudo apt-get upgrade”
It’s nice to see continued support for the Raspberry Pi, and the ‘free’ overclocking performance is always a plus!

Tagged: Z77, ultra durable 5, power phase, overclocking, Gigabyte Z77X-UP7, gigabyte
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.

Tagged: microsoft, overclocking
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.
