The HD 7970 is nice but not nice enough for Kyle and the gang over at [H]ard|OCP who started overclocking the card as soon as they polished off the review at default settings. If they were hoping for a challenge, the card was a bit of a disappointment as they cranked the overdrive frequencies to their maximums of 1125MHz GPU and 1575MHz RAM only to find that the card remained 100% stable. Discouraged but not defeated, they reached out to Sapphire for a custom version of the TRIXX Utility, which allows more control over voltages as well as significantly higher clock speeds. The resulting tests pegged the card at 1.26GHz GPU and 1725MHz for the memory, not too shabby for air cooling!
"We overclock the Radeon HD 7970 in Overdrive and show you what 1.125GHz of performance looks like. Then, we go to the edge and overclock the voltage and take this GPU past 1.2GHz for stellar overclocked gaming performance. We compare this to an overclocked GeForce GTX 580 and see how performance stacks up."

ASUS' Republic of Gamers is off to an incredible start this year with the release of the HD7970, though there are always those who cannot leave their GPUs at reference speeds. For instance Shamino, who is not just a ranger in the Ultima series, but is also now the ultimate champion of extreme GPU overclocking. Taking a brand new HD 7970, removing the stock cooling and replacing it with LN2 cooling has netted him the record for single GPU performance. He scored 15,063 on 3DMark11 and 54,725 on 3DMark Vantage with an 84% overclock, the GPU was running at 1700MHz when he hit the record.
It can certainly be hard to get into a game when you need to constantly replace the evapourating LN2 cooling the GPU but for overclocking purposes you simply cannot beat the cooling ability of LN2. His record may not stand for long, they never do in OCing competiton, but for now he is king of the ring and is looking to move onto bigger and better things ... in this case a quad-CrossFire system which he intends to use to take the grand title of fastest graphics performance on the planet.
Introduction, Features, Technical Specifications
Performance CPU coolers have been saturating the market in bunches this year, and Thermaltake added the FrioOCK to the fray to compete against other high-end heatsinks geared toward overclockers and power PC users. We wasted no time installing the FrioOCK in our LGA 1155 teset bench to see how it stacks up against other extreme air-cooled CPU coolers!
The FrioOCK is a universal CPU cooler that supports a variety of socket types from Intel (LGA1366, LGA1155, LGA1156, and LGA775) and AMD (AM3, AM2+, AM2). This heatsink uses a dual-tower design with six copper heatpipes to dissipate heat from the processor. The unit also sports two 130mm fans in a push-pull configuration to wisk heat away from the CPU.

Perhaps not everybody has fond memories of overclocking past architectures with jumpers on motherboards and needing to be able to do math to determine what overclock you want and more importantly if it took or if the system bailed back to default clocks. Those days are behind us now, as the BIOS becomes the UEFI and you can use a mouse to affect changes on your system timings. Bulldozer does offer some complexity to those looking for a challenge but for most it is the unlocked Sandy Bridge processors that are the go to chip for overclockers. According to information VR-Zone picked up at IDF, overclocking the upcoming families of processors will be even easier. Intel has changed quite a bit over recent years, from the extreme of locking all their processor frequencies to making it easy for the enthusiast to push their CPU beyond design specs.
"Ivy Bridge CPUs decouple the main clock finally, following what the coming Sandy Bridge - E Socket 2011 is also implementing. Now, you can overclock the cores and memory without worrying about affecting the I/O and PCIe clocks. But then comes the more interesting piece news. A year later, in early 2013, the pinnacle of Intel's 22 nm process show off, the initial Haswell processor, is expected to go another step further, where CPU core, GPU, memory, PCI and DMI ratios are all set independently here, on top of fine grain BCLK base clock available within the Lynx Point chipset."

Although the record was set a few weeks ago, we didn't have a chance to see it until today. A group of overclockers pushed a new AMD FX 8150 Bulldozer chip up to 8.429GHz which breaks the old record for highest CPU frequency set with a Celeron 352. You need liquid helium to manage this so do not expect to see that kind of result with air cooling. If you check out [H]ard|OCP 's video coverage you will see the performance of water, phase change and LN2 with the FX8150, though you probably know about it already since you have watched Ryan's coverage.
"If you are wondering how well the new AMD FX CPU will overclock, you are not alone. AMD let us have some behind-the-scenes access a couple of weeks ago and is now allowing us to show off the results. We shot a lot of video and show you AMD FX overclocking on water, phase change, and liquid nitrogen."

There is a sub-culture in the computing world that is more or less analogous to the world of NHRA drag racing: liquid nitrogen overclocking. And if you are really serious, liquid helium. During a press event in Austin, TX in August to discuss the upcoming Bulldozer processor, a team of overclockers pushed the new architecture to frequencies well beyond safety and well beyond where they should be. Without giving away the whole story yet, AMD was able to set a new frequency world record...
Sami Mäkinen and his team hit 8.429GHz on liquid nitrogen and liquid helium with a near-production FX processor sample. This bests the reigning record of 8.308 GHz that was hit on a Celeron processor with LN2.
On August 31, an AMD FX processor achieved a frequency of 8.429GHz, a stunning result for a modern, multi-core processor. The record was achieved with several days of preparation and an amazing and inspired run in front of world renowned technology press in Austin, Texas. This frequency bests the prior record of 8.309GHz, and completely blows away any modern desktop processor. Based on our overclocking tests, the AMD FX CPU is a clock eating monster, temporarily able to withstand extreme conditions to achieve amazing speed. Even with more conservative methods, the AMD FX processors, with multiplier unlocked throughout the range, appear to scale with cold. We achieved clock frequencies well above 5GHz using only air or sub-$100 water cooling solutions.
I was in attendance for the event and have to say that group put on a spectacular show and anytime you can play with liquid helium running at near absolute zero temperature, it's worth paying attention! In fact, I put together a video of the event that you can see below and if you haven't participated or seen something of this nature, it is worth checking out!!
Now I need to temper some dreams right now - the chances of you or I reaching these types of clock speeds on the Bulldozer CPUs upon release are pretty close to nil. What was more interesting was the casual overclocking we saw pushing upwards of 4.8+ GHz without breaking a sweat and that is what we will be investigating with our review of the processor later this year.
Update: Here is the screenshot from the official HWBot frequency rankings as well as a different video created by AMD themselves summarizing the event.

Legit Reviews decide that they really wanted to be able to show the overclocking results you can expect from the AMD A8-3850, so they picked up eight of the chips to test each for overclocking ability. There have been examples in the past of chips with a wide variety of overclocking limits which was often decided by the chip revision but not in all cases. The test results show that all but two of the chips hit a stability issue when being pushed beyond 3679.5MHz, so you can take that as the most likely result that your chip will provide. The two outlying chips will be exceptional, in one case in a bad way which you can see in the full review.
"When AMD released the 'Lynx' desktop platform back in June 2011, our motherboard reviewer ran into some bad luck when overclocking the processor. When you get a new platform setup for the very first time you really don't know what to expect and it does take some time to learn all the quirks and nuances of a new processor and motherboard. We recently ordered in six more processors and then overclocked all seven of them to see what the best one would be for our test system!"

One of the favourite features on the high powered graphics cards that Ryan has been reviewing this week is the ability to manually overclock the card while running it. Instead of having to use the built in software tools of the driver to first modify the speed and then running a test cycle it is possible to raise the frequency manually using controls on the card. The changes occur on the fly, without the software first testing to ensure stability which necessitates the presence of a reset button to take you back to stock frequencies. Thanks to Hack a Day you can now see how it is now possible to build your own paddle switch to do the same thing as the high end cards without having to spend the money or reach inside your case. Check out this project which will give you a paddle that not only upclocks your cards memory and GPU separately, it can also reset you back to default speeds if you go too far.
"[Fred] likes to squeeze every cycle possible out of his graphics card. But sometimes pushing the clock speed too high causes corruption. He figured out a way to turn a knob to adjust the clock speed while your applications are still running.
The actuator seen above is a Griffin Powermate 3.0. It’s a USB peripheral which is meant to be used for anything you can imagine. [Fred] uses an AutoHotKey script that he wrote to capture the input from the spinner, process that information, then adjust GPU clock speed in the background. Since the clock on his ATi Radeon 5800 can be adjusted using the AMD GPU clock tool, it’s an easy choice for this application. Now better graphics are at the tips of his fingers. See for yourself in the video after the break."

In a feat of overclocking prowess, the crew over at Akiba have managed to push the AMD Llano A8-3850 to its limits to achieve a Super PI 32M score of 14 minutes and 17.5 seconds at an impressive 4.75GHz. Using a retail A8-3850 APU, a Gigabyte GA-A75-UD4H motherboard, and a spine chilling amount of Liquid Nitrogen, the Japanese overclocking team came very close to breaking the 5GHz barrier.
Just how close did they come? 4.906.1GHz with a base clock of 169.2MHz to be exact, which is mighty impressive. Unfortunately, the APU had to undergo some sever electroshock therapy at 1.792 Volts! Further, the 4.9GHz clock speed was not stable enough for a valid Super PI 32M result; therefore, the necessity to run the benchmark at 4.75GHz.
The extreme cooling ended up causing issues with the motherboard once the team tried to switch out the A8-3850 for the A6-3650; therefore, they swapped in an Asus F1A75-V PRO motherboard. With the A6-3650, they achieved an overclock of 4.186GHz with a base clock of 161MHz and a voltage of 1.428V. The overclockers stated that they regretted having to swap out the Asus board as they believed the Gigabyte board would have allowed them to overclock the A6-3650 APU higher due to that particular motherboard’s ability to adjust voltage higher.
Although they did not break the 5GHz barrier, they were still able to achieve an impressive 69% overclock on the A8-3850 and a 61% overclock on the A6-3650 APU. For comparison, here are PC Perspective’s not-APU-frying overclocking results. At a default clock speed of 2.9 and 2.6 respectively, the A8-3850 and A6-3650 seem to have a good deal of headroom when it comes to bumping up the CPU performance. If you have a good aftermarket cooler, Llano starts to make a bit more sense as 3.2GHz on air and 3.6GHz on water are within reach. How do you feel about Llano?

CITY OF INDUSTRY, CA – July 15, 2010 – Since releasing its Lightning series graphics cards, world-renowned mainboard and graphics card manufacturer MSI has received universal praise from media and gamers alike for their outstanding design, rich use of components, powerful performance, and infinite overclocking potential. With the release of the N580GTX Lightning that follows in the footsteps of previous generation Lightnings, graphics card world records were sure to fall. Overclocking enthusiasts from all over have been running the N580 GTX Lightning with LN2 for some extreme overclocking and once again broke 3DMark 11, 3DMark Vantage, and Unigine Heaven (DX11) single-card, single-core world record scores. These considerable achievements demonstrate once again that only a Lightning can outshine a Lightning!
The triple world record king－N580GTX Lightning
At the beginning of June, US overclocker Splave put the N580GTX Lightning under LN2 cooling and effortlessly set a Unigine Heaven (DX11) single-card, single-core world record with a high score of 2501.6. Then, he topped that score this week with a new world record score of 2562.51! Russia's overclocking ace Smoke also paired a N580GTX Lightning with LN2 for some extreme overclocking as well. In the past few days, with scores of 11,390 and 46,546 respectively, he broke both 3DMark 11 and 3DMark Vantage single card single core world records! This proves the superlative performance of the Lightning series is its best spokesman.
Most advanced design and Military Class II components create a king amongst record-breakers
The N580GTX Lightning, whether in terms of specifications or design, belongs in the highest class of products. The exclusive Power4 power supply architecture and triple overvoltage function strengthens overclocking stability and potential. Additionally, the Extreme OC Function, specifically designed for overclocking, ensures the graphics card can still function normally under extreme overclocking conditions. Adoption of materials has also undergone careful consideration. High quality, second generation Military Class components provide the most stable user experience and optimum durability. In all aspects, MSI Lightning graphics cards demonstrate design and development capability and infinite overclocking potential.
