During AMD’s Ryzen launch event a team of professional overclockers took the stage to see just how far they could push the top Zen-based processor. Using a bit of LN2 (liquid nitrogen) and a lot of voltage, the overclocking team was able to hit an impressive 5.20 GHz with all eight cores (16 threads) enabled!
In addition to the exotic LN2 cooling, the Ryzen 7 1800X needed 1.875 volts to hit 5.20 GHz. That 5.20 GHz was achieved by setting the base clock at 137.78 MHz and the multiplier at 37.75. Using these settings, the chip was even stable enough to benchmark with a score of 2,363 on Cinebench R15’s multi-threaded test.
According to information from AMD, a stock Ryzen 7 1800X comes clocked at 3.6 GHz base and up to 4 GHz boost (XFR can go higher depending on HSF) and is able to score 1,619 in Cinebench. The 30% overclock to 5.20 GHz got the overclockers an approximately 45% higher CInebench score.
Further, later in the overclocking event, they managed to break a Cinebench world record of 2,445 points by achieving a score of 2,449 (it is not clear what clockspeed this was at). Not bad for a brand-new processor!
The overclocking results are certainly impressive, and suggest that Ryzen may be a decent overclocker so long as you have the cooling setup to get it there (the amount of voltage needed is a bit worrying though heh). Interestingly, HWBot shows a Core i7 6900K (also 8C/16T) hitting 5.22 GHz and scoring 2,146 in CInebench R15. That Ryzen can hit similar numbers with all cores and threads turned on is promising.
I am looking forward to seeing what people are able to hit on air and water cooling and if XFR will work as intended and get most of the way to a manual overclock without the effort of manually overclocking. I am also curious how the power phases and overclocking performance will stack up on motherboards using the B350 versus X370 chipsets. With the eight core chips able to hit 5.2, I expect the upcoming six core Ryzen 5 and four core Ryzen 3 processors to clock even higher which would certainly help gaming performance for budget builds!

What happens when you unlock an AMD Fury to have the Compute Units of a Fury X, and then overclock the snot out of it using LN2? User Xtreme Addict in the HWBot forums has created a comprehensive guide to do just this, and the results are incredible.
Not for the faint of heart (image credit: Xtreme Addict)
"The steps include unlocking the Compute Units to enable Fury X grade performance, enabling the hotwire soldering pads, a 0.95v Rail mod, and of course the trimpot/hotwire VGPU, VMEM, VPLL (VDDCI) mods.
The result? A GPU frequency of 1450 MHz and HBM frequency of 1000 MHz. For the HBM that's a 100% overclock."
Beginning with a stock ASUS R9 Fury STRIX card Xtreme Addict performed some surgery to fully unlock the voltage, and unlocked the Compute Units using a tool from this Overclock.net thread.
The results? Staggering. HBM at 1000 MHz is double the rate of the stock Fury X, and a GPU core of 1450 MHz is a 400 MHz increase. So what kind of performance did this heavily overclocked card achieve?
"The performance goes up from 6237 points at default to 6756 after unlocking the CUs, then 8121 points after overclock on air cooling, to eventually end up at 9634 points when fully unleashed with liquid nitrogen."
Apparently they were able to push the card even further, ending up with a whopping 10033 score in 3DMark Fire Strike Extreme.
While this method is far too extreme for 99% of enthusiasts, the idea of unlocking a retail Fury to the level of a Fury X through software/BIOS mods is much more accessible, as is the possibility of reaching much higher clocks through advanced cooling methods.
Unfortunately, if reading through this makes you want to run out and grab one of these STRIX cards availability is still limited. Hopefully supply catches up to demand in the near future.

Tagged: Richland, overclocking, LN2, APU, amd, a10-6800k
A Finnish overclocker known as “The Stilt” recently pushed an AMD Richland APU to 8.2GHz using liquid nitrogen. In doing so, The Stilt broke the world record for APU overclocking, besting his previous overclock attempt.
Specifically, the chip was a retail version of the AMD A10-6800K “Richland” APU. It was overclocked to 8203.01 MHz with a 130.21 MHz base clock and 63x multiplier. Even more impressive is that The Stilt managed the overclock with less voltage -- 1.968 volts -- than his earlier (and lower) overclock. For comparison, the earlier overclock brought the A10-6800K to 8000.48 MHz using 2.008 volts.
The system used to overclock the APU included an ASUS F2A85-V Pro motherboard, 8GB of AMD DDR3 Performance memory, and a Radeon HD 7750 graphics card. The overclocker used liquid nitrogen to cool the APU while the GPU was left at stock settings and with its default air cooler. The RAM was overclocked to 2083.6 MHz with 10-11-10-27 timings.
In all, it is an impressive overclock considering all four CPU cores were left enabled! More details along with validation of the overclock can be found over at HWBot.

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: LN2, Kingpin, F1 Extreme Dark Cooling Pot
Kingpin's F1 Extreme Dark Cooling Pot is not for the faint of heart or for that matter for the lazy. The price you pay for exotic cooling is evaporation which unfortunately is also the key to how this type of cooling works so well. You will constantly need to top off the Extreme Dark Cooling Pot with LN2 but for the extreme overclocker that is just part of the drill. OC3D shows off the new pot and adds a small tutorial on setting up your CPU and motherboard for this type of cooling as insulation is important to target the heatspreader on the CPU as well as ensuring that condensation does not interfere with other components near the CPU socket. If you need a cool looking new pot or are interested in just how this type of cooling is done then head to Overclockers.com and take a look at Kingpin's latest product.
"Overclockers have always been a bit extreme – we take hardware many people are perfectly satisfied with and then push every last MHz we can out of it within our cooling limits. Some choose air cooling, some choose water cooling. There are a few brave souls that use water chillers, but mostly those are benching operations only."

Tagged: ROG, overclocking, LN2, HD 7970, asus, amd
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.

Tagged: superpi, overclocking, LN2, llano, APU, amd, a8-3850
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.

If you have heard the term "bottleneck" when you have been describing your dream PC on the forums and wonder why people are referring to your CPU as the weak link when your GPU is so powerful that the CPU shouldn't have to do anything? Unfortunately it is not that simple and a powerful GPU can be held back by a CPU that can't keep up with it. Drop by Funky Kit for a look at bottlenecking by a serious overclocker who is quite used to overpowering CPUs.
"In the DIY computer world a lot of people are concerned about a video card (GPU) "bottlenecking" on a given CPU, or a given CPU bottlenecking a GPU. In this article I will explain what it is that they are talking about, as well as discussing whether or not it's worth being worried about. First off is the answer to the question "What is this bottlenecking you speak of?!"
