Update 9/27 @ 5:10pm: Added a link to Anandtech's discussion of Bristol Ridge. It was mentioned in the post, but I forgot to add the link itself when I transfered it to the site. The text is the same, though.
While Zen is nearing release, AMD has launched the AM4 platform with updated APUs. They will be based on an updated Excavator architecture, which we discussed during the Carrizo launch in mid-2015. Carrizo came about when AMD decided to focus heavily on the 15W and 35W power targets, giving the best possible experience for that huge market of laptops, in the tasks that those devices usually encounter, such as light gaming and media consumption.

Bristol Ridge, instead, focuses on the 35W and 65W thermal points. This will be targeted more at OEMs who want to release higher-performance products in the holiday time-frame, although consumers can purchase it directly, according to Anandtech, later in the year. I'm guessing it won't be pushed too heavily to DIY users, though, because they know that those users know Zen is coming.
It turns out that overclockers already have their hands on it, though, and it seems to take a fairly high frequency. NAMEGT, from South Korea, uploaded a CPU-Z screenshot to HWBot that shows the 28nm, quad-core part clocked at 4.8 GHz. The included images claim that this was achieved on air, using AMD's new stock “Wraith” cooler.

Corsair and MSI have teamed up once again to produce a liquid-cooled edition of the latest NVIDIA GPU, with the GTX 1080 receiving the same treatment these two gave to the Hydro GFX version of GTX 980 Ti last year.
“The CORSAIR Hydro GFX GTX 1080 brings all the benefits of liquid cooling to the GeForce GTX 1080, boasting an integrated CORSAIR Hydro Series H55 cooler that draws heat from the GPU via a micro-fin copper base cold plate and dissipates it efficiently using a 120mm high-surface area radiator. A pre-installed low-noise LED-lit 120mm fan ensures steady, reliable air-flow, keeping GPU temperatures down and clock speeds high.
With a low-profile PCB and pre-fitted, fully-sealed liquid cooler, the Hydro GFX GTX 1080 is simple and easy to install. Just fit the card into a PCI-E 3.0 x16 slot, mount the radiator and enjoy low maintenance liquid cooling for the lifetime of the card.”
Naturally, with an integrated closed-loop liquid cooler this GTX 1080 won't be relegated to stock speeds out of the box, though Corsair leaves this up to the user. The card offers three performance modes which allow users to choose between lower noise and higher performance. Silent Mode leaves the GTX 1080 at stock settings (1733 MHz Boost), Gaming Mode increases the Boost clock to 1822 MHz, and OC Mode increases this slightly to 1847 MHz (while increasing memory speed in this mode as well).
This liquid-cooled version will provide higher sustained clocks

Tagged: amd, asus, STRIX R9 380X DirectCU II OC, overclock
Out of the box the ASUS STRIX R9 380X OC has a top GPU speed of 1030MHz and memory at 5.7GHz, enough to outperform a stock GTX 960 4GB at 1440p but not enough to provide satisfactory performance at that resolution. After spending some time with the card, [H]ard|OCP determined that the best overclock they could coax out of this particular GPU was 1175MHz and 6.5GHz, so they set about testing the performance at 1440p again. To make it fair they also overclocked their STRIX GTX 960 OC 4GB to 1527MHz and 8GHz. Read the full review for the detailed results, you will see that overclocking your 380X does really increase the value you get for your money.
"We take the new ASUS STRIX R9 380X DirectCU II OC based on AMD's new Radeon R9 380X GPU and overclock this video card to its highest potential. We'll compare performance in six games, including Fallout 4, to a highly overclocked ASUS GeForce GTX 960 4GB video card and find out who dominates 1440p gaming."

An author called "2PKAQWTUQM2Q7DJG" (likely not a real name) has published a fascinating little article today on his/her Wordpress blog entitled, "Overclocking Tools for NVIDIA GPUs Suck. I Made My Own". What it contains is a full account of the process of creating an overclocking tool beyond the constraints of common utilities such as MSI Afterburner.
By probing MSI's OC utility using Ollydbg (an x86 "assembler level analysing debugger") the author was able to track down how Afterburner was working.
“nvapi.dll” definitely gets loaded here using LoadLibrary/GetModuleHandle. We’re on the right track. Now where exactly is that lib used? ... That’s simple, with the program running and the realtime graph disabled (it polls NvAPI constantly adding noise to the mass of API calls). we place a memory breakpoint on the .Text memory segment of the NVapi.dll inside MSI Afterburner’s process... Then we set the sliders in the MSI tool to get some negligible GPU underclock and hit the “apply” button. It breaks inside NvAPI… magic!
After further explaining the process and his/her source code for an overclocking utility, the user goes on to show the finished product in the form of a command line utility.
There is a link to the finished version of this utility at the end of the article, as well as the entire process with all source code. It makes for an interesting read (even for the painfully inept at programming, such as myself), and the provided link to download this mysterious overclocking utility (disguised as a JPG image file, no less) makes it both tempting and a little dubious. Does this really allow overclocking any NVIDIA GPU, including mobile? What could be the harm in trying?? In all seriousness however since some of what was seemingly uncovered in the article is no doubt proprietary, how long will this information be available?
It would probably be wise to follow the link to the Wordpress page ASAP!

ASUS has annouced a new STRIX edition of the GeForce GTX 980 Ti, and this is one massive card in not only size (measuring 12" x 6" x 1.57") but in potential performance as well.
First off, there is the new DirectCU III cooler, which offers 3 fans and a much larger overall design than that of the existing GTX 980 STRIX card. And there's good reason for the added cooling capacity: this card has one hefty overclock for a GTX 980 Ti, with a 1216 MHz Base and a whopping 1317 MHz Boost clock in "OC mode". The card's default mode is still quite a bit over reference with 1190 MHz Base and 1291 MHz Boost clocks (a reference 980 Ti has a Base of 1000 MHz and Boost clock of 1075 MHz). Memory with the STRIX 980 Ti is also overclocked, with 7200 MHz GDDR5 in both modes.
Features for this new card from ASUS:
- 1317MHz GPU boost clock in OC mode with 7200MHz factory-overclocked memory speed for outstanding gaming experience
- DirectCU III with Patented Triple Wing-Blade 0dB Fan Design delivers maximum air flow with 30% cooler and 3X quieter performance
- AUTO-EXTREME Technology with 12+2 phase Super Alloy Power II delivers premium aerospace-grade quality and reliability
- Pulsating STRIX LED makes a statement while adding style to your system
- STRIX GPU-Fortifier relieves physical stress around the GPU in order to protect it
- GPU Tweak II with Xsplit Gamecaster provides intuitive performance tweaking and lets you stream your gameplay instantly
The new DirectCU III cooler
The 0dB fans (zero-RPM mode under less demanding workloads) are back with a new "wing-blade" design that promises greater static pressure. Power delivery is also improved with the 14-phase "Super Alloy Power II" components, which ASUS claims will provide 50% cooler thermals while reducing "component buzzing" by up to 2x under load.
The previous DirectCU II cooler from the STRIX GTX 980
The new ASUS STRIX GTX 980 Ti Gaming card hasn't shown up on amazon yet, but it should be available soon for what I would expect to be around $699.
Quiet, Efficient Gaming
The last few weeks have been dominated by talk about the memory controller of the Maxwell based GTX 970. There are some very strong opinions about that particular issue, and certainly NVIDIA was remiss on actually informing consumers about how it handles the memory functionality of that particular product. While that debate rages, we have somewhat lost track of other products in the Maxwell range. The GTX 960 was released during this particular firestorm and, while it also shared the outstanding power/performance qualities of the Maxwell architecture, it is considered a little overpriced when compared to other cards in its price class in terms of performance.
It is easy to forget that the original Maxwell based product to hit shelves was the GTX 750 series of cards. They were released a year ago to some very interesting reviews. The board is one of the first mainstream cards in recent memory to have a power draw that is under 75 watts, but can still play games with good quality settings at 1080P resolutions. Ryan covered this very well and it turned out to be a perfect gaming card for many pre-built systems that do not have extra power connectors (or a power supply that can support 125+ watt graphics cards). These are relatively inexpensive cards and very easy to install, producing a big jump in performance as compared to the integrated graphics components of modern CPUs and APUs.
The GTX 750 and GTX 750 Ti have proven to be popular cards due to their overall price, performance, and extremely low power consumption. They also tend to produce a relatively low amount of heat, due to solid cooling combined with that low power consumption. The Maxwell architecture has also introduced some new features, but the major changes are to the overall design of the architecture as compared to Kepler. Instead of 192 cores per SMK, there are now 128 cores per SMM. NVIDIA has done a lot of work to improve performance per core as well as lower power in a fairly dramatic way. An interesting side effect is that the CPU hit with Maxwell is a couple of percentage points higher than Kepler. NVIDIA does lean a bit more on the CPU to improve overall GPU power, but most of this performance hit is covered up by some really good realtime compiler work in the driver.
Asus has taken the GTX 750 Ti and applied their STRIX design and branding to it. While there are certainly faster GPUs on the market, there are none that exhibit the power characteristics of the GTX 750 Ti. The combination of this GPU and the STRIX design should result in an extremely efficient, cool, and silent card.

You just don't see CPU overclocking guides much anymore, the process has become much easier over the years as Intel and AMD both now sell unlocked CPUs that they expect you to overclock and the motherboard tools and UEFI interfaces do a lot of the heavy lifting for you now. No longer are you doing calculations for frequency ratios or drawing on your CPU with conductive ink. Overclockers Club is revisiting those heydays with a guide on how to make your $70 3.2GHz Pentium G3258 into a more serious beast with a speed well over 4GHz. The steps for overclocking are not difficult but for those who do not have a background in overclocking CPUs, the verification testing steps they describe will be of great value. If you are already well versed in the ways of MemTest86 and Prime95 then perhaps it will be a nice reminder of the days of the Celeron and the huge increases in frequency that family rewarded the patient overclocker with.
"To reach 4.7GHz was a cinch once I adjusted all the smaller voltage settings. Like all overclockers, it was a journey with many failures along the way. One day it would boot and run Prime95, and the next time Windows would not load. It took a while to sort it out by backing down to 4.5GHz and raising each setting until I settled on the below settings."

Thankfully, they were not "firing" on all four cylinders; while Ryan does prefer thermite, overclockers tend to prefer liquid nitrogen. There are some distinct advantages of ice over fire, the main one for computer users is the potential for massive bumps in frequency and voltage. Of course, you cannot really get any effective use out of a machine that relies on a steady stream of fluid cold enough that it takes less digits to write out its temperature in Kelvin, but a large bump makes good bragging rights.
Finnish overclocker, "The Stilt", managed to push his four-core part to 8000.39 MHz just long enough to have CPU-Z validate his accomplishment. With a frequency multiplier of 63.0 atop a bus speed of 126.99, this gets within 800MHz of the AMD FX-8350 running on just one module (6 of 8 cores disabled) recorded by ASUS late last year.
But no, it will probably not run Crysis.

ASUSTeK has just accomplished a new world record overclock with their ASUS Maximus V Extreme motherboard. They calculated 1 million digits of Pi in a time of 5s 94ms which beats the current best time 5s 125ms according to HWBot. This result once validated lands the Maximus V Extreme in the 1st, 2nd, 3rd, and 4th place positions.
ASUS has once again broke records in the Pi eating contest with their Maximus V Extreme motherboard.
It must be a fun day for an overclocker when you get to play with Liquid Helium. While I attended the Physics department of Queen’s University up here in Canada the facility was known for its condensed matter group. Much of the building was fitted with piping to recapture and recondense the Helium after its experiments strictly due to how much it cost and how rare it is. If someone offers for you to break an overclocking record with it you are obliged to say yes.
The achieved overclock appears to be tuned towards the application. Memory frequency was kept at 1333 MHz with a FSB of about 110 MHz. I would expect this multiplier-centric overclock is designed to keep the overclock focused on sheer number crunching which Super Pi likely relies on over memory bandwidth. Perhaps reduced memory timings might even come in to play for applications like this?
ASUS broke a few records with their Liquid Helium attempt. As of time of writing none of these records have been updated to the HWBot leaderboard.
With Super Pi running to 1 million digits Asus and their team recorded a time of 5s 94ms -- 31 milliseconds faster than the current leading time of 5s 125ms. The current leaderboard already contains the ASUS Maximus V Extreme motherboard in Gold, Silver, and Bronze positions. This podium has already been well represented by the Maximus V.
When you cannot be satisfied with 1 million digits of pi you can run the marathon to 32 million digits.
The most current record that I could find was set by a team sponsored by GSkill who achieved the time of 4min 44sec 609ms just a couple of weeks ago. ASUS and their team - which apparently has at least one member, “Smoke”, in common with the team GSkill assembled - also beat this record by almost 2 full seconds with a score of 4min 43s 0ms.

As promised [H]ard|OCP has spent some time overclocking the ASUS GTX 660 DirectCU II card and have come back with their results. The highest GPU clock they managed was a reported 1170MHz Boost clock in GPU Tweak but which was 1215MHz in actual in-game performance. While that was the high speed record it did not provide the best performance as the frequency often dipped much lower because of the heat produced, [H]'s sweet spot was actually a 1100MHz Boost clock, in-game a much more steady 1152MHz though it did still dip occasionally. They also upped the memory, but again because of the heat produced by the overclock they could not raise voltage without negative consequences. Check the whole review here.
"We put our new ASUS GeForce GTX 660 through the ringer of overclocking and make real world gaming comparisons. If you are thinking the new GTX 660 (GK106) GPU will be a good overclocker like its bigger brother GK104, you may be in for a surprise that puts the new GTX 660 in a new light."
