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."

The majority of the GTX 660 Ti models run faster than the stock clocks, with some having a Boost Clock approaching 1.1GHz and some sporting memory overclocks as well. This lead [H]ard|OCP to ask two questions; just how fast can the card go and are you better off with faster memory or a faster processor. When they left the GPU as is, they could hit an effective speed of 7.71GHz and when they returned the memory to the base speed they pushed the core to 1.3GHz. Along the way they discovered that the reported clocks might be a bit lower than the actual clocks, which is a nice bonus to owners. Read on to see what happened when they overclocked both components.
"We've evaluated the GALAXY GeForce GTX 660 Ti 3GB video card, now it is time to overclock it to its maximum potential with XtremeTuner Plus and find out how it compares to the GTX 670 and Radeon HD 7950. We will also find out if it is best to concentrate on the GPU clock speed or its 192-bit memory speed to get the best performance gains."

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!

Popular motherboard manufacturer Gigabyte is the latest company to debut a custom version of the NVIDIA GTX 680 reference graphics card. Gigabyte’s unique take on the GTX 680 starts off with a custom dark blue PCB and ripping out the puny two six pin PCI-E power connectors. They are then replaced with one eight pin and one six pin PCI-E power connector. Then, they top it off with a custom three fan cooler. The heatsink uses three copper heatpipes with direct contact with the GPU, and two arrays of aluminum fins.
The cooler and blue PCB via VR-Zone
The extra power provided by the eight pin PCI-E connector allows for potentially higher overclocks (depending on the particular chips), and the custom cooler keeps the overclocked card nice and cool. In fact, Gigabyte is shipping the card with a factory overclock. Although they did not overclock the 2 GB of GDDR5 memory from stock, they have set the base clock frequency and boost frequency at 1071 MHz and 1124 MHz boost respectively. Compared to the reference specs of 1006 MHz base and 1058 MHz boost, that amounts to a respectable 65 MHz base overclock and 66 MHz boost overclock out of the box. Further, depending on the chip, they may be capable of overclocking much higher.

So long as you can find one in stock, the NVIDIA GTX 680 GPU is shaping up to be an interesting card, especially the custom versions! More photos of the previewed Gigabyte GTX 680 WindForce edition is available here and here.

One quickly forgets about the initially released reference GPUs once the cards with custom coolers, capacitors and PCBs arrive on the market all cool and factory overclocked. Usually the original GPU and card designer, in this case AMD, licenses theit top tier partners, like MSI , Gigabyte or Sapphire, to sell cards following a design that AMD provides along with the license to design and sell the cards. As SemiAccurate points out, this has lead to a market where the only unique feature they can add is usually armed and wearing a bikini. After the card has been on the market for a while, then AMD allows non-reference designs to appear for some cards from some manufacturers.
Not so with one of the four lineups of GPUs soon to arrive on the market, AMD will be freeing us from the tyranny of Ruby in different outfits and allow their partners to modify the Tahiti Pro cards from the get go. Expect to see a large difference in the appearance and specifications of AMD's new high end series of cards. That is the only one of the four to get this treatment, Tahiti, Pitcairn and Pitcairn XT cards will still come out only as copies of the reference card design. This may change over time but for now the idea of custom cooler, power distribution and PCB design is something to look forward to in the coming years.
"Back to the new news, and it concerns the Tahiti Pro card. Word has reached SemiAccurate that Tahiti Pro will be unconstrained to the normal reference designs. If you recall, most GPU manufacturers will force AIBs to make cards based on the reference design for the first 3 months or so, and there are a variety of very good business reasons to do this.
Unfortunately, it leads to a problem where the reviews all are the same, mainly because all the cards are the same. The main difference between manufacturers comes down to what color the AIB decides to put on the chrome bikini of the girl with the big sword riding the mythical beast just below their logo. We are partial to Hafnium bikini’s on women riding giant Were-moles around here. Luckily, Tahiti Pro changes this."

Remember back in September when Ryan was all excited about seeing AMD exceed Intel with their Liquid Helium-cooled overclock? 8.429 GHz bulldozed past the 8.309 GHz record set upon Intel’s Celeron and all rejoiced at AMD’s 130 MHz triumph. Well out with the old and in with the new: there is a new overclocking king and it goes by the name of -- well it is also the AMD FX-8150. That is irrelevant, however, as the new record (if validated before someone beats it too) has become 8.461 GHz.
Someone’s the new king in town… the current king.
The new world record was set by Andre Yang, an overclocked from Taiwan, with an ASUS Crosshair V Formula motherboard. Benchmarks were not possible as when you get overclocking to this level: successfully running CPU-Z just to query the specifications of a CPU is generally considered sufficiently stable to be qualified as an overclock. Do not be surprised if SuperPi blows a hole through your chassis. It was not stated which method of cooling was used to allow the processor to reach those specifications.
