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.

The MSI N760 might come with a factory overclock but that doesn't mean it is at its maximum potential straight out of the box. With the help of MSI's own Afterburner tool [H]ard|OCP undertook the project of maximizing the overclock on this GTX 760 by upping the power available to the card to 145%. They maxed out at a base clock of 1160MHz and boost clock of 1225MHz and were even more please to see the card actually running at 1280MHz under load. With that increased core speed and memory upped to 6.4GHz the effect on performance was notable and pushed this card beyond the performance of the competitors.
"We take the new MSI N760 TF 2GD5/OC video card and overclock it to its highest potential with MSI Afterburner. We don't stop there, we also overclock all the comparison cards to their highest potential, and see if the GTX 760 can still hold its own. We also compare performance with the Radeon HD 7950."

During Computex 2013 in Taipei, Taiwan, Intel and Corsair sponsored the Computex OC Main Event where overclockers set out to push some of the latest hardware to the max. The ASUS Maximus VI Extreme motherboard was one of the pieces of hardware used at this event, and it was the board used in 10 out of 11 winning overclocking runs. Further, it was used in runs that ended up breaking a total of 8 world overclocking records.
Overclockers were able to achieve top spots for a number of benchmarking scores as well as CPU and GPU clockspeeds. The benchmarking records include new high scores for 3DMark01, 3DMark05, 3DMark06, SuperPi 32M, PiFast, and AquaMark3. The overclockers were also able to push an Intel "Haswell" Core-i7 4770K processor to an impressive 7092.68 MHz with HyperThreading disabled and two physical cores active. Considering how stubborn the new Haswell chips are when it comes to overclocking, hitting a bit over 7GHz is quite the feat. CPUs were not the only pieces of hardware that were pushed to the limits, however. Overclockers were also able to overclock four DDR3 DIMMs to 3957 MHz with 13-16-16-45 timings.

The breakdown of the new top benchmarking scores for the various software used at the OC Main Event (from systems using the ASUS Maximus VI Extreme board, Haswell CPU, and GTX TITAN) is listed below.
|SuperPi 32M||4m, 35s, 406ms|
|Haswell Clockspeed||7092.68 MHz (two cores)|
|DDR3 Clockspeed||3957 MHz (13-16-16-45)|
Naturally, ASUS is extremely pleased with the performance of its new motherboard, which proved stable enough to support some impressive CPU, GPU, and RAM overclocking under LN2 and extreme clockspeeds. I'm looking forward to see what Morry is able to achieve using the board in a more real world 24/7 overclock scenario in our upcoming OC review using this ASUS board!

Intel Prevents Overclocking of non-K Haswell Processors, and Strips Virtualization and TSX Features From K Parts

First revealed at IDF Beijing, Intel's latest generation 4th Generation Core "Haswell" processors enjoy a refined architecture, improved processor graphics, an integrated voltage regulator (FIVR), and for the enthusiast crowd, new methods for overclocking.
In truth, the methods for overclocking Haswell are very similar to those used to overclock Intel's Sandy Bridge and Ivy Bridge processors. However, Intel has further unlocked the new Haswell CPUs. Enthusiasts can set an overclocked Turbo clockspeed, use additional base clock (BCLK) values (100 MHz, 125 MHz, and 167 MHz), and overclock the unlocked processor graphics core clockspeed and memory clockspeed (memory in 200 MHz or 266 MHz steps). The additional BCLK values allow for easy overclocks without putting the other subsystems (such as the PCI-E bus, GPU, and memory) out of spec, which is important for the PCI-E bus which needs to be close to 100 MHz for a stable system.
The following PC Perspective articles have further information on overclocking unlocked "K" edition Haswell processors:
- Integrated Voltage Regulator and Overclocking Haswell - Ryan pushes a Core i7-4770K to 4.6GHz
- Intel Talks Haswell Overclocking at IDF Beijing - Intel outlines overclocking features of Haswell at IDF
Although Intel's overclocking reveal at IDF was fairly detailed, the company did not get into specifics on how overclocking would work on non-K chips.
On that note, the crew over at the Tech Report uncovered some rather disheartening facts such that the non-K edition Haswell processors will, essentially, be locked at stock speeds and not overclockable (they are slightly more locked down than previous generations).
While the K edition Haswell processors, such as the Core i7-4770K, will enjoy unlocked multipliers, unlocked GPU and memory clockspeeds, and additional BCLK options, the standard non-K chips (ie Core i7-4770, Core i5-4670, et al) will have locked multipliers, no Turbo Boost clockspeed overclocking, and will not be allowed to use the additional 125 MHz and 167 MHz BLCK options, which effectively makes overclocking these standard chips impossible. It may still be possible to push the BLCK up a few MHz, but without the extra
stepping and gearing ratio options, the other component clockspeeds based off that same base clock are going to go out of spec and will become unstable fairly quickly as you try to push that BLCK up.
There is one saving grace for enthusiasts considering a non-K part, however. The standard non-K CPUs will have Intel's latest TSX extensions and enterprise virtualization technologies enabled.
Although quite the head scratcher, Intel has decided to disable TSX, vPro, and VT-d on the unlocked K edition chips. The TSX extensions are not widely used yet, but will provide a noticeable performance boost to future programs that do take advantage of them by allowing developers to essentially mark off sections of code that can be run independently, and thus increase the multi-threaded-ness of the application by running as much code in parallel across multiple cores as possible. Further, the vPro and VT-d features are used by virtual machine applications (with VT-d being more relevant to the consumer side of things).
In short, Intel has continued to lock down and artificially limit its chips, as many enthusiasts suspected would happen. Standard non-K Haswell processors are more locked down than ever, and even the premium unlocked K CPUs suffer with the (odd) removal of TSX and virtualization support. As Mr. Gasior points out, enthusiasts are going to be faced with an odd choice where they can either spend extra money on a premium K part that will overclock but is limited in other ways, or go with the lower cost part that has all of the ISA extensions and virtualization support turned on... but is not overclockable.
In my opinion, locking down the standard chips is one thing-- Intel needs to incentivize enthusiasts to go with the more expensive (~$25 premium) unlocked K processors some how -- but if those same enthusiasts are spending extra money for a premium chip, they should get all the features the accompanying non-K SKU has as well as overclocking.
What do you think about the artificial limitations placed on the various Haswell SKUs?

[H]ard|OCP liked the new GTX 770 Lightning from MSI but thought they would like it better overclocked, perhaps even more than a GTX 680 or HD7970. The triplets below are, from top to bottom, the GTX 680, the GTX 770 and the HD7970, all from the overclocked Lightning family. By using MSI's Afterburner utility [H] pushed the card to 1241MHz on the core and 7.8GHz effective for the RAM, higher than the factory overclock. That speed boost put its performance on par with the overclocked GTX680 but it seems that the impressive speeds that the 7970 Lightning is capable of leaves it comfortably in the lead.
"We take the new MSI N770 Lightning and overclock it to its maximum potential. We will compare it with a highly overclocked MSI GeForce GTX 680 Lightning and GIGABYTE Radeon HD 7970. Each GPU is getting its best chance to show us how well it can perform, as all of these GPUs are highly overclocked."

If you haven't read your fill about Haswell's architecture you should cast your eyes onto Ryan's full review for an indepth look at the new design of Intel's Core processors. If you have already done your homework and are now more interested in how well this new processor can overclock then heading to [H]ard|OCP will satisfy your curiosity. When testing for the best overclock [H] utilized two different Z87 boards from ASUS to ensure we could see what the processor could do, not just what the motherboard was capable of but in the end the results were similar. They also included a quick guide at the end for those wanting to apply an overclock without spending a lot of time in the BIOS. Check it out here.
"Intel's clock keeps ticking and today lands on a "tock" in the development cycle. The new desktop Haswell processor represents a new microarchitecture built on the tried and true 22nm process technology that we have come to know and love with Intel's current Ivy Bridge microarchitecture. But what does Haswell mean for the computer enthusiast?"

G.Skill is a company known for its DDR3 memory products and overclocking contests. It recently unveiled a new 32GB DDR3 RAM kit under its TridentX series that is clocked at an impressive 3,000 MHz!
The new G.Skill DDR3 3000MHz 32GB (4 x 8GB) memory kit is aimed at enthusiasts running Intel Haswell processors on Z87 motherboards. It features CAS12 latencies and can be run at 1.65V. It also supports Intel's XMP (Extreme Memory Profiles) standard, which will allow the motherboard to automatically configure the RAM for the full 3000 MHz clockspeed, though it requires a slight CPU overclock as well.
In G.Skill's own benchmark tests, the company managed to run its new 32GB TridentX memory at 3,000 MHz with CAS latencies of 12-14-14-35-CR2 at 1.65V. The Memtest Pro benchmark run was done on a system with an Intel Core i7-4770K and an ASUS Maximus VI Extreme Z87 motherboard. The Intel chip was running with a bus speed of 102.32 MHz and a multiplier of 39 for a total 3.99 GHz core clockspeed with all cores under load. Considering the i7-4770K is only rated for a maximum of DDR3-1600 memory, seeing it running DDR3 at 3GHz is impressive!
The new 32GB (4x8GB) TridentX kit is joined by 8GB (2x4GB) and 16GB (4x8GB) kits that are all rated for DDR3-3000 speeds. The kits continue to be covered by G.Skill's lifetime warranty. The company has not announced pricing or availability, but expect to pay a hefty premium for this super-fast RAM. Think upwards of $1,750 considering the existing 32GB DDR3-2933 C12 G.Skill kit is going for $1,700 on Newegg.
