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."

Fremont, CA (August 16, 2012) - The ASUS DirectCU II range of graphics cards continues to expand with the ASUS GeForce GTX 660 Ti DirectCU II series featuring the Standard, OC and TOP editions. Utilizing the latest 28nm graphics technology from NVIDIA, the OC and TOP cards deliver a factory-overclock while all three cards feature exclusive DirectCU thermal design and GPU Tweak tuning software to deliver a quieter, faster, and more immersive gameplay experience that redefines the term affordable performance.
Superior Design and Software for the Best Gaming Experience ASUS equips the GeForceGTX 660 Ti DirectCU II series with 2GB of GDDR5 memory clocked at 6008MHz. The TOP edition features a blistering GPU core boost clock of 1137MHz, 157MHz faster than reference designs while the OC edition arrives with a factory-set GPU core boost speed of 1058MHz. Exclusive ASUS DIGI+ VRM digital power delivery and user-friendly GPU Tweak tuning software allows all cards to easily overclock beyond factory-set speeds offering enhanced performance in your favorite game or compute intensive application.
The ASUS GeForce GTX 660 Ti DirectCU II series feature exclusive DirectCU technology. The custom designed cooler uses direct contact copper heatpipes for faster heat transduction and up to 20% lower operating temperatures than reference designs. The optimized fans are able operate at lower speeds providing a much quieter gaming or computing environment. For enhanced stability, energy efficiency, and overclocking margins the cards feature a six-phase Super Alloy Power design for the capacitors, chokes, and MOSFETs meant to extend product lifespan and durability while operating noise-free even under heavy workloads.
ASUS once again includes the GPU Tweak tuning suite in the box. Overclocking-inclined enthusiasts or gamers can boost clock speeds, set power targets, and configure fan operating parameters and policies; all this and more is accessible in the user-friendly interface. GPU Tweak offers built-in safe guards to ensure all modifications are safe, maintaining optimal stability and card reliability.

ASUS' family of DirectCU II TOP have made a good name for themselves with enthusiasts, coming from the factory with impressive overclocks and a quiet and efficient custom cooler. There is a new member of this family, the GTX670 which comes with a default clock of 1059MHz and a boost clock of 1137MHz though the memory remains unchanged at 6GHz. These cards have more than just a custom cooler, the capacitors and switches are significantly better than the ones found on other cards which gives the card a longer lifespan as well as giving it serious overclocking headroom which you can see in action in [H]ard|OCP's review. At $430 it does cost a bit more than the stock version, but not prohibitively so.
"ASUS has delivered the fastest GeForce GTX 670 on the market in the ASUS GeForce GTX 670 DirectCU II TOP video card. The monster overclock and the improved cooling system are sure to provide the performance we yearn for. We will be testing it in the recently released Max Payne 3 against a GeForce GTX 680 and Radeon HD 7950."

AMD Gets the Direct CU Treatment
In the previous roundup I covered the DirectCU II models from Asus featuring NVIDIA based chips. These boards included the GTX 580, 570, and 560 products. All of these were DirectCU II based with all the updated features that are included as compared to the original DirectCU products. With the AMD parts Asus has split the top four products into two categories; DirectCU II and the original DirectCU. When we start looking at thermal properties and price points, we will see why Asus took this route.
AMD has had a strong couple of years with their graphics chips. While they were not able to take the single GPU performance crown in this previous generation, their products were very capable and competitive across the board and at every price point. In fact, there are some features that these cards have at particular price points that make them very desirable in quite a few applications. In particular are the 2 GB of memory on the HD 6900 series cards where the competition from NVIDIA at those price points features 1 GB and 1.25 GB. In titles such as Skyrim, with the HD texture DLC enabled, these cards start to limit performance at 1920x1080 and above due to the memory requirements needed for these higher resolution textures.
3 NV for DCII
The world of video cards is a much changed place over the past few years. Where once we saw only “sticker versions” of cards mass produced by a handful of manufacturers, we are now seeing some really nice differentiation from the major manufacturers. While the first iterations of these new cards are typically mass produced by NVIDIA or AMD and then distributed to their partners for initial sales, these manufacturers are now more consistently getting their own unique versions out to retail in record time. MSI was one of the first to put out their own unique designs, but now we are seeing Asus becoming much more aggressive with products of their own.
The DirectCU II line is Asus’ response to the growing number of original designs from other manufacturers. The easiest way to categorize these designs is that they straddle nicely the very high end and extreme products like the MSI Lightning series and those of the reference design boards with standard cooling. These are unique designs that integrate features and cooling solutions that are well above that of reference cards.
DirectCU II applies primarily to the cooling solutions on these boards. The copper heatipipes in the DirectCU II cooler are in direct contact with the GPU. These heatpipes then are distributed through two separate aluminum fin arrays, each with their own fan. So each card has either a dual slot or triple slot cooling solution with two 80 mm fans that dynamically adjust to the temperature of the chip. The second part of this is branded “Super Alloy Power” in which Asus has upgraded most of the electrical components on the board to match higher specifications. Hi-C caps, proadlizers, polymer caps, and higher quality chokes round out the upgraded components which should translate into more stable overclocked performance and a longer lifespan.
