    Coolers is one of the many variations of the line of branded coolers DirectCU II, which is a feature of direct contact copper heat pipes to the surface of the graphics chip. In this case, we have a large enough radiator, aluminum plates, which are riddled with three massive 8mm heatpipes, pressed into the aluminum base. Direct contact with the GPU to speed up the crystal heat transfer, transferring it to the radiator with a large area of heat dissipation. On one side of the base of the thermal interface material is available, which covers the memory chip that is not covered by the air flow activity from. Construction blown two 80-millimeter axial fans.

    Top design covered protective plastic casing in black, which visually separate the bright red stripes. Nickel plated heatpipes several protrude from the cap, but not critical increase the size adapter, rather giving some appearance of solidity of the cooling system and the video card in general.

    In addition to the original cooler for ASUS GTX660-DC2O-2GD5 also uses proprietary circuit board manufacturer. The compact 175-mm PCB has given way to much more headroom textolite platform length of 250 mm. Increase in size is associated with the fact that the model from ASUS has a reinforced power system. If the reference card has a 4 +1 VRM circuit, in this case, the option semifazny (6 +1). At the same components used Super Alloy Power, as well as controller DIGI + (ASP 1212) to adjust the parameters of the stabilizer.

    Note that the memory chip (Samsung K4G20325FD-FC03) are located on both sides of the printed circuit board, four on each.

    The printed circuit board is made in black, with a matte finish. A similar method is often used to make the showiness of the motherboard, and is now used for the visual refinement of graphics cards. Another remarkable element of the decor - bright etched inscription «ASUS» on the fixing piece of PCB, which is located next to the ground pins PCI Express.

    The top panel contains a connector for additional power supply. Given the rather modest requirements GeForce GTX 660 on the part of energy consumption (TDP - 140 W) in order to enable only one six-pin connector. Excessive requirements for the power supply is also not, the developer recommends using models from 450 W and above, who can provide current up to 24 A at 12 V line

    Note that next to the power connector has a pair of LEDs signaling the supply additional power. Red light recalls that the Council of the cable is not connected, and green - supports connection to 12 V line

    On the top edge of the card is also decorated with the logo attached bracket, at the same time performing the functions of additional ribs.

    The interface panel has the usual equipment. On the dual-slot plug has four video outputs: a pair of DVI (DVI-I and DVI-D), as well as full-length HDMI and DisplayPort. Here is also a grill for ventilation. Plate is increased, and molded so as to direct the air flow out of a PC. Of course, in the case of axial fans can only speak of partial withdrawal of hot air, but this method will slightly increase its volume.

    Scope of supply

    The delivery is not something extraordinary: a guide, a CD with drivers and a DVI to D-Sub connection to the video display device using an analog VGA-interface.

    In

    After installing the adapter, before the operating system boots, it was obvious that the cooler is at least decent job of cooling. Visually low speed at the start - a good sign. GPU-Z confirmed the first hypothesis - in idle 28 degrees and 1,050 rev / min on the tachometer. The fans are quiet, almost inaudible in the noise. Good, very good. But, of course, of great interest to conduct on-load. Here efficiency DirectCU II version used to a full extent. Upon completion of the full cycle of game tests, the peak temperature for the chip was 61 degrees at this time of fan speed were increased to 1500 rev / min. The noise level in this mode increases very slightly.

    Annex Furmark GPU warmed up to 62 degrees, but it should be noted that in the regime created by this utility, TDP adapter exceeds the specified threshold of 100%, and therefore, the mechanism pass measures to reduce the operating frequency and power consumption of the graphics card. As a result, during the inhumane torture "bagel», GPU working at 915-940 MHz.

    In general, the temperature readings are very decent, although, of course, is aware that they are obtained in an open stand.

    Acceleration

    GeForce GTX 660 supports GPU Boost, which in the case of the GTX660-DC2O-2GD5 during a typical gaming load dynamically speeds up the chip from the default 1020 MHz up to 1110 MHz. Such avtorazgon gives some performance boost, which does not require any action from the user. And if you want to get a little extra frames / c, we must take the initiative and take the time to search for the mode in which the card is stable.

    Increasing the voltage of GPU to 50 mV, and the Power Limit increased to 110% (maximum) GPU core frequency was increased to 1098 MHz (7.6%). GPU Boost mechanism in this case continues, automatically speeding up the kernel to ~ 1175 MHz. As for memory, it was stable at frequencies up to 6856 MHz (14.1%). The results, if not a record, it is very convincing.

    How additional boost to performance can be assessed by following the chart view, but with regard to heating the video card in this mode, there is, again, you can let go of some flattering epithets used modified cooler DirectCU II. After dispersal from the pull-chip temperature under load game just increased to 62 degrees, and the fan speed increased to 1620 rev / min.

    Performance

    In order to evaluate the video card in the list of participants rapid test we included the GeForce GTX 650 Ti. Most models on the market from the outset have overclocking GPU, because the tests we used the adapter, GPU is overclocked to 993 MHz instead of 928 MHz recommended by NVIDIA. Also for comparison, the total pool of adapters included "high school» - GeForce GTX 660 Ti, based on a simplified version of the top GPU GK104.

    As you can see, between the GTX 650 Ti and GTX 660 - the abyss. The difference in performance is very significant, as well as in value. Anyway, for those who, for one reason or another trusted graphics cards with only chips from NVIDIA, and wishes to obtain a sufficiently high frame / c in games, will have to look in the direction it is GeForce GTX 660. Unfortunately, the developer no longer adapter that would occupy an intermediate niche between, GTX 650 Ti and GTX 660. Not long ago on plans to provide NVIDIA GeForce GTX 660 SE has not been confirmed by the developer.

    Returning to ASUS GTX660-DC2O-2GD5, we note that this model is in the normal mode is for 1.5-5% of performance, while additional overclocking increases the gap to 9-13%, in some cases, allowing the graphics card to show results at the level of those for the stock GeForce GTX 660 Ti. The latter is also very well to overclocking, however, this is still an adapter higher price class. And it's a good reason for which at the moment is GeForce GTX 660 we recommend for optimal gaming configurations in our traditional category " PC of the month. "

    Radeon HD 7850 figures are not so convincing, but the frequencies of the reference values of the adapter is very low, and the potential to break up high. Thus excellent performance scaling allows for a very significant performance increase (25-30%), allowing the adapter to feel more confident in the game the celebration of life in the mid-market. Radeon HD 7870 is quite competitive even in normal mode, but the balance of power in any particular case depends essentially on the optimization of game engines.

    Results of

    ASUS GTX660-DC2O-2GD5 - a good example of the spacecraft can be improved initially a good graphics card. Taking a good GPU, improving component base and generate an efficient and quiet cooling system, the output is a hit average. Card would be of interest to those who consciously chooses the device, focusing not only on the brand, the name of the line cards and memory.

    ASUS offers three versions of GeForce GTX 660, made on the same platform. In our opinion, it is a modification «OC», being a kind of golden middle. In normal mode, it has a higher clock speed of the chip, they find themselves quickly reference models, with the device cost only slightly above basic model (GTX660-DC2-2GD5).considered above TOP version - originally

    The most productive of GeForce GTX 660, and if someone it does not want to mess around with the sliders independently tuning utilities, and $ 10-15 for an extra performance boost - the amount is quite acceptable, then this option will be very attractive.
