Review MSI GeForce GTX 980 Ti Gaming 6G

We have already met with a copy of Gigabyte GeForce GTX 980 Ti G1 Gaming SOC, and then he left some mixed impression. Thus, the power circuit issues the manufacturer was not, but with the noise level should understand at the design stage of the cooling system.

MSI is famous for a careful approach to the design of the SB. Due to this in its graphics cards often choose people who desired a low noise level and high base acceleration. Then we will find out whether the data conform to the requirements of the model, which has become the hero of the review – MSI GeForce GTX 980 Ti Gaming 6G with cooler Twin Frozr V.

The appearance and size

The length of the MSI GeForce GTX 980 Ti Gaming 6G pretty standard, if more than the reference version, quite a little bit. You can not say about the width. Almost 130 mm of which 120 mm pure PCB. In principle, this should not pose major problems in normal cases, but what about those who want to place it in the Mini-ITX? With this card really tall may not fit in a small package.

Set video output is typical: one DVI-D, HDMI 2.0 and three DisplayPort. Even the rear panel is completely borrowed from the basic design.

Printed circuit board

Here it is, the most important and the most important part of any video – design and choice of components.

So, for what it took MSI engineers to expand PCB? The answer lies in the photos, the eight phases of the power of the GPU and two phases of the power of memory.

It seems to be a standard number, the same set of costs on the reference video card! But all of the components are different: MSI has chosen other suppliers, so to speak, even a different type of power transistors.

Typically, two types of graphics cards: the first – Dr.MOS circuit (steam mosfetov (lower plus upper) and drivers in one case), the second – the classic, composed or performed in an expensive three power transistors, or in a simplified, two. They still need to add on the throttle, the driver and others.

But MSI has gone its own way. First, engineers have found and installed the two-channel mosfet SM7320, it added to the driver NCP81061, and four phase-controlled PWM controller, made by connecting eight doublers ON Semiconductor NCP81162. The result was a sort of “Frankenstein.”

How he will behave under load, and whether audible squeaking coil, we learn later.

So far, the scheme looks strange and painfully familiar. It took me three minutes to remember. It turns out the twin brother of our video card – MSI GeForce GTX 980 Gaming 4G. She’s up to the smallest detail, such as the scheme of power circuits. And even PWM controller is identical – NCP 81174.

Power graphics cards made by two 8pin connectors. Total capacity – up to 300 watts of nominal characteristics. The margin of safety circuits and is sufficient for 450-500 watts. The only problem is that manufacturers rarely leave users to use the entire stock.Although, in my opinion – it’s stupid, it would suffice to limit the maximum current.

Food storage is done on a two-phase circuit with conventional circuitry. But none so far have not guessed producer PWM controller.

Twelve memory chips SK Hynix R2C with a nominal frequency of 1750 MHz are located on the front side. In the version of the MSI memory can overclock. The output of 1775 MHz happened.

Graphic processor GM200 assembled onto the substrate 2015, more precisely at 18 weeks. But the factory video frequency dependent on the activation profiles. MSI offers a choice of three modes:

  • OC Mode – 1178 MHz (Boost up to 1279 MHz) / 7096 MHz;
  • Gaming Mode – 1140 MHz (Boost up to 1228 MHz) / 7010 MHz;
  • Silent Mode – 1000 MHz (Boost up to 1076 MHz) / 7010 MHz.

Cooling system

MSI engineers despite the massive enthusiasm from other manufacturers the installation of CO with three fans is limited to two. But they work as part of the cooler Twin Frozr V.

In addition, they are large enough – 95 mm in diameter. But the interesting thing is hidden under the main radiator.

Instead of a single plate teploraspredelyayuschey developers decided to put two independents. One removes heat from the memory and is equipped with an end bend which prevents the PCB from mechanical damage.

Another through thermo removes heat from the power circuits. Its thickness is not more than 5 mm, and to improve the efficiency of the ribs are provided.

The main radiator is low. Without taking into account the closure, then the average of its height does not exceed 11 mm.

Funny, but it is made of two halves joined into one. In place of articulation used mechanical locks.

Thus before us is not a single radiator and two. At one side of the ribs extend across three tails heat pipes, in another – three.

All in all, the cooling system uses four heat pipes: one pair of 8 mm in diameter, the other – 6 mm. The base plate is used to it and they are soldered.

Two turntables with a maximum turnover of about 2300 rev / min distinguished variable pitch blades. Identical design long used in automobile fans to reduce vibration and noise.

Closing

What is the result? Among the positive features of the model MSI GeForce GTX 980 Ti Gaming 6G we note a good cooling system Twin Frozr V. Let it not be called a compact, but it copes well with its mandated task. And thanks to the switchable in just a fan in 2D graphics card becomes silent. It is worth mentioning and very smooth start impellers, and their cyclical shutdown. However, this does not affect the outgoing noise, it is almost there.

As for overclocking, the average full-time overclocking news, the stock frequency is, but small. Pleased with the memory chips SK Hynix, which allowed up to 2050 MHz.

The disadvantages we put the original firmware BIOS. It is fully consistent with the recommendations Nvidia, as a result, the moderate consumption of the graphics card. And only because of this can not be a hundred percent use of the full potential of the power supply system and a cooler. In this scenario, we expect a high acceleration is not necessary.

Perhaps with another instance of the quality of the crystal can be luckier, and in this case, the GPU frequency of 1.4 GHz becomes more real. We were not lucky and all that was possible to squeeze out of the test sample – is the average frequency of 1390 MHz.
