Lightning twice / video card



All modifications to the GeForce RTX 2080 Ti that we have covered so far have been significantly accelerated and satisfy the majority of buyers' ambitions. But for enthusiasts who are struggling with record performance, NVIDIA partners initially offer products that operate at higher frequencies. The leading chips in the Turing family are divided into two categories: achievable clock speeds and the purchase of a "premium" video card, ensuring that overclockers do not lose much of their silicon roulette.

When NVIDIA released the Kepler, Maxwell and Pascal architecture chips, MSI led several times over the factory overclocking of certain models. And this time, NVIDIA's flagship accelerator with the highest clock speed appeared under the wings of the red dragon MSI.

⇡ #Specifications, shipping range, price

A ray traceable flag accelerator with hardware modules (RTX 2060, 2070, 2080, and 2080 Ti) from four NVIDIA models in the Turing architecture boasts the lowest clock speeds. The Boost Clock with a default frequency of 1350 MHz (ie the average frequency of a typical game load) is only 1545 MHz when judged to be reference data or 1635 MHz modified by Founders Edition. At the same time, thanks to its extensive computing pipeline, the TU102 chip enjoys the benefits of overclocking the most. As soon as the RTX 2080 Ti remains the premier gaming graphics card in the latest AMD and NVIDIA products, the GeForce TITAN RTX is almost useless to gamers. The only way to get a new performance peak is to start overclocking.

MSI offers two versions of GeForce RTX 2080 Ti LIGHTNING. The "generic" version features a boost clock frequency of 1575MHz, so the GeForce RTX 2080 Ti LIGHTNING Z improves up to 1770MHz, but does not extend to Foundstone Edition. It is also an important achievement for the TU102 chip, not NVIDIA. Because the Founders Edition video card reaches 1.044V for comparison, the space for the software vault in the TU102 is very limited.

Otherwise, the frequency parameters of both devices will not deviate from the reference specification in that the GPU's default frequency is 1350 MHz and GDDR6 main memory operates at a bandwidth of 14 Gbps per bus contact.

But the durability of GeForce RTX 2080 Ti LIGHTNING Z does not consume a record high GPU clock speed. The power reserve of this device is 360W (compared to 373W for EVGA video cards but 450W for GALAX / KFA2 models), the power consumption of Founders Edition is limited to 260W. Additional overclocking firmware for GeForce RTX 2080 Ti LIGHTNING Z is also available. The question of the power required to successfully overclock the TU102 without using extreme methods will be discussed in detail in the last section of this article, but the special BIOS of the video card will not flash by default. MSI issues it on an individual request.

At the Russian online shop GeForce RTX 2080 Ti LIGHTNING Z sells a predictable large amount of 102,000 rubles, but the cheapest modification of the GeForce RTX 2080 Ti is already on the price list of 73,000 rubles. a little. This will be studied in minutes, with record factory overclocking costs and robust design. However, the general version of this model without the Z index was not sold in the domestic or US markets. In general, Amazon.com offers a single copy of GeForce RTX 2080 Ti LIGHTNING Z for US $ 5,999.

By the way, the GeForce RTX 2080 Ti LIGHTNING Z is a rare example of a video card with a rich bundle of our time. There are several useful accessories attached, including a heap of text provided with the software disc, as well as a metal spreader (with a multimeter probe attached to a test point on the PCB) to further secure the board to the PC case and cable.

⇡ #erection

Although the thickness of the 2.5 expansion slot became the standard for video cards based on the TU102 chip, MSI boldly increased the total size to three full slots. The unit is 328 mm long and weighs almost 2 kg (1825 g, precisely). MSI was very impressive, but MSI turned out to be a very hard and stable structure. Soon it will show how this work was done. But first we give the device aesthetics. GeForce RTX 2080 Ti LIGHTNING Z does not require the best design for your computer components. For example, people using multicolour lighting would not be surprised. However, each luminous strip of the hull and the rear panel of the hull consist of numerous light sources (or other pattern-dragon control center software) in which the rainbow wave moves. The cooling fan is also illuminated by the RGB LEDs and the stroboscopic effect creates a variety of shapes on the blades.

And most importantly, the versatile OLED display is mounted on the side panels of the case, making it very bright even in sunlight. The screen displays temperature, GPU clock speed, or other video card operating parameters. Any gif file can be output.

Three impellers are responsible for radiator airflow. Two impellers use double ball bearings with diameters of 95 mm and 85 mm. Each fan has 14 blades in different shapes. The standard soft petals push the air out and the protruding blades accelerate the air flow further according to the manufacturer.

The heat of the graphics processor destroys huge radiators and takes up almost all the free space under the casing and cooling system fans. The ribblocks are divided into two interconnected parts and have a glossy copper base with heat pipes. There are nine pipes of various diameters.

Except for GPU boards, protruding capacitors, and voltage regulator chokes, the area of ​​the printed circuit board is covered by a thick aluminum frame with small corners. Because the PCB is firmly fixed to this part, the PCB does not bend at all with the massive radiator weight. The thin plate that protects the backside of the printed circuit board is not similar to the appearance of "carbon". This is real carbon fiber. The MSI does not have a high thermal conductivity, but for some reason has plugged the heat pipe. However, there is no high heat dissipation factor on the back of the PCB.

⇡ #Circuit board

Large cooling systems such as MSI GeForce RTX 2080 Ti LIGHTNING Z can save printed circuit board area. In fact, the PCB has enough free space, but the width of the PCB is sufficient to line up the 13 step components of the voltage regulator and six steps are soldered on the opposite side of the GPU. 16 of these are part of the VRM of the graphics processor and three of them support GDDR6 chips. Like other boards for the Turing chip, MSI features a field effect transistor with an integrated driver (Dr. MOS or power stage-power stage) featuring high energy efficiency and high-precision voltage control. Each MOSFET is rated for a maximum of 70A of current. According to the specification, VRM can provide 1330W capacity devices. Cryogenic cooling keeps safety margin even when overclocked.

All two stages of the GPU power system are connected to the controller via a PWM signal doubler. This reduces the current through the separate phases and greatly improves the overall efficiency of the regulator. Like all video cards in the Turing GPU, the MSI GeForce RTX 2080 Ti LIGHTNING Z can pull off some of the phase with less graphics processor load. To serve as a PWM controller for GPU and RAM chips, manufacturers have chosen the very rare Monolithic Power Systems chips from the MP2888A and MP2884A models.

The unit is powered by three 8-pin connectors. Although it does not need to operate in normal mode and moderate overclocking in the third slot, this video card was initially tuned for extreme overclocking. The board has a pad that monitors the power supply voltage of the GPU, GDDR6, and PLL chips, and a miniature switch that activates the backup BIOS chip. The new video card includes passive cooling below 60 ° C in the redundant firmware and can increase power conservation up to 400W, but at the request of the buyer, MSI will issue a BIOS that exceeds the limits required for liquid nitrogen testing I agree.

The MSI GeForce RTX 2080 Ti LIGHTNING Z video output kit is the standard for Turing high-end accelerators that can be used to connect other peripheral devices, including USB Type-C connectors that support three DisplayPort outputs, one HDMI and DisplayLink protocol.

Micron's RAM chip (represented by the K4Z80325BC-HC14 line) operates at a standard bandwidth of 14 Gbps.
