GeForce GTX 680 was overclocked to 1442 MHz, using air-cooled

Overclocking enthusiast k | ngp | n explore the potential of increasing the clock frequency on GeForce GTX 680 sample 3D-card EVGA GTX 680 SC. With the use of "extreme cooling" graphics processor was overclocked to 1957 MHz.

More interesting is the result of dispersal from the air cooling system, accessible to more overclockers.

In this case, k | ngp | n and the EVGA GTX 680 SC was subjected to 1442 MHz mark. Recall from the reference sample base clock frequency is 1058 MHz, high - 1124 MHz.

 

As can be seen in the illustration, with the GPU voltage had to increase to 1.212, which corresponds to the upper limit stipulated by NVIDIA. Memory clock was 1812 MHz.

The system used to disperse, was part of the processor Intel Core i7-3960X, overclocked to about 5 GHz, and the memory running at 1245 MHz (effective 2490 MHz). In 3DMark 11 the result was recorded P12745.

The catalog appeared EVGA 3D-card GeForce GTX 680 SC Signature and Signature + with Prices

EVGA Company added to its online catalog of two 3D-card to a 28-nanometer GPU NVIDIA: GeForce GTX 680 SC Signature and GeForce GTX 680 SC Signature +.

Both cards are overclocked at the factory. Core GPU clock speed is 1084 MHz (GPU reference model is clocked at 1006 MHz), high - 1150 MHz (1058 MHz). Increased clock speed and 2 GB GDDR5 - from 6008 to 6208 MHz.

Power supply circuit consists of five phases of the PWM. The additional power is supplied by six-and octal sockets. Recall from the reference sample - two six-slot.

Cards support PCI Express 3.0, SLI and 3D Vision Surround.

On the mounting bracket can be found two DVI and one HDMI connector and DisplayPort.

Price GeForce GTX 680 SC Signature - $ 530. Model GeForce GTX 680 SC Signature +, wherein the presence of a metal plate on the back of the printed circuit board, costs $ 550.

Accelerator Gainward GeForce GTX 680 Phantom: the original cooler and PCB, the increased frequency

Company Gainward officially announced the accelerator GeForce GTX 680 Phantom . His unusual name must map the location of the two fans at the radiator and the heat pipes.

This is the second generation of corporate cooler Phantom, in which the manufacturer has paid attention to the structure of the heat sink, improving cooling efficiency, structural strength and reducing the generated noise. The tradeoff for efficient cooling of steel overall size of card: despite the use of two mounting holes, the accelerator is 2.5 slots, in the terminology of Gainward.

However, the buyer will receive the card overclocked by the manufacturer: GPU frequency up to 1150 MHz (basic frequency of 1084 MHz), the memory runs at 6300 MHz effective frequency, its size is 2 GB. From our review, you can see how important the performance of the memory card GeForce GTX 680. According to Gainward, this allows you to overclock the new product gain of 12.6% points more in 3DMark 2011, in the real games will be an increase of 10%.

Six-phase power system with regulators DrMOS contributes to the overclocking potential of the maps, to further "tuning" you can use the proprietary utility Expertool II. The image is displayed using two ports DVI, a DisplayPort and HDMI. The price Gainward card does not say, as the timing of the appearance on the market.
