If we rotate the card and look at the backside we can see two SLI connectors, so in theory four cards in quad-SLI GPU mode are supported. Quad SLI however is difficult and often a maze of driver problems, Nvidia has never really recommended and actively supported quad-SLI. But for a handful of benchmarks and sheer e-peen, it will work OK'ish. We really recommend to go with a maximum of 2 maybe three cards. The GTX 780 DC 2 is built with 8+2 phase power delivery, ensuring ample room for experimental performance tuning. The reference cards have a 6+2 Phase design.
The DIGI+ VRM digital voltage regulation design augments precision overclocking capabilities, which are further supported by the use of hardened Super Alloy Power components. The Super Alloy Power technology on ASUS graphics cards use a special alloy formula which is highly-magnetic, heat-resistant and anti-corrosive. It delivers a more stable and quieter operation compared to the reference design. DIGI+ VRM, unlike traditional analog design, is embedded with digital settings to adjust voltage according to different overclocking scenarios. The photo above reveals access point for VGA hotwiring.
For the GeForce GTX 780 launch we'll have multiple articles ranging from single GPU to 2-way SLI. We'll also look at performance based on high-end yet more moderate processors and then on the X79 platform with an overclocked Core i7 3960X running at 4600 MHz. Here we see the ASUS card (you can find it under SKU code GTX780-DC2OC-3GD5) installed on our test bench.
That's it for this photoshoot though. We need to tell you a tale or two about the GPU and the architecture of course.
ASUS GeForce GTX 780 Ti DirectCU II OC review We review the ASUS GeForce GTX 780 Ti DirectCU II OC edition. Customized GeForce GTX 780 Ti graphics cards are a hot thing these days, as they are silent, running cool and offer tremendous rendering ...
ASUS GeForce GTX 760 DirectCU Mini review In this article we review ASUS GeForce GTX 760 DirectCU MINI edition, this particular model comes with a dual-slot DirectCU Mini cooling solution that will fit small form factor based motherboards like Mini ITX up-to 17cm. ASUS has re-engineered the DirectCU cooler to fit small form factor cases. While shorter, it introduces a copper vapor chamber placed directly on top of the GPU for faster heat spreading and dispersal with lower temperatures than reference GTX 760.
ASUS GeForce GTX 760 DirectCU II OC review In this article we review ASUS GeForce GTX 760 DirectCU II OC edition, this particular model comes with a dual-slot DirectCU II cooing solution. That boils down to a silent product versus and more than excellent cooling performance. Inno3D offers the card factory slightly overclocked at some pretty impressive clock frequencies.
ASUS GeForce GTX 780 DirectCU II OC review We test and review the ASUS GeForce GTX 780 DirectCU II review edition. The graphics card comes with a factory overclock and an updated DirectCU II cooler that has CoolTech fans. That would be two silent 90mm fans.
