Specifications and Design
When the GeForce GTX 1080 Ti launched last month it became the fastest consumer graphics card on the market, taking over a spot that NVIDIA had already laid claim to since the launch of the GTX 1080, and arguably before that with the GTX 980 Ti. Passing on the notion that the newly released Titan Xp is a graphics cards gamers should actually consider for their cash, the 1080 Ti continues to stand alone at the top. That is until NVIDIA comes up another new architecture or AMD surprises us all with the release of the Vega chip this summer.
NVIDIA board partners have the flexibility to build custom hardware around the GTX 1080 Ti design and the EVGA GeForce GTX 1080 Ti SC2 sporting iCX Technology is one of those new models. Today’s story is going to give you my thoughts and impressions on this card in a review – one with fewer benchmarks than you are used to see but one that covers all the primary differentiation points to consider over the reference/Founders Edition options.
Specifications and Design
The EVGA GTX 1080 Ti SC2 with iCX Technology takes the same GPU and memory technology shown off with the GTX 1080 Ti launch and gussies it up with higher clocks, a custom PCB with thermal sensors in 9 different locations, LEDs for externally monitoring the health of your card and a skeleton-like cooler design that is both effective and aggressive.

Out of the box EVGA has overclocked the GTX 1080 Ti SC2 above reference specs. With a base clock of 1557 MHz and a GPU Boost clock of 1671 MHz, it has a 77 MHz jump on base and an 89 MHz jump on boost. Though moderate by some overclockers’ standards, that’s a healthy increase of 5.3% on the typical boost clock rate. The memory speed remains the same at 11.0 Gbps on 11GB, unchanged from the Founders Edition.
I’m not going to walk through the other specifications of the GeForce GTX 1080 Ti GPU in general – I assume if you are looking at this story you are already well aware of it features and capabilities. If you need a refresh on this oddly-designed 352-bit memory bus behemoth, just read over the first page of my GeForce GTX 1080 Ti launch review.

Hardware/Software Picks of the Week
The new EVGA GTX 1080 FTW2 with iCX Technology
Back in November of 2016, EVGA had a problem on its hands. The company had a batch of GTX 10-series graphics cards using the new ACX 3.0 cooler solution leave the warehouse missing thermal pads required to keep the power management hardware on its cards within reasonable temperature margins. To its credit, the company took the oversight seriously and instituted a set of solutions for consumers to select from: RMA, new VBIOS to increase fan speeds, or to install thermal pads on your hardware manually. Still, as is the case with any kind of product quality lapse like that, there were (and are) lingering questions about EVGA’s ability to maintain reliable product; with features and new options that don’t compromise the basics.
Internally, the drive to correct these lapses was…strong. From the very top of the food chain on down, it was hammered home that something like this simply couldn’t occur again, and even more so, EVGA was to develop and showcase a new feature set and product lineup demonstrating its ability to innovate. Thus was born, and accelerated, the EVGA iCX Technology infrastructure. While this was something in the pipeline for some time already, it was moved up to counter any negative bias that might have formed for EVGA’s graphics cards over the last several months. The goal was simple: prove that EVGA was the leader in graphics card design and prove that EVGA has learned from previous mistakes.
EVGA iCX Technology
Previous issues aside, the creation of iCX Technology is built around one simple question: is one GPU temperature sensor enough? For nearly all of today’s graphics cards, cooling is based around the temperature of the GPU silicon itself, as measured by NVIDIA (for all of EVGA’s cards). This is how fan curves are built, how GPU clock speeds are handled with GPU Boost, how noise profiles are created, and more. But as process technology has improved, and GPU design has weighed towards power efficiency, the GPU itself is often no longer the thermally limiting factor.
As it turns out, converting 12V (from the power supply) to ~1V (necessary for the GPU) is a simple process that creates a lot of excess heat. The thermal images above clearly demonstrate that and EVGA isn’t the only card vendor to take notice of this. As it turns out, EVGA’s product issue from last year was related to this – the fans were only spinning fast enough to keep the GPU cool and did not take into account the temperature of memory or power delivery.
The fix from EVGA is to ratchet up the number of sensors on the card PCB and wrap them with intelligence in the form of MCUs, updated Precision XOC software and user viewable LEDs on the card itself.
EVGA graphics cards with iCX Technology will include 9 total thermal sensors on the board, independent of the GPU temperature sensor directly integrated by NVIDIA. There are three sensors for memory, five for power delivery and an additional sensor for the GPU temperature. Some are located on the back of the PCB to avoid any conflicts with trace routing between critical components, including the secondary GPU sensor.
