Overclocking the Gigabyte GTX 1080 Xtreme Water Force

Our maximum achieved overclock on the Gigabyte GTX 1080 Xtreme liquid-cooled card was stable at 2100.5MHz, peaking at 2151.5MHz on occasion. That had the card operating with an offset of 100MHz on core, 400MHz on memory, and the maximum +50% power. The card's memory clock settled at 11GHz effective.

With a 100% voltage offset, we lost stability within a few minutes of testing, though the action did allow momentary increases in core offset. This offset was reduced and removed in later validation, as we found the OC performed better without it. A voltage offset eats into TDP, anyway.

Here's the OC stepping table.

Our own 1080 Founders Edition Hybrid custom mod is still the best overclocker we've tested from this generation, but all the board partner cards seem to be lucky if capable of achieving a 2100MHz clock-rate.

As shown in the other OC stepping tables, the EVGA card managed a higher stable overclock at 2151.5MHz with a peak at 2164MHz. MSI's Sea Hawk maxed out at a 2050MHz stable core clock, with peaks at 2126MHz in our test. The MSI card runs a reference board, though, and is more simplistic in its power and thermal design than the Gigabyte and EVGA solutions.

Overclocking FPS Impact

The FPS charts post similar results to previous OC attempts with the EVGA FTW Hybrid and MSI Sea Hawk X. We're not seeing any major differentiation between the cards with FPS from overclocking, something of a trend of late with this generation of high-end GPUs.

Continue to the final page for the conclusion.

Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.
