Overclocking the new Alienware 15 R2 (Late 2015) with NVIDIA GeForce GTX 980M

You’ve probably already seen our in-depth review of the latest 15-inch Alienware R2 (Late 2015), and how its cooling system manages the high load in our synthetic and real-life gaming tests. Since we were more than satisfied with the temperature results, we decided to slightly overclock the GPU and see what we could get as an advantage in terms of frames per second in our gaming tests.

Let’s check the temperatures at normal load first, using 720p HD video. The CPU runs at around 40 °C and the GPU ~55 °C. This is how the temps look on the outside.

Even after 2 hours of 100% CPU+GPU load (1h of 100% CPU + 1h of 100%  CPU+GPU), the GeForce GTX 980M remained below 70C. Of course, that’s just a stability test and chances are you won’t be able to tax your Alienware that much with real software.

We canceled the synthetic CPU load and clocked the GPU by 13% (Core) / 5% (Memory), which was enough to provide up to 10% of FPS advantage in the games below.

Default clock +13% Core Clock / +5% Memory Clock Difference
Tomb Raider (FHD, Ultra) 68 fps 75 fps +10%
Metro: LL (FHD, Max) 40 fps 43 fps +8%
Shadow of Mordor (FHD, Ultra) 68 fps 72 fps +6%

Naturally, we ran a stability test as well – 30 mins at 100% GPU load. Alienware didn’t indicate any issues at all – GTX 980M ran at 64°C.

How did you overclock the GPU and RAM? I have downloaded MSI afterburner. Please explain the ratios like increasing the voltages and changing the frequencies steps.

I have the same laptop with GTX 970M
