Overclocking

Before I finished up testing on the R9 380 Gaming 2G I had to see how the card would overclock as well. To do this I split the overclocking into three parts, GPU, Memory, and then both together. On each I slowly bumped the overclocks up and documented what happened below. The goal here isn’t to set a world record so I’m not typically changing voltages (if I do I note it). The goal is to be able to compare from card to card how they overclock and also have an idea of what kind of performance increase you will actually see with an overclock. For this card I started out on the GPU at the stock clock to get a baseline. From there I bumped things up until I ran into a drive crash at 1150MHz. From there I tried a few more smaller changes to get our peak overclock of 1130MHz. Next I went through doing the same thing on the memory side. This time around I actually peaked out the software I was overclocking with before running into an issue. Lastly I paired up our GPU and memory overclocks to see if they would run together, sadly I ran into a driver crash the first time. I turned the GPU clock down slightly and gave it a second go successfully. In the end we went from an FPS of 51.74 to 59.87, not a bad increase for free.
