Overclocking
On the previous page, we learned that our video card is averaging around 1877MHz while gaming. Now we can overclock it and see how much higher we can get! We are using the GIGABYTE AORUS Engine software and our ambient temperature in the room is 70F.
Highest Stable Overclock
Here is the GIGABYTE AORUS Engine software and this shows the highest overclock we found playable. We managed to turn up the Power Target to 120%. In addition, we were also able to turn up the GPU Voltage to +100. We did set the fan to 100% speed to make sure we could overclock as high as the GPU would go. Note that at default operation the fan already spins up to 73%, so it is quite high to begin with.
ith all this in play we were able to push the GPU Boost to +120 and the Memory Clock up to +498. There seems to be a bug with the memory clock speed reading, while it does say 14.5GHz here, it actually is set at 15GHz at +498, from the default 14GHz.
Here is a graph that shows the new overclock in comparison to the default clock speed. You can see that the overclock is providing a large difference. The average of the overclock is 2061MHz! Therefore, compared to the default average of 1877MHz a 2061MHz average overclock is 184MHz higher or a 10% overclock. The clock speed seems to stay between 2040-2060MHz while gaming.
Then, on the memory side of things as we indicated the actual overclock is at 15GHz versus the default 14GHz. This gives us a new memory bandwidth of 360GB/sec versus 336GB/sec (15,000 x (192/8)).
GPUz
GPUz shows the correct memory frequency and bandwidth and our new GPU Boost speed. With the fans at 100% the GPU temp is 64c, maybe a bit warmer than we’d expect with fan speeds that high considering the default speed runs at 68c. We are definitely pushing the envelope on the TDP and our Power Consumption has gone up to 152.8W versus 127.7W at default.
Our final highest overclock is:
GPU – 2061MHz
Memory – 15GHz
