With the launch of Radeon R9 Fury X graphics card, plenty of overclockers were quite keen to get their hands on one and check out the overclocking potential and scaling but were quickly disappointed to find it locked. While conventional overclocking, without voltage increase, yielded a 10 percent increase in clocks, it appears that even with higher voltage, the R9 Fury X is not that good in overclocking.

Our good friend from Techpowerup.com, W1zzard, which is also a guy behind the popular GPU-Z software monitoring tool, has managed to work around AMD's locks and push some more voltage to the Fiji GPU, and it was quite a hard task.

By raising the voltage in 24mV steps from stock, and checking out a maximum stable GPU clock with each push on voltage, W1zzard managed to get to +144mV for the GPU, which raised the GPU clock to 1215MHz and core voltage of 1.35V. This also significantly raised the system power draw to 575W, or 125W more than with stock settings, and pushed the temperature of the VRM up to 95°C, which is pretty high considering that the Fury X is liquid cooled.

While these results might sound impressive, the gain in real world testing was quite disappointing, getting about a 3FPS average increase. Even the additional overclocking on the GPU did not give any better results, as memory clock of 560MHz raised the total FPS by 1.6FPS.

According to W1zzard, the safe voltage overclock is +40mV. He also noted that he will soon release a software that will allow users to raise the voltage on Fury X graphics cards and new GPU-Z version should let you monitor that voltage.
