AMD/ATI Pixel Clock Patcher

[alex47]

Hi!
This does not work for me. I wanted to create a custom resolution for my new monitor. Wanted to do the 1350 trick with lightboost.
It does not let me do it on 120hz.
On 110hz it works fine because its just below 330mhz.
Does this only work with CRU?
I tried it with the AMD driver custom resolution.
Monitor: BenQ XZ2411Z
GPU: R9 390
Windows 10
