Custom Resolution Utility (CRU)

[Eagle]

Hi,

I have a R295x2 and I managed to buy Asus ROG PG278Q before I did some research. So I'm kinda stuck here with 85hz at maximum, but then I found this utility, but when I try to add it still flickers when I add the custom settings for 144hz. I have tried to AMD/ATI Pixel Clock Patcher before I applied the custom settings, anyone have any ideas?

Here are the settings I have applied in CRU.

Horizontal:
Active: 2560
Front Porch: 8
Sync Width: 16
Back Porch: 16

Vertical:
Active: 1440
Front Porch: 1
Sync Width: 1
Back Porch: 7

Pixel Clock: 542.58 MHz
