GTA V ERR_GFX_D3D_INIT error

Hi guys,

Since I bought this GPU, the ASUS Radeon R9 285 Strix OC 2GB, I have been getting the ERR_GFX_D3D_INIT error. It occurs during gameplay and it's totally random as of when it occurs.

I have tried literally all solutions and I still keep getting the error. My GPU temps are about 73ºC/163F.

Rockstar Support said and I quote:

"The ERR_GFX_D3D_INIT message appears when there are issues with the core voltage and/or VRAM clock speed. In order to correct this issue, please contact your video card's manufacturer in order to receive support for the settings."

I have contacted AMD support but I still haven't got any reply... so I decided to try my luck here.

My specs:

GPU: AMD Radeon R9 285 Strix DirectCU II OC 2GB (installed on PCIe 3.0 x16 with latest 16.1 Crimson driver) 

CPU: Intel Core i5 4460 3.2 GHz 

RAM: 8GB 

Motherboard: Asus Z97-K/USB3.1

PSU: Nox NX650W

OS: Windows 10 Pro 64-bit (installed on a Kingston V300 120GB SSD)

This is my GPU on Game Debate: http://www.game-debate.com/hardware/index.php?gid=2632&graphics=Radeon%20R9%20285%20Asus%20Strix%20OC%202GB%20Edition

I must admitt I play with more VRAM than the game's slider advise me to use but using MSI Afterburner my VRAM never goes above 1800MB even if the game slider shows I'm using 2400MB...

Sometimes I also get black screen followed by a "No Signal" on my monitor and I have to hard restart my PC. Can anyone help me so that I can finally play the game decently? I spent nearly 400 euros this Christmas buying upgrades for my PC for nothing...

Thanks in advance.

Update: this time it didn't show the error but the "No Signal" appeared. After more than an hour of gameplay the screen froze then the "D-SUB No Signal" appeared and the music kept playing until a certain point, then I hard restarted the PC when I finally stopped hearing anything, music whatsoever.

Any idea what might be? And is this related to the ERR_GFX_D3D_INIT error?

Thanks in advance.
