GPU stuck in lower power state

Hello,

so recently a new issue appeared. Basically the GPU gets stuck in a low power state or drops to it while in game.

What I mean by that is that the GPU suddenly clocks down or can't clock above 501MHz when playing games.

Sometimes it's stuck from the beginning right when I started the game, sometimes it drops down to 501MHz while playing games.

It's especially noticable because the games start stuttering.

My PC specs:

Intel i5-4690(4 x 3.5-3.9GHz)

2 x 4GB G.Skill DDR3-1333 7-7-721

ASUS Sabertooth Z97 MK II

Club3D HD7970GHz RoyalAce(1100MHz core clock, 3GB 1500MHz VRAM)

BenQ XL2730z(2560x1440@144Hz, connected via Mini-DP to DP cable)

 

The issue happens in all games I play, namely Battlefield 4, Killing Floor 2, Quake, Counter-Strike: Global Offensive, etc.

Temperatures are okayish, just recently cleaned the heat sinks. GPU usually 40°C idle and about 87°C while playing. CPU is at 32°C idle and 45°C while playing.

 

I could be wrong, but I think this started with my new monitor. I previously had a Samsung SyncMaster P2450 1920x1080@60Hz which was connected via DVI.

 

EDIT:

I just changed the thermal grease and except for a few degrees celsius less there is no change in behaviour. Just tried it in BF4 again and maybe 10 minutes into the game it clocked down to 501MHz while the gpu was at around 86°C
