AMD Driver capping GPU clock

So recently I have been having problems with my GPU or so I thought it turns out it's something to do with the Crimson driver from what I can tell. I have tested the GPU and it seems to run really well without any problems just for some reason the Crimson driver is hindering its performance. Or at least it's my take on the matter.

So when my GPU isn't being used For all intents and purposes lets say gaming the GPU clock sits at 300MHz. That's normal its expected most modern GPUs don't run at full performance all the time to preserve the GPU save power etc. However here's the problematic part, when I'm playing a game for example let's say Overwatch. My GPU clock goes up to 400MHz and stays capped at that speed. The GPU clock can go up to a maximum of 900MHz and is set to do so. However it doesn't. Sometimes if I leave my computer idle for a while sometimes it fixes itself and when I launch at game my GPU will run at full pelt on 900MHz which is required in order to get the best performance possible so that I don't get low FPS.

I have tried a number of fixes including checking to make sure the GPU itself is fine and works fully which it does. Completely uninstalled all AMD drivers using the AMD cleanup utility, reinstalled the drivers restarted the computer and it was fixed of course after shutting down my PC for the night and starting it back up in the morning the same problem has occurred all games capped at 400mhz even though the GPU is free to run up to the maximum clock speed which is 900MHz. I have also made sure that my power settings are not set to power saver it's set to High Performance. I would really love to get this fixed because I hate having to wait for this thing to sort itself out. I also don't want to keep uninstalling and reinstalling the driver every time I want to have a gaming session.

Specs
CPU: Intel Core i7-3770 CPU @ 3.40GHz
GPU: AMD Radeon 7750 1GB
RAM: 16GB
MOBO: MSI motherboard (not entirely sure specifics) ( It's decent it works fine)


Im looking for temporary fix right now because I going to ditch this card in favor of a GTX 1080 this January
 
well I do know the latest driver I use on my 7850 is 13.12 the later ones just sucked and I go right back to it and stay on it seemed all the later drivers all ways had some kinda of little issue like flicker or just black screening , just all ways something not quite right that I never get with 13.12 and still use it today with out issue . seems to me it was the last solid driver for a hd7000 series card

good luck

What? can you even read my GPU is capping itself for no reason causing me to get low FPS in games I would normally get high FPS
 

And I guess your GPU ist capping itselfe at the fps your monitor supports because everthing above is only a wast of energy. If that''s not the case, post the fps you get.
 
thing is the newer drivers are more geared for the latest cards and what AMD maybe trying to ''fix'' from there new cards maybe affecting your old card in a bad way ?? like the power issues they report with the new RX cards that ''fix'' may hinder yours as well .. why I feel the 13.2 driver was the last solid driver for the hd 7000 series

good luck

It has nothing to do with capping the FPS to what my monitor supports because it isn't doing that the driver is capping my GPU clock for no apparent reason on all games. some times it doesn't and the GPU works at full power and my FPS is amazing. For example right now my GPU speed is locked on 400MHz limiting Overwatch to around 30-40 FPS making it unplayable but last night when I did a clean install of the driver and made sure everything was set correctly anywhere between 50-90 FPS.
 
loks like go NVidia ? not ot say there drivers lately are any better like one guy put it ''seems there braking as much as they fix '' ?/

I got a gtx 980ti and still use older 355.82 on it because of that ?? may read up and some NVidia driver release feed back threads as well

Did you check the temperature when it happens?

Current temperature 47°C its now capped at 400MHz again even though it was running at max earlier for no apparent reason. Can't even get my GPU to run at a lower than 400MHz
