R9 390 core clock stays at 300 Mhz.

Post by streetwolf »

Hi guy...

Thought you could help me out on my problem. I got a new Sapphire R9 390 a few weeks back. I never realized until today that Powersaver isn't working. My Core Clock stays at 300 Mhz. even when the GPU is pegged at 100%. The Memory Clock does go up when needed. My previous card, HD7970, the Core Clock would always go into high gear when called for.

According to CPU-Z under the graphics tab I have two performance levels 0 = 300/150, 1 = 1040/1500. So why does the Core always stay at 300?

I ran DDU in safe mode then reinstalled 15.10 with no change. I even ran DDU and let Windows install their AMD drivers and still the same thing.

With your knowledge of AMD 'stuff' is there anywhere in the Registry or elsewhere where all of this is controlled.

Do you have any youtube / video open and running at the same time?
300Mhz is usually the clock when hardware video acceleration is used.

I ordered a replacement card from Amazon. I also put back my HD7970 and that works fine. Another thing I noticed with the 390 is that profile.xml didn't have some values filled in like the core clock. Wonder if the default profile was the problem. I'll find out tomorrow when I get the replacement.

The new card is working great! No more locked at 300 core. It ups both clocks to my max values when I run graphics stuff. At idle it returns to 300/150. I noticed that these changes are faster than my HD7970.

As I didn't look at my clocks until a week after I received my last card I will be keeping an out out on my clocks with this card.
