295x + 290x Keep throttling down, even though not reaching temp?

[pugheaven]

Mmmm, not noticed this before, but somethings changed. I've got afterburner clocking my 3 cards all at 1025/1300 nice and easy and playing BF4, however, it's basically running all the cards at slower than I want... and throttling the core's down yet all temps are under 60C... 40-60... what's going on as it's wrecking my game?

Any ideas?

What is your psu and which drivers?

 

[labcoattech]

What CPU are you running? sounds like something is bottlenecking your card.

CPU bottleneck would just reduce load, it shouldn't affect clock speeds.

My money on PSU

Amusing you have upped the power limit to +50% on AB already, then I would try using the last catalyst drivers instead of the latest crimson ones to see if its a driver issue. I know there have been a few problems with crimson dropping clocks for some people.

 

[Confused Stu]

Have you got any kind of FPS limiter in place? Just wondering as the cards will only work as hard as they need to so if they're hitting your FPS limit then they'll clock down.

Deffo a possibility. With three of those monsters in there, even 120 fps limit would not let them stretch their legs on most games

Since you do not have any major oveclock remove AB completely.

Uninstall AMD drivers. After the reboot, then use DDU to wipe out everything AND the settings. Put the 16.3 or newer Crimson drivers. Go to overdrive. Put 50% power and apply your 1025 overclock.

Assuming you have PSU capable enough to handle the power consumption. (you need 1200W gold or Platinum of good quality brand.).
