God fucking damnit /g/, APUs are shit.

Well no shit, they're poverty tier products after all.

have you tried haskell? that might be the solution

I remember when they were shilling the whole crossfire thing with APUs and discrete GPUs. Looks like that whole thing fell through, maybe Zen will have something though.

I dunno maybe the gpu cores cant handle anything over 3ghz from the cpu.

The story with this was that you were limited to bargin bin GPUs, like the 7550 or some other garbage.
And when you actually did buy a garbage card to crossfire, it actually put performance DOWN. The dual performance was actually worse than the 7550 by itself.
That shit was a fucking disaster.
APUs are okay if you are sure you will never need more graphical power. But if you think you'll ever need a GPU upgrade they're a horrible idea.

No you idiot, ut's most likely the VRMs getting hot or some gay TDP lock down kind of deal from AMD. Probably the former.

>>57771851
No you idiot, its the iGpu throttling from heat. Very well known and common issue on the 7870k

>>57770098
Use Stilt's Devastator Powertune to remove APU's power limiting

Does that work with kaveri?

Nope, my temps are just fine. In fact a ~40°C thermal margin is pretty good for an AMD CPU stress test. CPU throttling only occurs when the iGPU is under heavy load despite having ~30°C thermal margin.
This is all being done on a stock wraith cooler btw.
Anyway at least I know my CPU can hold 4.2Ghz without a liquid cooler at 1.3V so I got that going for me which is nice.

Don't know. But there is also this for kaveri
