Okay so here's the update. I did a full un root return to stock, wiped data, and re rooted/ installed a game and it happened again. Frequencies reverted back to an even lower 1.4ghz almost instantly. I'm at a loss. It only happens when I start up a game. And I know it didn't do this at one point but I don't remember what was different or what i changed from back then.
I'm not knowledgeable about games and your inability to overclock your device.
I am quite clear on the process of elimination and gauging your ability to accomplish a task and rule out the root cause.
For now, stock, rooted, DeOdex rom, simple overclocking app, and kernel capable of doing same.
My suggestion stands.
No games, tell us if you're able to overclock your CPU at all.
