Everyone has trouble with 290's. If you aren't recompiling cgminer or using one with a pre-modified ADL library you probably won't get them to work.

The 290 has powertune 6, or something like that. The 280 uses powertune 5, which is what the 79xxx series used. Cgminer/bamt are built around powertune 5, so the calls and commands the 290 expects never come. This is why it'll bluescreen out on windows if you press "q" to quit.

280x's didn't work on BAMT for over a month, not unless you recompiled it with the 13.11 beta drivers yourself. The 290 situation is similar, but worse.
