Waiting to receive 5 more risers to get to 9x R9 290 on this rig (~7500 KH/s for ~3000W).
2 MOBO and will be 3 PSU.
Cheap wooden prototype case.
Will stack 3 like this, hopefully not torching the place

Did you have trouble getting your R9 290s running stable? I have nothing but trouble with 4x even with the latest drivers. BAMT won't go into Xorg with more than 1 card and Windows crashes as soon as I get to 3. 280x's work fine...
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.
