It looks like a full time job making that card to work properly.
Card screams for water block or custom air cooling.

I'm not sure if this is a bug in the software, or whether there is some funky things going on with the card's themselves, but voltages seem to set themselves where they please. My 2 cards have fairly comparable ASICS qualities, one is 78% while the other is 74%. Setting voltage to 1.25v on them = 1.031v for 78% ASIC and 1.063v for the 74% ASIC card. Here's another weird thing I noticed, the card running 1.063v actually pulls 5w less at the wall while hashing at the same settings. Seems like the higher ASIC card actually has more leakage. Increasing clock speed will also increase the GPU's voltage by it's self. Let's say for example: 1.25v set 1000mhz clock = 1.063v after vdroop using gpu-z. Up the clock speed to 1100mhz and now gpu-z measures 1.120v or so. To get back to 1.063v,youll have to lower voltage in GPUTweak to 1.15 for example. Those aren't actual numbers, but you get the gist of it. What's worse is that both cards behave differently!
This is really weird, higher ASIC usually have better quality output and you can lower the voltage lower compare to others and thus saving more energy. At least thats how it works for my 4 GPU...
Yep, higher ASIC should mean less leakage. Who knows.
Hoping to get somewhere with 2 threads today.
Well CGminer is set to keep them at max 80c, so they're both at 78c right now but the 1.063v card is running it's fan 200RPM higher to keep it there so it is giving off a little more heat.

Having a really hard time finding proper settings. I thought I might have a bum card so I picked up a second 290x today, same results. Right now my best result is 850KH/s @ 885/1250 TC 32765 -g 1. I tried duplicating the settings in the OCN thread Ivan linked, but they don't work for me.
885mhz is super slow for the core...up that thing in the 1000-1100 territory and man up :p
I still prefer stock clock for my GPU although its not 290x, but I find it more energy efficient.

You really think I didn't try that before going out to buy a second card to make sure the first wasn't a dud? These cards are very weird. Might be that cgminer isn't fully compatible, I have no idea what to think. I spent about 12 hours fucking around with both today with -g 1. My best result so far is 885kh/s @ 920/1500. Going to try and get -g 2 working properly tomorrow.

Did you try using GPU-thread 2 instead of 1?
Yes, and I think figuring out -g 2 will be key on these cards. Speed jumps between 830 to 1150kh/s with 2 threads, but averages about 850kh/s. In comparison to 7970 which could use just about any TC settings and absolutely needed -I 13 for 2 threads, these cards will spit out nothing but hardware errors with TC any lower than 22500 or so. Running -I 13 is no good, about 500kh/s max. These cards need -I 18~20 to get anywhere with either 1 or 2 threads.
RandomQ,
Have you tried to go higher then intensity 13? Also is the card voltage locked? I'm thinking about ordering a couple myself.

No, I've always run my cards at I13
I'm pretty sure its voltage locked, But not 100% afterburner needs an update its still showing is as a 7900 series
Not locked...you have to use GPUTweak, a modded version for voltage unlock. You can also flash other modded bioses, for higher voltage which isn't smart for mining though.
Be warned, Asus GPUTweak is complete garbage compared to afterburner. While normally buggy and just about useless, this hacked version is even worse. Don't get me wrong, I'm extremely grateful that it's available, but it can be a real pain in the ass.

Preliminary results: Took an hour and 15 minutes to get the drivers to install. 
Dont they come together with drivers???
If he had an nvidia driver before it's a pain...but not too terrible.

Haha, thanks!
Y no gpu waterblock?
(I have the same case but I modded it and rotated it...the front is now the bottom)
I'm still looking around at options for waterblocks, don't think any will fit without modding slightly. Think I might give the heatkiller a try, looks like the layout is right, but capacitors are in the way. I may be able to mod the block where it interferes, maybe! EK had my cards listed as compatible for a while, but then they changed it a few days after I got these...
I love these cases! I've built a few with this case, it's got nearly everything and it's easily moddable too
Definitely...love the cm 690 II as well. Mine looks like a Silverstone FT-02 these days xD
You won't find fullcover blocks for those me thinks, it's better to go ref gpu with AMD in general, specially if you can get wc.
I'm gonna grab a 290 non x and wc it, got a Glacer 240L and an i7 3820 atm.
Haha, thanks!

My cards appear to be voltage locked. 7970's run too damn hot to worry about voltage
They dislike anything more than i13 running two threads. Will handle i19 rather well as a single thread, but not optimal. Anything higher than 13 will h/w error like crazy with two threads.
Here's some power consumption, but this is my "best gal" computer doing many things that a miner wouldn't need to do.
