I did try your settings, and they resulted in similar power consumption yes - but only 272khash.
Perhaps you have "trained" your cards into high performance?
At which (approximate) settings have you had them running in those 6 months, before you reinstalled and readjusted? And which power consumption and temperature?
If only I would get even close to 500, it would be fantastic.
Amazing. With that you could even mine for Danish electricity prices :-)
For a while I had Tc = 10240, 11264 on my 7970 and 7850 - because that was the max multiple of shaders that didn't result in kernel errors.
But then very often, both cards would just not start at full power, always one of them hovering at 30khash.
It took me ages to find out this solution, and that it is not a lack of power (I have funny cabling in my old machine):
Tc = 8192, 8192 works perfectly. It's only using 1072MB of the 3GB of my 7970, and I don't understand that - but it's fine.
hmmm ... we really need to find out how you are able
to drive your cards up to such high khash for so little
clockspeed = temperature = Watt = electricity costs.
Let's save half of the electricity of the worldwide GPU grid!
I would point out that 6 month ago i could not get these value.
THAT is really interesting - and perhaps an explanation?Perhaps you have "trained" your cards into high performance?

Recently I reinstall the rig with new drivers and cgminer 3.7.2.
Which catalyst drivers?Yes are my value (when i see them i did't belive myself).
My rigs are 3x VTX HD 7970 X-Ediction and 4x Sapphire R9 280x Dual-X.
The "U:" not sure what is....it is reported when u are mining and click "G" for modify Video cards setting.
try to put Engine to 900 and Mem to 910, then you go up with Mem 920, then 930 ecc...you should find a spot where you are about 600 Khash/s.
In the photo I' m not using 900 how engine but a little more....900 is just a point I use to start.

280x rig is about 760 Watt
7970 rig is about 600 Watt
