tried on 6950 (unlocked shaders), 6970, 5970 in a pc (H81 BTC PRO,RAM 4GB, G1830, W64, USB3 powered PCIE risers).

switched the driver from 14.4 to 14.6, after switching the driver, tried Lasybear's sgminer released on 2014-06-03 (successfully used by me before) and sgminer released yesterday by djm34 and got about 5% decrease on both miners in mining performance of x11 based coins.

Haven't used DDU this time for the driver update, used native AMD uninstaller & installer (felt lazy to restart pc into safe-mode because of lack of an attached monitor at the time and non-operational Teamviewer in the safe-mode). Checked driver version (14.2) in the device manager and it does correspond to catalyst 14.6 package.

Should I wait for an update of the the sgminer with better support of 6XXX and 5XXX series, thou some people in the thread report slight increase in performance using the same adapters and the method described in the thread ?

Or should I re-install (using DDU) the 14.6 driver first ?

Any comments are welcome.
