Thanks to all concerned (too many posts to quote).
Took my MSI R9 290 from 3.7 to 4.99Mh/s on x11.
Used the method of extracting (but not installing) the 14.6 AMD package, copying the 8 required files from the AMD/AMD-Catalyst-14.6-Beta-V1.0-Windows-May23/Packages/Drivers/Display/WB6A-INF/B172153 folder and putting them in the sgminer folder with any previous bins removed before starting up the miner.
Getting WU 0.069 and 0.7% rejects with 1010 core, 1300 mem, intensity 20 on trademybit pool. Gonna let it run for a few hours before tweaking some more.
Cheers again
