According to setting posted here ppl are getting the hashrates of 180kh/s?

During the last n Factor I was mining at the speed of 340 kh/s which is think was par for the course.
For this new n factor I use the settings below and get a bunch of HW errors ... I have to lower my intensity to 12 to get ZERO HW errors and then I only get 72kh/s which os obviously not good.

POSTED or POOL.CACHECOIN.NET:
R9 290 8GB RAM (1040/1400), expected hashrate about 180kh/s
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

There has to be something more to the settings above ! can some please be UBER Specific and post absolutely every setting for an R9 290.... also my thread concurrency does not go over 30592, how canyou possibly get it at 45000?
I am mining with a GIGABYTE R9 290 OC and Sapphire r9 290 Tri-X, Windows 8.1, 8 GB of RAM
