Tweaking R9 290 scrypt mining - cgminer

[JohnnyDaMitch]

Rejection rate is like 4.5% and this is because of that 290. If you take this out of the picture the rate would be 1.2-1.5%

I am finding that for given settings this varies somewhat from card to card. Some useful tips on lowering rejects here: http://www.reddit.com/r/gpumining/comments/1sxt7j/7950_cgminer_intensity_reject_rates/
