Not sure if I'm reading things incorrectly, but I see there is a optimized groestl kernel for SGMiner to help boost mining hashrate for certain AMD cards. I am running SGMiner 4.1 with the optimized kernel from Pallas, which I have replaced both the diamond.cl and groestlcoin.cl files with, but it appears this has made no difference with my hashrate.

I'm testing on a 280x running at stock settings, and am averaging 6.7Mhs, while I see others posting much higher rates with 280x and even the 270x. Am I missing something here? I've deleted the .bin files so new ones will be created, and I'm running the following batch file parameters for it.

sgminer -k diamond -o stratum+tcp://dmdpool.digsys.bg:3333 -u xxx -p xxx --xintensity 300 -g 1 -w 256 --lookup-gap 0 --thread-concurrency 8192 --difficulty-multiplier 0.0039062500

Also since I'm testing on Danbis pool, but POW for Diamond is not active yet, does anyone know what the pool is mining currently? I'm guessing its Groestlcoin itself.

FYI: testing/mining on Danbis pool is not showing any rejects for me.
