Like i said before radeon 7990 is much better than R9 270 even R9 290, why didn't you bought a 7990?

because i have some computers with 450w power supply
so take one 270 and later buy 3 more

also 270 is 290 half price and same for speed it s half of an 290

so it s better of with 2x 270 than 1 290
also if it's broken , your 290 break nothing left, 1 270 break you still have 1

You do something wrong. Please try to install driver for AMD 14.7 RC3, delete all bins from sgminer folder, get modified kernel from pallas (Opensource Kernel (v1)) https://bitcointalk.org/index.php?topic=779598.0 and run again. You'll get something like 10 Mh from each of your R9 270 or ~ 1 DMD/day from every card. With current difficulty it's better to mine solo.

are you sure 10mh with 270 ?(not 270x)

i have driver 15.10 Beta i downlaoded the sgminer sgminer_diamond_v4.1.0.zip

i gonna try , thank fro the information

i tryed, driver 15.10beta sgminer 4.1.0 i downloaded the groestlcoin-v1.cl renamed to diamond.cl
deleted diamondPitcairnglg2tc10688w256l4.bin

but no change i have 4.7 mh

and it s worse i think groestlcoin.cl is not same as dimaond i ve got lot of rejected shares

Did you....
1.) Copy the name of your Original .bin file
2.) Rename the Optimized .bin file to the name of your original in step 1
3.) Delete (move) your original .bin file
4.) Copy/Move the the Renamed Optimized .bin file into your miner directory?

You should try 14.6 or 14.7 RC3 driver with pallas kernel. Not 15.10. Than you can set memclock to 150 and gpu-engine to 1150 for max performance and low heat http://i76.fastpic.ru/big/2015/1103/e2/3aaebad1dab0df98de81fb6bb5fab3e2.png - It's 2 HD 7850 on 1110 MHz
