Need help for mining with ASUS R7 260 1GD5

Hi,
this is my first post. I'm new in darkcoin mining, so far I mined bitcoin, litecoin, vertcoin (in that order) for past few years (I think two, but who counts).

I have computer with Asus R9 280x and Asus R7 260.
R9 is working nice, I have 3300 kh/s with sgminer and x11mod kernel (I found link on this forum).
But for R7 I just can't find right config. It refuses to load memclock, and it keeps it 150 MHz.
I had the same situation when I first tried to mine vertcoin with it, and I had to lower the threadconcurrency, to unlock the speed (managed to push it to 118 kh/s, and it is expected performance I found on internet).
I'm not behind the computer that is used for mining right now, but I'll try to write all config that is important from memory:
-memclock 1500
-gpuclock 1150
-shaders 768
-threads 1 (same speed with 2)
-thread-concurrency 6016, 5376, 5017, 3072, 2304 (I have tried all these and memclokc is still 150 instead of 1500)
-memdiff 2
-worksize 256 (tried 128 and 64, didn't help)

Has anyone tried it so far? or some similar card with 768 shaders and 1 GB memory?
thanks in advance
 
Try with -g 2 or -g 1, for my 6850 (1 GB ram) worked -g 1, otherwise I was getting 150 khash/s instead of 1020 khash/s
 
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx DISPLAY 0
sgminer -k x11mod -o stratum+tcp://mining.darkcointalk.org:3333 -u fra55.1 -p xxxx -I 18,17 -w 128,256 -g 1,2 --shaders 960,2048 --no-submit-stale --lookup-gap 2,2

First values (I 18, w 128 etc.) refer to a 6850 Gigabyte, the second to an Asus 280x
I get 1 mhash for the 6850 with undervolted and underclocked frequencies

Just to make update on this, and to close the thread, after update from 13.x to latest 14.14 drivers it started to work just fine. Aprox 1000 Mh/s
