Just trying to figure out why I my reference 290 and 290x can't get past 370Kh/s (on each card, not combined thank god). They are running in ubuntu 13.10 off 14.2 drivers, ADL 6.0, SDK 2.9, and the latest vertminer. Before yous say "it's dem beta drivers!!!!" know that the PTS miner, scrypt, and scrypt keccak have all run fine at decent hash rates. The flags I have are as follows...
290x./vertminer --nscrypt -o stratum+tcp://east1.us.stratum.dedicatedpool.com:3369 * -u 0ut1awed.1 -p x -d 0 -v 1 -w 512 -I 13 -g 2 --lookup-gap 2 --thread-concurrency * 24000 --gpu-memclock 1490 --gpu-engine 1020 --gpu-powertune 20
290./vertminer --nscrypt -o stratum+tcp://east1.us.stratum.dedicatedpool.com:3369 * -u 0ut1awed.2 -p x -d 1 -v 1 -w 256 -I 13 -g 2 --lookup-gap 2 --thread-concurrency * 24500 --gpu-memclock 1500 --gpu-engine 1000 --gpu-powertune 20
Intensity of anything over 13 (even on a single thread) would give me HW errors. Even at these settings after about 340k accepts, I have approximately 1k rejects and 80 HW errors (on each card, give or take). I have also tried dialing back the memory and increasing/decreasing clocks to no avail. As for the TC I tried everything from 10240 to 27000 with pretty much zero change. I setup specfic multiples of the 2816 on my 290x. At 4x(11264) I was getting 355Kh/s. Then at 5x(14080) and 6x(16896) I was back at the 370-375Kh/s average.
Any help would be greatly appreciated.
Also....
GET OFF OF DEDICATED POOL! IT HAS MORE THAN HALF THE HASH AND HAS FOR QUITE SOME TIME.
Why is it still listed as the first pool in OP (with "NEW!" beside it none the less)?With all these coins going down the drain do people really want their investments to continue to be flushed away?
