I get only ~560Kh/s  for 280x Radeon video card.
I know that it is to low here is my config any useful help
will be tipped.

Ubuntu 12
Catalyst Beta driver.

just make a new textfile in that folder and rename it to .bat afterwards and start cgminer with that. cgminer.exe --scrypt -o stratum+tcp://thepool -u userandworker -p password -I 13 -g 2 -w 256 --thread-concurrency 8192
givves me 720kh

Which beta driver are you using? I will post my config later.. I'm currently sitting at ~760-780 on each of 280x's. The 14.1 drivers brought me speeds down. I reverted back to 13.12 and all was well.

I use ubuntu so, so it has
some differences.

It's interesting what you are saying
I'll try to install fresh with the
13.12, I guess it will be faster
than trying to uninstall the driver.

Please publish your config,
I'll try it if I will get
your numbers you defenetly
will winn the prize.

Please try the "thread-concurrency" : "8192 i think it will help also lookup gap 2

[romanticon]

by the way that is the exact model I use:

I have the dual-x as well and can only get 715K out of each.  Try to pull engine clock down to 1035 in config I posted above.  

I have 5 of them and use that config.

I didn't notice that they were the dual-x before I posted the 1050 engine clock in the above config or I would have changed it.

[romanticon]

Try this :

Code:

"intensity" : "13",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "0",
"thread-concurrency" : "8192",

It will take some time
I am installing a fresh image.

[PondSea]

try TC as 8191

[romanticon]

Ok.... here is on fresh install with 13.5 version driver
very poor results

Code:

See this: https://bitcointalk.org/index.php?topic=435438.msg4849281#msg4849281

[backtrackit]

start by lowering lowering thread-concurrency until you hit the sweet spot, might want to lower intensity first to 13, then when you find best thread concurrency up the intensity.

[romanticon]

That is the best I get so far,
the settings that actually matters here is:

"gpu-engine" : "1000",
"gpu-memclock" : "1500",
"intensity" : "13",
"thread-concurrency" : "8192",


if you will help me push it higher
you will get the reward:

I can't believe no one has said this before....

If you're mining on a 280x, and using a TC of 8192 (which you should), you NEED to use "--gpu-threads 2". I've tuned dozens of 280x, with all sorts of settings, and this is always the case.

I've edited your config. Removed some unnecessary settings, tweaked a few others, and see if that works:

Code:

"thread-concurrency" : "8192",
"lookup-gap" : "2",
"gpu-threads" : "2",
"intensity" : "13",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"scrypt" : true,
"gpu-engine" : "1060",
"gpu-memclock" : "1500",
"gpu-powertune" : "20",
"auto-fan" : true,
"gpu-fan" : "0-85",
"temp-target" : "75",
"temp-overheat" : "85",
"temp-cutoff" : "95",
"temp-hysteresis" : "3",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"api-mcast-port" : "4028",
"api-port" : "4028",
"failover-only" : true,
"no-pool-disable" : true,
"queue" : "0",
"scan-time" : "5",
"expiry" : "10",
"log" : "5",
"kernel-path" : "/usr/local/bin"

Thanks crazyates, I do use "--gpu-threads 2" otherwise it's 300Kh/s

--gpu-engine 1050

I don't know why but only precise
 --gpu-engine 1000
give me maximum performance.
Any other value give 100k less
immediately.

[backtrackit]

have you tried worksize at 512?

[romanticon]

have you tried worksize at 512?

Just tested it , same ~703K

raise core clock is what you need now to push it further
