Nop, I'll try that.
The best miner is the one listed on the first post, or there is one update somewhere else?
For Windows and Linux Bamt.

Hmmm, I also had some unexpected things with cgminer with different cards on one rig till I dismounted the older card.

have you tried to disable one card?

screen -dmS sgminer /home/sph-sgminer/sgminer --gpu-fan 63 --gpu-engine 1120,1000 --gpu-memclock 1500,1250 --gpu-powertune 19 --intensity 20,18 -k darkcoin -o 85.131.127.26:7903 -u XavaNMidPmofBUt4RWLf6YHhNDUNA7TjY6 -p 1

Here are my parameters.
The first card is the 290.

The temperature is 63°.

Strange, maybe are you using auto-engine?
Maybe the card throttle down cause of temperature target?

Thanks, both of you.
Interesting to see totaly different settings.

You use the Sph-sgminer of the op?
I use it on bamt, and I think I found my stability problem: with intensity 21, after 5 minutes, my hashrate decrease quickly. So I'm surprised you are stable with such high intensity (classic intensity?)
I managed to reach 2.5 using intensity 20, but 1120 gpu-engine, not sure if my card will not fall Sick.
Does the thread concurrency matters for that currency? I did not put anything in my configuration file.

I just noticed my Hash went from 2.5 to 2.3 after 10 minutes...so same 0.2 drop again, I really don't understand where it came from.

No, this are my current settings for the r9-280x.

Thats my settings for the 290:
--no-submit-stale -I 22 -g 1 --thread-concurrency 16000 --lookup-gap 0 -w 256  --auto-fan  --gpu-fan 80-100 --gpu-powertune 2  --gpu-engine 1000 --gpu-memclock 1500

EDIT: Okey, I got 2.421Mh/s avg.

Yes seems to work stable, but I it only runs now ~ 2h.

I've had a lot of trouble configuring my 290X. It seems to be stable now (24 hours) getting 2.6Mh/s with a version of sgminer for darkcoin from badman74, now a week or two old - I'll probably work on the latest version today now that things seem stable. I have not yet found a good configuration for scrypt mining with cgminer on the 290X - that has been terrible so far.

Doing lots of tweaking, I think I've found a pattern. Whenever things get out of hand - intensity too high, for example - and the system (Win7 64 for me) gets unstable enough that it flashes a message that the video driver has become unstable and has recovered - then it does not really recover. Instead, the recovery seems to cap the memory clock rate at 150.

This means that all future test results are misleading. You can change various things, and the changes have an effect, but mysteriously you never again get high performance from your card. Eventually a hard boot removes the cap, perhaps causing all your tweaking to produce different results for a while, until the momentary crash and faux recovery kick in again.

The behavior seems to apply for all recent versions of AMD Catalyst drivers.

I found out this was happening by using a stand-alone utility freebie to watch the card's behavior - gpu-z from techpowerup. The AMD Catalyst control center display seemed to give unreliable results.

fwiw, here's what I'm using now in a bat file:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx DISPLAY 0
cd (appropriate directory)

sgminer.exe --kernel darkcoin -o poolstuff -u username -p password -I 18 --lookup-gap 2 --shaders 2816 --thread-concurrency 32765 -g 1 -w 512 --gpu-engine 1040 --gpu-memclock 1200 --auto-fan --temp-hysteresis 10
 
I wouldn't suggest you copy it too literally. The "shaders" setting (which may or may not matter at all) is for a 290X, not a 290. The temp-hysteresis is probably much higher than needed. Intensity was dialed back from 19 out of annoyance at instability. The memclock setting might be important - it is less than spec for the card, but seems to have helped with stability so that I never get the dreaded faux recovery message now. Maybe  

tl;dr Check your 290(X) GPU memory clock actual values during testing with something like gpu-z - see if it has become locked at 150, regardless of what value you might have asked for.

Hope this helps someone.

Edit: Update - after lots more drama with my 290X it's now stable again, even at memclock 1250. The drama included driver rollback and card re-install so I'm no longer sure whether the "locked memory clock" was a cause or just an artifact of other problems. Keep it in mind though if you get weird 290X behavior.

Try to increase --gpu-powertune to 50 and increase thread-concurrency value (try for example 25000).

Theses are your 290 settings?
Your 290 is stable at 2.5, even after an hour of mining?

Hi!

I'm only getting 1.24Mh/s on the Sapphire r9-280x, I guess it should be a little more, with my R9-290 I get ~2.5Mh/s.

Thats my current config:

--shaders 2048 -I 23 -g 2 --thread-concurrency 16374 --lookup-gap 2 -w 256  --auto-fan  --gpu-fan 80-100 --gpu-powertune 2   --gpu-engine 1100 --gpu-memclock 1250

any suggestions how to tweak this?

Myr results:
GPU HD6770 (core/mem 800/1100MHz)
CPU [email protected]

result as shown by sgminer: 3.6Mh/s (pools are showing something in kh/s :S)

Gpu load ~94%, Cpu load ~95%

command line used:

My config is with intensity 21, 1 thread, and memclock 1500

I'm in a much worse situation: my 290 does a maximum of 500K, while an old 7950 does almost 1700K.

I need some help with 290 cards.

I always started well with 2.4M hash, then after a few minutes, it starts decreasing slowly, all the way tl 2.1M.
It did that on all my 290, and just on my 290s: on my 280 I have some stable 2.1M from the beginning to the end.

I first suspected it was some sort of bios issue, but I got the same with a custom bios.
Any-one have a stable mining with a 290 that last a few hours above 2.4M?

Hi. I can't run.

what do you think?

mYR:
6850 get 7.7M
5750 get 5M
AND 270 ONLY 6.7m!
280x only 10m
 It is very strange for older GPU getting a higher speed~

got it from 2nd link thanks

Just download it from web or you could download earlier version of sgminer and take zlib.dll from there.

Im getting  zlib1.dll  error on windows

ahh ok was gonna say i didnt really see anything wrong either but i run windows so it works a little differently
