Hi,
i really read my eyes out and try since a few days everything i find, but its just frustrating.
I have a SAPPHIRE Radeon HD 7970 3GB (11197-11-40G) and i cant get close to 600kh/s more like 400-500 kh/s
I tried Sabayon Linux 11 Driver 13.3 beta, 13.4 and SDK 2.8, 2.7 xubuntu 12.04 Driver driver 13.4 from the AMD page and the included drivers in xubuntu, sdk 2.6, 2.7, 2.8
XY variations of starting commands for cgminer 3.0.1 and 3.1.0 like --shaders 2048 --intensity 13 --worksize 256 --thread-concurrency 8192 -g 2 --shaders 2048 --intensity 13 --worksize 256 --thread-concurrency 8192 --intensity 13 --worksize 256 --thread-concurrency 8192 --intensity 13 --worksize 256 --thread-concurrency 22272 --intensity 13 --worksize 256 --thread-concurrency 22272 -g 2 --intensity 13 --worksize 256 --thread-concurrency XYZY --intensity 13 --worksize 256 --thread-concurrency 8192 --verbose -g 2 and i don't know how many more variations.
changing engine clock and/or memory clock has only one result, at some point the whole system crashes but it doesn't increase anything. memory clock crashes at 1600, 1575 runs mostly but has no effect engine clock crashes at 1100, but also ratio 0.57-0.6 or less or more has no effect at all. i have 6gb Kingston Hyper X, Intel(R) Core(TM) i7 CPU 950 @ 3.07GHz on a Gigabyte GA-X58a UD7 i use the system also as desktop, but since i try to get this running i have not much load on the pc who has an idea what i am doing wrong?
cheers

if you specify thread concurrency you don't need to specify shaders (its ignored).
This is what I use for a 6950 + 5770 system and I can get 600-700Khash/sec.
--intensity 20 --thread-concurrency 8192,3200 --gpu-threads 2 --worksize 256 --vectors 1 --temp-target 75 --auto-fan -s 3 --gpu-powertune 20

do you have the latest ATI drivers 13.4 ? if yes, than I think the driver is causing this problem, I had a similar problem yesterday and even when I deleted the drivers and went back to 12.8 cgminer did start but didn't post anything . I was struggling for hours, than a fresh windows install with only catalyst 12.8 (do not install the chipset drivers if your chipset is AMD as well) solved the problem, another member contacted me about the same problem I told him to do the same, he didn't reply , so I assume that this worked for him as well . - try it and post here if this helped you so other members will know about it.

Hi
For some reason my forth card in cgminer is always slower than rest of the punch ? 3 x 7950 mine at 620-630khash and the forth one is always at 580-590khash. Same problem on all of my 3 rigs and does not seem to be card specific as I have tried to swap them around and the result is still the same. Thought of trying to run a separate instance of cgminer for the fourth card but cant get --device|-d option to work in the scrypt . Cgminer 2.11 just starts up still running all four cards and cgminer 3.10 says "--device" is a unknown command and closes right away. Can someone please point out what am I doing wrong ?

either you have your screen plugged to that card or you just have to raise the power limit to +15%

either you have your screen plugged to that card or you just have to raise the power limit to +15% Raising the powerlimit does not help. The slow card is never the one connected to the monitor Can anyone see whats wrong in the srypt ? setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 cgminer.exe --scrypt -o stratum+tcp://stratum.give-me-ltc.com:3333 -u user -p x -o pooledbits.com -u user1 -p x --device|-d 0 --gpu-engine 1085 --gpu-memclock 1600 --gpu-powertune 20 --gpu-vddc 1.125 --worksize 256 -g1 -I 20 --lookup-gap 2 --shaders 1792 --thread-concurrency 21712 I want to run just one card out of four but the device -d 0 option doesnt seem to work..

No matter what I try I can't achieve over 140kh/s on my 5770 on linux. Any help? I've tried many concurrencys.
Linux Mint 14 Catalyst 13.4 6850 and 5770
I thought that maybe it was my SDK version, since my 6850 is fine but my 5770 isn't. Any version recommended?

Have you taken a look at this? And tried the settings for the 5770's listed? https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparisonAlso, I use CCC 13.5 Beta 2, with my 5850's, which I think is basically the same as the 13.4 driver, but the 13.5 beta 2 works flawlessly with the supplied sdk. Most likely a setting rather your sdk, maybe?

Here are the default values guiminer scrypt gives for a 5770 on Windows. Should perform almost the same in Linux imo? thread concurrency: 3200 worksize: 256 intensity: 18 That gets me 200 khash/s. With intensity 11 I get 153kH, good for desktop use.

I did look there. There are only 2 5770 recordings, and one is for Reaper. The other one I already tried, same result. Here is my settings for my 5770: --thread-concurrency 4000 --gpu-engine 850 --gpu-memclock 1200 --intensity 15 --worksize 256 -g 1
I also tried concurrency 3200, 4000, 4800, and 7680. They don't change more then 1kh/s. Worksize 128 and 64 lower it by about 5kh/s GPU_MAX_ALLOC_PERCENT changes nothing as well. Here are the default values guiminer scrypt gives for a 5770 on Windows. Should perform almost the same in Linux imo? thread concurrency: 3200 worksize: 256 intensity: 18 That gets me 200 khash/s. With intensity 11 I get 153kH, good for desktop use.
I'm using my exact same windows settings. I'd pull 200kh/s with my settings mentioned above on windows. I only pull 140kh/s on linux.

Maybe someone will find this useful: I'm using 4x 7970 cards, all on x1 > x16 extenders. Was getting max 690KH/s per card, but with old MB, CPU and only 2 of those card I was getting ~730Kh/s. I've changed priority of cgminer.exe process in Task Manager from Normal to High, and voila ~730 again per card So just make .bat with start "cgminer" \high in front and it will run it in high priority all the time.

That's weird, does cgminer.exe use any cpu processing power for the 7970's?

So that was my hint for CPU related issue. Don't know if I'm the only one noticing this, but it would be nice if someone else could confirm/deny this.

197Kh protocol litecoin
worksize 256 aggression 17 threads_per_gpu 1 sharethreads 18 lookup_gap 2 gpu_thread_concurrency 3700
1.013v, 600Mhz/825Mhz Cooling on mine isnt great so I run it slower and cooler. Reaper on win7 64 btw.

Im having some issues trying to get cgminer working with my 7950. I've figured out how to set up a conf file for whatever Im mining, and to launch the miner and get it hashing properly. My problems stem from not being able to use settings other 7950 users say work fine for them, and only topping out at 300 kh/s when I avg over 500 using the guiminer for scrypt.
What typically happens is I get a error saying I must lower either thread concurrency or lg when I enter the settings other 7950 users post, and when I can get it to work by lowering those settings the max I get out is around 300. Is there a reason my cgminer is thinking my card can't handle the settings it should be able to handle?
Thanks
