Sadly, i cant get my 2x 6950 system to run at all on cgminer. I've tried numerous versions of cgminer from 2.5 to 3.5 and all of them crash except 2.7.7 in which it tells me this:
http://i85.photobucket.com/albums/k62/rusolinio/miner1.jpg
My config files contents are:
cgminer --scrypt -o stratum+tcp://global.wemineltc.com:3335 -u username -p pass -w 256 -g 1 -I 18
Looks right to me? The miner details are correct and confirmed by another system running cuda miner and 2x780's. Can anyone see whats wrong here? All the other versions of cgminer i have tried hang on startup for a few mins then crashes ala 'cgminer stopped working'.
I am currently using 13.10 catalyst drivers with SDK 2.7 (tried the latest 13.9 drivers and SDK 2.9 = no luck).
Does any kind soul have any idea where i could even begin to start to look for the issue? Brain is frazzled and i would seriously appreciate any help anyone at all may offer.
For now, i have to stick with the 2x780's and the almighty speed of 560kh/s they produce.

13.9 worked well for hashing. Win 7 Pro 64. 7970 Sapphire.
Anyone experiences hash rate halving with newer drivers?
Was playing with 13.10 beta and it's great for games, but makes my 7970 hash at 370kh/s with my known good settings (600kh/s).
My card sucks btw, I can't get it over 625kh/s...tried bios flashing, different driver versions, added system ram.
Any thoughts?
System specs:
Gigabyte 7970 Windforce OC rev 1.0
i7 3820
2x2gb ddr3
Corsair tx750 psu
Win 7 64 bit pro
Catalyst 12.8 (tried a bunch)
Stock gpu bios...tried sapphire, other giga models.

Thanks, I sold that card though...will try with an r9 290 or 290x next.
Waiting, I was going to order or FPGA if the energy efficient is better compare to R9 290X
Scrypt fpga? I'd rather get a gpu which can be repurposed and sold to gamers...or just use the thing to game

I've managed to get 750 on all of my 7970s (Gigabyte GHZ editions)
i have been getting temps around 75c, but then again, I put --temp-target 75 so it's working well from what I can tell.
Care to elaborate on your cgminer settings and your MHZ? i have been getting temps around 75c, but then again, I put --temp-target 75 so it's working well from what I can tell.

Anyone give me some advice about run LTC with MSI 7950 Twin Frozr 3GD5/OC (performance ,save power)
my config :

my hashrate about 610-625kh/s.Is this a good choice?
I use driver on MSI website :MSI Graphics Driver 9.002 amd_9002_v78_vga (Window 7 x64)

I think this is not too bad for the Card, at least not if I compare it with what others receive. But with some tweaking it should be a couple of kH/s more.
on a side note: in your config you can skip the shaders option, it is obsolete as long as you use the thread-concurrency option. And perhaps it is worht setting the auto-fan feature.
Rgds
thankyou .Now i set core/mem 1100/1250 and it runs about 630~640kh.

Ah yes, the WAF .... (WomanAcceptanceFactor)
Good that it works out for you, glad to read that. But I'm a bit curious about the temp of the 6870. I think 2700rpm is something like 30-40%. I can imagine you did chose the temp target to get the best solution in terms of noise. But perhaps there is something inside your rack to optimize airflow. Seems abit to high for me with intensity of 12.

loved it. 6870 xfx is one of those "boxed" cards with one small fan at the end. It gets a really hot! + the other card is right under the fan producing a bit hotter air to cool 6870 with. small amount of dust adds 2-3/4 degrees there. 48% fan - 2800 rpm (atleast on my fan+ sometimes it falls down to 2650/2700rpm on same %... old gpu) i was mining btc at 51% fan with 85c .. after cleaning the card and replacing the cooling paste i did 48% fan with 80c. once i hit 50% on 83c it means i have to clean the card 45% fan = 2600rpm on my gpu.

In general the result in termes of hashes should be more or less equal. But for LTC it is kH/s instead of MH/s for BTC. Not sure but I think I read something about factor 0.9xx
according to the config you use the same settings for different cards, this might lead to the HW errors. Set the parameters for each card helps perhaps. Also for the finetuning. If your computer is dedicated to mining you can raise the Intensity to 16 or even more. Shaders setting is obsolete as long you are also using the thread-concurrency setting.
Also the thread-concurrency can lead to HW errors if it is set too low. Some said the tc should be a multiplier of the shaders, some say it should be a multiplier of 64. good is what gives best hashrate.
RGDS
thank you very much. yes all you said is correct. found that info online and tried to apply it to my bat file. im using my pc everyday and need my first gpu to handle all my work without any lagg. after i found out how to apply different settings to my gpus HW were much more easy to get rid off. to find a good thread concurrency without HW i did 6144 - 64 - 64 - 64 untill i found a good spot.
This is how my bat file looks now :
color 02
cgminer --scrypt -o http://stratum.give-me-ltc.com:3334 -u xxxx -p xxxx --thread-concurrency 4352,5600 --auto-fan --temp-target 83,75 --auto-gpu --gpu-engine 800-900 -I 12,17 -g 1 -w 64 --temp-cutoff 91
With this i get :
6870 : 82c 2700rpm 246 khash 0 R 0 HW 2.3 shares per minute -i 12
6850 : 74c 2780rpm 259 khash 0 R 0 HW 2.5 shares per minute -i 17
i know i can press both cards a bit more etc but since i need some of the computing power and GF hates the fan noise this is the setting im okey with.

Hello . hoping that someone with 6870 gpus or some knowhow can help me out.
I just started mining LTC but im getting less share per minute then with BTC mining. im getting few HW on one of the cards. alot of both if i change thread concurrency
