hi,

My pc has a i3570 and a ati 9750 but i am getting only 3kh on it?

I'm trying to earn store up some litecoins

But I think cgminer is  using only the built in gpu, the one on the chip or motherboard, and is ignoring the dedicated card, because i get the same speed on my other pc with no dedicated gpu.

I've tried both of those and neither work

cgminer -o stratum+tcp://coinotron.com:3334 -u user -p password --scrypt

cgminer -o stratum+tcp://coinotron.com:3334 -u user -p password -I d,9 --scrypt


also i have downloaded and installed that

AMD-APP-SDK-v2.8-package,

still i can only get very low 3k hash , something is wrong i think cgminer is not able to see my dedicated card.

Can anyone tell me what has gone wrong.

Is there something other than cgminer that may work?

thanks

Is it defaulting to your onboard video card?

hi,

yes it is, i can see it just says gpu0  there is no mention of gpu1.   

Is there a way to force cgminer to find all gpu on the system?
thanks

Yes, it is defaulting to that.

Run cgminer -n (or cgminer --ndevs) to get your devices and their numbers.
Then, run what you were running, but with -d (device number 1),(device number 2)

If you happen to make any litecoins/bitcoins, mind donating? ;)

LTC: I don't have one, due to there not being an (good, not charging-half-your-money) online wallet for it. Just exchange LTC for BTC if you don't mind :D

hi,

thanks for trying to help,

and yes i will donate you my first 5 ltc if with your help i can ever get my pc to work with cgminer. I'm not sure even if i get my machine working how long it will take to get 5 ltc or how much bitcoin that will be. Sadly probably not a lot since btc is worth a lot more but much harder to obtain.

i tried creating a bat file with just

cgminer -n


but cgminer just popped up for a second and vanished, tried again same thing.

i think should have mentioned that i am on windows 7 64bit too.

hi,

thanks for letting me know. I have been here hours trying to figure it out.

So for now we can't use cgminer?  is it time to try a different mining application? If so which one would you recommend that works with the new drivers?

thanks

I deleted my previous post because everything seems ok now that I upgraded cgminer to 2.11.4. I assume my problem was an old cgminer with new AMD drivers. Maybe you have a similar problem.

no, i tried the lastest cgminer  and still the same thing :(

anyone have any ideas on this ? 

cgminer simply can not see my dedicated card it seems.

Ooh OK then, *challenge accepted* :)

Step 1. Open up Command Prompt and run cgminer -n. This should print out a list of devices and numbers. Copy-paste that into your post.
Step 2. Put into your batch file:
cgminer -o stratum+tcp://coinotron.com:3334 -u user -p password --scrypt -d (device 1),(device 2) (that is, what you had before but with the -d part)
replacing (device 1) and (device 2) with your device numbers.
If you can't find your device numbers, post the output of cgminer -n and then I can help you.

hi,

I opened up the cmd prompt and pasted in exactly

cgminer -n

it says cgiminer is not a recognised command.

Sorry i have no idea how to run cmd line things.


Do i have to somehow point it to the correct prog by telling it the directory


i also tried

start cgminer -n

it seemed to not like that either .

Can u really baby step that part to me.


also, this is even more strange...

i put my friends 7950 in my machine and now the cgminer is seeing 2 gpu

and both the 7950 according to gpz are running at 95% flat out.

also both gpu 0 and gpu 1 are scoring almost exactly the same hash

but both together are getting only slightly more than my laptop which has just intel graphics.

this is really weird, since i think cgminer was always using my first 7950 but hash rate is tiny. 

Im not sure what is happening.

You'd need to have cgminer in your PATH or cd into the directory cgminer.exe is. So type: cd c:\whatever\cgminer

hi,
great it worked  - here is the output

i think cgminer is seeing the 2x 7950 since when i run it both go up to max usage?

does that cmd prompt show anything that could be the issue?

sorry i meant to say , the cards are running at max but only generating 8khs, not that they are running at full speed and they are working at expected hash rates. Some other threads have said certain versions of cgminer do throttle hash rate for some unknown reason and have changed versions to older ones. However i have only tried the last 2 versions so i'm not sure about that.

this error

Failed to ADL_Adapter_ID_Get. Error -1

is that bad?

Failed to ADL_Adapter_ID_Get. Error -1 - probably not a problem.

So, have you tried running your batch file with -d 0,1 added? If you do that, you should get the results with both GPUs.
I'm not a mantainer/contributor to cgminer, so you'll need to ask the cgminer devs about the slow speed.
Send any donation BTC to the address below, thanks :)

Someone call for help, *headache* It looks driver related, but you'd think you couldnt get so far with bad drivers.
Have you tried just running AMD's driver cleanup utility (Works freaking great) and THEN installing new drivers?

I have a feeling its something like a bad SDK that cant control the 7xxx GCN architecture properly.

I DO NOT KNOW WHAT IS WRONG, I am just pitching ideas

hi,

well i put this exact command in the bat file

cgminer -o stratum+tcp://coinotron.com:3334 -u user -p password  -d 0 -d 1 --scrypt

still the same problem, 8kh for both combined. :(

seems something else is wrong, not sure what.

both cards are maxed out but only getting 8khz, maybe somehow its not using scrypt or something like that.

--scrypt is not a valid CGMiner option (I'm using 2.11.3)

Add the option --gpu-platform 1 and the option -g 2 (you can increase/decrease that number to change the number of threads/GPU)

so i should remove that from the bat file --scrypt ?? i was told on here to put in.  I thought i had to put that in or else with would do the 256hash thing for bitcoin?

Please can you post the exact line you suggest i put in the bat file.   

thanks

Well, it's not crashing, so put in this line:

cgminer -o stratum+tcp://coinotron.com:3334 -u user -p password  -d 0 -d 1 --scrypt --gpu-platform 1 -g 2

hey that actually did something :) thanks

speed went up to 500 each instead of 8, now  the cgminer box is full of  messages all saying same thing

rejected hash rate above target...

or other pools

share is above target.



something is probably still going wrong and the screen is all glitching. Perhaps i need to turn down intensity. I put -I 6  in the line but still all the reject  hash rate above target... infact -I 6  didnt seem any different from -I 10.

it's nearly 10am and ive been trying this for 24hours lol. Perhaps tomorrow i will work out how to mine a coin. I think i have 0.006 ltc atm but i will spend tomorrow trying to find out why this error is happening now.

thanks to all that tried to help even if i never get to mine a coin i will buy some and support this because i really like the idea of it. I would have bought some by now but even that seems hard. I tried to get some but nobody takes paypal anywhere.

You should have really stated WHAT you are trying to mine.
Since its Litecoins, You NEED the --scrypt
Gosh have you even tried mining a Bitcoin before trying litecoins? Its like you dont understand that Scrypt mining is roughly 1000x times slower than SHA-256 (bitcoin) Mining

the "screen is all glitching" Is probobly from a Bad Overclock, or shotty drivers. Mining does not cause graphic errors unless you're on shitty drivers.
Intensity is "how hard" you want your card to try and hash.
Some cards will show no differance in hash rate when changing from 5,6,7,8,9, Its all the same, but 1,2,3,4,10,11,12,13 give differant speeds (My 7950)
Intensity 6=550Mh/s (using my comp)
Intensity 2=480Mh/s (gaming)
Intensity 13=560Mh/s (Cold Nights)
Intensity 10=555Mh/s  (overnight)
