Hi guys,
I need your help. I bought a farm in Chinese on chips Avalon 3. In cgminer written that their hashrate about 800 GHash. The problem is that on the pool hashrate between 500 and 600 GHash.
Has anybody had a similar problem?

A little about the farm: it consists of 3 cards, and each card is detected cgminer as a separate device; each card is now working on the same worker.
I had the idea to distribute each card for different workers. I tried to set the parameters of the Cgminer to Load Balance and Balance but still only works Worker #1. Apparently I'm doing something wrong :(

Load balancing won't make any difference to your problem. What do stales and rejected look like?

Nope. Outside and inside everything looks okay. At least I don't see any defects.
And besides, in cgminer status is shown that hashrate 800.http://s7.postimg.org/j1uemfzsb/image.png (http://postimg.org/image/jelssmi1z/full/)

On one of the forums said that the Chinese could somehow wrong to flash chips. Because of this, they may not work correctly with each other. That's why I want to distribute them.

Look at your discarded shares, that's huge (and from the pool). You got your difficulty set appropriately, and is it the same on a different pool?

Initially I was on ghash.io and difficulty set to 512. Then I switched to bitcoin.cz (ex slush). There difficulty is not installed or is installed automatically. In both cases, the number of Discarded was about the same (proportionally).
This is really a lot? It may be worth it to switch to another application pool?

Try btcguild, its always a reliable benchmark. Nevermind about the stales, didn't know that label was DiffA there.

Is it the same after soft and hard restarts?

Tried it. It does not help.

I.e. you give me to move to a different pool (btcguild)?

Now I go to sleep. Thanks a lot for your answers. Tomorrow I will try your advice.
See you later

Same problem here. Balance and Load Balance do not work as expected.

I don't think it's a pool problem, because I tried several pools and still the same problem.
I guess it might be a cgminer problem.

I'm pretty sure that the problem is # Discarded in 2 times more than # Accepted (as noted dogie).      
You have the same ratio of Discarded/Accepted?

Thats actually fine, because accepted is at difficulty 500-1000 while discarded is difficulty 1 (so there is actually 250-500x more accepteds than discardeds). Maybe worth calling in ckolivas if you think its cgminer related

dogie, thanks for you response.  I'll do that.
