Hi, I´m new at the pool. I´m running 11 GPUs at around 6500 MHash.

My problem is, that I have a lot of invalid shares. Mostly around 50%!!! Is it normal for DOGE? If yes, DOGE isn´t a good coin to mine, because the profitability is not 50, it´s 50% of 50 = 25.

At the moment I´ve:

Valid Round Shares = 38336
Invalid Round Shares = 12096
Your Efficiency = 76.02%

Normally when I mine LTC, I´ve max. 1% of invalid.

What can I do?

Edit: I´ve 11 worker at the pool. 1 for each GPU. Is it better to run all GPUs on only 1 worker?

Something is seriously awry. I'd run as much GPUs as you can on one worker, per instance of your software miner. For example, I have 3 rigs, so I have 3 workers, each has one instance of cgminer. My invalids are < 1%. Also make sure your difficulty is scaled accordingly, the recommendations are on the help page.

Thx. I took the difficulty from the help content. All my cards are set on 64 at the pool and inside my miner. Could it be, because of my many single workers? Could it be a disadvantage to set it to 32 or 16? I´ve x280 cards with around 700 MHash.

I still need some help, please. I set all my GPUs on one worker. It doesn´t help. I still have a lot of invalids. I´m mining on the EU pool. Are there some problems with the server?

At the moment:

10 Minute Hash Rate 5907 Kh/s
Valid Round Shares 13056
Invalid Round Shares 9024
Your Efficiency 59.13%

Edit: I even tried dif. of 16 and 32. It´s worse. Between 64 and 256 is no difference.
