ed 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.

Also, what miner are you using? I'm using cgminer 3.7.2 with a bunch of r9 280x's, averaging about 1% reject rate.

Thanks for your help. I´m using "guiminer script alpha". All drivers are new, fresh system (win 7, 32 and win 8, 64). I´ve used this setting since 2 weeks without any problems <1% invalids to mine LTC at another pool. I tried different dif. - no change. I tried 11 worker and only 1 worker for all GPUs - no change. Hash rate is fine, but my miner tells me around 10 - 15% invalids. Pool tells me between 50 and 10% invalid. If the pool is changing the invalids are going to 50%.

Can you try cgminer 3.7.2? check out the litecoin hardware comparison site for tips on how to configure yours. https://litecoin.info/Mining_hardware_comparison

That's what I used to configure mine, and I get identical results to what's listed there.

Ok. Tried a lot this night. The Problem are the EU server. With EU server 10 - 15% and up to 70%(!!!) invalid shares. Same settings now with the US server (and I´m from Germany) only 1-2% invalid shares. Thats fine for me.

Admin, you should take a look at the EU server!!!

Thanks to all, who tried to help me. Wish I had tried US server first and not after hours of tuning my settings and system - what´s no fun with 4 rigs and 11 GPUs Wink
