Mining with a 295x2 @ 1030 Core and 1300 Mem. However, as long as I use both GPUs, the hashrate is far too high (>2000 h/s) and I receive "code":-1,"message":"Low difficulty share" errors. I have tried different drivers, set virtual memmory size to 20Gb and played around with basically all the settings you provide in the readme. Nothing seems to help.

The only way I can use the card for mining is by using the -di 1 option. (When using -di 0, I get the same errors as with both GPUs)

My system:
Intel Core i7 2600k
Sapphire 295x2 OC @ Stock
Ati Catalyst 15.4 beta. (I have also tried 14.12 which did not help either)
850w Platimax. --> Plenty of power available. Its not that either.
Using Claymore GPU Miner v 9.3.

Apart from the errors while mining, the system is running rockstable.

Does anybody have an idea how to solve this problem?
