Does anyone know or have experience with amd w7100 firepro cards or something similar? I'm having an issue where I'm getting about half my total speed or less than what's being reported for the card in the miner.
I have x4 running on nicehash and each one does almost 42mh, total speed in stats is around 167-170 but accepted speed is in the range of 50-80. Any ideas as to what is the cause of this? There's less than 1% rejected shares as well.
