    I have Gigabyte RX 560 2 GB (1024 SP). GPU-z shows 128 GB/s but this program gives me that strange results. I can't even reach 110 GB/s and 4 last chunks are dozens times slower!

    Does this means that I have only 1536 MB vRAM :confused:?

    What should I do? I'm feeling like GTX 970 owners now.
