Am I missing something here? I know the dag file increased which makes 4gb cards useless but my laptop gpu has 5991MB of vram and I'm still only able to hash around 15.5 Mh/s this card is suppose to reach 28-30 Mh/s. Does nvidia require a bios update like AMD that I am not aware of?
According to whattomine and some other site this card should be around 28-30 Mh/s.
I can't find any info on this card about anyone having bad hashrates so I'm not sure what to do at this point. I have been mining CFX Octopus since it's getting good hash rates but i'd much rather be mining ether!
I'm hashing CFX Octopus at 27 Mh/s! I know it's a different algorithm but still. I'm confused.

Do a quick test with hiveos (from usb), it is well known that some cards are affected by performance loss due to progressive size of the ethereum dag file (Windows only).
