Hi,
As per the title, I now successfully have 6x 8Gb cards running, and have just found a couple of old 2GB cards in my loft....
People say you cant really mine with 2GB cards, but just wondered how it worked if they were mixed with bigger cards?
So can I put them in my rig and presumably it will run fine plus a few more MH/s maybe?
Or does each card work independently and the 2Gb will simply not do much?
They are both GeForce Nvidia 2Gb 520's I think?
GB is not a metric of performance, its just the memory size available to the GPU. When you say you have 6 x 8GB cards, it means nothing because its irrelevant information. Tell us the make and brand of the card coz those matter, the GPU chip on it matters, the memory capacity hardly matters - the only impact that can have on mining is like you mentioned above, under 2gb cards cant mine Eth.
That being said, Nvidia 520's are waaaaay too ancient to be able to mine anything even remotely profitable.
