    This guy has used PCIE-M.2 cards to split the 16 PCIE lanes in a GPU slot into 4x4 lanes of M2 and then used M2 to PCIE converters to connect 4 NVidia GPU to a 4 way M2 card. Under Linux there is no noticeable impact from using 4x PCIE over 16 but this way instead of being limited by the GPU slots, he "bifurcates" the PCIE lanes to get 6 GPU each with 4 PCIE lanes!

    Insane.

    Nowdays you could get nearly 10m PPD with just 3 cards.

    3080 Ti what if it has 8000 + CUDA cores?!

    What's the power draw for your two 2080ti for that 6m per day?

    I've got 5x1070s, a TitanX, a 970 and a 3600 contributing to my 6m and I suspect yours is a fair bit more power efficient...

    The TitanX is particularly inefficient pulling 274W at 1415MHz for at best 1.2m

    I haven't measured it really, I think its about 225W for one

    Yes, on the Windows machine I run it at 80% power with a +100 overclock, so it runs just shy of 200W on average.

    My machine in spec can peak at 510W from the wall
