I read some articles about "4g Decoding" on some motherboards and still not sure how this works with cypto mining.
 Some say this should be enabled when multiple gpu are installed?

    It's a legacy 32 bit address limitation related to how Windows and PC-based hardware set up access to the RAM and many peripherals.
     
     
    Some older BIOS won't access more than 4 GB of address space by default, this switch in such a BIOS changes that so they will access more address space - usually at a SMALL cost in memory access performance (and access to anything else like GPU "shared" memory that is memory-mapped).
     
    It basically tells the BIOS that ALL access to the address space needs to use 64-bit addressing instead of 32-bit addressing.
     

    Now that vorsholk has stopped his abuse, I'm returning to folding.
     I no longer MOO due to abuses by certain "whales" in the Gridcoin community - so I now work the Distributed.net project directly again.

    Thanks for you info. I just found this build they have @ Nicehash and they mention enabling 4g decoding for their 8 gpu rig.
