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.
