I have read many posts about maximum RAM with 32 and 64 machine systems/machine and still not clear on the answer. It is not clear if systems mean hardware or windows itself. Soooo...
Can i use more than 4 gig of RAM on a 64 bit architecture computer that is running 32 bit Windows 10 ?
No. For regular workstations, if you have a 32-bit Operating System, you are limited to 3 GB of memory or a bit more. Most workstations cannot readily manage PAE Extensions to use a more memory in a 32-bit OS (Servers more often will have PAE extensions), so just upgrade to a 64-bit OS to solve your issue. That works great.
