The 3.6 GB Memory problem with 32 Bit

0	Why has there never been a patch to allow 32-bit processors and motherboards to run more than 3.6 GB of memory? Is this simply a thing to get you to buy the 64-bit? 32-bit 64-bit memory asked Sep 21 '10 at 12:56 shivabeach 1●1●1●1 edited Sep 21 '10 at 12:58 Danish (suspended)

you cannot patch the hardware but if it supports it windows allows you to turn on Physical Address Extension, allowing you to use you computer is 36bit if i recall correctly

Thank you. I hadnt thought of that. I thought the 32 bit requirement was in the Operating software

It's not a software thing, it's a hardware limitation in the processor itself.

The range of integer values that can be stored in 32 bits is 0 through 4,294,967,295 or −2,147,483,648 through 2,147,483,647 using two's complement encoding. Hence, a processor with 32-bit memory addresses can directly access 4 GB of byte-addressable memory. (Source)
