It is free and open-source software, and is available in 32- and 64-bit variants. It is digitally signed, which makes it compatible with 64-bit versions of Microsoft Windows without having to be run in Test mode. The 64-bit version has no practical limit to the size of RAM disk that may be created.
The 2 GB limit refers to a physical memory barrier for a process running on a 32-bit operating system, which can only use a maximum of 2 GB of memory. [1] The problem mainly affects 32-bit versions of operating systems like Microsoft Windows and Linux, although some variants of the latter can overcome this barrier. [2]
Many 32-bit computers have 32 physical address bits and are thus limited to 4 GiB (2 32 words) of memory. [3] [4] x86 processors prior to the Pentium Pro have 32 or fewer physical address bits; however, most x86 processors since the Pentium Pro, which was first sold in 1995, have the Physical Address Extension (PAE) mechanism, [5]: 445 which allows addressing up to 64 GiB (2 36 words) of memory.
The term 64-bit also describes a generation of computers in which 64-bit processors are the norm. 64 bits is a word size that defines certain classes of computer architecture, buses, memory, and CPUs and, by extension, the software that runs on them. 64-bit CPUs have been used in supercomputers since the 1970s (Cray-1, 1975) and in reduced ...
Reverting to the latest driver available from the Intel website, i.e. v8.15.10.1930 [10] (initially released for Windows 7 64-bit) seems to reduce the occurrence. This computer has two DDR2 SODIMM slots and can be upgraded to 6 GB of RAM, with a set of 2 GB and 4 GB modules. Both 667 Mhz and 800 Mhz modules are supported (PC2-5300 or PC2-6400).
If you have a computer with a 32-bit setup, you can upgrade to the 64-bit version without acquiring a new license. The only caveat is that there is no in-place upgrade path to make the switch.
