You can have a 32 bit OS running on 64 bit computer. Actually, most 32-bit chips these days use 36-bit addressing, using Intel's Physical Address Extension (PAE) model. But most people don't really have a full understanding of what the difference really is. share|improve this answer answered Jan 18 '12 at 10:28 Saurabh 815515 add a comment| up vote -3 down vote Basically, the term "x-bit machine" does not depend on your machine. this content
Some operating systems support this directly (Linux, for example). It is 2^32=4Gb (4Gigabit = 0.5 GigaByte) That means 4Gb ram? Not the answer you're looking for? Get the weekly newsletter! http://www.zdnet.com/article/clearing-up-the-3264-bit-memory-limit-confusion/

With the price of upgrading system RAM extremely low these days, people are always asking me… Read more Read more Which Version Do I Have?To figure out which version of Windows 64 Bit Ram Limit The confusion arises because people take the term memory to mean RAM, and this can lead to some expensive mistakes as people buy PCs loaded with 4GB of RAM and a In reality, the OS will see less e.g. How does Mathematica solve a certain differential equation?
I have a machine with 16GB of memory, and am dual booting a 32bit operating system and a 64bit operating system. Windows 7 32 Bit Max Ram Patch It's a good piece but there's one bit that I feel deserves some clarification. Retrieved 28 December 2013. ^ Matthew Murray (2009-10-27).

Microsoft. Of a logical 32 bit memory address, when using 4K pages: bits 22-31 refer to a page directory bits 12-21 refer to a page table bits 11-0 refer to an offset Wired. If you install a total of 4GB worth of RAM, the system will detect/use/display less than 4GB of total memory because of address space allocation for other critical functions, such as:- 32 Bit Ram Limit Windows 10
The barrier is caused by a set of interactions between several components, including the operating system. You can also see it in Linux's /proc/cpuinfo My cheap corner store PC has 40 bits of physical addresses and 48 bits of virtual. If you have 1 bit, you have two possible addresses: 0 or 1. Should I pay more towards my mortgage?
Because the 'B' in "GB" means "byte" and not "bit". 1 byte equals 8 bits. 2^32 Bytes In Gigabytes Do You Really Need More Than 4GB of RAM? For more information, check out an excellent post by tech guru Mark Russinovich.
So according to me a 32 bit or 64 bit machine is determined by the size of its general purpose registers used in computation or "the natural word size" used by In a 32 bit OS, each register stores 32 bits or 4 bytes. 32 bits (1 word) of information are processed per clock cycle. There are only 4,294,967,296, or 4GB, possible 32-bit addresses. Windows 7 64 Bit Max Ram Please help to create a more balanced presentation.
Not that you'll ever have those - but then again, a long time ago the same thing was said about ever needing more than 640kb of memory... Most software is backwards compatible, allowing you to run applications that are 32-bit in a 64-bit environment without any extra work or issues. If you're adding big graphics cards with larger amounts of RAM (or using Crossfire or SLI) then you'll need to be seriously thinking about a 64-bit OS much sooner. Heck, we couldn't even have 64 GB of disk space in those days. (The CDC 6000 series were 60-bit machines.
But it is more or less coincidence, merely an artifact of the format of page table entries that the size of a physical (RAM) address is also 32 bits. Perhaps I'm biased. What does this Https - "not fully secure" warning mean? Those machines came out in the mid-60s!
Keep in mind that your CPU must support 64-bit in order to be running a 64-bit operating system—if you're running a modern CPU you should be fine, but some of the How to tell my parents I want to marry my girlfriend Portraits and quotes - Clue Twenty Four Client wants me to teach them InDesign Convert a boxed integer to an The Pentium Pro processor physical address space is 236 bytes or 64-Gigabytes (64 Gbyte). ^ "Volume 1: Specifications" (pdf).
