64bit on 32bit computer

[chocowalnut4]

hello,

i put a 64 bit windows 7 operating system on a 32 bit computer that ran windows vista previously. what is the worst that could happen with this?

If it installed successfully, then the CPU is 64-bit, in other words, it's fine.

Exactly what hardware does this computer have? Just about every x86 CPU made in the last 8-9 years is 64-bit.

i'm not sure but it is a gateway laptop t-series. the maximum color option is 32 bit though and the other is 16 bit

Color depth has nothing to do with processor architecture. Looks like the Gateway T series used Turion 64 X2 era CPU's. Well after they stopped producing 32-bit CPU's.

so everything is fine with my computer then?

No. You need a 128-bit OS (64x2)





yes, it's fine

Yep. CPU manufacturers were far ahead of the curve on the 64-bit migration. Of course that was sort of necessary before Windows migrated anyway.

Lol, I know your joking... but your gonna confuse him.

If you had a genuine 32bit computer, you would NOT be able run the 64bit code. Most modern computers are 64bit, BUT have 32bit software installed and this leads people to think they are 32bit instead.

All the Quad cores, i3, i5, i7 and new laptops are all 64bit. This includes the Mac as well

Something tells me we will never see consumer level 128-bit computers giving the nearly infinite amount of RAM that 64-bit can recognize. lol. I about choked when I diddied up that stats to see the deference between 32-bit and 64-bit. lol.

Being able to easily access memory in a small number of CPU instructions is one motivation for changes the length of CPU instructions, but it's not impossible to access more than 4 GB of memory on a 32 bit processor.

When processors move to 128 bits, the motivations will not be related to keeping the memory addressing fast and simple. There are other benefits to having longer CPU instructions, because accessing memory by address isn't the only operation CPU's do. They also operate on data. If you increase the instruction size to 128 bits, you can operate on larger numbers (or more precise numbers) in a small number of steps.

Currently, working with data of any type that is more than 64 bits takes many more operations than operating on data that is 64 bits or less on a 64 bit computer. It's not impossible either way, it just takes more steps.

This means that big integers, or extremely accurate floating point numbers (like quad precision floating point), are much slower to work with than 64-bit data types or smaller (because those 64 bit data types can more or less be handled in a single step on a 64 bit cpu).

Redesigning CPUs to handle data in chunks of 128 bits could provide performance benefits to those applications. That will happen when the market demands it.

Hope that helps.

Never say never when addressing (haha get it?) the computing market, you might generate your very own '640k' joke.
