64Bit OS on 32Bit Architecture... Whhaaaa

[litewarez]

At work today i learnt something new, and have not got an answer for it as if yet, but I think i know what i could be down to.

I have a computer 2GB, 32Bit duel core, and I asked my Line Manager if I Can set up and bench a 64Bit processor for a Share point project im doing.

As share point is only available for 64bit systems I needed a 64Bit computer to install the OS and Software, but my manager (Who is extremely cleaver) said to be, you see that 32Bit Mail server we just pulled out, I was like yeaaa, he said install it on that, i said you don't understand i need to install Windows Server 2008 R2 64Bit & Share Point 64Bit.

he said, it will work, true me.. so i started installing the OS and Whollla, 64bit OS running on a 32bit processor, i was confused, i thought this was not possible, so i started thinking how it could work?

I came up with because its Duel Core i thought they was acting as 32Bit + 32Bit, but I didn't think that was possible, and then I realised the board had written on it virtualization so done some research and found out it was a possibility.

Does anyone know exactly why this is possible, and if your unsure, well you know something new

i would like to know that too

I am sure its to do with CPU Virtualization that 32-bit can project a 64-bit system. It does not have the speed of a 64-bit but it does have the architecture. I think lol

[litewarez]

isn't Virtualization on the board though, not the Processor ?

It may be both mate I'm not 100% will have to ask my I.T Teacher

[litewarez]

Get back to me if no one else has a better prospective on it.

lite got his answer Pretty amazing

If the 32 bit OS sees dual core 64 processors as twin 32 bit processors, the benefit would not be in speed but stamina. Your system should be able to handle more tasks without any slow downs or impact on other operating software. I'd suggest you try playing music, running a video in media player and playing a FPS game to see if the system can handle it.

I base this on the fact that a friend of mine owned a dual processor MB back in the day with two Intel chips on it and was able to do a hell of a lot of multitasking that would have slowed other systems down.

I suspect the same could be true with dual core 64 bit processors running on a 32 bit

Im sure you can run x64 or x86 with any system that has more than one CPU core

Does that mean 4 cores is 128bit?

Mis understood the question at first.

I remember running xp 64 bit on a shit celeron processor i had. it was a 1.8 Single Core.
or maybe it was a Pentium 4 2.66Ghz. single core again.

whats the big mystery?
