I know that 64 supports 4 RAM and more and 32 bit doesnt. RAM is irelevant for my performance couse i have 2GB.

I have 2 GB of RAM. Im using now W7 7000 32bit version. I want to download 7068 version and im willing to try 64 bit version.

My question is will i have any benefit or performance gain by running 64bit version with 2GB of RAM.

I know that by running 32bit game on 64bit system will have no gain in prefrormance comparing to 32bit system.

But. For example if i run games like Crysis64 witch support 64 bit will it run better.

Also I heard that there is advantage in multitasking. Will i have any advantage while just working in Windows 7??

You probably won't have any performance gains. Keep in mind that 64 bit OS's and software do consume a bit more memory, too.

For you, install it if you want to try it, but it won't help you, really.

However, if you think you might upgrade to 4GB RAM later, then install the 64 bit version. You cannot upgrade from 32 bit to 64 bit, so you should install it from the get-go if you think you might get the RAM later.

Just buy more ram and you don't want to worry if it's worth using 64bit OS.

I have 2 GB RAM (build 7068) and to be honest I don't see any performance improvements, only that it uses more ram than 32bit. When RC is out I'll get the 32 bit version.
Anyway the bild is very stable, I didn't encounter any problems with It.

i dont see the point of goin 32bit..2gigs is really low nowadays..will be even worse upon W7's release
and its 'future proof' to go 64bit, in case you do upgrade cause ram is dog cheap

i really wish they had dropped 32bit completely, most processors are 64bit, if you have a 32bit processor then your system must be god awful slow and should probably stick to xp

A large piece of the application market is 32bit only. Windows can't just go 64bit exclusively all of a sudden.

Even if Windows 64bit handles both modes simultaneously... I don't think it would be wise to keep out older 32 bit processors from running Windows 7.

Yes, you should see performance improvements when using a 64-bit version, especially in tasks which are very CPU intensive. The 64-bit versions use a different (better) function calling convention by default (everything is essentially fastcall instead of cdecl or stdcall) which takes advantage of all the extra registers present on a 64-bit CPU when passing arguments to functions, meaning a lot more function parameters get stored in registers (fast!) instead of getting pushed to the stack (not quite as fast).

You also have the advantage of all these extra registers being available when actually executing code, which a compiler targeting 64-bit will happily make use of.

on my 7000 32 bit i dont have any performance problem with my 3.16Ghz Core2Duo and 2GB of RAM. I play all new games on maximum settings with 1440x900 resolution. System is working ultra fast.


First. No one answered me if i will have advantage by running 64bit application like Crysis64 on 64 bit system.

Second. Is there a big difference between 7000 and 7068 version. Did they fixed some important stuff or its small change.

No, I would not do it. You may not notice it now but when more and more apps are x64 you might. I would run it with at least 4GB.

Faster Loading Times, that is about it for Crysisx64 or Hl2x64. :/

There is no performance increase with only 2 gigs of ram but there is a security increase.

OK. just two more questions left unanswerd to make my decition.


1.Is there a big difference between 7000 and 7068 version. Did they fixed some important stuff or its small change?

2.How many MB of Physical memory Windows 7 64bit use after boot on idle. For example Windows 7 32bit use about 530MB of 2GB (26%).

I think you should just go ahead and install the 64-bit version. That way you can see for yourself what it's like and how it runs on your system. You're going to be reinstalling in a few months anyway, so there's nothing to lose. It's true that the 64-bit version uses more RAM, but it's not a lot, and the marginal (for most things) performance improvement might make up for it. You'll have to be the judge of that.

That's not a very good measure, since it depends on many factors. It'll be in the same area. On this 2GB machine, it's 500MB. I wouldn't pay too much attention to the fact that 64-bit (and the 32-bit emulator) uses slightly more RAM, chances are you won't notice it.

A P3 1ghz with 512mb of PC133 ram runs W7 minus Aero just as well as it runs XP, which is amazing because Vista just tanks on CPU utilization.
