The 32bit operating system you are using is not capable of addressing 4gb's of RAM. You need a 64 bit o/s.

 

[kg4icg]

using 32 bit or 64 bit, in which i'm guessing 32 bit in which you take your system ram and subtract the memory in your video card and guess what, that's all 32 bit windows is going to show you. 32 bit win xppro, vista, and even win 7 only use a max of "and read this carefully" 4 gig of total system memory, which in fact includes the mem on a video card.

so if i use 64 bit version of Windows will it show me My 4Gb Of ram

 

[erocker]

Yes it will.

 

[newhariharan2008]

Yes it will.

Don't get XP x64. Vista64 is much more stable and faster.

 

[silkstone]

They're both good SF, but i'd also go with vista x64. Your system will handle vista very nicely

 

[Error 404]

so if i use 64 bit version of Windows will it show me My 4Gb Of ram

It wont just show you the 4 GB of RAM, it will use it fully! Although Vista 64 would be much better than XP 64 IMO.

This may convince you...

Running XP x64 here and all 6 GiB are registering:

XP x64 has only BSOD'd once in 4 years and that was when I pushed the memory clocks too far. No overclocks, good drivers, and it is 100% stable.

Yep, you hit the nail right on the head, dead center.

But, I would go with 64 Vista or at, least 64 bit xp, too.

4-Gigabyte Tuning

To enable 4GT, use the BCDEdit /set command to set the increaseuserva boot entry option to a value between 2048 (2 GB) and 3072 (3 GB).

Windows Server 2003 and earlier: To enable 4GT, add the /3GB switch to the Boot.ini file. The /3GB switch is supported on the following systems:

* Windows Server 2003
* Windows XP Professional
* Windows 2000 Datacenter Server
* Windows 2000 Advanced Server

The /3GB switch makes a full 3 GB of virtual address space available to applications and reduces the amount available to the system to 1 GB. On Windows Server 2003, the amount of address space available to applications can be adjusted by setting the /USERVA switch in Boot.ini to a value between 2048 and 3072, which increases the amount of address space available to the system. This can help maintain overall system performance when the application requires more than 2 GB but less than 3 GB of address space.http://msdn.microsoft.com/en-us/library/bb613473(VS.85).aspx

Just download windows 7 or use the free windows downloads that can be found on msdn.com

A pretty big improvement coming from an Opteron 180. I waited for Nehalem knowing it would be a major improvement from Core 2/Phenom. It has waltzed through everything I've thrown at it (mostly games and programming). The 920 is on par or better performing than my 2 x Xeon 5310 processors.

Another Trick that Does Speed up Overall Windows is Turning off the Paging file, I would only recommend that if you have more than 4 Gigs of Ram tho (if there is more tweaking to memory managment core). I did this on my laptop with 2 Gigs and sure enough the OS was as speedy as Win98SE on a Athlon XP, drawback was I ran out of Resources during 7Zip maximum Compression.
