Can we access all 4GB RAM for Windows 2003 ?

[Guest Meinolf Weber]

Hello Patrick,

 

Thats by design of 32bit software. If you like to see all 4GB RAM install

the 64bit version. And 2003 Standard 32bit can only use 4GB RAM in total.

 

Best regards

Can we access all 4GB RAM for Windows 2003 ?

 

Hi,

 

We just set up a Windows 2003 Server (32 bit) with 4GB RAM. However, we are

only able to see 3.4GB memory.

 

Someone has suggested that we can change the BOOT.INI to add AWE and will be

able to see all RAM available.

 

We would like to know if we do add AWE and we are able to see all 4GB RAM,

does it mean that we can use all 4GB ? If just 3.4GB can be used, what is

the point in adding AWE ?

 

Thanks

Dear Meinolf,

 

Thanks for your prompt reply.

 

From your reply, my understanding is that we can use (not view only) all 4GB

RAM if AWE is enabled ?

 

Thanks

Meinolf already replied on this issue re 32-bit OS. AWE won't help you

but you can try and use the /3GB switch and eek out a little bit more

for your apps. It does borrow away from kernel paging but I've not had

any issue with it starving for memory in the 2+ years I've implemented

it. Nope, 3.4 is not too bad for 4GB of available RAM from your

server. We're right around 3.65 ourselves. If you're on SP2 and fully

patched, drivers up to date and such, /3GB will help more than /AWE.

Good luck.

If I remember correctly the switch you need to use for 4gb is /PAE

 

Hope this helps

Page Address Extension is to see more than 4GB RAM in Server

Enterprise or higher.

You don't "enable AWE" in boot.ini. AWE is an API - applications have to be

specifically coded to use it.

 

The issue with not being able to use all of 4 GB of RAM is a hardware design

issue. See http://support.microsoft.com/kb/929605.

It is perfectly useless to know the right answer to the wrong question.

Dear Bruce,

 

Thank you for your advice. I have searched the web and found that we can

only use the /3G switch in boot.ini & there is no AWE switch.

 

Regards,

Patrick
