OS not seeing all memory

Experts,


I have a HP DL380 G5 which has 8 gigs of ram installed.

I originally bought the server with 4 gigs, the OS was reading 3.25 gigs of ram in this config. I installed another 4 gigs so we can have a total of 8 gigs. The Bios and system management page see's all 8 gigs.

I installed the /pae switch to the Boot.ini. I am running Windows server 2003 R2 SP2.

The OS is only showing 4gb of ram, before i added the /pae switch it was 3.25gb.

How can i get the server to see the other 4 gigs?


What do you think i should do in order to see the rest?

If you use 32 bits OS, then that is all you can see. If you want use all of them, then install 64 bits.

He is using PAE to try and overcome this limit.

Here is a decent Wiki link for you and one from MSDN so you can check the way you have it set up.

Punky is right. The 32bit architecture is limited to only seeing 4 gig. You will need to go to 64bit os for Windows or your OS to utilize all your memory.

is this a safe way?

From what i understand now, it is not supposed to be supported in 32bit OS's. I wouldnt want to force it onto it, it may cause more issues.....

thanks for all the help guys.

Crucio666, that is right decision. The same questions like this posted in EE and other sites many many times, and there were suggestions to trick or hack but never be real. In fact, such hacking that is not sure was true, and it will not allowed to post in EE board, that is violating the rule and it is illegal.

Thanks for accept the answer.
Regards.
