Guest huff-n-puff Posted November 9, 2007 Posted November 9, 2007 Hi I have just upgraded my server from 2GB to 4GB of RAM. It has Windows 2003 Server Enterprise 32Bit AMD Athlon64 3000+ CPU. Windows will only recognise 3.25 GB of the 4GB RAM. I have tried combinations of the /PAE or /3GB and /USERVA switches in the boot.ini file with no luck. Has anyone an idea of how to get Windows to see the full RAM? Thanks
Guest David Frasca Posted November 9, 2007 Posted November 9, 2007 Re: Server will not see all 4GB of RAM We have a similar issue with our Dell laptops. Dell said that the additional memory is being used for Video and other things, and assured us that the memory was being used. Not sure I believe it though.... Maybe it's a motherboard limitation on available addresses?

Guest John John Posted November 9, 2007 Posted November 9, 2007 Re: Server will not see all 4GB of RAM Unless you are using Server 2003 Enterprise or better, or a 64-Bit Windows version, you will not be able to see and use all 4GB of RAM. Practically all new hardware can properly make use of 4GB of RAM, the limitation is not on the hardware side, it is on 32-bit operating systems that cannot make full use of PAE. If you are using a 32-bit operating system the person at Dell did not correctly answer your questions... or you misunderstood what they told you ;-) John David Frasca wrote: > We have a similar issue with our Dell laptops.

Guest huff-n-puff Posted November 9, 2007 Posted November 9, 2007 Re: Server will not see all 4GB of RAM Hi Sorry, you seem to be answering the wrong question, about a Dell laptop, which isnt what I asked. Have you any idea on the original question posted a short while ago?

Guest John John Posted November 10, 2007 Posted November 10, 2007 Re: Server will not see all 4GB of RAM I didn't try to answer your question, I added to David's post, not to yours. And I made a mistake in my post, it should have read: "Unless you are using Server 2003 or better, or a 64-Bit Windows version, you will not be able to see and use all 4GB of RAM." As for your server I don't know why you aren't seeing all the installed RAM, Server 2003 Enterprise should be able to see and use all of it, it supports up to 64 GB of RAM, and the AMD Athlon 64 should be able to use all of it. Perhaps it's a motherboard issue, I don't know. Contact your hardware vendor and ask them.
