PowerEdge 800 - 4GB RAM not available??

Hi all!
 
I have installed 4x1GB Kingston RAM. In the bios i see the 4096MB Ram, but in Windows SBS 2003 i only have 3396 MB Ram available. With the change in the boot.ine with /PAE it makes no change. How can i bring all of the RAM to work? Must i make a Bios-Update? Or must i make changes in the bios? Have someone installed a PowerEdge 800 with 4GB Ram?

What this boils down to is that with the PCI-E in this server you will never see more than 3.5GB - the rest is used by the PCI bus.  If you have MORE than 4GB and an OS that supports it (x64 or Enterprise) then you can use the /PAE to mask around this *lost* memory.

If there is a bios upgrade available that will remap the upper memory, then you'd be able to see all 4GB of the ram if you use the /PAE switch. Else, your stuck with only getting to have 3.5GB available as long as you're running only a 32-bit non-Enterprise version of the Windows 2003 server o/s.

I ran into this problem on 9 brand new HP Proliant ML370G4 servers I bought a year ago. Fortunately, they now have a bios update that fixes the problem but the /PAE switch does incurr a slight performance hit on memory-intensive apps.

Hi all!
Ok, when the PCI-E Bus need the rest of the RAM, than i know where the rest of the RAM was placed :)
I have Bios-Version A01, now i want update it to A03. We have the Windows SBS 2003 installed. I think i can live with these problem :) The Bios-Update i make on weekend, i write back when something is changing. Sorry for my terrible english :)
