Windows Server 2008 Enterprise 32-bit supports up to 64GByte RAM, Windows 2003 Enterprise 32-bitup to 16GByte RAM. Best regards Klaus

I thought PAE was enabled by default in 2008. Are you not seeing all the memory in perfmon? tgc

Hi I agree with 1a-archiv and Tim. Typically, Windows server 2008 Enterprise 32bit can support 64GB RAM. By the way, the boot.ini has been replaced with Boot Configuration Data (BCD). So you have to use "BCDEdit /set pae ForceEnable" command to set the pae boot entry option. For more details, please refer to: Physical Address Extension: http://msdn2.microsoft.com/en-us/library/aa366796(VS.85).aspx BCDEdit /set: http://msdn2.microsoft.com/en-us/library/aa906211.aspx I hope this helps.

I have Server 2008 Enterprise running on a 32-bit processor and cannot get the system to recognize more than 6GB of RAM. If I put in 8GB, the system powers on to the BIOS (which recognizes the 8GB of RAM) and then restarts itself at the point where normally it would start to load the OS. If I downgrade to 6GB of RAM, the system boots as normal.I have already tried enabling PAE using BCDEDIT.Any ideas?Jeff

This sounds that your RAM may be damaged. Did you enable RAM check in BIOS? Are all RAM Chips form the same vendor and type? Did you use Win2003 Enterprise before, where you got 8GB? With 6GB: What RAM size shows Computer Porperties windowand what size Task Manager? Without PAE Option 8GB where shown in Computer properties but only 4GB in Task Manager. With PAE Option 8GB are available also in Task Manager. best regads Klaus

Yes, the BIOS checks my RAM as part of the POST Yes, all of the RAM chips are identical. When I try 2GB x 4, Windows does not boot, but when I do 2GB x 2 and 1GB x 2, it works fine. I have also tried the latter configuration with both pairs of 2GB modules and Windows boots fine to rule out a defective module.No, I only had 2GB while running 2k3 Ent.WIth 6GB, Computer Properties shows 6GB and task manager shows 5886MBThanks,Jeff

Does your MainBoard support 8GB of this type RAM? best regards Klaus
March 27th, 2008 12:00pm

Yes, the BIOS shows 8GB of RAM. The manufacturer's specification is also published as 8GB of RAM max.Thanks,Jeff

Have you checked the ranking of the memory. some servers only support a limited amount of RAM Ranks. I'd love to be able to explain to you about Ranknig but I'm no expert on it but there is somethign on it here:- http://en.wikipedia.org/wiki/DIMM#Ranking We had a similar issue here where I work. We tried to upgrade the ram and fill all the slots on a few servers (HP DL380's)but we exceeded the RANK limit for the motherboard so it's wouldn't boot.

Physical Address Extension (PAE) is a processor feature that enables x86 processors to access more than 4 GB of physical memory on capable versions of Windows. Certain 32-bit versions of Windows Server running on x86-based systems can use PAE to access up to 64 GB or 128 GB of physical memory, depending on the physical address size of the processor.
