Cannot see extra Memory
Hi,

I upgraded the physical memory on my RHEL5 server (BL460cG7) from 32G to 128G. When I rebooted the box I can see from the "hpasmcli" that the 128G memory has installed correctly.

However when I run a "free" command I can only see 64G of physical RAM? Is there a restriction on the max amount of memory a RHEL5 32-bit server can use? If not is there a parameter that needs updating in order for the extra memory to be seen by the OS?

R,
D.

32-bit x86 has hardware limitations of 64 gigabytes. You're using a 64-bit processor with a 32-bit kernel why?

It's time you drop 32 bit RHEL and go for 64 bit one. There's no two way about it!
