Thanks Leonard,
 
Thanks for the immedite reply . apprecite.
actually many post s say the PAE kernel required for addressing more than 4 gb ram . but since my server already detects 32 gb ram , detecting 64 also should not be an issue..
 
but just wondering why??.
 
 
 
regards

I have no idea why your server doesn't see the extra 32GB, but you do
*not* need a PAE kernel. PAE is a hack for 32bit system to use more than
4GB of memory. Your machine is a 64bit system, so you don't need a PAE
kernel on it.

Leonard.
