I just find this URL, I would like to know what is the max supported memory of redhat 5 , from the table , it is 16G , may I know does I have make misunderstand ?

thanks

Code:

x86     16GB
x86_64 	 1TB

it depends on your system. Is it a 32 or 64bit architecture?

That is for 32-bit hardware. For 64-bit hardware the limit is shown as 1T - it is likely you could use more if your motherboard allows it.

thanks reply ,

when I use the below command in my redhat 5.8 , it show support 1536G not only 1G , is the 1536G means max hardware supported , not redhat suppｏｒｔｅｄ　？

#dmidecode |grep -i "Maximum Capacity:" | uniq
Maximum Capacity: 1536 GB

see notes on that page. redhat itself does not support anything, it depends on the kernel you have and the hardware you use.
see also man dmidecode:

Code:

dmidecode is a tool for dumping a computer's DMI (some say SMBIOS) table contents in a human-readable format.
...
 The DMI table doesn't only describe what the system is currently made of, it also can report the possible evolutions (such as the fastest supported CPU or  the
       maximal amount of memory supported).

so dmidecode reports 1.5 TB, so your hardware could use that, but the kernel of RH can handle max 1 TB.

What parts of the answers you got in your OTHER thread are you having problems understanding???

Want to know about your server? Then READ THE MANUAL. Want to know EXACTLY how many slots are used? OPEN THE SERVER AND LOOK. These are simple things...what's the problem in you doing them?
