Hello!
Where can I see processor speed and RAM memmory in Linux RedHat 7.2 (graphical environment)? Which options do I have to select?
Thank you!

Installing a program like gkrellm would take care of this.

i dont know about the graphical interface but
you can try
cat /proc/meminfo
cat /proc/cpuinfo
from the terminal

System monitor under sytem tools provides some info

or dmesg | grep CPU or mem from command line

[genlee]

top or vmstat are very useful as well.

hey..

I wanted to know how we can get to know the last accessible ram address. Because in x86 Arch..in some RAM , there exist some memory holes, which are used by the BIOS, and kernel does not have the access to that.

devmem_is_allowed() function could be used to check the valid ram access. I am still fiddling around with the codes for x86.

The max_pfn does not points to the last physical address.
If anybody finds it..please share it across.
