Help! My server doesn't detect all cores

Hi!
I come to the forum for help!

I have a server with this processor for my linux. "Intel(R) Xeon(R) CPU E5-2603 v4 @ 1.70GHz" and my Centos 5.9 does not detect all cores.

Someone could guide me! !!

You're running a massively out of date system that predates the hardware by at least 2 years. You should yum update to 5.11 and the latest kernel and then reboot into that and see if it helps. It may still not work as the processors may be newer than CentOS 5 supports.

Why are you installing CentOS 5 on such a new machine when CentOS 5 goes end of life in approximately 4 months time? There will be no more security updates after that.

I configured in the Bios this option

Processor x2APIC Support = Disable

and works ! with all cores !! :geek:
