[SOLVED] Support for 2 dual-core processors?

Hello, I am rather new to linux in general. I am currently running Ubuntu 64 but wanting to switch to Arch 64. I have 2 3Ghz dual-core amd64 cpus and 8GB of ram. I am wondering whether arch (or linux in general) will support 2 dual-core cpus? If so how does one go about this or does it happen automatically? And how can I check to see if both cpus are working? I have heard from a friend that I would have to compile a kernel to get support for this. Which kernel would I need? I havent managed to find a guide on this topic yet, so if someone knows of one please post a link. Also arch 64 just automatically would support the 8GB ram (4 2GB sticks)? Any help would be appreciated. I would be happy to provide any more information that is needed about my system ect..[]

Re: [SOLVED] Support for 2 dual-core processors?

The configuration should work fine with the stock kernel. To check that all the cores are detected, simply run this from a terminal:

cat /proc/cpuinfo

If it lists four processors, you're good. Your memory will be fine for sure under 64 bit. To check:

free -m

It will be the first entry (in megabytes).

And welcome to the forums.

Re: [SOLVED] Support for 2 dual-core processors?

Thank you kindly. It does indeed show four cpus and 8GB of ram in Ubuntu 64 so I should be good to go.  How would I go about marking this as solved? Just noticed that it shows four cpus and shows all of them having two cores, is that the normal way that it is listed?

If you are running Gnome and have gnome-system-monitor installed, it will display all the information you need and then some.

Ah, yes. Didnt realize that I had a system monitor but that works nicely too. Thanks.

Would you paste the output of cpuinfo?

In system monitor it is using about 2% of cpu3 and 2% of cpu4 and 0% of cpu1 and 2.
