But on his platform he has the choice. I'd go with x86_64. -- If stupidity got us into this mess, then why can't it get us out? - Will Rogers -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

If you intend to ever put more than approx. 3 GiB of memory into the machine you should go for x86_64. Philipp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Currently running 11.1 openSUSE. "uname -i" results in i386. I have 8GiB of memory "free -m" shows total memory of 3291 Does this mean all my memory is NOT being used? Yast hardware information says the CPU is "Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33Ghz xosview shows 4 processors. When I upgrade to 11.2 should I use the X86_64?

Looks that way. install the PAE kernel from the repos and you should see all RAM again... free -m on my system (64bit install with 8GB RAM) shows: total used free shared buffers cached Mem: 8000 3150 4849 0 95 1536 -/+ buffers/cache: 1518 6481 Swap: 3906 0 3906

If you've got a 64 bit CPU, it makes sense to use a 64 Bit kernel. I've been running 64bit for a while now.. works fine. Tehre isn't really a marked performance inprovement, but things like RAM over 3.2 GB is no longer a prob (and from what I've read, the PAE kernel struggles when you have more than 8GB of RAM).

I'm a little bit confused to say the least. I check the installed rpms with " rpm -qa | grep kernel" and found not only the "default" kernel installed but also "kernel-pae-2.6.27.37-0.1.1". Since I'm currently running the "default" kernel, how do I switch to the "pae" kernel. Also, is there a command to determine if my cpu supports 64bit. Finally, is the pae kernel 32bit supporting memory above 3.2Gb? Thanks for any help.

Generally, it should be set up as a selectable kernel in Grub - assuming you installed the kernel via YaST (or it was auto installed along the way.. like on initial install of 11.1... which if I remember correctly should have been done on install... I think).
is there a command to determine if my cpu supports 64bit. Finally, is
The Q8200 is a 64 bit quad core Intel http://ark.intel.com/Product.aspx?id=36547
the pae kernel 32bit supporting memory above 3.2Gb?
The PAE 32 bit kernel supports RAM above 3.2GB. Your 8GB of RAM will be "visible" and usable with a PAE kernel. On a side note... i seem to remember something about the default 32 bit kernel supporting PAE so there was no longer a need to specifically select the PAE kernel... but I could be misremembering... it's been a while since I moved to 64 bit kernels.

I was lead to believe by postings on this list a year ago that OpenSuse was smart enough to select the proper kernel based on machine configurations?
