Dutch Posted February 16, 2006 Report Share Posted February 16, 2006 I'm running a 2006 Powerpack on a P4 3.2 machine, which has Hyperthreading - using kernel 2.6.12-12mdksmp. Would there be any issues at all installing 1GB of RAM on an smp kernel ? Thanks for any pointers! Quote Link to comment Share on other sites More sharing options...
nchancock Posted February 16, 2006 Report Share Posted February 16, 2006 I've got a GB running the SMP kernel right now. No problems so far... EDIT: oops, guess I should update my signature :) Quote Link to comment Share on other sites More sharing options...
Dutch Posted February 16, 2006 Author Report Share Posted February 16, 2006 Thanks for the info. I didn't want to splash out £60+ and find out I had to change kernel! Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted February 17, 2006 Report Share Posted February 17, 2006 A bit of technical info on how to make sure all is OK with your running kernel. Normally, for 1GB you'd be fine. The problems come when you want to use any more of this. Between 1 and 4GB, you need the kernel to have the 4GB option enabled. For greater than 4GB you need the 64GB option enabled. Mandriva has i686-up-4GB kernels which you can upgrade to, but I think there is probably no need to. Why I say this, is you can check your /boot/config file to see if these options are enabled. Here is a sample from mine: [ian@europa boot]$ cat /boot/config | grep CONFIG_HIGHMEM # CONFIG_HIGHMEM4G is not set CONFIG_HIGHMEM64G=y CONFIG_HIGHMEM=y as you can see, the 4GB is commented out, and the 64GB is enabled by default. Therefore, in my system I could run 2-4GB no problem, or even 32GB no problem without having to change the kernel. Hope this helps. Quote Link to comment Share on other sites More sharing options...
Dutch Posted February 17, 2006 Author Report Share Posted February 17, 2006 Thanks. My /boot/config shows: - # CONFIG_NOHIGHMEM is not set # CONFIG_HIGHMEM4G is not set CONFIG_HIGHMEM64G=y CONFIG_HIGHMEM=y ......so I guess I've got plenty of leeway! :) Once again, thanks for your help.
