kjc5664 Posted July 26, 2006 Report Share Posted July 26, 2006 Mandrake 2006 Kernel 2612-22SMP Looking at the gnome system monitor. It looks as though. User memory is only utilized to 653MB of 1009.8MB before the system starts swapping. Is there a kernel parameter which lets me increase the amount of user memory used. I would like to use as much of my 1GB of memory for using swap space. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
ffi Posted July 26, 2006 Report Share Posted July 26, 2006 try the the 4GB-up kernel? Quote Link to comment Share on other sites More sharing options...
scarecrow Posted July 26, 2006 Report Share Posted July 26, 2006 The regular stock Mandriva kernels (incl. the smp one) do not utilize the full one gig of RAM you have, but "only" 890MB. To fix that, you either have to use a 4GB enabled kernel, or apply the 1GB patch (afaik present in the Con Kolivas patchset) and rebuild the kernel. Not 653 MB though- where did you get that info from? Some distros, like PCLInuxOS, come with a stock kernel already patched to use your one gig of RAM fully. I do have to warn you though that some apps, like VMWare, will fail to build the necessary modules with the 1GB patch applied, and some application-specific footwork is needed to bypass this issue.

Thanks for the reply. I came up with the 653MB. By observiing the GNOME system monitor values during the course of running my apps. It gets to 653MB. Then. Starts swapping. Unfortunetely. I can't use the 4GB kernel. As. I have a 940 dual core cpu. This I use an SMP kernel. Unless of course the is a SMP kernel built to use 4GB's.

RVDowning Posted July 28, 2006 Report Share Posted July 28, 2006 You might want to take a look at the explanation at the following page: http://forum.mandrivaclub.com/viewtopic.ph...ight=4gb+kernel It states: "Just in the interests of accuracy , the default kernel in the i586 edition can address up to 64GB of RAM. the -i686-up-4GB kernel can address up to 4GB. The only kernel limited to 1GB (or, more correctly, 896MB) is the -i586-up-1GB kernel which is included for old machines." HTH Quote Link to comment Share on other sites More sharing options...
