Guest awshirley Posted December 23, 2007 Share Posted December 23, 2007 (edited) I just upgraded the hardware in my linux computer to a Athlon 64 X2 and 5 GB of ram. What kernel should I install to take advantage of the dual core processor and all the ram? I'm currently running kernel-2.6.17.16 on Mandriva 2007.1 Spring and the most ram it sees is 3 GB. All help is greatly appreciated... Thanks! Edited December 23, 2007 by awshirley Link to comment Share on other sites More sharing options...
dexter11 Posted December 23, 2007 Share Posted December 23, 2007 You need one of the smp kernels. Don't know about the memory though. Link to comment Share on other sites More sharing options...
Greg2 Posted December 23, 2007 Share Posted December 23, 2007 For the Mandriva 2007.1 version, I believe you needed the kernel-enterprise variant, to allow support for more than 4GB of RAM. I also don't believe that there was a 64-bit kernel-enterprise variant available. Link to comment Share on other sites More sharing options...
scarecrow Posted December 23, 2007 Share Posted December 23, 2007 I assume you are running the x86_64 Mandriva version- else you may forget 4+ G of RAM. Link to comment Share on other sites More sharing options...

scarecrow Posted December 23, 2007 Share Posted December 23, 2007 (edited) No, I'm running the 32 bit version. So, either install the 64-bit one, or forget utilizing more RAM than what you've got now. The issue is code specific (memory mapping on 32-er bytecode)- and it applies for ANY OS, not just Linux... see here: http://blogs.msdn.com/hiltonl/archive/2007...am-problem.aspx The max. RAM an application is using is 2G, and the rest is reserved by BIOS. You may even have to install newer mainboard BIOS after upgrading to 64-bit OS, or replace your older chipset/mainboard completely to be able to achieve that... And in any case, it's highly dubious if you will be able to utilize 5GB of RAM. For 4 GB (full utilization) or 8 GB, the answer is most certainly positive. 5 GB is simply enough not a natural RAM upgrade step- you should have asked before upgrading.
