bsyuni Posted October 31, 2005 Report Share Posted October 31, 2005 I recently upgrade my memory form 2 Ga to 4 Ga. They are detected by CMOS but I can see only 3.6Ga under Mandriva 2005 LE. How can I use 4 Ga memory?

devries Posted November 1, 2005 Report Share Posted November 1, 2005 Is it an MSI mobo? Then it's a problem with the mobo. Nothing to be done about it. Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted November 1, 2005 Report Share Posted November 1, 2005 The only thing I can think of is if you install the kernel i686-up-4GB which may help resolve the problem, but I'm not 100% sure without being able to try it myself. First, you need to find out what version of kernel your running: uname -r then, find the corresponding i686-up-4GB kernel, and then install this. You will then get a lilo/grub boot menu option for this kernel. Boot from it, and see what you get. Quote Link to comment Share on other sites More sharing options...

The kernel that I am running is 2.6.11-6mdksmp I check the kernel, It compiled 64Ga memory with 8 cpus support. Quote Link to comment Share on other sites More sharing options...
Shadowchaser Posted November 5, 2005 Report Share Posted November 5, 2005 try upgrading your kernel to 2.6.12-12mdksmp Quote Link to comment Share on other sites More sharing options...
AussieJohn Posted November 5, 2005 Report Share Posted November 5, 2005 I think your 4Gb memory is detected AOK. The apparent discrepency may have something to go with the way the memory value is stated. Something about bytes and bits. I have never been able to fully understand it but apparently it is not something to worry about. It could also have something to do with the kernel. I believe you need a kernel that is specifically for memory of 4GB and above. I think this is the main reason. Cheers. John. Quote Link to comment Share on other sites More sharing options...
jboy Posted November 5, 2005 Report Share Posted November 5, 2005 Is it possible that part of the discrepancy could be due to shared video memory, thus reducing the amount of memory that Linux detects? Is your video device integrated on the motherboard - if so, how much RAM is devoted to video (you can tell from the BIOS settings and possibly the boot up messages)?

Cannonfodder Posted November 6, 2005 Report Share Posted November 6, 2005 Why don't you find some alternative tool for reporting memory and see what it says? Quote Link to comment Share on other sites More sharing options...
