Thumbs down Mandrake 10 not detecting all my RAM!


Only ~880 of my 1024MB of DDR RAM is being detected by Mandrake. I've gone into the control panel -> Boot -> Boot Loader -> Advanced and manually inputted my RAM amount. but I do not think that has helped, since my memory manager still only reads ~880MB.

Any suggestions? Please keep it as simple as possible, as I'm a Linux Newb.

If I have to edit any config files, please give me their exact locations.

Thanks!

Hi

I have experienced this problem before after loading more RAM into my mobo. It may be that the fix is not with KDE or Linux at all but with the BIOS settings or with chip incompatibility/damage. Not knowing what board you are using it is hard to give specific directions, but I'd suggest that you power down your machine, open it up and (a) make sure that your RAM chips are properly seated (i.e. both clasps are firmly down and that the chip isn't able to be wriggled, etc) and then (b) power up and enter your BIOS (either holding down del or the F2 key on boot) and look for something in the menu that will allow you to calibrate your RAM. Once you've done that, reboot and you should be fine.
If this doesn't work, it could be that you had a dead or an incompatible chip. This is what fixed this problem for me. This requires that you remove one chip and boot up - if that chip is registered (i.e. allow a full boot up into your X windows) then that is fine, so test the other chip(s). If all the chips work separately, then you are more than likely facing an incompatibility issue. Try and get chips that are all from the same manufacturer with the same specs.
This fixed the issue for me. I hope it works for you.

all is fine, you are using an inappropriate kernel.
you have to install one of the 'up4GB' or 'enterprise' kernels.

same happened to me when i upgraded from 512 to 1g with mdk installed already.
on a fresh install, mdk chooses the up4GB kernel for you.

Thank you very much, I actually already had a up4gb kernel, but I decided to update it. However at boot I would get no screen...well, it turns out there was no vga mode set in Lilo.conf! So I added the line vga=788 to lilo and now it's all peachy, all my memory is detected.

However can I get rid of some of the other kernels on the lilo boot loader? Can I do this just by removing them from lilo.conf or do I need to somehow physically delete them? It's kind of cluttered with all those things I dont need or use.

Lastly, I noticed on bootup some of the things [FAILED] even though it booted up to KDE just fine....I think it failed at some "loopback" option, does that matter?

Thanks again!

I only have a few up4gb kernel versions, and removed all the others
using urpmi (or the mandrake control center to start the package maintenance application).

using the package removal ensures that not only the /boot/vmlinuzXYZ and initrdXYZ..img are removed but that
the modules for that kernel version go too.

sorry, don't know about your loopback failure
cheers,
Edo

Ok, which is the more recent kernel? They both have the same date but different version #s?

kernel-i686-up-4GB-2.4.22.35mdk-1-1mdk RPM for i586

or

kernel-i686-up-4GB-2.6.3.14mdk-1-1mdk RPM for i586

? I installed the 2.4.22.35 one. I need to know this because I'm about to uninstall the 2.6... one if it turns out to be a earlier version.
