Problems installing memory upgrade with 8.10

Asked by huehueteot

I recently purchased an additional 4 GB of DDR2 SDRAM (DDR2-800 PC2-6400 2GBx2 CL5-5-5-15 1.8V. With the new memory installed the Bios sees it and reports it as good. The Ubuntu 8.10 that I am running will not boot however. I tried to go in and use the recovery mode. I was able to get in and to log in and run free -mt which again reported the full 6 GB of ram but I am not knowledgeable enough to do anything after that. I am using a homebrewed system with an Asus AM2-VM motherboard. It runs fine with the original 2GB or ram I got it with (I am using it now to do this) but still won't boot up Ubuntu if I have the additional 4GB either alone or in tandem with the original 2GB. There is one difference in the boot process that I get. With the original 2GB I get a message that says something about "...appature larger than 4GB...ignoring." With the additional 2GB I get 4 lines of text that go by faster than I can read them. I was hoping that this ram upgrade would solve some of the memory use issues that the system is suffereing and the consequent slowdowns that occure.

So far as I know I am running the AMD 64 bit version of Ubuntu. How do I find out which version I am running? I do know that things like adobe flash won't run because they are i386 instead of i686 which I think is a 64 bit version.

Have you installed Ubuntu inside Windows using the Wubi installer? or did you boot up from the Ubuntu Cd and install using this approach?
https://help.ubuntu.com/community/WindowsDualBoot

One way of telling is if the boot menu has a lot of Ubuntu options or just 1 option for Ubuntu and 1 for Xp?

Please let me know and we can take it from there.
Good luck and regards from
Tom :)

Tom:

Ubuntu
is the only operating system on this machine.? When I say it
doesn't boot up here is what happens:

The bios post process
completes, grub offers it's choice, the screen shows the four lines
of text that I can't read then the Ubuntu logo appears and the orange
bar completes and then nothing it just hangs.

The previous
message suggested using uname -a to determine the type of Ubuntu I am
running and the results of that are:

Linux
huehueteot-PC 2.6.27-14-generic #1 SMP Fri Mar 13 19:54:51 UTC 2009
x86_64 GNU/Linux

hope this helps.

Are the 4 options roughly like this?

Ubuntu 8.04.2, kernel 2.6.27-14-generic
Ubuntu 8.04.2, kernel 2.6.27-14-generic (recovery mode)
Ubuntu 8.04.2, memtest86+
err, i can't remember whar else might be here

If not then you should be able to access that menu by pressing escape just after the bios stage and early on in the grub stage.

I think the x86_64 shows you have the 64bit version which should cope with the extra ram quite easily. i've never had much luck with the 64bit version tho and prefer 32bit even on my 64bit machine. However, it shouldn't be causing this trouble.

 Tom:

Are you referring to the Grub Options?? If so there are many more options than that.? I have upgraded this machine from 7 something to the two 8 versions (I currently run 8.10) and there have been a bunch of kernel refreshes that all offer a regular boot and a recovery mode boot.? The four lines of text that I refer to occur after the grub menu goes away and I think that they are error messages or messages from the motherboard/Bios but I can't read them because they go by so fast and pause doesn't seem to work for them (they do seem to refer to the ram installed).? One seems to talk about loosing access to 64 MB of ram for some reason.? I have gotten the recovery mode up with the upgrade ram installed with the original ram and without and in both cases free -mt reads the ram just fine (6GB with the original and 4GB without it) but I can't get the regular boot up to complete and I don't know what to do with the recovery mode.? The regular boot process hangs after the orange bar goes away.? Hoping that there was some sort of process that needed to time out I have left it sit for a long time yet nothing ever happens after the orange bar goes away.

The last answer to my question didn't seem to me to provide anything that I could do. Can anyone out there tell me what could be causing the problem and suggest things that I could do to fix it? For example are there things that I could do in recovery mode that could tell me why Ubuntu won't load the login page or what is causing the halt in the system at that point? I know that there are log files that record changes in hardware and software configurations and that log errors but I don't know where they are nor do I know how to access them in regular or in recovery mode? For instance is it possible to "manually" load gnome in recovery mode? Is there a method of opening more than one terminal? Can I see what the errors were in this mode where I restored the system to it's original configuration? Is there a manual for the recovery mode? Thanks in advance for all the help.

Hi :)

Have you been able to test the new Ubuntu 10.04 before it gets officially released?
http://www.ubuntulinux.org/testing/lucid/beta1
Trying it as a LiveCd or as an extra dual/multi-boot would be ideal. Developers and everyone are keen to try to iron out any problems before 10.04 gets officially released so you might find faster & more effective answers to your bug reports which would make 10.04 work better on your system for you

Thanks and regards from
Tom :)

Can you help with this problem?
