This is really bugging me. Story: I changed cases (for better cooling) and upgraded RAM from 1 GB to 4 GB. Ever since then I have been getting all kinds of crashes/logouts. No errors logged because I have been too lazy to have SELinux allow the KDE crash handler to log, cause it won't by default. I decided to reinstall Fedora Core 8 and I continue to get these problems.

Also, I had a random logout when I was in the middle of downloading update packages and now I can't download the last 18 or so. Memtest showed that there were no errors in my memory after running it over night.

Another thing, I am running a 32-bit kernel of fedora. Fedora only maps/detects ~3.5 GB or so. Would upgrading to a 64-bit kernel resolve this?

Can anyone please help me with these problems. Thanks in advance.

My specs:
Intel Core 2 Duo E6400 (~2.13 GHz)
4 GB or RAM (two 512 modules, one 1 GB module which are both from Wintec and one 2 GB PQI module all with 5 Cas latency)
Nvidia GeForce 7600 GT (256 MB of GDDR3)
2 Western Digital 320 GB SATA drives.

Use a PAE kernel is sticking with a 32-bit OS. The 64-bit OS and kernels do not have this 3.5-GB memory issue.

It is not a good idea to have such a mixture of memory, as a suggestion get yourself another 2-GB memory module and replace all the rest of the memory modules. You could leave the two 512-MB memory modules installed, but they should go after the two 2-GB memory modules (for a total of 5-GB of ram).

Thanks, ill try that.
