Memory upgrade driving me mad!
Any insight you can offer massively gratefully received - I am losing my sanity!
I am running linux on a dell dimension 3000 that came with 512MB of RAM, installed in 2 x 256MB slots. On dell's website it says that the memory is upgradable to 2 x 512 slots, but on a reputable memory supplier website it says (and also according to my sysadmin friend at work) that it's OK to put in two 1GB - the only reason dell doesn't say you can do this is that the 1GB cards weren't around when they wrote the docs..
But since I put the memory in, everything seems to work fine for about 2 hours. Then the keyboard mysteriously locks up and tomcat crashes. Does this sound like the kind of thing installing new memory could cause? Is there a parameter I need to tweak in Red Hat somewhere? I've put the old 2x256 memory back in and it's fine again (but slow!). I don't want to give up on 2GB of memory on this machine - does anyone know if there's something simple I can do to fix it, or at least to see the errors? (I looked in /var/log/messages, catalina.out etc - no trace of an error, everything just stops working..)
Thank you so much if you can offer some guidance!
