Would I be right to guess that that you > inserted the new cards in such a way that the low memory is new RAM? No. All the memory is new RAM. I originally had 2x256MB, and I replaced those with 3x1GB. Sorry if the Subject header was a bit misleading. > I suggest you try taking out that lowest card, and see what happens > then.

When I had posted the message I had only let it run through all tests once. I have since let it run for about 18 hours, where it came up with a single error (as reported in my reply to Ken). > You could try sending me all your "Bad page state" messages, > to check for correlations.
