For months now I've been plagued with the erratic shutdown of my computer and the appearance of the "blue screen of death". A suggestion from Microsoft recommending the checking of hardware put me on to checking my memory cards (2 of 256 mb and one of 512 mb). I did the checking with "Memtest". When I checked with all three slots occupied, I kept getting error messages (at address ffffff7f) so I tried each memory card individually, each one separately in each of the three slots: all checked out to be faultless by themselves and in twos. However, when using all three slots together, I get the memory error message--no matter what order they are placed in. Right now, I'm working with only two cards (512 and 256) in slots 1 and 3, with the middle slot empty. Running Memtest showed no problems.
Is this "proof" of a faulty motherboard (mine is an Asus P4U800-X)? If so, is a fault like this covered in the guarantee?

Jump to PostHave a read through your motheboard's section on installing memory (download a copy from asus if you havn't got one).
Some boards have 'quirks' with their slots.
My board will run 3 slower sticks, but for high speed dual channel it's recommended I only use 2 slots.

Jump to PostSOme boards work like that, if they have four slots and if you want to use more than 1 slot at a time, u have to use either the pair like slot 1&3 or Slot 2&4. It probably would give an error if you have memory installed in Slot 1&2 …
Jump to Postwell well well, congratulations to you then. Looks like you ll be busy for a bit, but try the suggested solution when ever you get time for it and let us all know how you get on.
