I remember an application which would identify the bad memory cells and isolate them so that your machine could happily carry on using the rest of the memory - unfortunately just like yours my memory is not what it used to be . . .  ;-)

I've googled but can't find it.

Yes, I found a kernel patch that does that. It allocates all the bad
memory sectors in kernel space permanetely, so they can't be used.
But, I found it too late. The memory is so bad now that it doesn't
even tries to boot. It just stops after detecting all IDE devices.
Gonna have to buy new memory boards...

when your ram becomes worse in some few days, there is a great chance, that 
not the ram, but the PSU is the culprit.

When a PSU is becoming weak, it is not able to hold the voltages at sufficient 
levels - lockups and ram-errors are then common problems.

I'll test the memory chip on another computer and see if it works...

No, the memory is wasted. :(
