I've just bought the both 4 GIg rams ;/ I don't think its wrong with them. I did'nt buy them from, eBay or something. I bought them from a real market.Run a memory test I'd say. Segmentation faults just mean it tries to access memory that doesn't exist. That might also point towards corrupted Windows files, or maaaaaybe a bugged revision, but that's unlikely.
Take out half of the memory, try again, if it still fails, try to remove the other half (while placing the first bits back..). You can find the broken memory card like that. It might also be a broken memory attachment location of course. Or a messed up CPU.
That doesn't mean they are perfect. Very possible new memory cards have flaws in them.I've just bought the both 4 GIg rams ;/ I don't think its wrong with them. I did'nt buy them from, eBay or something. I bought them from a real market.
