I won't say that. It's too early to suggest it.TPA wrote:top socket is bad would be my guess. mobo replacement for that!
If the factory memory worked fine in both slots then there is no problem with any of the slots.
However to make it firm, do this:
Run your machine exclusively on each slot (install the user bought in only the slot where it works) for few hours and do some "heavy work" on your system, if BSOD comes on only with user bought and not with the factory installed then the former is bad, if vicerversa then it would be time to get in touch with lenovo.
