Ok, got it. Any other go aheads to return even the good one back?
Why would it be better to buy two new ones as opposed to just keeping the now good one and buying another new one?
Many memory manufacturers require you to RMA memory bought in sets so that they can replace with memory that has been tested to work in the same set (2, 3, or 4 sticks). If you are buying more memory it is best to buy identical memory if possible.
