I ordered 2x4GB Crucial Ballistix RAM from Amazon to fit in my Gigabyte GA-Z77-D3H motherboard.
One of the sticks fits fine. But the other one just won't go in. Even though it looks the same, I think it is physically marginally thicker than the one that works, but I just don't know why it won't fit. Its not a slot issue because I've tried putting them both in different slots and the one that works fits in any of them no problem.
The thing is, I can't just return it to Amazon because I'm an international buyer and the shipping costs would probably be more expensive than the RAM itself. That, and I don't want to wait another couple of weeks for a replacement.
All that being said, is there anything I can do to salvage this RAM or do I have to buy another set? If I do have to buy another set, can I just buy 1x4GB of another brand or does it have to be the same? Or can I contact Crucial support in my country to get a replacement? What other options do I have?
