I bought my R5 1600 on Amazon. I know that amazon gives 2 years warranty (I think??). So 2 year total warranty or do I have third year which means sending in third year directly to AMD?
2 years total, the first 30 days are handled directly with the retailer, after that it's through AMD themselves.
So if I want to RMA my CPU because segfault problem I can only send it directly to AMD?
