My ram are not that old 4 moths old i have a hyperx fury 4gbx2 work fine until now.
If you have 2 sticks of 4gb, check the manual, 1 of the memory slots has too be used over the other 3, try both sticks in that slot, one at a time, if one boots and the other doesnt, then you know you need to RMA the ram.
