most times the brand of the ram wont matter unless u r really into overclocking...
most brands of ram like dynet,simmtronics,zion or transcend will last longer than say ur procy and mobo.....
cosair and kingston and stuff are a level better...they are gud but come at a premium which may or not may be justified depending on the usage...
10 years warranty is nice to have but well....u pay a premium for it....that is something u need to decide....
pick up any ram which comes with a 3 year warranty and fits in ur budget....
transcend i wud hv always prefer mainly because i had gud experience with it....
