Nothing wrong with Kingston Valueram
I've called kingston to inquire about the differences and from what they told me, the standard series are tested for use in specific systems. The ValueRAM series has not been tested, but the assembly and quality of parts are exactly the same. They come from the same assembly line. They are cheaper because less time has been spent with compatability testing. Most of the time, as long as the ram meets the timing and voltage requirements, it should be fine
Valueram also has lifetime warranty like the standard series.
