All of the brands you named make very good memory and Crucial is one of the best. You can get a bad stick from any of them. The good news is that most have a lifetime warranty and will replace it. I just got 2 Gig today from OCZ because one stick of two matched sets (4G) was bad when testing in my P35 machine.
For the 410 with the limitation of PC2-6400, I would focus on the timings and latency that memory runs at stock speeds. Lower latency CAS 3 or 4 is probably going to give you better perfprmance, but to be hosnest don't expect a big boost from the move from 667 Mhz to 800 Mhz.
And RMA that abd memory with Crucial. They will replace it.
