To my thinking, I could understand if it was 2 sticks out of 12 (yes, 12, PC3700 = 2 sticks, twice. PC3200 + 4 sticks also twice) but to have issues with 12 sticks out of 12 sticks. That's just too high of a failure rate for me to want to spend money on that brand ever again.
If you bought 6 hard drives and they all failed then got 6 more on RMA and they started screwing up would you be very hip on spending money on that brand again? Or 6 motherboards, same thing?
I really doubt that after having 12 out of 12 of anything in a row fail on you that you could honestly say "Hey, I think I'll take a chance on buying Brand X again and see how well my luck runs." I just can't see getting burnt like that again.
