Good thinking. I suspect Crucial would have sent you a replacement pair and asked for both back anyhow so you've likely saved yourself some time.

While I've dealt with bad RAM issues professionally often enough, I can only think of one time I've had a bad stick myself and that was a used machine I picked up on the cheap that had RAM in it that was some obscure brand.
