Update:
I RMA'd the old Transcend and I mentioned before. I got the new one 2 days ago and SUPRISE it's the "Elpida" chip again! I ran memtest and got 2 errors after 3 hours. I was about to send it back too, but I decided to test it again, just to see. After 8 hours of a second test, no errors! I'm going to try again later today and just let it run. If it is stable then maybe I'll keep it. It doesn't really matter though because Transcend gives a lifetime warranty. I just decided to deal with Newegg with the first stick and get a refund.
