Funny, Transcend a while ago gave me some 800mhz and 1066mhz axeram to test, and a couple days ago i got their new 1200mhz.
800mhz uses an unknown type of chip, transcend put their own name on the chips.
1066mhz uses D9GMH, as well as their 1200.
I'll soon be posting my fun with the 1200, they look beautiful!
