The chip on trident is selected elpida BBSE....

Are very good in cas 9, because they are very stable and have a good signal to return on the IMC. This chip with good i7 are stable with low VTT in many mainbaord

the only recommendation, with all the chips Elpida low volt, don't give more 1.7 volt modules in daily, if you do not want to kill them in short time.....
